The query execution happens on all get methods like

$this->db->get('table_name');
$this->db->get_where('table_name',$array);

While last_query contains the last query which was run

$this->db->last_query();

If you want to get query string without execution you will have to do this. Go to system/database/DB_active_rec.php Remove public or protected keyword from these functions

public function _compile_select($select_override = FALSE)
public function _reset_select()

Now you can write query and get it in a variable

$this->db->select('trans_id');
$this->db->from('myTable');
$this->db->where('code','B');
$subQuery = $this->db->_compile_select();

Now reset query so if you want to write another query the object will be cleared.

$this->db->_reset_select();

And the thing is done. Cheers!!! Note : While using this way you must use

$this->db->from('myTable')

instead of

$this->db->get('myTable')

which runs the query.

Take a look at this example

this code works with me

 ImageView carView = (ImageView) v.findViewById(R.id.car_icon);

                            byte[] decodedString = Base64.decode(picture, Base64.NO_WRAP);
                            InputStream input=new ByteArrayInputStream(decodedString);
                            Bitmap ext_pic = BitmapFactory.decodeStream(input);
                            carView.setImageBitmap(ext_pic);

DEMO

You must use the multiple box-shadow; . Inset property make it look nice and inside

div {
    box-shadow: inset 0 12px  15px -4px rgba(31, 73, 125, 0.8), inset 0 -12px  8px -4px rgba(31, 73, 125, 0.8);
    width: 100px;
    height: 100px;
    margin: 50px;
    background: white;
}

At least as far back as MySQL 5.5 you can use format:

SELECT FORMAT(123456789.123456789,2);
/* produces 123,456,789.12 */

SELECT FORMAT(123456789.123456789,2,'de_DE');
/* 
    produces 123.456.789,12
    note the swapped . and , for the de_DE locale (German-Germany) 
*/

From the MySQL docs: https://dev.mysql.com/doc/refman/5.5/en/string-functions.html#function_format

Available locales are listed elsewhere in the docs: https://dev.mysql.com/doc/refman/5.5/en/locale-support.html

Operating system commands have exit codes. Look for Linux exit codes to see some material on this. The shell uses the exit codes to decide if the program worked, had problems, or failed. There are some efforts to create standard (or at least commonly-used) exit codes. See this Advanced Shell Script posting.

Because the original question doesn't mention how the variable was set, and because I got to this page looking for this specific answer, I'm adding the following:

In C shell (csh/tcsh) there are two ways to set an environment variable:

1. set x = "something"
2. setenv x "something"

The difference in the behaviour is that variables set with setenv command are automatically exported to subshell while variable set with set aren't.

To unset a variable set with set, use

unset x

To unset a variable set with setenv, use

unsetenv x

Note: in all the above, I assume that the variable name is 'x'.

Dim a As String = Microsoft.VisualBasic.right("I will be going to school in 2011!", 5)

Another answer would be very similar, but wouldn't need to set the text of the TextView twice

TextView TV = (TextView)findViewById(R.id.mytextview01);

Spannable wordtoSpan = new SpannableString("I know just how to whisper, And I know just how to cry,I know just where to find the answers");        

wordtoSpan.setSpan(new ForegroundColorSpan(Color.BLUE), 15, 30, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);

TV.setText(wordtoSpan);

This can be a quick hack to connect hive and python,

from pyhive import hive
cursor = hive.connect('YOUR_HOST_NAME').cursor()
cursor.execute('SELECT * from table_name LIMIT 5',async=True)
print cursor.fetchall()

Output: List of Tuples

SELECT * FROM `calendar` WHERE DATE_FORMAT(startTime, "%Y-%m-%d") = '2010-04-29'"

OR

SELECT * FROM `calendar` WHERE DATE(startTime) = '2010-04-29'

I've noticed bizarre behavior with Eclipse version 4.2.1 delivering me this error:

String cannot be resolved to a variable

With this Java code:

if (true)
    String my_variable = "somevalue";
    System.out.println("foobar");

You would think this code is very straight forward, the conditional is true, we set my_variable to somevalue. And it should print foobar. Right?

Wrong, you get the above mentioned compile time error. Eclipse is trying to prevent you from making a mistake by assuming that both statements are within the if statement.

If you put braces around the conditional block like this:

if (true){
    String my_variable = "somevalue"; }
    System.out.println("foobar");

Then it compiles and runs fine. Apparently poorly bracketed conditionals are fair game for generating compile time errors now.

You haven't really said much about what sort of random string you need. But in any case, you should look into the random module.

A very simple solution is pasted below.

import random

def randstring(length=10):
    valid_letters='ABCDEFGHIJKLMNOPQRSTUVWXYZ'
    return ''.join((random.choice(valid_letters) for i in xrange(length)))

print randstring()
print randstring(20)

If you use a comma inbetween the strings and the variable, like this:

print "If there was a birth every 7 seconds, there would be: ", births, "births"

Simply \newpage or \pagebreak will work, e.g.

hello world
\newpage
```{r, echo=FALSE}
1+1
```
\pagebreak
```{r, echo=FALSE}
plot(1:10)
```

This solution assumes you are knitting PDF. For HTML, you can achieve a similar effect by adding a tag <P style="page-break-before: always">. Note that you likely won't see a page break in your browser (HTMLs don't have pages per se), but the printing layout will have it.

Based on @Stoyan I came up with the following solution:

app.run(function($location, $anchorScroll){
    var uri = window.location.href;

    if(uri.length >= 4){

        var parts = uri.split('#!#');
        if(parts.length > 1){
            var anchor = parts[parts.length -1];
            $location.hash(anchor);
            $anchorScroll();
        }
    }
});

Scripts are raw java embedded in the page code, and if you declare variables in your scripts, then they become local variables embedded in the page.

In contrast, JSTL works entirely with scoped attributes, either at page, request or session scope. You need to rework your scriptlet to fish test out as an attribute:

<c:set var="test" value="test1"/>
<%
  String resp = "abc";
  String test = pageContext.getAttribute("test");
  resp = resp + test;
  pageContext.setAttribute("resp", resp);
%>
<c:out value="${resp}"/>

If you look at the docs for <c:set>, you'll see you can specify scope as page, request or session, and it defaults to page.

Better yet, don't use scriptlets at all: they make the baby jesus cry.

you can configure the coverage exclusion in the sonar properties, outside of the configuration of the jacoco plugin:

...
<properties>
    ....
    <sonar.exclusions>
        **/generated/**/*,
        **/model/**/*
    </sonar.exclusions>
    <sonar.test.exclusions>
        src/test/**/*
    </sonar.test.exclusions>
    ....
    <sonar.java.coveragePlugin>jacoco</sonar.java.coveragePlugin>
    <sonar.jacoco.reportPath>${project.basedir}/../target/jacoco.exec</sonar.jacoco.reportPath>
    <sonar.coverage.exclusions>
        **/generated/**/*,
        **/model/**/*
    </sonar.coverage.exclusions>
    <jacoco.version>0.7.5.201505241946</jacoco.version>
    ....
</properties>
....

and remember to remove the exclusion settings from the plugin

After further reading, and confirmation from Linus G Thiel above, I found I simply had to,

• Downgrade to Node.js 0.6.12
• And either,
  • Install Mocha as global
  • Add ./node_modules/.bin to my PATH

@Jon's :parse/:endparse scheme is a great start, and he has my gratitude for the initial pass, but if you think that the Windows torturous batch system would let you off that easy… well, my friend, you are in for a shock. I have spent the whole day with this devilry, and after much painful research and experimentation I finally managed something viable for a real-life utility.

Let us say that we want to implement a utility foobar. It requires an initial command. It has an optional parameter --foo which takes an optional value (which cannot be another parameter, of course); if the value is missing it defaults to default. It also has an optional parameter --bar which takes a required value. Lastly it can take a flag --baz with no value allowed. Oh, and these parameters can come in any order.

In other words, it looks like this:

foobar <command> [--foo [<fooval>]] [--bar <barval>] [--baz]

Complicated? No, that seems pretty typical of real life utilities. (git anyone?)

Without further ado, here is a solution:

Yes, it really is that bad. See my similar post at https://stackoverflow.com/a/50653047/421049, where I provide more analysis of what is going on in the logic, and why I used certain constructs.

Hideous. Most of that I had to learn today. And it hurt.

I notice many answers just try to increase the amount of memory given to a script which has its place but more often than not it means that something is being too liberal with memory due to an unforseen amount of volume or size. Obviously if your not the author of a script your at the mercy of the author unless your feeling ambitious :) The PHP docs even say memory issues are due to "poorly written scripts"

It should be mentioned that ini_set('memory_limit', '-1'); (no limit) can cause server instability as 0 bytes free = bad things. Instead, find a reasonable balance by what your script is trying to do and the amount of available memory on a machine.

A better approach: If you are the author of the script (or ambitious) you can debug such memory issues with xdebug. The latest version (2.6.0 - released 2018-01-29) brought back memory profiling that shows you what function calls are consuming large amounts of memory. It exposes issues in the script that are otherwise hard to find. Usually, the inefficiencies are in a loop that isn't expecting the volume it's receiving, but each case will be left as an exercise to the reader :)

The xdebug documentation is helpful, but it boils down to 3 steps:

1. Install It - Available through apt-get and yum etc
2. Configure it - xdebug.ini: xdebug.profiler_enable = 1, xdebug.profiler_output_dir = /where/ever/
3. View the profiles in a tool like QCacheGrind, KCacheGrind

try $conn = mysql_connect("localhost", "root") or $conn = mysql_connect("localhost", "root", "")

You can't do

LivingRoom.objects.create(user=instance)

because you have an __init__ method that does NOT take user as argument.

You need something like

#signal function: if a user is created, add control livingroom to the user    
def create_control_livingroom(sender, instance, created, **kwargs):
    if created:
        my_room = LivingRoom()
        my_room.user = instance

Update

But, as bruno has already said it, Django's models.Model subclass's initializer is best left alone, or should accept *args and **kwargs matching the model's meta fields.

So, following better principles, you should probably have something like

class LivingRoom(models.Model):
    '''Living Room object'''
    user = models.OneToOneField(User)

    def __init__(self, *args, temp=65, **kwargs):
        self.temp = temp
        return super().__init__(*args, **kwargs)

Note - If you weren't using temp as a keyword argument, e.g. LivingRoom(65), then you'll have to start doing that. LivingRoom(user=instance, temp=66) or if you want the default (65), simply LivingRoom(user=instance) would do.

You can add "issue time" to token and maintain "last logout time" for each user on the server. When you check token validity, also check "issue time" be after "last logout time".

I can reproduce your problem if there are no files in the directory that were modified in the last hour. In that case, find . -mmin -60 returns nothing. The command find . -mmin -60 |xargs ls -l, however, returns every file in the directory which is consistent with what happens when ls -l is run without an argument.

To make sure that ls -l is only run when a file is found, try:

find . -mmin -60 -type f -exec ls -l {} +

I would suggest using TRUNCATE TABLE, it's quicker and uses less resources than DELETE FROM xxx

Here's the related MSDN article

1. Start the Apache Server and MySQL instances from the XAMPP control panel.
2. Now goto to your localhost.
3. Click on user accounts -> Click on Edit privileges -> You will find an option change password just change password as you want click on go. Image are given below
4. If you refresh the page, you will be getting a error message. This is because the phpMyAdmin configuration file is not aware of our newly set root passoword. To do this we have to modify the phpMyAdmin config file.
5. Open terminal window (not mac default terminal please check attached image)
6. Then Run apt-get update in the newly opened terminal.
7. Then run apt-get install nano this will install nano
8. CD to cd ../opt/lampp/phpmyadmin
9. Open and Edit nano config.inc.php and save.

You should assign an array of char pointers, and then, for each pointer assign enough memory for the string:

char **orderedIds;

orderedIds = malloc(variableNumberOfElements * sizeof(char*));
for (int i = 0; i < variableNumberOfElements; i++)
    orderedIds[i] = malloc((ID_LEN+1) * sizeof(char)); // yeah, I know sizeof(char) is 1, but to make it clear...

Seems like a good way to me. Although you perform many mallocs, you clearly assign memory for a specific string, and you can free one block of memory without freeing the whole "string array"

Marc Gravells answer was right for me but my xsd was with extension of .xml. When I used xsd program it gave :
- The table (Amt) cannot be the child table to itself in nested relations.

As per this KB325695 I renamed extension from .xml to .xsd and it worked fine.

Suppose the dataframe df has 3 columns id1, name1, price1 and you wish to rename them to id2, name2, price2

val list = List("id2", "name2", "price2")
import spark.implicits._
val df2 = df.toDF(list:_*)
df2.columns.foreach(println)

I found this approach useful in many cases.

<script>
       $(document).ready(function () {
           $('select').attr("id", "newId"); //direct descendant of a
       });
</script>

This could do for all purpose. Just add before your body closing tag and don't for get to add Jquery.min.js

Ivo nailed it, but I'll mention that there is one dirty trick you can use, though I don't recommend it if you're going for style points: You can embed JavaScript code directly in your CoffeeScript by escaping it with backticks.

However, here's why this is usually a bad idea: The CoffeeScript compiler is unaware of those variables, which means they won't obey normal CoffeeScript scoping rules. So,

`foo = 'bar'`
foo = 'something else'

compiles to

foo = 'bar';
var foo = 'something else';

and now you've got yourself two foos in different scopes. There's no way to modify the global foo from CoffeeScript code without referencing the global object, as Ivy described.

Of course, this is only a problem if you make an assignment to foo in CoffeeScript—if foo became read-only after being given its initial value (i.e. it's a global constant), then the embedded JavaScript solution approach might be kinda sorta acceptable (though still not recommended).

Well after I edited and researched, I was able to come up with a solution. Hopefully it'll work for everyone

Just change the script tag to:

var html = document.documentElement

var body = document.body

var documentHeight = Math.max(body.scrollHeight, body.offsetHeight, html.scrollHeight, html.clientHeight, html.offsetHeight)

var PageHeight = Math.max(html.clientHeight || 0, window.innerHeight || 0)

function scrollDownTo(to, duration) {
    if (document.body.scrollTop == to) return;
    if ((documentHeight-to) < PageHeight) {
        to = documentHeight - PageHeight;
    }
    var diff = to - window.pageYOffset;
    var scrollStep = Math.PI / (duration / 10);
    var count = 0, currPos; ajaxe = 1
    var start = window.pageYOffset;
    var scrollInterval = setInterval(function(){
        if (window.pageYOffset != to) {
            count = count + 1;
            if (ajaxe > count) {
                clearInterval(scrollInterval)
            }
            currPos = start +  diff * (0.5 - 0.5 * Math.cos(count * scrollStep));
            scroll( 0, currPos)
            ajaxe = count
        }
        else { clearInterval(scrollInterval);}
    },20);
    }

function test (elID) {
    var dest = document.getElementById(elID);
    scrollDownTo((dest.getBoundingClientRect().top + window.pageYOffset), 500);
}

The HTML is still the same:

<div class="header">
    <p class="menu"><a href="#S1" onclick="test('S1'); return false;">S1</a></p>
    <p class="menu"><a href="#S2" onclick="test('S2'); return false;">S2</a></p>
    <p class="menu"><a href="#S3" onclick="test('S3'); return false;">S3</a></p>
    <p class="menu"><a href="#S4" onclick="test('S4'); return false;">S3</a></p>
</div>
<div style="width: 100%;">
    <div id="S1" class="curtain">
    blabla
    </div>
    <div id="S2" class="curtain">

If you still encounter any issues kindly comment

This might be what you are looking for:

<?php

$text = 'This is a Simple text.';

// this echoes "is is a Simple text." because 'i' is matched first
echo strpbrk($text, 'mi');

// this echoes "Simple text." because chars are case sensitive
echo strpbrk($text, 'S');
?>

Is it?

Or maybe this:

<?php
$mystring = 'abc';
$findme   = 'a';
$pos = strpos($mystring, $findme);

// Note our use of ===.  Simply == would not work as expected
// because the position of 'a' was the 0th (first) character.
if ($pos === false) {
    echo "The string '$findme' was not found in the string '$mystring'";
} else {
    echo "The string '$findme' was found in the string '$mystring'";
    echo " and exists at position $pos";
}
?>

Or even this

<?php
$email  = '[email protected]';
$domain = strstr($email, '@');
echo $domain; // prints @example.com

$user = strstr($email, '@', true); // As of PHP 5.3.0
echo $user; // prints name
?>

You can read all about them in the documentation here:

If you're not in an ipython notebook (like the OP), you can also just declare the size when you declare the figure:

Boris Zbarsky (Mozilla), who probably knows more about the innards of Gecko than anyone else, provided at http://lists.w3.org/Archives/Public/public-html/2009Apr/0195.html the pseudocode repeated below to describe what Gecko based browsers do:

if (@type not set or empty) {
   if (@language not set or empty) {
     // Treat as default script language; what this is depends on the
     // content-script-type HTTP header or equivalent META tag
   } else {
     if (@language is one of "javascript", "livescript", "mocha",
                             "javascript1.0", "javascript1.1",
                             "javascript1.2", "javascript1.3",
                             "javascript1.4", "javascript1.5",
                             "javascript1.6", "javascript1.7",
                             "javascript1.8") {
       // Treat as javascript
     } else {
       // Treat as unknown script language; do not execute
     }
   }
} else {
   if (@type is one of "text/javascript", "text/ecmascript",
                       "application/javascript",
                       "application/ecmascript",
                       "application/x-javascript") {
     // Treat as javascript
   } else {
     // Treat as specified (e.g. if pyxpcom is installed and
     // python script is allowed in this context and the type
     // is one that the python runtime claims to handle, use that).
     // If we don't have a runtime for this type, do not execute.
   }
}

This is big endian test from a configure script:

#include <inttypes.h>
int main(int argc, char ** argv){
    volatile uint32_t i=0x01234567;
    // return 0 for big endian, 1 for little endian.
    return (*((uint8_t*)(&i))) == 0x67;
}

You could use the string formatting operator for that:

>>> '%.2f' % 1.234
'1.23'
>>> '%.2f' % 5.0
'5.00'

The result of the operator is a string, so you can store it in a variable, print etc.

Checkbox

You can create your own CheckBox control extending UIButton with Swift:

    let checkedImage = UIImage(named: "ic_check_box")! as UIImage
    let uncheckedImage = UIImage(named: "ic_check_box_outline_blank")! as UIImage
    
    // Bool property
    var isChecked: Bool = false {
        didSet {
            if isChecked == true {
                self.setImage(checkedImage, for: UIControl.State.normal)
            } else {
                self.setImage(uncheckedImage, for: UIControl.State.normal)
            }
        }
    }
        
    override func awakeFromNib() {
        self.addTarget(self, action:#selector(buttonClicked(sender:)), for: UIControl.Event.touchUpInside)
        self.isChecked = false
    }
        
    @objc func buttonClicked(sender: UIButton) {
        if sender == self {
            isChecked = !isChecked
        }
    }
}

And then add it to your views with Interface Builder:

Radio Buttons

Radio Buttons can be solved in a similar way.

For example, the classic gender selection Woman - Man:

import UIKit

class RadioButton: UIButton {
    var alternateButton:Array<RadioButton>?
    
    override func awakeFromNib() {
        self.layer.cornerRadius = 5
        self.layer.borderWidth = 2.0
        self.layer.masksToBounds = true
    }
    
    func unselectAlternateButtons() {
        if alternateButton != nil {
            self.isSelected = true
            
            for aButton:RadioButton in alternateButton! {
                aButton.isSelected = false
            }
        } else {
            toggleButton()
        }
    }
    
    override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
        unselectAlternateButtons()
        super.touchesBegan(touches, with: event)
    }
    
    func toggleButton() {
        self.isSelected = !isSelected
    }
    
    override var isSelected: Bool {
        didSet {
            if isSelected {
                self.layer.borderColor = Color.turquoise.cgColor
            } else {
                self.layer.borderColor = Color.grey_99.cgColor
            }
        }
    }
}

You can init your radio buttons like this:

    override func awakeFromNib() {
        self.view.layoutIfNeeded()
        
        womanRadioButton.selected = true
        manRadioButton.selected = false
    }
    
    override func viewDidLoad() {
        womanRadioButton?.alternateButton = [manRadioButton!]
        manRadioButton?.alternateButton = [womanRadioButton!]
    }

Hope it helps.

This will work fine with Linq to Objects. However, some LINQ providers have difficulty running CLR methods as part of the query. This is expecially true of some database providers.

The problem is that the DB providers try to move and compile the LINQ query as a database query, to prevent pulling all of the objects across the wire. This is a good thing, but does occasionally restrict the flexibility in your predicates.

Unfortunately, without checking the provider documentation, it's difficult to always know exactly what will or will not be supported directly in the provider. It looks like your provider allows comparisons, but not the string check. I'd guess that, in your case, this is probably about as good of an approach as you can get. (It's really not that different from the IsNullOrEmpty check, other than creating the "string.Empty" instance for comparison, but that's minor.)

Just return true instead?

The return value from the onClick code is what determines whether the link's inherent clicked action is processed or not - returning false means that it isn't processed, but if you return true then the browser will proceed to process it after your function returns and go to the proper anchor.

It is actually a bit simpler than restoring to the same server. Basically, you just walk through the "Restore Database" options. Here is a tutorial for you:

http://www.techrepublic.com/blog/window-on-windows/how-do-i-restore-a-sql-server-database-to-a-new-server/454

Especially since this is a non-production restore, you can feel comfortable just trying it out without worrying about the details too much. Just put your SQL files where you want them on your new server and give it whatever name you want and you are good to go.

I had this problem, except the type it couldn't load was System.Reflection.AssemblyMetadataAttribute. The web application was built on a machine with .NET 4.5 installed (runs fine there), with 4.0 as the target framework, but the error presented itself when it was run on a web server with only 4.0 installed. I then tried it on a web server with 4.5 installed and there was no error. So, as others have said, this is all due to the screwy way Microsoft released 4.5, which basically is an upgrade to (and overwrite of) version 4.0. The System.Reflection assembly references a type that doesn't exist in 4.0 (AssemblyMetadataAttribute) so it will fail if you don't have the new System.Reflection.dll.

You can either install .NET 4.5 on the target web server, or build the application on a machine that does not have 4.5 installed. Far from an ideal resolution.

Got stuck with this issue myself and found one more cause for this problem. If you don't have setter methods in your backing bean for the properties used in your *.xhtml , then the action is simply not invoked.

We always used to use the Jet.OLEDB driver, until we started going to 64 bit applications. Microsoft has not and will not release a 64 bit Jet driver. Here's a simple solution we came up with that uses File.ReadAllLines and String.Split to read and parse the CSV file and manually load a DataTable. As noted above, it DOES NOT handle the situation where one of the column values contains a comma. We use this mostly for reading custom configuration files - the nice part about using CSV files is that we can edit them in Excel.

string CSVFilePathName = @"C:\test.csv";
string[] Lines = File.ReadAllLines(CSVFilePathName);
string[] Fields;
Fields = Lines[0].Split(new char[] { ',' });
int Cols = Fields.GetLength(0);
DataTable dt = new DataTable();
//1st row must be column names; force lower case to ensure matching later on.
for (int i = 0; i < Cols; i++)
    dt.Columns.Add(Fields[i].ToLower(), typeof(string));
DataRow Row;
for (int i = 1; i < Lines.GetLength(0); i++)
{
    Fields = Lines[i].Split(new char[] { ',' });
    Row = dt.NewRow();
    for (int f = 0; f < Cols; f++)
        Row[f] = Fields[f];
    dt.Rows.Add(Row);
}

Add to top of the code,

#!/usr/bin/python

Then, run the following command on the terminal,

chmod +x yourScriptFile

not a good way but kind of quick fix, take a bool to check if in whole list there is any duplicate entry.

bool containsKey;
string newKey;

public void addKey(string newKey)
{
    foreach (string key in MyKeys)
    {
        if (key == newKey)
        {
            containsKey = true;
        }
    }

    if (!containsKey)
    {
        MyKeys.add(newKey);
    }
    else
    {
        containsKey = false;
    }
}

OK, i just fixed this error.

This happens when there is an error in query or table doesn't exist.

Try debugging the query buy running it directly on phpmyadmin to confirm the validity of the mysql Query

You can also call any controller from JavaScript/jQuery. Say you have a controller returning 404 or some other usercontrol/page. Then, on some action, from your client code, you can call some address that will fire your controller and return the result in HTML format your client code can take this returned result and put it wherever you want in you your page...

For Swift 3.0+

extension String {
    func SizeOf_String( font: UIFont) -> CGSize {
        let fontAttribute = [NSFontAttributeName: font]
        let size = self.size(attributes: fontAttribute)  // for Single Line
       return size;
   }
}

Use it like...

        let Str = "ABCDEF"
        let Font =  UIFont.systemFontOfSize(19.0)
        let SizeOfString = Str.SizeOfString(font: Font!)

So, youtube gives out the iframe tag as follows:

<iframe width="560" height="315" src="https://www.youtube.com/embed/2EIeUlvHAiM" frameborder="0" allowfullscreen></iframe>

In my case, i just changed it to width="100%" and left the rest as is. It's not the most elegant solution (after all, in different devices you'll get weird ratios) But the video itself does not get deformed, just the frame.

I was also getting this issue also however none of the above worked for me as I was using a custom binding (for BinaryXML) after an long time digging I found the answer here :-

Sending large XML from Silverlight to WCF

As am using a customBinding, the maxReceivedMessageSize has to be set on the httpTransport element under the binding element in the web.config:

<httpsTransport maxReceivedMessageSize="4194304" /> 

You should use 'tag_name' outside of quotes; then its interpreted as a field of the record. Concatenate using '||' with the literal percent signs:

SELECT id FROM TAG_TABLE WHERE 'aaaaaaaa' LIKE '%' || tag_name || '%';

public void onRestart() {
    super.onRestart();
    Intent intent=new Intent();
    intent.setClass(act, act.getClass());

Your question is already answered here :

• Why do we use rt.jar file in java project ?

Basically, rt.jar contains all of the compiled class files for the base Java Runtime ("rt") Environment. Normally, javac should know the path to this file

Also, a good link on what happens if we try to include our class file in rt.jar.

Here's one more alternative:

var classElements = document.getElementsByClassName("className");

function setClassHeight (classElements, desiredHeightValue) 
    {
        var arrayElements = Object.entries(classElements);
        for(var i = 0; i< arrayElements.length; i++) {
            arrayElements[i][1].style.height = desiredHeightValue;
        }

    }

You can do either…

$qb->where('e.fecha BETWEEN :monday AND :sunday')
   ->setParameter('monday', $monday->format('Y-m-d'))
   ->setParameter('sunday', $sunday->format('Y-m-d'));

or…

$qb->where('e.fecha > :monday')
   ->andWhere('e.fecha < :sunday')
   ->setParameter('monday', $monday->format('Y-m-d'))
   ->setParameter('sunday', $sunday->format('Y-m-d'));

I've found a definition that says that Layers are a logical separation and tiers are a physical separation.

I know this is a seriously old post - but my answer might be useful to others anyway, so here goes. I found that if my CSS style definition for the contenteditable div has a min-height of 200 instead of a height of 200 , then the div scales automatically.

integer & 0xFF

for the first byte

(integer >> 8) & 0xFF

for the second and loop etc., writing into a preallocated byte array. A bit messy, unfortunately.

1. First Remove the adbkey and adbkey.pub from the .android directory in your Home directory.

2. Make .android directory in your home with 710 permissions: $ chmod 710 .android/ and ownership as: chown -R <user>:<user> .android/. Ex:

   $ chmod 710 .android/
   $ chown -R ashan:ashan .android/
   

3. Go to developer options in your mobile and tap option Revoke USB debugging authorizations

4. Turn off all USB Debugging and Developer Options in the device and disconnect the device from your machine.

5. Connect the device again and at first turn on the Developer Options. Then Turn on the USB debugging.

6. At this point in your mobile, you will get a prompt for asking permission from you. Note: you must check the checkbox always accept from this …. option and click ok.

7. Now in you machine, start the adb server: adb start-server.

8. Hopefully when you issue the command: adb devices now, you will see your device ready authorized.

You can use plain javascript, this will call your_func once, after 5 seconds:

setTimeout(function() { your_func(); }, 5000);

If your function has no parameters and no explicit receiver you can call directly setTimeout(func, 5000)

There is also a plugin I've used once. It has oneTime and everyTime methods.

• jQuery timers plugin

Recently I had to retrieve all videos from a channel, and according to YouTube developer documentation: https://developers.google.com/youtube/v3/docs/playlistItems/list

function playlistItemsListByPlaylistId($service, $part, $params) {
    $params = array_filter($params);
    $response = $service->playlistItems->listPlaylistItems(
        $part,
        $params
    );

    print_r($response);
}

playlistItemsListByPlaylistId($service,
    'snippet,contentDetails',
    array('maxResults' => 25, 'playlistId' => 'id of "uploads" playlist'));

Where $service is your Google_Service_YouTube object.

So you have to fetch information from the channel to retrieve the "uploads" playlist that actually has all the videos uploaded by the channel: https://developers.google.com/youtube/v3/docs/channels/list

If new with this API, I highly recommend to turn the code sample from the default snippet to the full sample.

So the basic code to retrieve all videos from a channel can be:

class YouTube
{
    const       DEV_KEY = 'YOUR_DEVELOPPER_KEY';
    private     $client;
    private     $youtube;
    private     $lastChannel;

    public function __construct()
    {
        $this->client = new Google_Client();
        $this->client->setDeveloperKey(self::DEV_KEY);
        $this->youtube = new Google_Service_YouTube($this->client);
        $this->lastChannel = false;
    }

    public function getChannelInfoFromName($channel_name)
    {
        if ($this->lastChannel && $this->lastChannel['modelData']['items'][0]['snippet']['title'] == $channel_name)
        {
            return $this->lastChannel;
        }
        $this->lastChannel = $this->youtube->channels->listChannels('snippet, contentDetails, statistics', array(
            'forUsername' => $channel_name,
        ));
        return ($this->lastChannel);
    }

    public function getVideosFromChannelName($channel_name, $max_result = 5)
    {
        $this->getChannelInfoFromName($channel_name);
        $params = [
            'playlistId' => $this->lastChannel['modelData']['items'][0]['contentDetails']['relatedPlaylists']['uploads'],
            'maxResults'=> $max_result,
        ];
        return ($this->youtube->playlistItems->listPlaylistItems('snippet,contentDetails', $params));
    }
}

$yt = new YouTube();
echo '<pre>' . print_r($yt->getVideosFromChannelName('CHANNEL_NAME'), true) . '</pre>';

Yes, people use these terms interchangeably with regard to MySQL. Though oftentimes you will hear people inappropriately refer to the entire database server as the database.

jQuery's attr method returns the value of the attribute:

The .attr() method gets the attribute value for only the first element in the matched set. To get the value for each element individually, use a looping construct such as jQuery's .each() or .map() method.

All you need is:

$('html').attr('lang') == 'fr-FR'

However, you might want to do a case-insensitive match:

$('html').attr('lang').toLowerCase() === 'fr-fr'

jQuery's val method returns the value of a form element.

The .val() method is primarily used to get the values of form elements such as input, select and textarea. In the case of <select multiple="multiple"> elements, the .val() method returns an array containing each selected option; if no option is selected, it returns null.

I could not get IE8+ to work by adding a jQuery event handler to the file input type. I had to go old-school and add the the onchange="" attribute to the input tag:

<input type='file' onchange='getFilename(this)'/>

function getFileName(elm) {
   var fn = $(elm).val();
   ....
}

EDIT:

function getFileName(elm) {
   var fn = $(elm).val();
   var filename = fn.match(/[^\\/]*$/)[0]; // remove C:\fakename
   alert(filename);
}

You could use hashname.key(valuename)

Or, an inversion may be in order. new_hash = hashname.invert will give you a new_hash that lets you do things more traditionally.

                 temp = a[index];
                 a[index] = a[j];
                 a[j] = temp;

    System.out.print("Output is:- ");
    for(int i=0;i<a.length;i++)
    {
        System.out.println(a[i]);
    }

}
}

I recommend using any of these two commands.

git branch | grep -e "^*" | cut -d' ' -f 2

OR

git status | sed -n 1p | cut -d' ' -f 3

OR (more verbose)

git status -uno -bs| cut -d'#' -f 3 | cut -d . -f 1| sed -e 's/^[ \t]//1'| sed -n 1p

I wasn't quite sure where I would store the start position, so I want to elaborate on David Boikes comment. I found that I could store that variable in the ui.item object itself and retrieve it in the stop function as so:

$( "#sortable" ).sortable({
    start: function(event, ui) {
        ui.item.startPos = ui.item.index();
    },
    stop: function(event, ui) {
        console.log("Start position: " + ui.item.startPos);
        console.log("New position: " + ui.item.index());
    }
});

There are many ways to debug JavaScript code. Following two approaches are widely used to debug JavaScript via code

1. Using console.log() to print out the values in the browser console. (This will help you understand the values at certain points of your code)

2. Debugger keyword. Add debugger; to the locations you want to debug, and open the browser's developer console and navigate to the sources tab.

For more tools and ways in which you debug JavaScript Code, are given in this link by W3School.

List_of_list =[([z for z in range(x-2,x+1) if z >= 0],y) for y in range(10) for x in range(10)]

This should do the trick. And the output is this:

[([0], 0), ([0, 1], 0), ([0, 1, 2], 0), ([1, 2, 3], 0), ([2, 3, 4], 0),  ([3, 4, 5], 0), ([4, 5, 6], 0), ([5, 6, 7], 0), ([6, 7, 8], 0), ([7, 8, 9], 0), ([0], 1), ([0, 1], 1), ([0, 1, 2], 1), ([1, 2, 3], 1), ([2, 3, 4], 1), ([3, 4, 5], 1), ([4, 5, 6], 1), ([5, 6, 7], 1), ([6, 7, 8], 1), ([7, 8, 9], 1), ([0], 2), ([0, 1], 2), ([0, 1, 2], 2), ([1, 2, 3], 2), ([2, 3, 4], 2), ([3, 4, 5], 2), ([4, 5, 6], 2), ([5, 6, 7], 2), ([6, 7, 8], 2), ([7, 8, 9], 2), ([0], 3), ([0, 1], 3), ([0, 1, 2], 3), ([1, 2, 3], 3), ([2, 3, 4], 3), ([3, 4, 5], 3), ([4, 5, 6], 3), ([5, 6, 7], 3), ([6, 7, 8], 3), ([7, 8, 9], 3), ([0], 4), ([0, 1], 4), ([0, 1, 2], 4), ([1, 2, 3], 4), ([2, 3, 4], 4), ([3, 4, 5], 4), ([4, 5, 6], 4), ([5, 6, 7], 4), ([6, 7, 8], 4), ([7, 8, 9], 4), ([0], 5), ([0, 1], 5), ([0, 1, 2], 5), ([1, 2, 3], 5), ([2, 3, 4], 5), ([3, 4, 5], 5), ([4, 5, 6], 5), ([5, 6, 7], 5), ([6, 7, 8], 5), ([7, 8, 9], 5), ([0], 6), ([0, 1], 6), ([0, 1, 2], 6), ([1, 2, 3], 6), ([2, 3, 4], 6), ([3, 4, 5], 6), ([4, 5, 6], 6), ([5, 6, 7], 6), ([6, 7, 8], 6), ([7, 8, 9], 6), ([0], 7), ([0, 1], 7), ([0, 1, 2], 7), ([1, 2, 3], 7), ([2, 3, 4], 7), ([3, 4, 5], 7), ([4, 5, 6], 7), ([5, 6, 7], 7), ([6, 7, 8], 7), ([7, 8, 9], 7), ([0], 8), ([0, 1], 8), ([0, 1, 2], 8), ([1, 2, 3], 8), ([2, 3, 4], 8), ([3, 4, 5], 8), ([4, 5, 6], 8), ([5, 6, 7], 8), ([6, 7, 8], 8), ([7, 8, 9], 8), ([0], 9), ([0, 1], 9), ([0, 1, 2], 9), ([1, 2, 3], 9), ([2, 3, 4], 9), ([3, 4, 5], 9), ([4, 5, 6], 9), ([5, 6, 7], 9), ([6, 7, 8], 9), ([7, 8, 9], 9)]    

This is done by list comprehension(which makes looping elements in a list via one line code possible). The logic behind this one-line code is the following:

(1) for x in range(10) and for y in range(10) are employed for two independent loops inside a list

(2) (a list, y) is the general term of the loop, which is why it is placed before two for's in (1)

(3) the length of the list in (2) cannot exceed 3, and the list depends on x, so

[z for z in range(x-2,x+1)] 

is used

(4) because z starts from zero but range(x-2,x+1) starts from -2 which isn't what we want, so a conditional statement if z >= 0 is placed at the end of the list in (2)

[z for z in range(x-2,x+1) if z >= 0] 

If you have two buttons and have the same id call to your button click events like this:

Button btn1;
Button btn2;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    btn1= (Button)findViewById(R.id.button1);

    btn1.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Intent intent=new Intent(MainActivity.this,target.class);
            startActivity(intent);
        }
    });

    btn2=(Button) findViewById(R.id.button1);//Have same id call previous button---> button1

    btn2.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {

        }
    });

When you clicked button1, button2 will work and you cannot open your second activity.

Try invoking your command with Invoke-Expression:

Invoke-Expression $cmd1

Here is a working example on my machine:

$cmd = "& 'C:\Program Files\7-zip\7z.exe' a -tzip c:\temp\test.zip c:\temp\test.txt"
Invoke-Expression $cmd

iex is an alias for Invoke-Expression so you could do:

iex $cmd1

Good Luck...

If unspecified, the sum is computed by adding the layout_weight of all of the children. This can be used for instance to give a single child 50% of the total available space by giving it a layout_weight of 0.5 and setting the weightSum to 1.0. Must be a floating point value, such as "1.2"

    <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:id="@+id/main_rel"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="horizontal"
        android:weightSum="2.0" >

        <RelativeLayout
            android:id="@+id/child_one"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:layout_weight="1.0"

You need to move your angular app code below the inclusion of the angular libraries. At the time your angular code runs, angular does not exist yet. This is an error (see your dev tools console).

In this line:

var app = angular.module(`

you are attempting to access a variable called angular. Consider what causes that variable to exist. That is found in the angular.js script which must then be included first.

  <h1>{{2+3}}</h1>

  <!-- In production use:
  <script src="//ajax.googleapis.com/ajax/libs/angularjs/1.0.7/angular.min.js"></script>
  -->
  <script src="lib/angular/angular.js"></script>
  <script src="lib/angular/angular-route.js"></script>
  <script src="js/app.js"></script>
  <script src="js/services.js"></script>
  <script src="js/controllers.js"></script>
  <script src="js/filters.js"></script>
  <script src="js/directives.js"></script>

      <script>
        var app = angular.module('myApp',[]);

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

            return function(scope, element,attrs) {
                element.bind('click',function() {alert('click')});
            };

        });
    </script>

For completeness, it is true that your directive is similar to the already existing directive ng-click, but I believe the point of this exercise is just to practice writing simple directives, so that makes sense.

Do, I need to resolve all the conflicts before proceeding to next cherry -pick

Yes, at least with the standard git setup. You cannot cherry-pick while there are conflicts.

Furthermore, in general conflicts get harder to resolve the more you have, so it's generally better to resolve them one by one.

That said, you can cherry-pick multiple commits at once, which would do what you are asking for. See e.g. How to cherry-pick multiple commits . This is useful if for example some commits undo earlier commits. Then you'd want to cherry-pick all in one go, so you don't have to resolve conflicts for changes that are undone by later commits.

Further, is it suggested to do cherry-pick or branch merge in this case?

Generally, if you want to keep a feature branch up to date with main development, you just merge master -> feature branch. The main advantage is that a later merge feature branch -> master will be much less painful.

Cherry-picking is only useful if you must exclude some changes in master from your feature branch. Still, this will be painful so I'd try to avoid it.

Try this it will work --

if($('#EventStartTimeMin').val() === " ") {

    alert("Please enter start time!");

}

With multiple conditions

<div ng-class="{'class1' : con1 || can2, 'class2' : con3 && con4}">
Hello World!
</div>

For documentation purpose, it's better to list the string values that are legal:

size: PropTypes.oneOfType([
    PropTypes.number,
    PropTypes.oneOf([ 'SMALL', 'LARGE' ]),
]),

You don't have to include String twice, and you don't have to use New.
Either of the following will work...

Dim strings() as String = {}
Dim strings as String() = {}

As pointed out in comments and other answers, the ISO C++ standard library did not add round() until ISO C++11, when this function was pulled in by reference to the ISO C99 standard math library.

For positive operands in [½, ub] round(x) == floor (x + 0.5), where ub is 2²³ for float when mapped to IEEE-754 (2008) binary32, and 2⁵² for double when it is mapped to IEEE-754 (2008) binary64. The numbers 23 and 52 correspond to the number of stored mantissa bits in these two floating-point formats. For positive operands in [+0, ½) round(x) == 0, and for positive operands in (ub, +8] round(x) == x. As the function is symmetric about the x-axis, negative arguments x can be handled according to round(-x) == -round(x).

This leads to the compact code below. It compiles into a reasonable number of machine instructions across various platforms. I observed the most compact code on GPUs, where my_roundf() requires about a dozen instructions. Depending on processor architecture and toolchain, this floating-point based approach could be either faster or slower than the integer-based implementation from newlib referenced in a different answer.

I tested my_roundf() exhaustively against the newlib roundf() implementation using Intel compiler version 13, with both /fp:strict and /fp:fast. I also checked that the newlib version matches the roundf() in the mathimf library of the Intel compiler. Exhaustive testing is not possible for double-precision round(), however the code is structurally identical to the single-precision implementation.

Using river can present issues when your operation scales up. River will use a ton of memory when under heavy operation. I recommend implementing your own elasticsearch models, or if you're using mongoose you can build your elasticsearch models right into that or use mongoosastic which essentially does this for you.

Another disadvantage to Mongodb River is that you'll be stuck using mongodb 2.4.x branch, and ElasticSearch 0.90.x. You'll start to find that you're missing out on a lot of really nice features, and the mongodb river project just doesn't produce a usable product fast enough to keep stable. That said Mongodb River is definitely not something I'd go into production with. It's posed more problems than its worth. It will randomly drop write under heavy load, it will consume lots of memory, and there's no setting to cap that. Additionally, river doesn't update in realtime, it reads oplogs from mongodb, and this can delay updates for as long as 5 minutes in my experience.

We recently had to rewrite a large portion of our project, because its a weekly occurrence that something goes wrong with ElasticSearch. We had even gone as far as to hire a Dev Ops consultant, who also agrees that its best to move away from River.

UPDATE: Elasticsearch-mongodb-river now supports ES v1.4.0 and mongodb v2.6.x. However, you'll still likely run into performance problems on heavy insert/update operations as this plugin will try to read mongodb's oplogs to sync. If there are a lot of operations since the lock(or latch rather) unlocks, you'll notice extremely high memory usage on your elasticsearch server. If you plan on having a large operation, river is not a good option. The developers of ElasticSearch still recommend you to manage your own indexes by communicating directly with their API using the client library for your language, rather than using river. This isn't really the purpose of river. Twitter-river is a great example of how river should be used. Its essentially a great way to source data from outside sources, but not very reliable for high traffic or internal use.

Also consider that mongodb-river falls behind in version, as its not maintained by ElasticSearch Organization, its maintained by a thirdparty. Development was stuck on v0.90 branch for a long time after the release of v1.0, and when a version for v1.0 was released it wasn't stable until elasticsearch released v1.3.0. Mongodb versions also fall behind. You may find yourself in a tight spot when you're looking to move to a later version of each, especially with ElasticSearch under such heavy development, with many very anticipated features on the way. Staying up on the latest ElasticSearch has been very important as we rely heavily on constantly improving our search functionality as its a core part of our product.

All in all you'll likely get a better product if you do it yourself. Its not that difficult. Its just another database to manage in your code, and it can easily be dropped in to your existing models without major refactoring.

Agree with TonyM and BBoy - this is the correct answer for original 4*6 printing of label. (args.PageBounds). This worked for me for printing Endicia API service shipping Labels.

private void SubmitResponseToPrinter(ILabelRequestResponse response)
    {
        PrintDocument pd = new PrintDocument();
        pd.PrintPage += (sender, args) =>
        {
            Image i = Image.FromFile(response.Labels[0].FullPathFileName.Trim());
            args.Graphics.DrawImage(i, args.PageBounds);
        };
        pd.Print();
    }

Have you considered iframes or segregating your content and using a simple show/hide?

Edit If you want to use an iframe, you can have the contents of page1 and page2 in one html file. Then you can decide what to show or hide by reading the location.search property of the iframe. So your code can be like this :

For Page 1 : iframe.src = "mypage.html?show=1"

For Page 2 : iframe.src = "mypage.html?show=2"

Now, when your iframe loads, you can use the location.search.split("=")[1], to get the value of the page number and show the contents accordingly. This is just to show that iframes can also be used but the usage is more complex than the normal show/hide using div structures.

No, that's a C++ language feature.

It is a duplicate of this question, with an answer that contains a time measurement of the different methods.

Conclusion: Use [void] or > $null.

Thanks for the input. I'm obviously seeing some issues that aren't being replicated on others machines. Based on Jean's answer I have come up with less elegant solution that seems to work.

Since if I pass the cell a value directly from cdate, or just format it as a number it leaves the cell value as a string I've had to pass the date value into a numerical variable before passing that number back to the cell.

Function CellContentCanBeInterpretedAsADate(cell As Range) As Boolean
    Dim d As Date
    On Error Resume Next
    d = CDate(cell.Value)
    If Err.Number <> 0 Then
        CellContentCanBeInterpretedAsADate = False
    Else
        CellContentCanBeInterpretedAsADate = True
    End If
    On Error GoTo 0
End Function

Example usage:

Dim cell As Range
dim cvalue as double
Set cell = Range("A1")

If CellContentCanBeInterpretedAsADate(cell) Then
    cvalue = cdate(cell.value)
    cell.value = cvalue
    cell.NumberFormat = "mm/dd/yyyy hh:mm"
Else
    cell.NumberFormat = "General"
End If

Just want to add one more way. Found it elsewhere, and is quite simple. Say I want to pass yes for all the prompts at command line for a command "execute_command", Then I would simply pipe yes to it.

yes | execute_command

This will use yes as the answer to all yes/no prompts.

For length including white-space:

$("#id").val().length

For length without white-space:

$("#id").val().replace(/ /g,'').length

For removing only beginning and trailing white-space:

$.trim($("#test").val()).length

For example, the string " t e s t " would evaluate as:

//" t e s t "
$("#id").val(); 

//Example 1
$("#id").val().length; //Returns 9
//Example 2
$("#id").val().replace(/ /g,'').length; //Returns 4
//Example 3
$.trim($("#test").val()).length; //Returns 7

Here is a demo using all of them.

For VB aficionados:

EnumStringValue = System.Enum.GetName(GetType(MyEnum), MyEnumValue)

Ran into the same thing trying to install brew's python3 under Mac OS! The issue here is that in Mac OS, homebrew puts the "real" python a whole layer deeper than you think. You would think from the homebrew output that

$ echo $PYTHONHOME
/usr/local/Cellar/python3/3.6.2/
$ echo $PYTHONPATH
/usr/local/Cellar/python3/3.6.2/bin

would be correct, but invoking $PYTHONPATH/python3 immediately crashes with the abort 6 "can't find encodings." This is because although that $PYTHONHOME looks like a complete installation, having a bin, lib etc, it is NOT the actual Python, which is in a Mac OS "Framework". Do this:

PYTHONHOME=/usr/local/Cellar/python3/3.x.y/Frameworks/Python.framework/Versions/3.x
PYTHONPATH=$PYTHONHOME/bin

(substituting version numbers as appropriate) and it will work fine.

Fixing pip

For this error:

~/Library/Python/2.7/bin/pip: /usr/local/opt/python/bin/python2.7: bad interpreter: No such file or directory`

The source of this problem is a bad python path hardcoded in pip (which means it won't be fixed by e.g. changing your $PATH). That path is no longer hardcoded in the lastest version of pip, so a solution which should work is:

pip install --upgrade pip

But of course, this command uses pip, so it fails with the same error.

The way to bootstrap yourself out of this mess:

1. Run which pip
2. Open that file in a text editor
3. Change the first line from #!/usr/local/opt/python/bin/python2.7 to e.g. #!/usr/local/opt/python2/bin/python2.7 (note the python2 in the path), or any path to a working python interpreter on your machine.
4. Now, pip install --upgrade pip (this overwrites your hack and gets pip working at the latest version, where the interpreter issue should be fixed)

Fixing virtualenv

For me, I found this issue by first having the identical issue from virtualenv:

~/Library/Python/2.7/bin/virtualenv: /usr/local/opt/python/bin/python2.7: bad interpreter: No such file or directory`

The solution here is to run

pip uninstall virtualenv
pip install virtualenv

If running that command gives the same error from pip, see above.

Main advantage of <jsp:include /> over <%@ include > is:

<jsp:include /> allows to pass parameters

which is not possible in <%@include file="somefile.jsp" %>

You can easily add multiple classes to divs... So:

<div class="myclass myclass-one"></div>
<div class="myclass myclass-two"></div>
<div class="myclass myclass-three"></div>

Then in the CSS call to the share class to apply the same styles:

.myclass {...}

And you can still use your other classes like this:

.myclass-three {...}

Or if you want to be more specific in the CSS like this:

.myclass.myclass-three {...}

It really is an "it depends" kinda question. Some general points:

• NoSQL is typically good for unstructured/"schemaless" data - usually, you don't need to explicitly define your schema up front and can just include new fields without any ceremony
• NoSQL typically favours a denormalised schema due to no support for JOINs per the RDBMS world. So you would usually have a flattened, denormalized representation of your data.
• Using NoSQL doesn't mean you could lose data. Different DBs have different strategies. e.g. MongoDB - you can essentially choose what level to trade off performance vs potential for data loss - best performance = greater scope for data loss.
• It's often very easy to scale out NoSQL solutions. Adding more nodes to replicate data to is one way to a) offer more scalability and b) offer more protection against data loss if one node goes down. But again, depends on the NoSQL DB/configuration. NoSQL does not necessarily mean "data loss" like you infer.
• IMHO, complex/dynamic queries/reporting are best served from an RDBMS. Often the query functionality for a NoSQL DB is limited.
• It doesn't have to be a 1 or the other choice. My experience has been using RDBMS in conjunction with NoSQL for certain use cases.
• NoSQL DBs often lack the ability to perform atomic operations across multiple "tables".

You really need to look at and understand what the various types of NoSQL stores are, and how they go about providing scalability/data security etc. It's difficult to give an across-the-board answer as they really are all different and tackle things differently.

For MongoDb as an example, check out their Use Cases to see what they suggest as being "well suited" and "less well suited" uses of MongoDb.

Since Python 3.5, you can also use splat * unpacking syntax to unpack a generator expresion:

*(x for x in range(10)),

Another option:

$(el).trigger({type: 'keypress', which: 13, keyCode: 13});

http://api.jquery.com/trigger/

If .val() is not working, I would suggest you to use the .attr() attribute

<script>
  $(function() {
    $("your_button").on("click", function() {
      $("your_textbox").val("your value");
    });
  });
</script>

• In some cases, function pointers are required to use functions that are in a shared library (.DLL or .so). This includes performing stuff across languages, where oftentimes a DLL interface is provided.
• Making compilers
• Making scientific calculators, where you have an array or vector or string map of function pointers?
• Trying to modify video memory directly - making your own graphics package
• Making an API!
• Data structures - node link pointers for special trees you are making

There are Lots of reasons for pointers. Having C name mangling especially is important in DLLs if you want to maintain cross-language compatibility.

You don't need the separate fill item. In fact, it's invalid. You just have to add a solid block to the shape. The subsequent stroke draws on top of the solid:

<shape 
    xmlns:android="http://schemas.android.com/apk/res/android" 
    android:shape="rectangle">

    <corners android:radius="5dp" />
    <solid android:color="@android:color/white" />
    <stroke
        android:width="1dip"
        android:color="@color/bggrey" />
</shape>

You also don't need the layer-list if you only have one shape.

For file types, where the same file can't be opened in a vertical tab group (for example .vb files) you can

• Open 2 different instances of Visual Studio
• Open the same file in each instance
• Resize the IDE windows & place them side by side to achieve your layout.

If you save to disk in one instance though, you'll have to reload the file when you switch to the other. Also if you make edits in both instances, you'll have to resolve on the second save. Visual Studio prompts you in both cases with various options. You'll simplify your life a bit if you edit in only the one instance.

for /f "delims=" %%i in ("%0") do set "curpath=%%~dpi"
echo "%curpath%"

or

echo "%cd%"

The double quotes are needed if the path contains any & characters.

I have something to add to Aladin's answer:

1. Your view controller should conform to UITextFieldDelegate

   class MyViewController: UIViewController, UITextViewDelegate {
   
   }
   

2. Set the delegate of your textfield: To set the delegate, you can control drag from the textfield to your view controller in the storyboard. I think this is preferable to setting it in code

3. Implement the method in your view controller : textField(_:shouldChangeCharactersInRange:replacementString:)

For startswith, you can use indexOf:

if(str.indexOf('Hello') == 0) {

...

ref

and you can do the maths based on string length to determine 'endswith'.

if(str.lastIndexOf('Hello') == str.length - 'Hello'.length) {

this works fine for me

DataTable DT = new DataTable();

DT = DT.AsEnumerable().Select(R =>
{
      R["Campo1"] = valor;
      return (R);
}).ToArray().CopyToDataTable();

As a workaround you can use the fact percent vertical padding and margin are computed from the container width. It's quite a ugly solution and I don't know if you'll be able to use it but well, it works: http://jsfiddle.net/bFWT9/

<!DOCTYPE html>

SSH keys and file permission best practices:

• .ssh directory - 0700 (only by owner)
• private key/.pem file - 0400 (read only by owner)

• public key/.pub file - 0600 (read & write only by owner)

  chmod XXXX file/directory

These are the methods of system.console

• ReadKey() (returns a character): reads only one single character from the standard input stream or command line. Usually used when you're giving options to the user in the console to select from, such as select A, B or C. Another prominent example, Press Y or n to continue.
• ReadLine() (returns a string): or Console.Readline() reads a single line from the standard input stream or the command line. As an example, it can be used to ask the user enter their name or age. It reads all the character till we press enter.
• Read() (returns an int): or Console.Read() reads only one single character from the standard input stream. Similar to ReadKey except that it returns an integer. It returns the next character from the input stream, or returns (-1) if there is no more character to be read.

(There are more system.console methods like write() and writeline() as well which are used to write in command line, behaving similarly as read() and readline() methods)

This was clearly described with examples in the MSDN documentation (links are included above).

You can see the log info in the console view of your IDE if you are not using any log4j properties to generate log file. You can define log4j.properties in your project so that those properties would be used to generate log file. A quick sample is listed below.

# Global logging configuration
log4j.rootLogger=DEBUG, stdout, R

# SQL Map logging configuration...
log4j.logger.com.ibatis=INFO

Here is what worked for me:

    <input type="submit" style="margin-left: 50%">

If you only add margin, without the left part, it will center the submit button into the middle of your entire page, making it difficult to find and rendering your form incomplete for people who don't have the patience to find a submit button lol. margin-left centers it within the same line, so it's not further down your page than you intended. You can also use pixels instead of percentage if you just want to indent the submit button a bit and not all the way halfway across the page.

Here's what worked for me:

console.log(process.mainModule.filename);

That didn't work for me, I used some code parts from web, what I did:

new activity: FullScreenImage with:

package yourpackagename;
import yourpackagename.R;


import android.annotation.SuppressLint;
import android.app.Activity;
import android.graphics.Bitmap;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.ImageView;

public class FullScreenImage  extends Activity {


@SuppressLint("NewApi")



@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    setContentView(R.layout.layout_full);

    Bundle extras = getIntent().getExtras();
    Bitmap bmp = (Bitmap) extras.getParcelable("imagebitmap");

    ImageView imgDisplay;
    Button btnClose;


    imgDisplay = (ImageView) findViewById(R.id.imgDisplay);
    btnClose = (Button) findViewById(R.id.btnClose);


   btnClose.setOnClickListener(new View.OnClickListener() {            
    public void onClick(View v) {
    FullScreenImage.this.finish();
}
});


 imgDisplay.setImageBitmap(bmp );

}   


}

Then create a xml: layout_full

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent" >

<ImageView
    android:id="@+id/imgDisplay"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:scaleType="fitCenter" />

<Button
    android:id="@+id/btnClose"
    android:layout_width="wrap_content"
    android:layout_height="30dp"
    android:layout_alignParentRight="true"
    android:layout_alignParentTop="true"
    android:layout_marginRight="15dp"
    android:layout_marginTop="15dp"
    android:paddingTop="2dp"
    android:paddingBottom="2dp"
    android:textColor="#ffffff"
    android:text="Close" />

   </RelativeLayout>

And finally, send the image name from your mainactivity

   final ImageView im = (ImageView)findViewById(R.id.imageView1) ; 
   im.setBackgroundDrawable(getResources().getDrawable(id1));

   im.setOnClickListener(new OnClickListener() {

      @Override
       public void onClick(View view) {
       Intent intent = new Intent(NAMEOFYOURCURRENTACTIVITY.this, FullScreenImage.class);

       im.buildDrawingCache();
       Bitmap image= im.getDrawingCache();

       Bundle extras = new Bundle();
       extras.putParcelable("imagebitmap", image);
       intent.putExtras(extras);
       startActivity(intent);

                                }
                            });

Method 1:

• type localhost:8080 in your browser to know which process is taking 8080 port
• uninstall that program

Method 2:

re-install the apache tomcat BUT during installation change the port number. Watch carefully the installation process

I'd go with the following:

Select max(start_ts) 
from db 
where trunc(start_ts) =  date'13-may-2016'

Starting with HTML5, <input type="date" /> will do just fine.

Demo: http://jsfiddle.net/8N6KH/

You typically have to do this in a single syscall, or else you will get a race condition.

This will open for reading and writing, creating the file if necessary.

FILE *fp = fopen("scores.dat", "ab+");

If you want to read it and then write a new version from scratch, then do it as two steps.

FILE *fp = fopen("scores.dat", "rb");
if (fp) {
    read_scores(fp);
}

// Later...

// truncates the file
FILE *fp = fopen("scores.dat", "wb");
if (!fp)
    error();
write_scores(fp);

#!/usr/bin/env python
"""Print a field specified by row, column numbers from given csv file.

USAGE:
    %prog csv_filename row_number column_number
"""
import csv
import sys

filename = sys.argv[1]
row_number, column_number = [int(arg, 10)-1 for arg in sys.argv[2:])]

with open(filename, 'rb') as f:
     rows = list(csv.reader(f))
     print rows[row_number][column_number]

Example

$ python print-csv-field.py input.csv 2 2
ddddd

Note: list(csv.reader(f)) loads the whole file in memory. To avoid that you could use itertools:

import itertools
# ...
with open(filename, 'rb') as f:
     row = next(itertools.islice(csv.reader(f), row_number, row_number+1))
     print row[column_number]

It is also possible to pass props as Object or Array. In this case data will be two-way binded:

I prefer this solution, over the accepted answer by Michael Williamson, it catches changes to sources+inline files, then sources+headers, and finally sources only. Advantage here is that the whole library is not recompiled if only a a few changes are made. Not a huge consideration for a project with a couple of files, bur if you have 10 or a 100 sources, you will notice the difference.

Use brackets to group the OR statements.

mysql_query("SELECT * FROM Drinks WHERE email='$Email' AND (date='$Date_Today' OR date='$Date_Yesterday' OR date='$Date_TwoDaysAgo' OR date='$Date_ThreeDaysAgo' OR date='$Date_FourDaysAgo' OR date='$Date_FiveDaysAgo' OR date='$Date_SixDaysAgo' OR date='$Date_SevenDaysAgo')");

You can also use IN

mysql_query("SELECT * FROM Drinks WHERE email='$Email' AND date IN ('$Date_Today','$Date_Yesterday','$Date_TwoDaysAgo','$Date_ThreeDaysAgo','$Date_FourDaysAgo','$Date_FiveDaysAgo','$Date_SixDaysAgo','$Date_SevenDaysAgo')");

The <button> element, when placed in a form, will submit the form automatically unless otherwise specified. You can use the following 2 strategies:

1. Use <button type="button"> to override default submission behavior
2. Use event.preventDefault() in the onSubmit event to prevent form submission

Solution 1:

• Advantage: simple change to markup
• Disadvantage: subverts default form behavior, especially when JS is disabled. What if the user wants to hit "enter" to submit?

Insert extra type attribute to your button markup:

<button id="button" type="button" value="send" class="btn btn-primary">Submit</button>

Solution 2:

• Advantage: form will work even when JS is disabled, and respects standard form UI/UX such that at least one button is used for submission

Prevent default form submission when button is clicked. Note that this is not the ideal solution because you should be in fact listening to the submit event, not the button click event:

$(document).ready(function () {
  // Listen to click event on the submit button
  $('#button').click(function (e) {

    e.preventDefault();

    var name = $("#name").val();
    var email = $("#email").val();

    $.post("process.php", {
      name: name,
      email: email
    }).complete(function() {
        console.log("Success");
      });
  });
});

Better variant:

In this improvement, we listen to the submit event emitted from the <form> element:

$(document).ready(function () {
  // Listen to submit event on the <form> itself!
  $('#main').submit(function (e) {

    e.preventDefault();

    var name = $("#name").val();
    var email = $("#email").val();

    $.post("process.php", {
      name: name,
      email: email
    }).complete(function() {
        console.log("Success");
      });
  });
});

Even better variant: use .serialize() to serialize your form, but remember to add name attributes to your input:

The name attribute is required for .serialize() to work, as per jQuery's documentation:

For a form element's value to be included in the serialized string, the element must have a name attribute.

<input type="text" id="name" name="name" class="form-control mb-2 mr-sm-2 mb-sm-0" id="inlineFormInput" placeholder="Jane Doe">
<input type="text" id="email" name="email" class="form-control" id="inlineFormInputGroup" placeholder="[email protected]">

And then in your JS:

$(document).ready(function () {
  // Listen to submit event on the <form> itself!
  $('#main').submit(function (e) {

    // Prevent form submission which refreshes page
    e.preventDefault();

    // Serialize data
    var formData = $(this).serialize();

    // Make AJAX request
    $.post("process.php", formData).complete(function() {
      console.log("Success");
    });
  });
});

Great question and great idea, but in SQL you'll need to do this:

For data type datetime, something like this-

declare @BeginDate    datetime = '1/1/2016',
        @EndDate      datetime = '12/1/2016'
create table #months (dates datetime)
declare @var datetime = @BeginDate
   while @var < dateadd(MONTH, +1, @EndDate)
   Begin
          insert into #months Values(@var)
          set @var = Dateadd(MONTH, +1, @var)
   end

If all you really want is numbers, do this-

create table #numbas (digit int)
declare @var int = 1        --your starting digit
    while @var <= 12        --your ending digit
    begin
        insert into #numbas Values(@var)
        set @var = @var +1
    end

You should use the following:

       <td><input id="priceInput-{{orderLine.id}}" type="number" [(ngModel)]="orderLine.price"></td>

You will need to add the FormsModule to your app.module in the inputs section as follows:

import { FormsModule } from '@angular/forms';

@NgModule({
  declarations: [
    ...
  ],
  imports: [
    BrowserModule,
    FormsModule
  ],
  ..

The use of the brackets around the ngModel are as follows:

• The [] show that it is taking an input from your TS file. This input should be a public member variable. A one way binding from TS to HTML.

• The () show that it is taking output from your HTML file to a variable in the TS file. A one way binding from HTML to TS.

• The [()] are both (e.g. a two way binding)

See here for more information: https://angular.io/guide/template-syntax

I would also suggest replacing id="priceInput-{{orderLine.id}}" with something like this [id]="getElementId(orderLine)" where getElementId(orderLine) returns the element Id in the TS file and can be used anywere you need to reference the element (to avoid simple bugs like calling it priceInput1 in one place and priceInput-1 in another. (if you still need to access the input by it's Id somewhere else)

Bootstrap 3 has its own class for this called:

hidden-print

It is defined like this:

@media print {
  .hidden-print {
    display: none !important;
  }
}

You do not have to define it on your own.

In Bootstrap 4 this has changed to:

.d-print-none

My way, no Spring, used during a unit test:

URI uri = TestClass.class.getResource("/resources").toURI();
Path myPath = Paths.get(uri);
Stream<Path> walk = Files.walk(myPath, 1);
for (Iterator<Path> it = walk.iterator(); it.hasNext(); ) {
    Path filename = it.next();   
    System.out.println(filename);
}

One option if the number of keys is small is to use chained gets:

value = myDict.get('lastName', myDict.get('firstName', myDict.get('userName')))

But if you have keySet defined, this might be clearer:

value = None
for key in keySet:
    if key in myDict:
        value = myDict[key]
        break

The chained gets do not short-circuit, so all keys will be checked but only one used. If you have enough possible keys that that matters, use the for loop.

No, there's no literal syntax for the empty set. You have to write set().

I had the same problem and the solution was to use my own function instead of json_encode()

echo '["' . implode('","', $row) . '"]';

Use below line of code in the case of Spring Boot Application Add in Spring Boot Main Class @EntityScan(basePackageClasses=YourClassName.class)

Alternatively you can create such a function:

function implode_with_quotes(array $data)
{
    return sprintf("'%s'", implode("', '", $data));
}

For returning multiple column indices, I recommend using the pandas.Index method get_indexer, if you have unique labels:

df = pd.DataFrame({"pear": [1, 2, 3], "apple": [2, 3, 4], "orange": [3, 4, 5]})
df.columns.get_indexer(['pear', 'apple'])
# Out: array([0, 1], dtype=int64)

If you have non-unique labels in the index (columns only support unique labels) get_indexer_for. It takes the same args as get_indeder:

df = pd.DataFrame(
    {"pear": [1, 2, 3], "apple": [2, 3, 4], "orange": [3, 4, 5]}, 
    index=[0, 1, 1])
df.index.get_indexer_for([0, 1])
# Out: array([0, 1, 2], dtype=int64)

Both methods also support non-exact indexing with, f.i. for float values taking the nearest value with a tolerance. If two indices have the same distance to the specified label or are duplicates, the index with the larger index value is selected:

df = pd.DataFrame(
    {"pear": [1, 2, 3], "apple": [2, 3, 4], "orange": [3, 4, 5]},
    index=[0, .9, 1.1])
df.index.get_indexer([0, 1])
# array([ 0, -1], dtype=int64)

Try this..

Dim S As String
S = "RAJAN"
Dim answer As Char
answer = S.Substring(0, 1)

Sample Java application:

I'm crossposting my answer from another question here since it is related and also seems to solve the problem in the question.

Here is my example project with OpenJDK 12, JavaFX 12 and Gradle 5.4

• Opens a JavaFX window with the title "Hello World!"
• Able to build a working runnable distribution zip file (Windows to be tested)
• Able to open and run in IntelliJ without additional configuration
• Able to run from the command line

I hope somebody finds the Github project useful.

Instructions for the Scala case:

Additionally below are instructions that work with the Gradle Scala plugin, but don't seem work with Java. I'm leaving this here in case somebody else is also using Scala, Gradle and JavaFX.

1) As mentioned in the question, the JavaFX Gradle plugin needs to be set up. Open JavaFX has detailed documentation on this

2) Additionally you need the the JavaFX SDK for your platform unzipped somewhere. NOTE: Be sure to scroll down to Latest releases section where JavaFX 12 is (LTS 11 is first for some reason.)

3) Then, in IntelliJ you go to the File -> Project Structure -> Libraries, hit the ?-button and add the lib folder from the unzipped JavaFX SDK.

For longer instructions with screenshots, check out the excellent Open JavaFX docs for IntelliJ I can't get a deep link working, so select JavaFX and IntelliJ and then Modular from IDE from the docs nav. Then scroll down to step 3. Create a library. Consider checking the other steps too if you are having trouble.

It is difficult to say if this is exactly the same situation as in the original question, but it looked similar enough that I landed here, so I'm adding my experience here to help others.

You must use a .ts file - e.g. test.ts to get Typescript validation, intellisense typing of vars, return types, as well as "typed" error checking (e.g. passing a string to a method that expects an number param will error out).

It will be transpiled into (standard) .js via tsc.

Update (11/2018):

Clarification needed based on down-votes, very helpful comments and other answers.

types

• Yes, you can do type checking in VS Code in .js files with @ts-check - as shown in the animation

• What I originally was referring to for Typescript types is something like this in .ts which isn't quite the same thing:

  hello-world.ts

  function hello(str: string): string {
    return 1;
  }
  
  function foo(str:string):void{
     console.log(str);
  }
  

  This will not compile. Error: Type "1" is not assignable to String

• if you tried this syntax in a Javascript hello-world.js file:

  //@ts-check
  
  function hello(str: string): string {
    return 1;
  }
  
  function foo(str:string):void{
     console.log(str);
  }
  

  The error message referenced by OP is shown: [js] 'types' can only be used in a .ts file

If there's something I missed that covers this as well as the OP's context, please add. Let's all learn.

Add the following lines to your ~/.bash_profile or ~/.zshrc file(s).

export LC_CTYPE=C 
export LANG=C

You could profile it, if you really cared. Write a loop of many iterations and see what happens. Chances are, however, that this is not the bottleneck in your application, and TrimStart seems the most semantically correct. Strive to write code readably before optimizing.

Simple:

st =  "abcdefghij"
st = st[:-1]

There is also another way that shows how it is done with steps:

list1 = "abcdefghij"
list2 = list(list1)
print(list2)
list3 = list2[:-1]
print(list3)

This is also a way with user input:

list1 = input ("Enter :")
list2 = list(list1)
print(list2)
list3 = list2[:-1]
print(list3)

To make it take away the last word in a list:

list1 = input("Enter :")
list2 = list1.split()
print(list2)
list3 = list2[:-1]
print(list3)

I'm guessing you've taken a look at mod_perl?

Have you tried the following tutorial?

EDIT: In relation to your posting - perhaps you could include a sample of the code inside your .cgi file. Perhaps even the first few lines?

You can't do this automatically. Your JS can't see the files in the same directory as it.

Easiest is probably to give a list of those image names to your JavaScript.

Otherwise, you might be able to fetch a directory listing from the web server using JS and parse it to get the list of images.

Use -

new Select(driver.findElement(By.id("gender"))).selectByVisibleText("Germany");

Of course, you need to import org.openqa.selenium.support.ui.Select;

Use Apache Commons (IO and Lang) for simple/common things like this.

Imports:

import org.apache.commons.io.FileUtils;
import org.apache.commons.lang3.ArrayUtils;

Code:

String contents = FileUtils.readFileToString(new File("path/to/your/file.txt"));
String[] array = ArrayUtils.toArray(contents.split(" "));

Done.

1. Create the Java code that can receive an argument as a command line argument.

   class TestCode{
       public static void main(String args[]){
           System.out.println("first argument is: "+args[0]);
       }
   }
   

2. Run the program without arguments (press F6).

3. In the Output window, at the bottom, click the double yellow arrow (or the yellow button) to open a Run dialog.

4. If the argument you need to pass is testArgument, then here in this window pass the argument as application.args=testArgument.

This will give the output as follows in the same Output window:

first argument is: testArgument

For Maven, the instructions are similar, but change the exec.args property instead:

exec.args=-classpath %classpath package.ClassName PARAM1 PARAM2 PARAM3

Note: Use single quotes for string parameters that contain spaces.

I think the answer may be easier to understand like this:

$('#empid').on('change',function() {_x000D_
  alert($(this).val());_x000D_
  console.log($(this).val());_x000D_
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.10.0/jquery.min.js"></script>_x000D_
<select id="empid" name="empname" multiple="multiple">_x000D_
  <option value="0">Potato</option>_x000D_
  <option value="1">Carrot</option>_x000D_
  <option value="2">Apple</option>_x000D_
  <option value="3">Raisins</option>_x000D_
  <option value="4">Peanut</option>_x000D_
</select>_x000D_
<br />_x000D_
Hold CTRL / CMD for selecting multiple fields

If you select "Carrot" and "Raisins" in the list, the output will be "1,3".

DateTimeFormatter formatter = DateTimeFormatter.ofPattern("yyyy MM dd");
String text = date.toString(formatter);
LocalDate date = LocalDate.parse(text, formatter);

I believe this might help, you may need to use some sort of localdate variation instead of instant

Open terminal and type "cd < ProjectPath >"

1. Remove existing files: find . -name .DS_Store -print0 | xargs -0 git rm -f --ignore-unmatch

2. nano .gitignore

3. Add this .DS_Store

4. type "ctrl + x"

5. Type "y"

6. Enter to save file

7. git add .gitignore

8. git commit -m '.DS_Store removed.'

"Timeline (responsive)" snippet:

This looks very, very close to what your example shows. The bootstrap snippet linked below covers all the bases you are looking for. I've been considering it myself, with the same requirements you have ( especially responsiveness ). This morphs well between screen sizes and devices.

You can fork this and use it as a great starting point for your specific expectations:

Here are two screenshots I took for you... wide and thin:

Another way to do it is to make an empty section right before the one you want the header on and put your header on that section. Because the section is empty the header will scroll immediately.

When is a github repository not empty, like .gitignore and license

Use pull --allow-unrelated-histories and push --force-with-lease

Use commands

git init
git add .
git commit -m "initial commit"
git remote add origin https://github.com/...
git pull origin master --allow-unrelated-histories
git push --force-with-lease

I found the next command

mvn dependency:copy-dependencies -Dclassifier=sources

here maven.apache.org

Make a div 100% wide and 100% high. Then set a background image.

There's of course the rather obvious:

Data[...,0] + 1j * Data[...,1]

Following SierraX and Peter's suggestion about text manipulation, curly brackets {} are used to pass a variable to a command, for instance:

Let's say you have a sposi.txt file containing the first line of a well-known Italian novel:

> sposi="somewhere/myfolder/sposi.txt"
> cat $sposi

Ouput: quel ramo del lago di como che volge a mezzogiorno

Now create two variables:

# Search the 2nd word found in the file that "sposi" variable points to
> word=$(cat $sposi | cut -d " " -f 2)

# This variable will replace the word
> new_word="filone"

Now substitute the word variable content with the one of new_word, inside sposi.txt file

> sed -i "s/${word}/${new_word}/g" $sposi
> cat $sposi

Ouput: quel filone del lago di como che volge a mezzogiorno

The word "ramo" has been replaced.

it works for me. if you want to enable future time for choose, you have to delete maximum date. You need to to do like followings.

 btnDate.setOnClickListener(new View.OnClickListener() {
                       @Override
                       public void onClick(View v) {
                              DialogFragment newFragment = new DatePickerFragment();
                                    newFragment.show(getSupportFragmentManager(), "datePicker");
                            }
                        });

            public static class DatePickerFragment extends DialogFragment
                        implements DatePickerDialog.OnDateSetListener {

                    @Override
                    public Dialog onCreateDialog(Bundle savedInstanceState) {
                        final Calendar c = Calendar.getInstance();
                        int year = c.get(Calendar.YEAR);
                        int month = c.get(Calendar.MONTH);
                        int day = c.get(Calendar.DAY_OF_MONTH);
                        DatePickerDialog dialog = new DatePickerDialog(getActivity(), this, year, month, day);
                        dialog.getDatePicker().setMaxDate(c.getTimeInMillis());
                        return  dialog;
                    }

                    public void onDateSet(DatePicker view, int year, int month, int day) {
                       btnDate.setText(ConverterDate.ConvertDate(year, month + 1, day));
                    }
                }

Print the stack trace to a PrintStream, then convert it to a String:

// ...

catch (Exception e)
{
    ByteArrayOutputStream out = new ByteArrayOutputStream(); 
    e.printStackTrace(new PrintStream(out));
    String str = new String(out.toByteArray());

    System.out.println(str);
}

If you want to find out only whether or not the files are identical, you can use the Windows fc command in binary mode:

fc.exe /b file1 file2

For details, see the reference for fc

Take a look at Enumerable#each_slice:

foo.each_slice(3).to_a
#=> [["1", "2", "3"], ["4", "5", "6"], ["7", "8", "9"], ["10"]]

Even shorter and with json-functions:

JSONObject songsObject = json.getJSONObject("songs");
JSONArray songsArray = songsObject.toJSONArray(songsObject.names());

Just wanted to mention that the old "make round() with floor()" trick of

round(f) = floor(f+0.5)

can be turned around to make floor() from round()

floor(f) = round(f-0.5)

Although both these rules break around negative numbers, so using it is less than ideal:

def trunc(f, n):
    if f > 0:
        return "%.*f" % (n, (f - 0.5*10**-n))
    elif f == 0:
        return "%.*f" % (n, f)
    elif f < 0:
        return "%.*f" % (n, (f + 0.5*10**-n))

Just for the forgetting-to-dispose problem, try the solution described in this blog post. Here's the essence:

    public void Dispose ()
    {
        // Dispose logic here ...

        // It's a bad error if someone forgets to call Dispose,
        // so in Debug builds, we put a finalizer in to detect
        // the error. If Dispose is called, we suppress the
        // finalizer.
#if DEBUG
        GC.SuppressFinalize(this);
#endif
    }

#if DEBUG
    ~TimedLock()
    {
        // If this finalizer runs, someone somewhere failed to
        // call Dispose, which means we've failed to leave
        // a monitor!
        System.Diagnostics.Debug.Fail("Undisposed lock");
    }
#endif

For the sake def plot_pca(data): will work, it is necessary to replace the lines

data_resc, data_orig = PCA(data)
ax1.plot(data_resc[:, 0], data_resc[:, 1], '.', mfc=clr1, mec=clr1)

with lines

newData, data_resc, data_orig = PCA(data)
ax1.plot(newData[:, 0], newData[:, 1], '.', mfc=clr1, mec=clr1)

While I agree about not adhering blindly to dogmatic rules, does the "lock stealing" scenario seem so eccentric to you? A thread could indeed acquire the lock on your object "externally"(synchronized(theObject) {...}), blocking other threads waiting on synchronized instance methods.

If you don't believe in malicious code, consider that this code could come from third parties (for instance if you develop some sort of application server).

The "accidental" version seems less likely, but as they say, "make something idiot-proof and someone will invent a better idiot".

So I agree with the it-depends-on-what-the-class-does school of thought.

Edit following eljenso's first 3 comments:

I've never experienced the lock stealing problem but here is an imaginary scenario:

Let's say your system is a servlet container, and the object we're considering is the ServletContext implementation. Its getAttribute method must be thread-safe, as context attributes are shared data; so you declare it as synchronized. Let's also imagine that you provide a public hosting service based on your container implementation.

I'm your customer and deploy my "good" servlet on your site. It happens that my code contains a call to getAttribute.

A hacker, disguised as another customer, deploys his malicious servlet on your site. It contains the following code in the init method:

synchronized (this.getServletConfig().getServletContext()) {
   while (true) {}
}

Assuming we share the same servlet context (allowed by the spec as long as the two servlets are on the same virtual host), my call on getAttribute is locked forever. The hacker has achieved a DoS on my servlet.

This attack is not possible if getAttribute is synchronized on a private lock, because 3rd-party code cannot acquire this lock.

I admit that the example is contrived and an oversimplistic view of how a servlet container works, but IMHO it proves the point.

So I would make my design choice based on security consideration: will I have complete control over the code that has access to the instances? What would be the consequence of a thread's holding a lock on an instance indefinitely?

container class has 15px left & right padding, so if you want to remove this padding, use following, because row class has -15px left & right margin.

<div class="container">
  <div class="row">
     <img class='img-responsive' src="#" alt="" />
  </div>
</div>

After a few hours of playing with the Oracle JDK 1.6, I was able to make it work without any code change. The magic is done by Bouncy Castle to handle SSL and allow JDK 1.6 to run with TLSv1.2 by default. In theory, it could also be applied to older Java versions with eventual adjustments.

1. Download the latest Java 1.6 version from the Java Archive Oracle website
2. Uncompress it on your preferred path and set your JAVA_HOME environment variable
3. Update the JDK with the latest Java Cryptography Extension (JCE) Unlimited Strength Jurisdiction Policy Files 6
4. Download the Bounce Castle files bcprov-jdk15to18-165.jar and bctls-jdk15to18-165.jar and copy them into your ${JAVA_HOME}/jre/lib/ext folder
5. Modify the file ${JAVA_HOME}/jre/lib/security/java.security commenting out the providers section and adding some extra lines

    # Original security providers (just comment it)
    # security.provider.1=sun.security.provider.Sun
    # security.provider.2=sun.security.rsa.SunRsaSign
    # security.provider.3=com.sun.net.ssl.internal.ssl.Provider
    # security.provider.4=com.sun.crypto.provider.SunJCE
    # security.provider.5=sun.security.jgss.SunProvider
    # security.provider.6=com.sun.security.sasl.Provider
    # security.provider.7=org.jcp.xml.dsig.internal.dom.XMLDSigRI
    # security.provider.8=sun.security.smartcardio.SunPCSC

    # Add the Bouncy Castle security providers with higher priority
    security.provider.1=org.bouncycastle.jce.provider.BouncyCastleProvider
    security.provider.2=org.bouncycastle.jsse.provider.BouncyCastleJsseProvider
    
    # Original security providers with different priorities
    security.provider.3=sun.security.provider.Sun
    security.provider.4=sun.security.rsa.SunRsaSign
    security.provider.5=com.sun.net.ssl.internal.ssl.Provider
    security.provider.6=com.sun.crypto.provider.SunJCE 
    security.provider.7=sun.security.jgss.SunProvider
    security.provider.8=com.sun.security.sasl.Provider
    security.provider.9=org.jcp.xml.dsig.internal.dom.XMLDSigRI
    security.provider.10=sun.security.smartcardio.SunPCSC

    # Here we are changing the default SSLSocketFactory implementation
    ssl.SocketFactory.provider=org.bouncycastle.jsse.provider.SSLSocketFactoryImpl

Just to make sure it's working let's make a simple Java program to download files from one URL using https.

import java.io.*;
import java.net.*;


public class DownloadWithHttps {

    public static void main(String[] args) {
        try {
            URL url = new URL(args[0]);
            System.out.println("File to Download: " + url);
            String filename = url.getFile();
            File f = new File(filename);
            System.out.println("Output File: " + f.getName());
            BufferedInputStream in = new BufferedInputStream(url.openStream());
            FileOutputStream fileOutputStream = new FileOutputStream(f.getName());
            int bytesRead;
            byte dataBuffer[] = new byte[1024];

            while ((bytesRead = in.read(dataBuffer, 0, 1024)) != -1) {
                fileOutputStream.write(dataBuffer, 0, bytesRead);
            }
            fileOutputStream.close();

        } catch (Exception ex) {
            ex.printStackTrace();
        }

    }
}

Now, just compile the DownloadWithHttps.java program and execute it with your Java 1.6

${JAVA_HOME}/bin/javac DownloadWithHttps.java
${JAVA_HOME}/bin/java DownloadWithHttps https://repo1.maven.org/maven2/org/apache/commons/commons-lang3/3.10/commons-lang3-3.10.jar

Important note for Windows users: This solution was tested in a Linux OS, if you are using Windows, please replace the ${JAVA_HOME} by %JAVA_HOME%.

I would not use .at for performance reasons.

Define a struct:

//#pragma pack(push, 2) //not useful (see comments below)
struct RGB {
    uchar blue;
    uchar green;
    uchar red;  };

And then use it like this on your cv::Mat image:

RGB& rgb = image.ptr<RGB>(y)[x];

image.ptr(y) gives you a pointer to the scanline y. And iterate through the pixels with loops of x and y

As @pcans suggested you can do this overriding dispatchTouchEvent(MotionEvent event) in your activity.

Here we get the touch coordinates and comparing them to view bounds. If touch is performed outside of a view then do something.

@Override
public boolean dispatchTouchEvent(MotionEvent event) {
    if (event.getAction() == MotionEvent.ACTION_DOWN) {
        View yourView = (View) findViewById(R.id.view_id);
        if (yourView != null && yourView.getVisibility() == View.VISIBLE) {
            // touch coordinates
            int touchX = (int) event.getX();
            int touchY = (int) event.getY();
            // get your view coordinates
            final int[] viewLocation = new int[2];
            yourView.getLocationOnScreen(viewLocation);

            // The left coordinate of the view
            int viewX1 = viewLocation[0];
            // The right coordinate of the view
            int viewX2 = viewLocation[0] + yourView.getWidth();
            // The top coordinate of the view
            int viewY1 = viewLocation[1];
            // The bottom coordinate of the view
            int viewY2 = viewLocation[1] + yourView.getHeight();

            if (!((touchX >= viewX1 && touchX <= viewX2) && (touchY >= viewY1 && touchY <= viewY2))) {

                Do what you want...

                // If you don't want allow touch outside (for example, only hide keyboard or dismiss popup) 
                return false;
            }
        }
    }
    return super.dispatchTouchEvent(event);
}

Also it's not necessary to check view existance and visibility if your activity's layout doesn't change during runtime (e.g. you don't add fragments or replace/remove views from the layout). But if you want to close (or do something similiar) custom context menu (like in the Google Play Store when using overflow menu of the item) it's necessary to check view existance. Otherwise you will get a NullPointerException.

How about this?

=IF(ISERROR(MATCH(A1,B:B, 0)), "No Match", INDIRECT(ADDRESS(MATCH(A1,B:B, 0), 3)))

The "3" at the end means for column C.

Add this code where you want to click and load Fragment. I hope it's work for you.

Fragment fragment = new yourfragment();
        FragmentManager fragmentManager = getActivity().getSupportFragmentManager();
        FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
        fragmentTransaction.replace(R.id.fragment_container, fragment);
        fragmentTransaction.addToBackStack(null);
        fragmentTransaction.commit();

Try this :

apply plugin: 'com.android.application'

android {
compileSdkVersion 27
defaultConfig {
    applicationId "com.example.yourpackagename"
    minSdkVersion 15
    targetSdkVersion 27
    versionCode 1
    versionName "1.0"
    testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
}
}

dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation 'com.android.support:appcompat-v7:27.1.1'
implementation 'com.android.support.constraint:constraint-layout:1.1.3'
testImplementation 'junit:junit:4.12'
androidTestImplementation 'com.android.support.test:runner:1.0.2'
androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
}

Less efficient, but simpler-looking:

m0 = re.match("I love (\w+)", statement)
m1 = re.match("Ich liebe (\w+)", statement)
m2 = re.match("Je t'aime (\w+)", statement)
if m0:
  print "He loves",m0.group(1)
elif m1:
  print "Er liebt",m1.group(1)
elif m2:
  print "Il aime",m2.group(1)

The problem with the Perl stuff is the implicit updating of some hidden variable. That's simply hard to achieve in Python because you need to have an assignment statement to actually update any variables.

The version with less repetition (and better efficiency) is this:

pats = [
    ("I love (\w+)", "He Loves {0}" ),
    ("Ich liebe (\w+)", "Er Liebe {0}" ),
    ("Je t'aime (\w+)", "Il aime {0}")
 ]
for p1, p3 in pats:
    m= re.match( p1, statement )
    if m:
        print p3.format( m.group(1) )
        break

A minor variation that some Perl folk prefer:

pats = {
    "I love (\w+)" : "He Loves {0}",
    "Ich liebe (\w+)" : "Er Liebe {0}",
    "Je t'aime (\w+)" : "Il aime {0}",
}
for p1 in pats:
    m= re.match( p1, statement )
    if m:
        print pats[p1].format( m.group(1) )
        break

This is hardly worth mentioning except it does come up sometimes from Perl programmers.

It is possible the other branch you try to pull from is out of synch; so before adding and removing remote try to (if you are trying to pull from master)

git pull origin master

for me that simple call solved those error messages:

• fatal: 'master' does not appear to be a git repository
• fatal: Could not read from remote repository.

When you want to create an external_table, all field's name must be written in UPPERCASE.

Done.

When you want to generate URL from your Business Logic layer, you do not have the flexibility of using ASP.NET Web Form's Page class/ Control's ResolveUrl(..) etc. Moreover, you may need to generate URL from ASP.NET MVC controller too where you not only miss the Web Form's ResolveUrl(..) method, but also you cannot get the Url.Action(..) even though Url.Action takes only Controller name and Action name, not the relative url.

I tried using

var uri = new Uri(absoluteUrl, relativeUrl)

approach, but there is a problem too. If the web application is hosted in IIS virtual directory, where the url of the app is like this : http://localhost/MyWebApplication1/, and the relative url is "/myPage" then the relative url is resolved as "http://localhost/MyPage" which is another problem.

Therefore, in order to overcome such problems, I have written a UrlUtils class which can work from a class library. So, it wont depend on Page class but it depends on ASP.NET MVC. So, if you dont mind adding reference to MVC dll to your class library project then my class will work smoothly. I have tested in IIS virtual directory scenario where the web application url is like this : http://localhost/MyWebApplication/MyPage. I realized that, sometimes we need to make sure that the Absolute url is SSL url or non SSL url. So, I wrote my class library supporting this option. I have restricted this class library so that the relative url can be absolute url or a relative url that starts with '~/'.

Using this library, I can call

string absoluteUrl = UrlUtils.MapUrl("~/Contact");

Returns : http://localhost/Contact when the page url is : http://localhost/Home/About

Returns : http://localhost/MyWebApplication/Contact when the page url is : http://localhost/MyWebApplication/Home/About

  string absoluteUrl = UrlUtils.MapUrl("~/Contact", UrlUtils.UrlMapOptions.AlwaysSSL);

Returns : **https**://localhost/MyWebApplication/Contact when the page url is : http://localhost/MyWebApplication/Home/About

Here is my class Library :

 public class UrlUtils
    {
        public enum UrlMapOptions
        {
            AlwaysNonSSL,
            AlwaysSSL,
            BasedOnCurrentScheme
        }

        public static string MapUrl(string relativeUrl, UrlMapOptions option = UrlMapOptions.BasedOnCurrentScheme)
        {
            if (relativeUrl.StartsWith("http://", StringComparison.OrdinalIgnoreCase) ||
                relativeUrl.StartsWith("https://", StringComparison.OrdinalIgnoreCase))
                return relativeUrl;

            if (!relativeUrl.StartsWith("~/"))
                throw new Exception("The relative url must start with ~/");

            UrlHelper theHelper = new UrlHelper(HttpContext.Current.Request.RequestContext);

            string theAbsoluteUrl = HttpContext.Current.Request.Url.GetLeftPart(UriPartial.Authority) +
                                           theHelper.Content(relativeUrl);

            switch (option)
            {
                case UrlMapOptions.AlwaysNonSSL:
                    {
                        return theAbsoluteUrl.StartsWith("https://", StringComparison.OrdinalIgnoreCase)
                            ? string.Format("http://{0}", theAbsoluteUrl.Remove(0, 8))
                            : theAbsoluteUrl;
                    }
                case UrlMapOptions.AlwaysSSL:

                        return theAbsoluteUrl.StartsWith("https://", StringComparison.OrdinalIgnoreCase)
                            ? theAbsoluteUrl

                    }

            return theAbsoluteUrl;

Here's an alternative way to do the same call. And your type should always be in CAPS, eg. type:"GET" / type:"POST".

$.ajax({
      url:/ControllerName/ActionName,
      data: "id=" + Id + "&param2=" + param2,
      type: "GET",
      success: function(data){
            // code here
      },
      error: function(passParams){
           // code here
      }
});

Another alternative will be to use the data-ajax on a link.

<a href="/ControllerName/ActionName/" data-ajax="true" data-ajax-method="GET" data-ajax-mode="replace" data-ajax-update="#_content">Click Me!</a>

Assuming u had a div with the I'd _content, this will call the action and replace the content inside that div with the data returned from that action.

<div id="_content"></div>

Not really a direct answer to ur question but its some info u should be aware of ;).

I agree this code works, to size an ImageIcon from a file for display while keeping the aspect ratio I have used the below.

/*
 * source File of image, maxHeight pixels of height available, maxWidth pixels of width available
 * @return an ImageIcon for adding to a label
 */


public ImageIcon rescaleImage(File source,int maxHeight, int maxWidth)
{
    int newHeight = 0, newWidth = 0;        // Variables for the new height and width
    int priorHeight = 0, priorWidth = 0;
    BufferedImage image = null;
    ImageIcon sizeImage;

    try {
            image = ImageIO.read(source);        // get the image
    } catch (Exception e) {

            e.printStackTrace();
            System.out.println("Picture upload attempted & failed");
    }

    sizeImage = new ImageIcon(image);

    if(sizeImage != null)
    {
        priorHeight = sizeImage.getIconHeight(); 
        priorWidth = sizeImage.getIconWidth();
    }

    // Calculate the correct new height and width
    if((float)priorHeight/(float)priorWidth > (float)maxHeight/(float)maxWidth)
    {
        newHeight = maxHeight;
        newWidth = (int)(((float)priorWidth/(float)priorHeight)*(float)newHeight);
    }
    else 
    {
        newWidth = maxWidth;
        newHeight = (int)(((float)priorHeight/(float)priorWidth)*(float)newWidth);
    }


    // Resize the image

    // 1. Create a new Buffered Image and Graphic2D object
    BufferedImage resizedImg = new BufferedImage(newWidth, newHeight, BufferedImage.TYPE_INT_RGB);
    Graphics2D g2 = resizedImg.createGraphics();

    // 2. Use the Graphic object to draw a new image to the image in the buffer
    g2.setRenderingHint(RenderingHints.KEY_INTERPOLATION, RenderingHints.VALUE_INTERPOLATION_BILINEAR);
    g2.drawImage(image, 0, 0, newWidth, newHeight, null);
    g2.dispose();

    // 3. Convert the buffered image into an ImageIcon for return
    return (new ImageIcon(resizedImg));
}

This is what I've been using for development:

<?xml version="1.0" ?>
<cross-domain-policy>
<allow-access-from domain="*" />
</cross-domain-policy>

This is a very liberal approach, but is fine for my application.

As others have pointed out below, beware the risks of this.

Looking at your code, I'm not sure why you're getting that error, but I had this same error but with EditText fields.

Changing android:inputType="text" (or any of the other inputType text variations) to android:inputType="textNoSuggestions" (or android:inputType="textEmailAddress|textNoSuggestions", for example) fixed it for me.

You can also set this in Code with something like

mInputField.setInputType(InputType.TYPE_CLASS_TEXT | InputType.TYPE_TEXT_FLAG_NO_SUGGESTIONS);

Looks like Android assumes by default that EditText fields will have suggestions. When they don't, it errors. Not 100% confident in that explanation, but the above mentioned changes fixed it for me.

Hope this helps!

In general the point of the SettingWithCopyWarning is to show users (and especially new users) that they may be operating on a copy and not the original as they think. There are false positives (IOW if you know what you are doing it could be ok). One possibility is simply to turn off the (by default warn) warning as @Garrett suggest.

Here is another option:

In [1]: df = DataFrame(np.random.randn(5, 2), columns=list('AB'))

In [2]: dfa = df.ix[:, [1, 0]]

In [3]: dfa.is_copy
Out[3]: True

In [4]: dfa['A'] /= 2
/usr/local/bin/ipython:1: SettingWithCopyWarning: A value is trying to be set on a copy of a slice from a DataFrame.
Try using .loc[row_index,col_indexer] = value instead
  #!/usr/local/bin/python

You can set the is_copy flag to False, which will effectively turn off the check, for that object:

In [5]: dfa.is_copy = False

In [6]: dfa['A'] /= 2

If you explicitly copy then no further warning will happen:

In [7]: dfa = df.ix[:, [1, 0]].copy()

In [8]: dfa['A'] /= 2

The code the OP is showing above, while legitimate, and probably something I do as well, is technically a case for this warning, and not a false positive. Another way to not have the warning would be to do the selection operation via reindex, e.g.

quote_df = quote_df.reindex(columns=['STK', ...])

Or,

quote_df = quote_df.reindex(['STK', ...], axis=1)  # v.0.21

One of the first things that you should check is that the SQL Server (MSSQLSERVER) is started. You can go to the Services Console (services.msc) and look for SQL Server (MSSQLSERVER) to see that it is started. If not, then start the service.

You could also do this through an elevated command prompt by typing net start mssqlserver.

Essentially, PHPStorm = WebStorm + PHP, SQL and more.

BUT (and this is a very important "but") because it is capable of parsing so much more, it quite often fails to parse Node.js dependencies, as they (probably) conflict with some other syntax it is capable of parsing.

The most notable example of that would be Mongoose model definition, where WebStorm easily recognizes mongoose.model method, whereas PHPStorm marks it as unresolved as soon as you connect Node.js plugin.

Surprisingly, it manages to resolve the method if you turn the plugin off, but leave the core modules connected, but then it cannot be used for debugging. And this happens to quite a few methods out there.

All this goes for PHPStorm 8.0.1, maybe in later releases this annoying bug would be fixed.

Only use git rm --cached [file] to remove a file from the index.

git reset <filename> can be used to remove added files from the index given the files are never committed.

% git add First.txt
% git ls-files
First.txt
% git commit -m "First"   
% git ls-files            
First.txt
% git reset First.txt
% git ls-files              
First.txt

NOTE: git reset First.txt has no effect on index after the commit.

Which brings me to the topic of git restore --staged <file>. It can be used to (presumably after the first commit) remove added files from the index given the files are never committed.

% git add Second.txt              
% git status        
On branch master
Changes to be committed:
  (use "git restore --staged <file>..." to unstage)
    new file:   Second.txt
% git ls-files       
First.txt
Second.txt
% git restore --staged Second.txt
% git ls-files 
First.txt
% git add Second.txt 
% git commit -m "Second"
% git status            
On branch master
nothing to commit, working tree clean
% git ls-files 
First.txt         
Second.txt
Desktop/Test% git restore --staged .
Desktop/Test% git ls-files
First.txt                   
Second.txt
Desktop/Test% git reset .                    
Desktop/Test% git ls-files
First.txt
Second.txt
% git rm --cached -r .
rm 'First.txt'
rm 'Second.txt'
% git ls-files  

tl;dr Look at last 15 lines. If you don't want to be confused with first commit, second commit, before commit, after commit.... always use git rm --cached [file]

• TortoiseMerge (part of ToroiseSVN) is much better than kdiff3 (I use both and can compare);
• p4merge (from Perforce) works also very well;
• Diffuse isn't so bad;
• Diffmerge from SourceGear has only one flaw in handling UTF8-files without BOM, making in unusable for this case.

If you want to have images about same topic, you ca use subfigure package and construction:

\begin{figure}
 \subfigure[first image]{\includegraphics{image}\label{first}}
 \subfigure[second image]{\includegraphics{image}\label{second}}
 \caption{main caption}\label{main_label}
\end{figure}

If you want to have, for example two, different images next to each other you can use:

\begin{figure}
 \begin{minipage}{.5\textwidth}
  \includegraphics{image}
  \caption{first}
 \end{minipage}
 \begin{minipage}{.5\textwidth}
  \includegraphics{image}
  \caption{second}
 \end{minipage}
\end{figure}

For images in columns you will have [1] [2] [3] [4] in the source, but it will look like

[1] [3]

[2] [4].

I know this is very old, but I got the same issue when I had to navigate through an angular route and the dialog is open, it remained open. So I got a workaround to call the close method in the route controller destructor. But got this above mentioned error if the dialog was not open. So the answer is if you are closing the dialog prior to initialization it will through this error. To check if the dialog is open then close it wrap your close state in this condition.

if($('#mydialog').dialog('isOpen')) { //close dialog code}

This jQuery solution works for me in Chrome and Firefox, for both Ctrl+S and Cmd+S.

$(document).keydown(function(e) {

    var key = undefined;
    var possible = [ e.key, e.keyIdentifier, e.keyCode, e.which ];

    while (key === undefined && possible.length > 0)
    {
        key = possible.pop();
    }

    if (key && (key == '115' || key == '83' ) && (e.ctrlKey || e.metaKey) && !(e.altKey))
    {
        e.preventDefault();
        alert("Ctrl-s pressed");
        return false;
    }
    return true;
}); 

You can use the MultilineLabel component in the Jide Open Source Components.

First you can use a Paginator. This is as simple as:

$allUsers = User::paginate(15);

$someUsers = User::where('votes', '>', 100)->paginate(15);

The variables will contain an instance of Paginator class. all of your data will be stored under data key.

Or you can do something like:

Old versions Laravel.

Model::all()->take(10)->get();

Newer version Laravel.

Model::all()->take(10);

For more reading consider these links:

• pagination docs
• passing data to views
• Eloquent basic usage

Here's a simpler (but not so short) version which doesn't require try-catch:

Map<String, String> data = new HashMap<>();
data.put("user", "[email protected]");
data.put("pass", "123");

JSONObject jsonData = new JSONObject(data);

If you want to add a jsonObject into a field, you can do this way:

data.put("socialMedia", (new JSONObject()).put("facebookId", "1174989895893400"));
data.put("socialMedia", (new JSONObject()).put("googleId", "106585039098745627377"));

Unfortunately it needs a try-catch because of the put() method.

IF you want to avoid try-catch again (not very recommended, but it's ok if you can guarantee well formated json strings), you might do this way:

data.put("socialMedia", "{ 'facebookId': '1174989895893400' }");

You can do the same about JsonArrays and so on.

Cheers.

This won't really work at all. There is no date type in JSON. I would recommend to serialize to ISO8601 back and forth (for format agnostics and JS compat). Consider that you have to know which fields contain dates.
