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

from subprocess import PIPE, Popen


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

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

Use

$ mysqladmin -u <db_user_name> -p create <db_name>

You will be prompted for password. Also make sure the mysql user you use has privileges to create database.

>>> import datetime
>>> d = datetime.datetime.strptime('2011-06-09', '%Y-%m-%d')
>>> d.strftime('%b %d,%Y')
'Jun 09,2011'

In pre-2.5 Python, you can replace datetime.strptime with time.strptime, like so (untested): datetime.datetime(*(time.strptime('2011-06-09', '%Y-%m-%d')[0:6]))

In Opera 12 when you bind using the plain JavaScript, 'oTransitionEnd' will work:

document.addEventListener("oTransitionEnd", function(){
    alert("Transition Ended");
});

however if you bind through jQuery, you need to use 'otransitionend'

$(document).bind("otransitionend", function(){
    alert("Transition Ended");
});

In case you are using Modernizr or bootstrap-transition.js you can simply do a change:

var transEndEventNames = {
    'WebkitTransition' : 'webkitTransitionEnd',
    'MozTransition'    : 'transitionend',
    'OTransition'      : 'oTransitionEnd otransitionend',
    'msTransition'     : 'MSTransitionEnd',
    'transition'       : 'transitionend'
},
transEndEventName = transEndEventNames[ Modernizr.prefixed('transition') ];

You can find some info here as well http://www.ianlunn.co.uk/blog/articles/opera-12-otransitionend-bugs-and-workarounds/

You do not need any client side code if doing this is ASP.NET. The example below is a boostrap input box with a search button with an fontawesome icon.

You will see that in place of using a regular < div > tag with a class of "input-group" I have used a asp:Panel. The DefaultButton property set to the id of my button, does the trick.

In example below, after typing something in the input textbox, you just hit enter and that will result in a submit.

<asp:Panel DefaultButton="btnblogsearch" runat="server" CssClass="input-group blogsearch">
<asp:TextBox ID="txtSearchWords" CssClass="form-control" runat="server" Width="100%" Placeholder="Search for..."></asp:TextBox>
<span class="input-group-btn">
    <asp:LinkButton ID="btnblogsearch" runat="server" CssClass="btn btn-default"><i class="fa fa-search"></i></asp:LinkButton>
</span></asp:Panel>

I like to run the following:

git commit -am "message";git push

  <script>
function equalHeight(group) {
   tallest = 0;
   group.each(function() {
      thisHeight = $(this).height();
      if(thisHeight > tallest) {
         tallest = thisHeight;
      }
   });
   group.height(tallest);
}
$(document).ready(function() {
   equalHeight($(".column"));
});
</script>

There are few mistakes you are doing:

1. You need to add proper object in the array in addRow method
2. You can use splice method to remove an element from an array at particular index.
3. You need to pass the current row as prop to my-item component, where this can be modified.

You can see working code here.

addRow(){
   this.rows.push({description: '', unitprice: '' , code: ''}); // what to push unto the rows array?
},
removeRow(index){
   this. itemList.splice(index, 1)
}

When you have many HTML inputs named C[] what you get in the POST array on the other end is an array of these values in $_POST['C']. So when you echo that, you are trying to print an array, so all it does is print Array and a notice.

To print properly an array, you either loop through it and echo each element, or you can use print_r.

Alternatively, if you don't know if it's an array or a string or whatever, you can use var_dump($var) which will tell you what type it is and what it's content is. Use that for debugging purposes only.

select
  sum(a) as atotal,
  sum(b) as btotal,
  sum(c) as ctotal
from
  yourtable t
where
  t.id in (1, 2, 3)

SQL Developer can show the blob as an image (at least it works for jpegs). In the Data view, double click on the BLOB field to get the "pencil" icon. Click on the pencil to get a dialog that will allow you to select a "View As Image" checkbox.

If you're using PHP you can funnel your request to Node scripts via shell_exec, passing arguments to scripts as JSON strings in the command line. Example call:

<?php
    shell_exec("node nodeScript.js"); // without arguments
    shell_exec("node nodeScript.js '{[your JSON here]}'"); //with arguments
?>

The caveat is you need to be very careful about handling user data when it goes anywhere near a command line. Example nightmare:

<?php
    $evilUserData = "'; [malicious commands here];";
    shell_exec("node nodeScript.js '{$evilUserData}'");
?>

You could just set the width to auto. Then the width of the div will equal 0 if it has no content.

width:auto;

its kind of hacky but it works well-ish

 function close_frame(){
    if(!window.should_close){
        window.should_close=1;
    }else if(window.should_close==1){
        location.reload();
        //or iframe hide or whatever
    }
 }

 <iframe src="iframe_index.php" onload="close_frame()"></iframe>

then inside the frame

$('#close_modal_main').click(function(){
        window.location = 'iframe_index.php?close=1';
});

and if you want to get fancy through a

if(isset($_GET['close'])){
  die;
}

at the top of your frame page to make that reload unnoticeable

so basically the first time the frame loads it doesnt hide itself but the next time it loads itll call the onload function and the parent will have a the window var causing the frame to close

Maybe because its 2013-01-29 so +1 month would be 2013-02-29 which doesn't exist so it would be 2013-03-01

You could try

date('m/d/y h:i a',(strtotime('next month',strtotime(date('m/01/y')))));

from the comments on http://php.net/manual/en/function.strtotime.php

maybe a little bit tricky, but you could send an sms to the emulator by using the emulator control. then you do not have to retype all the text if it is longer and can copy-paste it in the emulator.

another way: connect to emulator via "telnet localhost PORT" and then use hardware event sending to send a text input event to the emulator (needs to be UTF-8). look at this

If you have an Order class, adding a property that references another class in your model, for instance Customer should be enough to let EF know there's a relationship in there:

public class Order
{
    public int ID { get; set; }

    // Some other properties

    // Foreign key to customer
    public virtual Customer Customer { get; set; }
}

You can always set the FK relation explicitly:

public class Order
{
    public int ID { get; set; }

    // Some other properties

    // Foreign key to customer
    [ForeignKey("Customer")]
    public string CustomerID { get; set; }
    public virtual Customer Customer { get; set; }
}

The ForeignKeyAttribute constructor takes a string as a parameter: if you place it on a foreign key property it represents the name of the associated navigation property. If you place it on the navigation property it represents the name of the associated foreign key.

What this means is, if you where to place the ForeignKeyAttribute on the Customer property, the attribute would take CustomerID in the constructor:

public string CustomerID { get; set; }
[ForeignKey("CustomerID")]
public virtual Customer Customer { get; set; }

EDIT based on Latest Code You get that error because of this line:

[ForeignKey("Parent")]
public Patient Patient { get; set; }

EF will look for a property called Parent to use it as the Foreign Key enforcer. You can do 2 things:

1) Remove the ForeignKeyAttribute and replace it with the RequiredAttribute to mark the relation as required:

[Required]
public virtual Patient Patient { get; set; }

Decorating a property with the RequiredAttribute also has a nice side effect: The relation in the database is created with ON DELETE CASCADE.

I would also recommend making the property virtual to enable Lazy Loading.

2) Create a property called Parent that will serve as a Foreign Key. In that case it probably makes more sense to call it for instance ParentID (you'll need to change the name in the ForeignKeyAttribute as well):

public int ParentID { get; set; }

In my experience in this case though it works better to have it the other way around:

[ForeignKey("Patient")]
public int ParentID { get; set; }

public virtual Patient Patient { get; set; }

The 502 error appears because nginx cannot hand off to php5-cgi. You can try reconfiguring php5-cgi to use unix sockets as opposed to tcp .. then adjust the server config to point to the socket instead of the tcp ...

ps auxww | grep php5-cgi #-- is the process running?  
netstat -an | grep 9000 # is the port open? 

I'm not sure how you could just check if something isn't undefined and at the same time get an error that it is undefined. What browser are you using?

You could check in the following way (extra = and making length a truthy evaluation)

if (typeof(sub.from) !== 'undefined' && sub.from.length) {

[update]

I see that you reset sub and thereby reset sub.from but fail to re check if sub.from exist:

for (var i = 0; i < sub.from.length; i++) {//<== assuming sub.from.exist
            mainid = sub.from[i]['id'];
            var sub = afcHelper_Submissions[mainid]; // <== re setting sub

My guess is that the error is not on the if statement but on the for(i... statement. In Firebug you can break automatically on an error and I guess it'll break on that line (not on the if statement).

Simple answer is :

$('#first').select2().val()

and you can write by this way also:

 $('#first').val()

Good question.

• When in a CSS file, URLs will be relative to the CSS file.

• When writing properties using JavaScript, URLs should always be relative to the page (the main resource requested).

There is no tilde functionality built-in in JS that I know of. The usual way would be to define a JavaScript variable specifying the base path:

<script type="text/javascript">

  directory_root = "http://www.example.com/resources";

</script> 

and to reference that root whenever you assign URLs dynamically.

None of the current answers show the InputStream being closed (this will leak a file descriptor), and/or don't deal with .getResourceAsStream() returning null when the resource is not found (this will lead to a NullPointerException with the confusing message, "inStream parameter is null"). You need something like the following:

String propertiesFilename = "server.properties";
Properties prop = new Properties();
try (var inputStream = getClass().getClassLoader().getResourceAsStream(propertiesFilename)) {
    if (inputStream == null) {
        throw new FileNotFoundException(propertiesFilename);
    }
    prop.load(inputStream);
} catch (IOException e) {
    throw new RuntimeException(
                "Could not read " + propertiesFilename + " resource file: " + e);
}

You're missing quotes around your string:

...
var htmlString="<?php echo $htmlString; ?>";
...

Nothing works from this tread. "forRoot" doesn't help.

Sorry. Sorted this out. I've managed to make it work by setting correct "routes" for this "forRoot" router setup routine

    import {RouterModule, Routes} from '@angular/router';    
    import {AppComponent} from './app.component';
    
    const appRoutes: Routes = [
      {path: 'UI/part1/Details', component: DetailsComponent}
    ];
    
    @NgModule({
      declarations: [
        AppComponent,
        DetailsComponent
      ],
      imports: [
        BrowserModule,
        HttpClientModule,
        RouterModule.forRoot(appRoutes)
      ],
      providers: [DetailsService],
      bootstrap: [AppComponent]
    })

Also may be helpful (spent some time to realize this) Optional route part:

    const appRoutes: Routes = [
       {path: 'UI/part1/Details', component: DetailsComponent},
       {path: ':project/UI/part1/Details', component: DetailsComponent}
    ];

Second rule allows to open URLs like
hostname/test/UI/part1/Details?id=666
and
hostname/UI/part1/Details?id=666

Been working as a frontend developer since 2012 but never stuck in a such over-complicated thing as angular2 (I have 3 years experience with enterprise level ExtJS)

Normal ways would be Integer.toString(i) or String.valueOf(i).

int i = 5;
String strI = String.valueOf(i);

Or

int aInt = 1;    
String aString = Integer.toString(aInt);

Android documentation is clear on this.Go to the below page.Underneath,there are two columns with names "OLD BUILD ARTIFACT" and "AndroidX build artifact"

https://developer.android.com/jetpack/androidx/migrate

Now you have many dependencies in gradle.Just match those with Androidx build artifacts and replace them in the gradle.

That won't be enough.

Go to your MainActivity (repeat this for all activities) and remove the word AppCompact Activity in the statement "public class MainActivity extends AppCompatActivity " and write the same word again.But this time androidx library gets imported.Until now appcompact support file got imported and used (also, remove that appcompact import statement).

Also,go to your layout file. Suppose you have a constraint layout,then you can notice that the first line constraint layout in xml file have something related to appcompact.So just delete it and write Constraint layout again.But now androidx related constraint layout gets added.

repeat this for as many activities and as many xml layout files..

But don't worry: Android Studio displays all such possible errors while compiling.

Not able to understand your actual problem but your case statement is incorrect

Posting this here because I always come across this question when I forget to include JavaScript in the search and wind up on this question instead of the one above. If this helps you, be sure to upvote that answer as well.

Note: For older versions of bootstrap (less than 3 or so), you'll proably need to search the page's JavaScript or CSS files for the bootstrap version. Just came across this on an app using bootstrap 2.3.2. In this case, the (current) top answer is likely the correct one, you'll need to search the source code for the bootstrap find what version it uses.

Just use the array of options, to see, which option is currently selected.

$options = array( 'one', 'two', 'three' );

$output = '';
for( $i=0; $i<count($options); $i++ ) {
  $output .= '<option ' 
             . ( $_GET['sel'] == $options[$i] ? 'selected="selected"' : '' ) . '>' 
             . $options[$i] 
             . '</option>';
}

_{Sidenote: I would define a value to be some kind of id for each element, else you may run into problems, when two options have the same string representation.}

For chat applications or any other application that is in constant conversation with the server, WebSockets are the best option. However, you can only use WebSockets with a server that supports them, so that may limit your ability to use them if you cannot install the required libraries. In which case, you would need to use Long Polling to obtain similar functionality.

If the whole purpose is to communicate data with some other application, use Intent's sendBroadcast methods.

When the text is a number with leading zeros, then do: (Cuando el texto es un número que empieza por ceros, hacer)

All the answers here use third party libraries while rendering HTML to an image can be relatively simple in pure Javascript. There is was even an article about it on the canvas section on MDN.

The trick is this:

• create an SVG with a foreignObject node containing your XHTML
• set the src of an image to the data url of that SVG
• drawImage onto the canvas
• set canvas data to target image.src

const {body} = document_x000D_
_x000D_
const canvas = document.createElement('canvas')_x000D_
const ctx = canvas.getContext('2d')_x000D_
canvas.width = canvas.height = 100_x000D_
_x000D_
const tempImg = document.createElement('img')_x000D_
tempImg.addEventListener('load', onTempImageLoad)_x000D_
tempImg.src = 'data:image/svg+xml,' + encodeURIComponent('<svg xmlns="http://www.w3.org/2000/svg" width="100" height="100"><foreignObject width="100%" height="100%"><div xmlns="http://www.w3.org/1999/xhtml"><style>em{color:red;}</style><em>I</em> lick <span>cheese</span></div></foreignObject></svg>')_x000D_
_x000D_
const targetImg = document.createElement('img')_x000D_
body.appendChild(targetImg)_x000D_
_x000D_
function onTempImageLoad(e){_x000D_
  ctx.drawImage(e.target, 0, 0)_x000D_
  targetImg.src = canvas.toDataURL()_x000D_
}

Some things to note

• The HTML inside the SVG has to be XHTML
• For security reasons the SVG as data url of an image acts as an isolated CSS scope for the HTML since no external sources can be loaded. So a Google font for instance has to be inlined using a tool like this one.
• Even when the HTML inside the SVG exceeds the size of the image it wil draw onto the canvas correctly. But the actual height cannot be measured from that image. A fixed height solution will work just fine but dynamic height will require a bit more work. The best is to render the SVG data into an iframe (for isolated CSS scope) and use the resulting size for the canvas.

You can join your array using the following:

string.Join(",", Client);

Then you can output anyway you want. You can change the comma to what ever you want, a space, a pipe, or whatever.

Wolfram has a closed form solution for fitting an exponential. They also have similar solutions for fitting a logarithmic and power law.

I found this to work better than scipy's curve_fit. Especially when you don't have data "near zero". Here is an example:

import numpy as np
import matplotlib.pyplot as plt

# Fit the function y = A * exp(B * x) to the data
# returns (A, B)
# From: https://mathworld.wolfram.com/LeastSquaresFittingExponential.html
def fit_exp(xs, ys):
    S_x2_y = 0.0
    S_y_lny = 0.0
    S_x_y = 0.0
    S_x_y_lny = 0.0
    S_y = 0.0
    for (x,y) in zip(xs, ys):
        S_x2_y += x * x * y
        S_y_lny += y * np.log(y)
        S_x_y += x * y
        S_x_y_lny += x * y * np.log(y)
        S_y += y
    #end
    a = (S_x2_y * S_y_lny - S_x_y * S_x_y_lny) / (S_y * S_x2_y - S_x_y * S_x_y)
    b = (S_y * S_x_y_lny - S_x_y * S_y_lny) / (S_y * S_x2_y - S_x_y * S_x_y)
    return (np.exp(a), b)


xs = [33, 34, 35, 36, 37, 38, 39, 40, 41, 42]
ys = [3187, 3545, 4045, 4447, 4872, 5660, 5983, 6254, 6681, 7206]

(A, B) = fit_exp(xs, ys)

plt.figure()
plt.plot(xs, ys, 'o-', label='Raw Data')
plt.plot(xs, [A * np.exp(B *x) for x in xs], 'o-', label='Fit')

plt.title('Exponential Fit Test')
plt.xlabel('X')
plt.ylabel('Y')
plt.legend(loc='best')
plt.tight_layout()
plt.show()

in your code, just after 'do while' statement, add this line..

`Wscript.sleep 10000`

This will let your script sleep for 10 secs and let your system take rest. Else your processor will be running this script million times a second and this will definitely load your processor.

To kill it, just goto taskmanager and kill wscript.exe or if it is not found, you will find cscript.exe, kill it pressing delete button. These would be present in process tab of your taskmanager.

Once you add that line in code, I dont think you need to kill this process. It will not load your CPU.

Have a great day.

It's a warning, not an error. It occurs because fsevents is an optional dependency, used only when project is run on macOS environment (the package provides 'Native Access to Mac OS-X FSEvents').

And since you're running your project on Windows, fsevents is skipped as irrelevant.

There is a PR to fix this behaviour here: https://github.com/npm/cli/pull/169

If .toggle is not working I would do the next:

var flag = false;
$('#click_advance').click(function(){
    if( flag == false){
       $('#display_advance').show('1000');
         // Add more code
       flag = true;
    }
    else{
       $('#display_advance').hide('1000');
       // Add more code
       flag = false;
    }
}

It's a little bit more code, but it works

var googleResponse = jQuery('#g-recaptcha-response').val();
if (!googleResponse) {
    $('<p style="color:red !important" class=error-captcha"><span class="glyphicon glyphicon-remove " ></span> Please fill up the captcha.</p>" ').insertAfter("#html_element");
    return false;
} else {            
    return true;
}

Put this in a function. Call this function on submit... #html_element is my empty div.

function xxxx() {
// submit or validate here , disable after that using below
  document.getElementById('buttonId').disabled = 'disabled';
  document.getElementById('buttonId').disabled = '';
}

#!/bin/bash -e

should suffice.

For me on Eclipse Neon I followed Trismegistos answer here above , YET I also added an additional step:

• Go to project --> Properties --> C++ General --> Preprocessor Include paths,Macros etc. --> Providers --> CDT Cross GCC Built-in Compiler Settings, append the flag "-std=c++11"

Hit apply and OK.

Cheers,

Guy.

setEnabled(false) works perfectly for me.

The idea is I write { setEnabled(true); } in the beginning and just make it false on the first click of the button.

To answer your main question, you want to use the subplot command. I think changing plt.figure(i) to plt.subplot(4,4,i+1) should work.

1. you need to convert SVG to XML to use in android project.

1.1 you can do this with this site: http://inloop.github.io/svg2android/ but it does not support all the features of SVG like some gradients.

1.2 you can convert via android studio but it might use some features that only supports API 24 and higher that cuase crashe your app in older devices.

and add vectorDrawables.useSupportLibrary = true in gradle file and use like this:

<android.support.v7.widget.AppCompatImageView
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                app:srcCompat="@drawable/ic_item1" />

2. use this library https://github.com/MegatronKing/SVG-Android that supports these features : https://github.com/MegatronKing/SVG-Android/blob/master/support_doc.md

add this code in application class:

public void onCreate() {
    SVGLoader.load(this)
}

and use the SVG like this :

<ImageView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:src="@drawable/ic_android_red"/>

1.this is my answer for your problem.

.ModalCarrot::before {
content:'';
background: url('blackCarrot.png'); /*url of image*/
height: 16px; /*height of image*/
width: 33px;  /*width of image*/
position: absolute;
}

This can also be done with a timeout:

# Ping until timeout or 1 successful packet
ping -w (timeout) -c 1

If obj Is Nothing Then
    ' need to initialize obj: '
    Set obj = ...
Else
    ' obj already set / initialized. '
End If

Or, if you prefer it the other way around:

If Not obj Is Nothing Then
    ' obj already set / initialized. '
Else
    ' need to initialize obj: '
    Set obj = ...
End If

To elaborate on @Marc B's answer,

$ passwd
$ while [ $? -ne 0 ]; do !!; done

Is nice way of doing the same thing that's not command specific.

class Logo extends JPanel
{
    Logo()
    {
        //code
    }
    @Override
    public void paintComponent(Graphics g) 
    {
        super.paintComponent(g);
        ImageIcon img = new ImageIcon("logo.jpg");
        g.drawImage(img.getImage(), 0, 0, this.getWidth(), this.getHeight(), null);
    }
}

the correct answer is @chepner's

EXT=java
for i in *.${EXT}; do
    ...
done

however, here's a small trick to check whether a filename has a given extensions:

EXT=java
for i in *; do
    if [ "${i}" != "${i%.${EXT}}" ];then
        echo "I do something with the file $i"
    fi
done

In my case i did following thing. In the UserMaster userId is PK and in UserAccess userId is FK of UserMaster

UserAccess.belongsTo(UserMaster,{foreignKey: 'userId'});
UserMaster.hasMany(UserAccess,{foreignKey : 'userId'});
var userData = await UserMaster.findAll({include: [UserAccess]});

A MUCH faster solution for large dataset and limited number of colors is the use of Pandas and the groupby function:

import pandas as pd
import numpy as np
import matplotlib.pyplot as plt
import time


# a generic set of data with associated colors
nsamples=1000
x=np.random.uniform(0,10,nsamples)
y=np.random.uniform(0,10,nsamples)
colors={0:'r',1:'g',2:'b',3:'k'}
c=[colors[i] for i in np.round(np.random.uniform(0,3,nsamples),0)]

It looks like details is an array of hashes. So item inside of your block will be the whole hash. Therefore, to check the :qty key, you'd do something like the following:

details.select{ |item| item[:qty] != "" }

That will give you all items where the :qty key isn't an empty string.

you need to do an ajax HEAD request to get the filesize. with jquery it's something like this

  var req = $.ajax({
    type: "HEAD",
    url: yoururl,
    success: function () {
      alert("Size is " + request.getResponseHeader("Content-Length"));
    }
  });

I think the easiest way is creating a dummy item on index 0 saying "select one" and then on saving maybe check that selection is not 0.

Perhaps this can be useful for someone:

In my case, I was getting an array of objects, each containing a date set by Mongoose.

I used:

ng-repeat="comment in post.comments | orderBy : sortComment : true"

And defined the function:

$scope.sortComment = function(comment) {
    var date = new Date(comment.created);
    return date;
};

This worked for me.

Put into address line chrome://about. You will see links to all possible dev pages.

var myVar = $("#start").find('myClass').val();

needs to be

var myVar = $("#start").find('.myClass').val();

Remember the CSS selector rules require "." if selecting by class name. The absence of "." is interpreted to mean searching for <myclass></myclass>.

Use the java.lang.reflect.Method object and call invoke

We had this in many other cases, what we decided internally is to always have a wrapper for the controller/directive so that we don't need to think about it. Here is you example with our wrapper.

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.0rc1/angular.min.js"></script>

<script>
    function main($scope) {
        $scope.thisScope = $scope;
        $scope.testa = false;
        $scope.testb = false;
        $scope.testc = false;
        $scope.testd = false;
    }
</script>

<div ng-app >
    <div ng-controller="main">

        Test A: {{testa}}<br />
        Test B: {{testb}}<br />
        Test C: {{testc}}<br />
        Test D: {{testd}}<br />

        <div>
            testa (without ng-if): <input type="checkbox" ng-model="thisScope.testa" />
        </div>
        <div ng-if="!testa">
            testb (with ng-if): <input type="checkbox" ng-model="thisScope.testb" />
        </div>
        <div ng-show="!testa">
            testc (with ng-show): <input type="checkbox" ng-model="thisScope.testc" />
        </div>
        <div ng-hide="testa">
            testd (with ng-hide): <input type="checkbox" ng-model="thisScope.testd" />
        </div>

    </div>
</div>

Hopes this helps, Yishay

You will get the proxy host and port from your server administrator or support.

After that set up

npm config set http_proxy http://username:[email protected]:itsport
npm config set proxy http://username:[email protected]:itsport

If there any special character in password try with % urlencode. Eg:- pound(hash) shuold be replaced by %23.

This worked for me...

I was stuck with ast.literal_eval(). I was trying it in IntelliJ IDEA debugger, and it kept returning None on debugger output.

But later when I assigned its output to a variable and printed it in code. It worked fine. Sharing code example:

import ast
sample_string = '[{"id":"XYZ_GTTC_TYR", "name":"Suction"}]'
output_value = ast.literal_eval(sample_string)
print(output_value)

Its python version 3.6.

Ok, looks like your post got editted...

double foo[4];
double *bar_1 = &foo[0];

See how you can use the & to get the address of the beginning of the array structure? The following

Foo_1(double *bar, int size){ return bar[size-1]; }
Foo_2(double bar[], int size){ return bar[size-1]; }

will do the same thing.

In config.php add or edit the following lines to this:
------------------------------------------------------
$config['log_threshold'] = 4; // (1/2/3)
$config['log_path'] = '/home/path/to/application/logs/';

Run this command in the terminal:
----------------------------------
sudo chmod -R 777 /home/path/to/application/logs/

Being DialogFragment a wrapper for the Dialog class, you should set a theme to your base Dialog to get the animation you want:

public class CustomDialogFragment extends DialogFragment implements OnEditorActionListener
{
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) 
    {
        return super.onCreateView(inflater, container, savedInstanceState);
    }

    @Override
    public Dialog onCreateDialog(Bundle savedInstanceState) 
    {
        // Set a theme on the dialog builder constructor!
        AlertDialog.Builder builder = 
            new AlertDialog.Builder( getActivity(), R.style.MyCustomTheme );

        builder  
        .setTitle( "Your title" )
        .setMessage( "Your message" )
        .setPositiveButton( "OK" , new DialogInterface.OnClickListener() 
            {      
              @Override
              public void onClick(DialogInterface dialog, int which) {
              dismiss();                  
            }
        });
        return builder.create();
    }
}

Then you just need to define the theme that will include your desired animation. In styles.xml add your custom theme:

<style name="MyCustomTheme" parent="@android:style/Theme.Panel">
    <item name="android:windowAnimationStyle">@style/MyAnimation.Window</item>
</style>

<style name="MyAnimation.Window" parent="@android:style/Animation.Activity"> 
    <item name="android:windowEnterAnimation">@anim/anim_in</item>
    <item name="android:windowExitAnimation">@anim/anim_out</item>
</style>    

Now add the animation files in the res/anim folder:

( the android:pivotY is the key )

anim_in.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
    <scale
        android:interpolator="@android:anim/linear_interpolator"
        android:fromXScale="0.0"
        android:toXScale="1.0"
        android:fromYScale="0.0"
        android:toYScale="1.0"
        android:fillAfter="false"
        android:startOffset="200"
        android:duration="200" 
        android:pivotX = "50%"
        android:pivotY = "-90%"
    />
    <translate
        android:fromYDelta="50%"
        android:toYDelta="0"
        android:startOffset="200"
        android:duration="200"
    />
</set>

anim_out.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
    <scale
        android:interpolator="@android:anim/linear_interpolator"
        android:fromXScale="1.0"
        android:toXScale="0.0"
        android:fromYScale="1.0"
        android:toYScale="0.0"
        android:fillAfter="false"
        android:duration="200" 
        android:pivotX = "50%"        
        android:pivotY = "-90%"        
    />
    <translate
        android:fromYDelta="0"
        android:toYDelta="50%"
        android:duration="200"
    />
</set>

Finally, the tricky thing here is to get your animation grow from the center of each row. I suppose the row is filling the screen horizontally so, on one hand the android:pivotX value will be static. On the other hand, you can't modify the android:pivotY value programmatically.

What I suggest is, you define several animations each of which having a different percentage value on the android:pivotY attribute (and several themes referencing those animations). Then, when the user taps the row, calculate the Y position in percentage of the row on the screen. Knowing the position in percentage, assign a theme to your dialog that has the appropriate android:pivotY value.

It is not a perfect solution but could do the trick for you. If you don't like the result, then I would suggest forgetting the DialogFragment and animating a simple View growing from the exact center of the row.

Good luck!

Had the same issue with Ionic routing.

Simple solution is to use the name of the state - basically state.go(state name)

.state('tab.search', {
    url: '/search',
    views: {
      'tab-search': {
        templateUrl: 'templates/search.html',
        controller: 'SearchCtrl'
      }
    }
  })

And in controller you can use $state.go('tab.search');

The correct way of building client/server Microsoft Access applications where the data is stored in a RDBMS is to use the Linked Table method. This ensures Data Isolation and Concurrency is maintained between the Microsoft Access client application and the RDBMS data with no additional and unnecessary programming logic and code which makes maintenance more difficult, and adds to development time.

see: http://claysql.blogspot.com/2014/08/normal-0-false-false-false-en-us-x-none.html

split with the + sign like this way

String a = tv.getText().toString();
String aa[];
if(a.contains("+"))
    aa = a.split("+");

now convert the array

Integer.parseInt(aa[0]); // and so on

Michael and yoda are both right. What you can do is use the <p> tag, which, being a block tag, uses a bottom-margin to offset the following block, so you can do something similar to this to get bigger spacing:

<p>
    A block of text.
</p>
<p>
    Another block
</p>

Another alternative is to use the block <hr> tag, with which you can explicitly define the height of the spacing.

I usually use getReference method when i do not need to access database state (I mean getter method). Just to change state (I mean setter method). As you should know, getReference returns a proxy object which uses a powerful feature called automatic dirty checking. Suppose the following

public class Person {

    private String name;
    private Integer age;

}


public class PersonServiceImpl implements PersonService {

    public void changeAge(Integer personId, Integer newAge) {
        Person person = em.getReference(Person.class, personId);

        // person is a proxy
        person.setAge(newAge);
    }

}

If i call find method, JPA provider, behind the scenes, will call

SELECT NAME, AGE FROM PERSON WHERE PERSON_ID = ?

UPDATE PERSON SET AGE = ? WHERE PERSON_ID = ?

If i call getReference method, JPA provider, behind the scenes, will call

UPDATE PERSON SET AGE = ? WHERE PERSON_ID = ?

And you know why ???

When you call getReference, you will get a proxy object. Something like this one (JPA provider takes care of implementing this proxy)

public class PersonProxy {

    // JPA provider sets up this field when you call getReference
    private Integer personId;

    private String query = "UPDATE PERSON SET ";

    private boolean stateChanged = false;

    public void setAge(Integer newAge) {
        stateChanged = true;

        query += query + "AGE = " + newAge;
    }

}

So before transaction commit, JPA provider will see stateChanged flag in order to update OR NOT person entity. If no rows is updated after update statement, JPA provider will throw EntityNotFoundException according to JPA specification.

regards,

This should work:

window.onload = function() {
  document.getElementById('about').className = 'expand';
};

Or if you're using jQuery:

$(function() {
  $('#about').addClass('expand');
});

It is now also possible to use the native module util to promisify regular sync functions.

const { promisify } = require('util')
const sleep = promisify(setTimeout)

module.exports = () => {
  await someAsyncFunction()
  await sleep(2000)
  console.log('2 seconds later...')
}

Thanks to this question (and answers), I discovered an easy way to get at the exact NumberFormat string for virtually any format that Excel has to offer.

How to Obtain the NumberFormat String for Any Excel Number Format

Step 1: In the user interface, set a cell to the NumberFormat you want to use.

In my example, I selected the Chinese (PRC) Currency from the options contained in the "Account Numbers Format" combo box.

Step 2: Expand the Number Format dropdown and select "More Number Formats...".

Step 3: In the Number tab, in Category, click "Custom".

The "Sample" section shows the Chinese (PRC) currency formatting that I applied.

The "Type" input box contains the NumberFormat string that you can use programmatically.

So, in this example, the NumberFormat of my Chinese (PRC) Currency cell is as follows:

_ [$¥-804]* #,##0.00_ ;_ [$¥-804]* -#,##0.00_ ;_ [$¥-804]* "-"??_ ;_ @_ 

If you do these steps for each NumberFormat that you desire, then the world is yours.

I hope this helps.

HTML5 Placeholder Attribute

You are likely wanting placeholder functionality:

<input name="Name" placeholder="Enter Your Name" />

Polyfill for Older Browsers

This will not work in some older browsers, but polyfills exist (some require jQuery, others don't) to patch that functionality.

"Screw it, I'll do it myself."

If you wanted to roll your own solution, you could use the onfocus and onblur events of your element to determine what its value should be:

<input name="Name" value="Enter Your Name"
       onfocus="(this.value == 'Enter Your Name') && (this.value = '')"
       onblur="(this.value == '') && (this.value = 'Enter Your Name')" />

Avoid Mixing HTML with JavaScript

You'll find that most of us aren't big fans of evaluating JavaScript from attributes like onblur and onfocus. Instead, it's more commonly encouraged to bind this logic up purely with JavaScript. Granted, it's a bit more verbose, but it keeps a nice separation between your logic and your markup:

var nameElement = document.forms.myForm.Name;

function nameFocus( e ) {
  var element = e.target || window.event.srcElement;
  if (element.value == "Enter Your Name") element.value = "";
}

function nameBlur( e ) {
  var element = e.target || window.event.srcElement;
  if (element.value == "") element.value = "Enter Your Name";
}

if ( nameElement.addEventListener ) {
  nameElement.addEventListener("focus", nameFocus, false);
  nameElement.addEventListener("blur", nameBlur, false);
} else if ( nameElement.attachEvent ) {
  nameElement.attachEvent("onfocus", nameFocus);
  nameElement.attachEvent("onblur", nameBlur);
}

Demo: http://jsbin.com/azehum/2/edit

checked :

public Constructor(Class<E> c, int length) {

    elements = (E[]) Array.newInstance(c, length);
}

or unchecked :

public Constructor(int s) {
    elements = new Object[s];
}

PHP does have authentication on the mail-command!

The following is working for me on WAMPSERVER (windows, php 5.2.17)

php.ini

[mail function]
; For Win32 only.
SMTP = mail.yourserver.com
smtp_port = 25
auth_username = smtp-username
auth_password = smtp-password
sendmail_from = [email protected]

I've found that the following works if you're not using jQuery and only interested in cloning simple objects (see comments).

JSON.parse(JSON.stringify(json_original));

Sometimes it is not eligible to set height to pixel values. However, it is possible to show vertical scrollbar through setting height of div to 100% and overflow to auto.

Let me show an example:

<div id="content" style="height: 100%; overflow: auto">
  <p>some text</p>
  <ul>
    <li>text</li>
    .....
    <li>text</li>
</div>

I mean something like this:

FXMLLoader myLoader = null; Scene myScene = null; Stage prevStage = null;

public void start(Stage primaryStage) throws Exception {
  primaryStage.setTitle("Shop Management");
  myLoader = new FXMLLoader(getClass().getResource("cartHomePage.fxml"));
  Pane myPane = (Pane) myLoader.load();
  CartHomePageUI controller = (CartHomePageUI) myLoader.getController();
  controller.setPrevStage(primaryStage);
  myScene = new Scene(myPane);
  primaryStage.setScene(myScene);
  primaryStage.show();
}

After that

public void setPrevStage(Stage stage){
    this.prevStage = stage;
}

public void gotoCreateCategory(ActionEvent event) throws IOException {
    Stage stage = new Stage();
    stage.setTitle("Shop Management");
    myLoader = new FXMLLoader(getClass().getResource("createCategory.fxml"));
    Pane myPane = (Pane) myLoader.load();            
    Scene scene = new Scene(myPane);
    stage.setScene(scene);
// prevStage.close(); I don't think you need this, closing it will set preStage to null   put a breakpoint after this to confirm it
    setPrevStage(stage);
    stage.show();       
}

//Method to change scene when menu item create product is on click
@FXML
public void gotoCreateProduct(ActionEvent event) throws IOException {
    Stage stage = new Stage();
    stage.setTitle("Shop Management");
    myLoader = new FXMLLoader(getClass().getResource("creatProduct.fxml"));
    Pane myPane = (Pane) myLoader.load();            
    Scene scene = new Scene(myPane);
    stage.setScene(scene);
// prevStage.close(); I don't think you need this, closing it will set preStage to null put a breakpoint after this to confirm it
    setPrevStage(stage);
    stage.show();      
}

Try it and let me know please.

Is this worth mentioning?

var item = new Stack(arr).Pop();

One, albeit a clumsy option to rearrange the columns when the column order must absolutely be changed, and foreign keys are in use, is to first dump the entire database with data, then dump just the schema (pg_dump -s databasename > databasename_schema.sql). Next edit the schema file to rearrange the columns as you would like, then recreate the database from the schema, and finally restore the data into the newly created database.

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

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

There are several native solutions I've found while searching the way to check network operator.

For API >=17:

TelephonyManager manager = (TelephonyManager)context.getSystemService(Context.TELEPHONY_SERVICE);

// Get information about all radio modules on device board
// and check what you need by calling #getCellIdentity.

final List<CellInfo> allCellInfo = manager.getAllCellInfo();
for (CellInfo cellInfo : allCellInfo) {
    if (cellInfo instanceof CellInfoGsm) {
        CellIdentityGsm cellIdentity = ((CellInfoGsm) cellInfo).getCellIdentity();
        //TODO Use cellIdentity to check MCC/MNC code, for instance.
    } else if (cellInfo instanceof CellInfoWcdma) {
        CellIdentityWcdma cellIdentity = ((CellInfoWcdma) cellInfo).getCellIdentity();
    } else if (cellInfo instanceof CellInfoLte) {
        CellIdentityLte cellIdentity = ((CellInfoLte) cellInfo).getCellIdentity();
    } else if (cellInfo instanceof CellInfoCdma) {
        CellIdentityCdma cellIdentity = ((CellInfoCdma) cellInfo).getCellIdentity();
    } 
}

In AndroidManifest add permission:

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

To get network operator you can check mcc and mnc codes:

• https://en.wikipedia.org/wiki/Mobile_country_code (general information).
• https://clients.txtnation.com/hc/en-us/articles/218719768-MCCMNC-mobile-country-code-and-mobile-network-code-list- (quite full and quite latest list of operators).

For API >=22:

final SubscriptionManager subscriptionManager = SubscriptionManager.from(context);
final List<SubscriptionInfo> activeSubscriptionInfoList = subscriptionManager.getActiveSubscriptionInfoList();
for (SubscriptionInfo subscriptionInfo : activeSubscriptionInfoList) {
    final CharSequence carrierName = subscriptionInfo.getCarrierName();
    final CharSequence displayName = subscriptionInfo.getDisplayName();
    final int mcc = subscriptionInfo.getMcc();
    final int mnc = subscriptionInfo.getMnc();
    final String subscriptionInfoNumber = subscriptionInfo.getNumber();
}

For API >=23. To just check if phone is dual/triple/many sim:

TelephonyManager manager = (TelephonyManager)context.getSystemService(Context.TELEPHONY_SERVICE);
if (manager.getPhoneCount() == 2) {
    // Dual sim
}

As of Spring 5.2.4 (Spring Boot v2.2.6.RELEASE) PathMatchConfigurer.setUseSuffixPatternMatch and ContentNegotiationConfigurer.favorPathExtension have been deprecated ( https://spring.io/blog/2020/03/24/spring-framework-5-2-5-available-now and https://github.com/spring-projects/spring-framework/issues/24179).

The real problem is that the client requests a specific media type (like .com) and Spring added all those media types by default. In most cases your REST controller will only produce JSON so it will not support the requested output format (.com). To overcome this issue you should be all good by updating your rest controller (or specific method) to support the 'ouput' format (@RequestMapping(produces = MediaType.ALL_VALUE)) and of course allow characters like a dot ({username:.+}).

Example:

@RequestMapping(value = USERNAME, consumes = MediaType.APPLICATION_JSON_VALUE, produces = MediaType.APPLICATION_JSON_VALUE)
public class UsernameAPI {

    private final UsernameService service;

    @GetMapping(value = "/{username:.+}", consumes = MediaType.APPLICATION_JSON_VALUE, produces = MediaType.ALL_VALUE)
    public ResponseEntity isUsernameAlreadyInUse(@PathVariable(value = "username") @Valid @Size(max = 255) String username) {
        log.debug("Check if username already exists");
        if (service.doesUsernameExist(username)) {
            return ResponseEntity.status(HttpStatus.NO_CONTENT).build();
        }
        return ResponseEntity.notFound().build();
    }
}

Spring 5.3 and above will only match registered suffixes (media types).

elementToBeClickable is used for checking an element is visible and enabled such that you can click it.

ExpectedConditions.elementToBeClickable returns WebElement if expected condition is true otherwise it will throw TimeoutException, It never returns null.

So if your using ExpectedConditions.elementToBeClickable to find an element which will always gives you the clickable element, so no need to check for null condition, you should try as below :-

WebDriverWait wait = new WebDriverWait(Scenario1Test.driver, 10); 
WebElement element = wait.until(ExpectedConditions.elementToBeClickable(By.xpath("(//div[@id='brandSlider']/div[1]/div/div/div/img)[50]")));
element.click();

As you are saying element.click() passes both on link and label that's doesn't mean element is not clickable, it means returned element clicked but may be there is no event performs on element by click action.

Note:- I'm suggesting you always try first to find elements by id, name, className and other locator. if you faced some difficulty to find then use cssSelector and always give last priority to xpath locator because it is slower than other locator to locate an element.

Hope it helps you..:)

I know this was originally asked back in 2008, but there are some new functions that were introduced with SQL Server 2012. The FORMAT function simplifies padding left with zeros nicely. It will also perform the conversion for you:

declare @n as int = 2
select FORMAT(@n, 'd10') as padWithZeros

Update:

I wanted to test the actual efficiency of the FORMAT function myself. I was quite surprised to find the efficiency was not very good compared to the original answer from AlexCuse. Although I find the FORMAT function cleaner, it is not very efficient in terms of execution time. The Tally table I used has 64,000 records. Kudos to Martin Smith for pointing out execution time efficiency.

SET STATISTICS TIME ON
select FORMAT(N, 'd10') as padWithZeros from Tally
SET STATISTICS TIME OFF

SQL Server Execution Times: CPU time = 2157 ms, elapsed time = 2696 ms.

SET STATISTICS TIME ON
select right('0000000000'+ rtrim(cast(N as varchar(5))), 10) from Tally
SET STATISTICS TIME OFF

SQL Server Execution Times:

CPU time = 31 ms, elapsed time = 235 ms.

DateTime.remove({}, callback) The empty object will match all of them.

Follow these simple steps to obtain reference to current executing script block:

1. Put some random unique string within the script block (must be unique / different in each script block)
2. Iterate result of document.getElementsByTagName('script'), looking the unique string from each of their content (obtained from innerText/textContent property).

Example (ABCDE345678 is the unique ID):

<script type="text/javascript">
var A=document.getElementsByTagName('script'),i=count(A),thi$;
for(;i;thi$=A[--i])
  if((thi$.innerText||thi$.textContent).indexOf('ABCDE345678'))break;
// Now thi$ is refer to current script block
</script>

btw, for your case, you can simply use old fashioned document.write() method to include another script. As you mentioned that DOM is not rendered yet, you can take advantage from the fact that browser always execute script in linear sequence (except for deferred one that will be rendered later), so the rest of your document is still "not exists". Anything you write through document.write() will be placed right after the caller script.

Example of original HTML page:

<!doctype html>
<html><head>
<script src="script.js"></script>
<script src="otherscript.js"></script>
<body>anything</body></html>

Content of script.js:

document.write('<script src="inserted.js"></script>');

After rendered, the DOM structure will become:

HEAD
  SCRIPT script.js
  SCRIPT inserted.js
  SCRIPT otherscript.js
BODY

In newer versions of Git for Windows, Bash is started with --login which causes Bash to not read .bashrc directly. Instead it reads .bash_profile.

If this file does not exist, create it with the following content:

if [ -f ~/.bashrc ]; then . ~/.bashrc; fi

This will cause Bash to read the .bashrc file. From my understanding of this issue, Git for Windows should do this automatically. However, I just installed version 2.5.1, and it did not.

You can do this with Jinja's tojson filter, which

Dumps a structure to JSON so that it’s safe to use in <script> tags [and] in any place in HTML with the notable exception of double quoted attributes.

For example, in your Python, write:

some_template.render(list_of_items=list_of_items)

... or, in the context of a Flask endpoint:

return render_template('your_template.html', list_of_items=list_of_items)

Then in your template, write this:

{% for item in list_of_items %}
<span onclick='somefunction({{item | tojson}})'>{{item}}</span><br>
{% endfor %}

(Note that the onclick attribute is single-quoted. This is necessary since |tojson escapes ' characters but not " characters in its output, meaning that it can be safely used in single-quoted HTML attributes but not double-quoted ones.)

Or, to use list_of_items in an inline script instead of an HTML attribute, write this:

<script>
const jsArrayOfItems = {{list_of_items | tojson}};
// ... do something with jsArrayOfItems in JavaScript ...
</script>

DON'T use json.dumps to JSON-encode variables in your Python code and pass the resulting JSON text to your template. This will produce incorrect output for some string values, and will expose you to XSS if you're trying to encode user-provided values. This is because Python's built-in json.dumps doesn't escape characters like < and > (which need escaping to safely template values into inline <script>s, as noted at https://html.spec.whatwg.org/multipage/scripting.html#restrictions-for-contents-of-script-elements) or single quotes (which need escaping to safely template values into single-quoted HTML attributes).

If you're using Flask, note that Flask injects a custom tojson filter instead of using Jinja's version. However, everything written above still applies. The two versions behave almost identically; Flask's just allows for some app-specific configuration that isn't available in Jinja's version.

This seems to be a comprehensive, modern solution:

https://github.com/matthewhudson/device.js

It detects several platforms, smartphone vs. tablets, and orientation. It also adds classes to the BODY tag so detection takes place only once and you can read what device you're on with a simple series of jQuery hasClass functions.

I have the same error, please go to

xampp\phpMyAdmin\libraries\config.default.php

Look for : $cfg['ExecTimeLimit'] = 600;

You can change '600' to any higher value, like '6000'.

Maximum execution time in seconds is (0 for no limit).

This will fix your error.

You probably redefined your "sum" function to be an integer data type. So it is rightly telling you that an integer is not something you can pass a range.

To fix this, restart your interpreter.

Python 2.7.3 (default, Apr 20 2012, 22:44:07) 
[GCC 4.6.3] on linux2

>>> data3 = list(set(data1 + data2)) # makes new list without duplicates
>>> total = sum(data3) # calculate sum of data3 list's elements
>>> print total
233168

If you shadow the sum builtin, you can get the error you are seeing

>>> sum = 0
>>> total = sum(data3) # calculate sum of data3 list's elements
Traceback (most recent call last):

Also, note that sum will work fine on the set there is no need to convert it to a list

In Sass we can write:

background-color: rgba(#ff0000, 0.5);

as it was suggested in Hex representation of a color with alpha channel?

This a old question, but this can useful for someone In my case i can't using a sub query because i have a big query and i need using min() on my result, if i use sub query the db need reexecute my big query. i'm using Mysql

select t.* 
    from (select m.*, @g := 0
        from MyTable m --here i have a big query
        order by id, record_date) t
    where (1 = case when @g = 0 or @g <> id then 1 else  0 end )
          and (@g := id) IS NOT NULL

Basically I ordered the result and then put a variable in order to get only the first record in each group.

I think you want to specify

-H "Content-Type:text/xml"

with a colon, not an equals.

Game marketing is a commercial process; publishers want quantifiable low-risk returns on their investment. As a consequence, the focus is usually on technology gimmicks (with exceptions) that consumers will buy to produce reliable return - these tend to be superficial visual effects such as lens glare or higher resolution. These effects are reliable because they simply use increases in processing power - they exploit the hardware/Moore's law increases. this implies using C/C++ - java is usually too abstracted from the hardware to exploit these benefits.

There's a shorthand-type way to do this that I have been using recently. This might need to be configured, but it should work in most mainline PHP installations. If you're storing the link in a PHP variable, you can do it in the following manner based off the OP:

<html>
  <body>
    <?php
      $link = "http://www.google.com";
    ?>
    <a href="<?= $link ?>">Click here to go to Google.</a>
  </body>
</html>

This will evaluate the variable as a string, in essence shorthand for echo $link;

Try this.

<asp:Button id="myButton" runat="server" style="display:none" Text="Click Me" />

<script type="text/javascript">
    function ShowButton() {
        var buttonID = '<%= myButton.ClientID %>';
        var button = document.getElementById(buttonID);
        if(button) { button.style.display = 'inherit'; }
    }
</script>

Don't use server-side code to do this because that would require a postback. Instead of using Visibility="false", you can just set a CSS property that hides the button. Then, in javascript, switch that property back whenever you want to show the button again.

The ClientID is used because it can be different from the server ID if the button is inside a Naming Container control. These include Panels of various sorts.

You can convert any thing to anything using this function:

template<class T = std::string, class U>
T to(U a) {
    std::stringstream ss;
    T ret;
    ss << a;
    ss >> ret;
    return ret;
};

usage :

std::string str = to(2.5);
double d = to<double>("2.5");

In object oriented design, the amount of coupling refers to how much the design of one class depends on the design of another class. In other words, how often do changes in class A force related changes in class B? Tight coupling means the two classes often change together, loose coupling means they are mostly independent. In general, loose coupling is recommended because it's easier to test and maintain.

Using just try_files didn't work for me - it caused a rewrite or internal redirection cycle error in my logs.

The Nginx docs had some additional details:

http://nginx.org/en/docs/http/ngx_http_core_module.html#try_files

So I ended up using the following:

root /var/www/mysite;

location / {
    try_files $uri /base.html;
}

location = /base.html {
    expires 30s;
}

You use something like

from flask import send_file

@app.route('/get_image')
def get_image():
    if request.args.get('type') == '1':
       filename = 'ok.gif'
    else:
       filename = 'error.gif'
    return send_file(filename, mimetype='image/gif')

to send back ok.gif or error.gif, depending on the type query parameter. See the documentation for the send_file function and the request object for more information.

You can use:

if (parentGuest.nextSibling) {
  parentGuest.parentNode.insertBefore(childGuest, parentGuest.nextSibling);
}
else {
  parentGuest.parentNode.appendChild(childGuest);
}

But as Pavel pointed out, the referenceElement can be null/undefined, and if so, insertBefore behaves just like appendChild. So the following is equivalent to the above:

parentGuest.parentNode.insertBefore(childGuest, parentGuest.nextSibling);

class someclass:
        x=1
        y=2
        z=3
        def __init__(self):
           self.current_idx = 0
           self.items = ["x","y","z"]
        def next(self):
            if self.current_idx < len(self.items):
                self.current_idx += 1
                k = self.items[self.current_idx-1]
                return (k,getattr(self,k))
            else:
                raise StopIteration
        def __iter__(self):
           return self

then just call it as an iterable

s=someclass()
for k,v in s:
    print k,"=",v

All XAMPP packages come with Multibyte String (php_mbstring.dll) extension installed.

If you have accidentally removed DLL file from php/ext folder, just add it back (get the copy from XAMPP zip archive - its downloadable).

If you have deleted the accompanying INI configuration line from php.ini file, add it back as well:

extension=php_mbstring.dll

Also, ensure to restart your webserver (Apache) using XAMPP control panel.

Additional Info on Enabling PHP Extensions

• install extension (e.g. put php_mbstring.dll into /XAMPP/php/ext directory)
• in php.ini, ensure extension directory specified (e.g. extension_dir = "ext")
• ensure correct build of DLL file (e.g. 32bit thread-safe VC9 only works with DLL files built using exact same tools and configuration: 32bit thread-safe VC9)
• ensure PHP API versions match (If not, once you restart the webserver you will receive related error.)

For me, the problem was incorrect content type of the served .css file (if it included certain unicode characters).

Changing the content-type to text/css solved the problem.

Have you tried setting the text-indent property to something like -999em? That's a good way to 'hide' text.

Or you can set the font-size to 0, which would work too.

I just made all requests JSONP because it was the only solution for all of our supported browsers (IE7+ and the regulars). Mind you, your answer technically works for IE9 so you have the correct answer.

For Mac Users who using Eclipse Use Cmd + I(Indent) and Cmd + F(Format). But I had worst experience with Cmd + F which breaks the code in to several lines as follows

String A = MyClass.getA(x, y);
if (A != null) {
    A = Long.parseLong(0);
}

Where my original code is as follows

String A = MyClass.get(x, y);
if (A != null) {
    A = Long.parseLong(0);
}

Be sure that android:debuggable="true" is set in the application tag of your manifest file, and then:

1. Plug your phone into your computer and enable USB debugging on the phone
2. Open eclipse and a workspace containing the code for your app
3. In Eclipse, go to Window->Show View->Devices
4. Look at the Devices view which should now be visible, you should see your device listed
5. If your device isn't listed, you'll have to track down the ADB drivers for your phone before continuing
6. If you want to step through code, set a breakpoint somewhere in your app
7. Open the app on your phone
8. In the Devices view, expand the entry for your phone if it isn't already expanded, and look for your app's package name.
9. Click on the package name, and in the top right of the Devices view you should see a green bug along with a number of other small buttons. Click the green bug.
10. You should now be attached/debugging your app.

Try using date and time functions (MONTH(), YEAR(), DAY(), MySQL Manual)

Just in case if someone is wondering to save the CSV file to a specific path for email attachments. Then it can be done as follows

I know I have added a lot of comments just for newbies :)

I have added an example so that you can summarize well.

$activeUsers = /** Query to get the active users */

/** Following is the Variable to store the Users data as 
    CSV string with newline character delimiter, 

    its good idea of check the delimiter based on operating system */

$userCSVData = "Name,Email,CreatedAt\n";

/** Looping the users and appending to my earlier csv data variable */
foreach ( $activeUsers as $user ) {
    $userCSVData .= $user->name. "," . $user->email. "," . $user->created_at."\n";
}
/** Here you can use with H:i:s too. But I really dont care of my old file  */
$todayDate  = date('Y-m-d');
/** Create Filname and Path to Store */
$fileName   = 'Active Users '.$todayDate.'.csv';
$filePath   = public_path('uploads/'.$fileName); //I am using laravel helper, in case if your not using laravel then just add absolute or relative path as per your requirements and path to store the file

/** Just in case if I run the script multiple time 
    I want to remove the old file and add new file.

    And before deleting the file from the location I am making sure it exists */
if(file_exists($filePath)){
    unlink($filePath);
}
$fp = fopen($filePath, 'w+');
fwrite($fp, $userCSVData); /** Once the data is written it will be saved in the path given */
fclose($fp);

/** Now you can send email with attachments from the $filePath */

NOTE: The following is a very bad idea to increase the memory_limit and time limit, but I have only added to make sure if anyone faces the problem of connection time out or any other. Make sure to find out some alternative before sticking to it.

You have to add the following at the start of the above script.

ini_set("memory_limit", "10056M");
set_time_limit(0);
ini_set('mysql.connect_timeout', '0');
ini_set('max_execution_time', '0');

If you are a user of the free Visual Studio Express edition the right key is in

HKEY_CURRENT_USER\Software\Microsoft\VCExpress\9.0\Text Editor

{note the VCExpress instead of VisualStudio) but it works! :)

To get rid of error:

Type '"text"' is not assignable to type '"json"'.

Use

responseType: 'text' as 'json'

import { HttpClient, HttpHeaders } from '@angular/common/http';
.....
 return this.http
        .post<string>(
            this.baseUrl + '/Tickets/getTicket',
            JSON.stringify(value),
        { headers, responseType: 'text' as 'json' }
        )
        .map(res => {
            return res;
        })
        .catch(this.handleError);

In your Manifest define windowSoftInputMode property:

<activity android:name=".MyActivity"
          android:windowSoftInputMode="adjustNothing">

There's no good substitute to testing on an actual device.

Real devices have higher display densities, meaning that pixels are smaller. If you don't test on a real device, you may not realise that your design includes text that is too small to read or buttons that are too small to tap.

You use real devices with your fingers, not a mouse. This means that the accuracy of your taps is much lower and what you are tapping is obscured by your finger. If you don't test on a real device, you may not realise you've introduced usability problems into your design.

I just wrote my little subclass of UIView that has ability to produce native iOS 7 blur on any custom view. It uses UIToolbar but in a safe way for changing it's frame, bounds, color and alpha with real-time animation.

There are two ways to split strings over multiple lines:

Using \

All lines in C can be split into multiple lines using \.

Plain C:

char *my_string = "Line 1 \
                   Line 2";

Objective-C:

NSString *my_string = @"Line1 \
                        Line2";

Better approach

There's a better approach that works just for strings.

Plain C:

char *my_string = "Line 1 "
                  "Line 2";

Objective-C:

NSString *my_string = @"Line1 "
                       "Line2";    // the second @ is optional

The second approach is better, because there isn't a lot of whitespace included. For a SQL query however, both are possible.

NOTE: With a #define, you have to add an extra '\' to concatenate the two strings:

Plain C:

#define kMyString "Line 1"\
                  "Line 2"

It's better (but wordier) to use:

var element = document.getElementById('something');
if (element != null && element.value == '') {
}

Please note, the first version of my answer was wrong:

var element = document.getElementById('something');
if (typeof element !== "undefined" && element.value == '') {
}

because getElementById() always return an object (null object if not found) and checking for"undefined" would never return a false, as typeof null !== "undefined" is still true.

Were you trying it like this:

string text = GetTextFromSomewhere();
text.Replace("\\", "");
text.Replace("\"", "");

? If so, that's the problem - Replace doesn't change the original string, it returns a new string with the replacement performed... so you'd want:

string text = GetTextFromSomewhere();
text = text.Replace("\\", "").Replace("\"", "");

Note that this will replace each backslash and each double-quote character; if you only wanted to replace the pair "backslash followed by double-quote" you'd just use:

string text = GetTextFromSomewhere();
text = text.Replace("\\\"", "");

(As mentioned in the comments, this is because strings are immutable in .NET - once you've got a string object somehow, that string will always have the same contents. You can assign a reference to a different string to a variable of course, but that's not actually changing the contents of the existing string.)

This worked for me:

.carousel-control-prev-icon {
        background-image: url("data:image/svg+xml,%3csvg xmlns='http://www.w3.org/2000/svg' fill='%23000' width='8' height='8' viewBox='0 0 8 8'%3e%3cpath d='M5.25 0l-4 4 4 4 1.5-1.5L4.25 4l2.5-2.5L5.25 0z'/%3e%3c/svg%3e");
      }
      
      .carousel-control-next-icon {
        background-image: url("data:image/svg+xml,%3csvg xmlns='http://www.w3.org/2000/svg' fill='%23000' width='8' height='8' viewBox='0 0 8 8'%3e%3cpath d='M2.75 0l-1.5 1.5L3.75 4l-2.5 2.5L2.75 8l4-4-4-4z'/%3e%3c/svg%3e");
      }

I changed the color in the url of the icon. Thats the original that is used in the bootstrap page but with this section in black:

"...fill='%23000'..."

$("#myid").dialog({height:"auto",
        width:"auto",
        show: {effect: 'fade', speed: 1000},
        hide: {effect: 'fade', speed: 1000},
        open: function( event, ui ) {
          $("#myid").closest("div[role='dialog']").css({top:100,left:100});              
         }
    });

As the other answers have indicated, you need to use an anonymous type.

As far as syntax is concerned, I personally far prefer method chaining. The method chaining equivalent would be:-

var employee = _db.EMPLOYEEs
    .Where(x => x.EMAIL == givenInfo || x.USER_NAME == givenInfo)
    .Select(x => new { x.EMAIL, x.ID });

AFAIK, the declarative LINQ syntax is converted to a method call chain similar to this when it is compiled.

UPDATE

If you want the entire object, then you just have to omit the call to Select(), i.e.

var employee = _db.EMPLOYEEs
    .Where(x => x.EMAIL == givenInfo || x.USER_NAME == givenInfo);

The international versions:

        Dim retval As Double
        Dim sep As String = CultureInfo.CurrentCulture.NumberFormat.NumberDecimalSeparator

        Return retval

If you're like me you just want to modify some of the colors in AppCompat, and the only color you need to uniquely change in the dialog is the background. Then all you need to do is set a color for colorBackgroundFloating.

Here's my basic theme that simply modifies some colors with no nested themes:

    <style name="AppTheme" parent="Theme.AppCompat">
        <item name="colorPrimary">@color/theme_colorPrimary</item>
        <item name="colorPrimaryDark">@color/theme_colorPrimaryDark</item>
        <item name="colorAccent">@color/theme_colorAccent</item>
        <item name="colorControlActivated">@color/theme_colorControlActivated</item>
        <item name="android:windowBackground">@color/theme_bg</item>
        <item name="colorBackgroundFloating">@color/theme_dialog_bg</item><!-- Dialog background color -->
        <item name="colorButtonNormal">@color/theme_colorPrimary</item>
        <item name="colorControlHighlight">@color/theme_colorAccent</item>
    </style>

I encountered this issue.

Discovered that somewhere in my code I was asking it to count starting from 0 (as you would in a C# code).

Turns out Excel counting starts at 1.

You can clone a job:

1. Click on 'New Item' link
2. Give a new name for your job
3. Select radio button 'Copy existing Item'
4. Give the job name that you want to clone
5. Click 'OK'

Finally, you have your new job, which reflects all features of your cloned one.

No.

You can achieve the same behavior by passing an Object which has smart defaults. But again it depends what your case is at hand.

Use the password_verify() function

if (password_vertify($inputpassword, $row['password'])) {
  print "Logged in";
else {
    print "Password Incorrect";
}

INSERT syntax cannot have WHERE clause. The only time you will find INSERT has WHERE clause is when you are using INSERT INTO...SELECT statement.

The first syntax is already correct.

You must have added new files in your commits which has not been pushed. Check the file and push that file again and the try pull / push it will work. This worked for me..

Update

Now that the question scope has been corrected, I might add something in this regard as well:

There are many comparisons between Apache Solr and ElasticSearch available, so I'll reference those I found most useful myself, i.e. covering the most important aspects:

• Bob Yoplait already linked kimchy's answer to ElasticSearch, Sphinx, Lucene, Solr, Xapian. Which fits for which usage?, which summarizes the reasons why he went ahead and created ElasticSearch, which in his opinion provides a much superior distributed model and ease of use in comparison to Solr.

• Ryan Sonnek's Realtime Search: Solr vs Elasticsearch provides an insightful analysis/comparison and explains why he switched from Solr to ElasticSeach, despite being a happy Solr user already - he summarizes this as follows:

  Solr may be the weapon of choice when building standard search applications, but Elasticsearch takes it to the next level with an architecture for creating modern realtime search applications. Percolation is an exciting and innovative feature that singlehandedly blows Solr right out of the water. Elasticsearch is scalable, speedy and a dream to integrate with. Adios Solr, it was nice knowing you. [emphasis mine]

• The Wikipedia article on ElasticSearch quotes a comparison from the reputed German iX magazine, listing advantages and disadvantages, which pretty much summarize what has been said above already:

  Advantages:

  • ElasticSearch is distributed. No separate project required. Replicas are near real-time too, which is called "Push replication".
  • ElasticSearch fully supports the near real-time search of Apache Lucene.
  • Handling multitenancy is not a special configuration, where with Solr a more advanced setup is necessary.
  • ElasticSearch introduces the concept of the Gateway, which makes full backups easier.

  Disadvantages:

  • Only one main developer [not applicable anymore according to the current elasticsearch GitHub organization, besides having a pretty active committer base in the first place]
  • No autowarming feature [not applicable anymore according to the new Index Warmup API]

Initial Answer

They are completely different technologies addressing completely different use cases, thus cannot be compared at all in any meaningful way:

• Apache Solr - Apache Solr offers Lucene's capabilities in an easy to use, fast search server with additional features like faceting, scalability and much more

• Amazon ElastiCache - Amazon ElastiCache is a web service that makes it easy to deploy, operate, and scale an in-memory cache in the cloud.

  • Please note that Amazon ElastiCache is protocol-compliant with Memcached, a widely adopted memory object caching system, so code, applications, and popular tools that you use today with existing Memcached environments will work seamlessly with the service (see Memcached for details).

[emphasis mine]

Maybe this has been confused with the following two related technologies one way or another:

• ElasticSearch - It is an Open Source (Apache 2), Distributed, RESTful, Search Engine built on top of Apache Lucene.

• Amazon CloudSearch - Amazon CloudSearch is a fully-managed search service in the cloud that allows customers to easily integrate fast and highly scalable search functionality into their applications.

The Solr and ElasticSearch offerings sound strikingly similar at first sight, and both use the same backend search engine, namely Apache Lucene.

While Solr is older, quite versatile and mature and widely used accordingly, ElasticSearch has been developed specifically to address Solr shortcomings with scalability requirements in modern cloud environments, which are hard(er) to address with Solr.

As such it would probably be most useful to compare ElasticSearch with the recently introduced Amazon CloudSearch (see the introductory post Start Searching in One Hour for Less Than $100 / Month), because both claim to cover the same use cases in principle.

not need to run queries to sidable FKs on sql. If you have a FK from table A to B, you should:

• delete data from table A
• delete data from table B
• insert data on B
• insert data on A

You can also tell the destination not to check constraints

$("#form").submit(function() { $("#saveButton").attr("disabled", true); });

not a best answer but works for me.

There is an even easier way that does not involve writing anything in the code behind: Just add this line to your javascript:

if(<%=(Not Page.IsPostBack).ToString().ToLower()%>){//Your JavaScript goodies here}

or

if(<%=(Page.IsPostBack).ToString().ToLower()%>){//Your JavaScript goodies here}

'1.43'.replace('.','',1).isdigit()

which will return true only if there is one or no '.' in the string of digits.

'1.4.3'.replace('.','',1).isdigit()

will return false

'1.ww'.replace('.','',1).isdigit()

will return false

Running ps -e does the trick. Found the answer here.

If you are willing to put a container element around your image, a pure CSS solution is simple. You see, 99% height has no meaning when the parent element will extend vertically to contain its children. The parent needs to have a fixed height, say... the height of the viewport.

HTML

<!-- use a tall image to illustrate the problem -->
<div class='fill-screen'>
    <img class='make-it-fit' 
         src='https://upload.wikimedia.org/wikipedia/commons/f/f2/Leaning_Tower_of_Pisa.jpg'>
</div>

CSS

div.fill-screen {
    position: fixed;
    left: 0;
    right: 0;
    top: 0;
    bottom: 0;
    text-align: center;
}

img.make-it-fit {
    max-width: 99%;
    max-height: 99%;
}

Play with the fiddle.

I was unable to make use of the most popular answer because the --batch-check command-line switch to Git 1.8.3 (that I have to use) does not accept any arguments. The ensuing steps have been tried on CentOS 6.5 with Bash 4.1.2

Key Concepts

In Git, the term blob implies the contents of a file. Note that a commit might change the contents of a file or pathname. Thus, the same file could refer to a different blob depending on the commit. A certain file could be the biggest in the directory hierarchy in one commit, while not in another. Therefore, the question of finding large commits instead of large files, puts matters in the correct perspective.

For The Impatient

Command to print the list of blobs in descending order of size is:

git cat-file --batch-check < <(git rev-list --all --objects  | \
awk '{print $1}')  | grep blob  | sort -n -r -k 3

Sample output:

3a51a45e12d4aedcad53d3a0d4cf42079c62958e blob 305971200
7c357f2c2a7b33f939f9b7125b155adbd7890be2 blob 289163620

To remove such blobs, use the BFG Repo Cleaner, as mentioned in other answers. Given a file blobs.txt that just contains the blob hashes, for example:

3a51a45e12d4aedcad53d3a0d4cf42079c62958e
7c357f2c2a7b33f939f9b7125b155adbd7890be2

Do:

java -jar bfg.jar -bi blobs.txt <repo_dir>

The question is about finding the commits, which is more work than finding blobs. To know, please read on.

Further Work

Given a commit hash, a command that prints hashes of all objects associated with it, including blobs, is:

git ls-tree -r --full-tree <commit_hash>

So, if we have such outputs available for all commits in the repo, then given a blob hash, the bunch of commits are the ones that match any of the outputs. This idea is encoded in the following script:

#!/bin/bash
DB_DIR='trees-db'

find_commit() {
    cd ${DB_DIR}
    for f in *; do
        if grep -q $1 ${f}; then
            echo ${f}
        fi
    done
    cd - > /dev/null
}

create_db() {
    local tfile='/tmp/commits.txt'
    mkdir -p ${DB_DIR} && cd ${DB_DIR}
    git rev-list --all > ${tfile}

    while read commit_hash; do
        if [[ ! -e ${commit_hash} ]]; then
            git ls-tree -r --full-tree ${commit_hash} > ${commit_hash}
        fi
    done < ${tfile}
    cd - > /dev/null
    rm -f ${tfile}
}

create_db

while read id; do
    find_commit ${id};
done

If the contents are saved in a file named find-commits.sh then a typical invocation will be as under:

cat blobs.txt | find-commits.sh

As earlier, the file blobs.txt lists blob hashes, one per line. The create_db() function saves a cache of all commit listings in a sub-directory in the current directory.

Some stats from my experiments on a system with two Intel(R) Xeon(R) CPU E5-2620 2.00GHz processors presented by the OS as 24 virtual cores:

• Total number of commits in the repo = almost 11,000
• File creation speed = 126 files/s. The script creates a single file per commit. This occurs only when the cache is being created for the first time.
• Cache creation overhead = 87 s.
• Average search speed = 522 commits/s. The cache optimization resulted in 80% reduction in running time.

Note that the script is single threaded. Therefore, only one core would be used at any one time.

string is an alias for String in the .NET Framework.

Where "String" is in fact System.String.

I would say that they are interchangeable and there is no difference when and where you should use one or the other.

It would be better to be consistent with which one you did use though.

For what it's worth, I use string to declare types - variables, properties, return values and parameters. This is consistent with the use of other system types - int, bool, var etc (although Int32 and Boolean are also correct).

I use String when using the static methods on the String class, like String.Split() or String.IsNullOrEmpty(). I feel that this makes more sense because the methods belong to a class, and it is consistent with how I use other static methods.

You must make sure your requests module is not being installed in a more recent version of python.

When using python 3.7, run your python file like:

python3 myfile.py

or enter python interactive mode with:

python3

Yes, this works for me. Run your file like this: python3 file.py

You can run something like this:

sqlcmd -S MyServer -d myDB -E -Q "select col1, col2, col3 from SomeTable" 
       -o "MyData.csv" -h-1 -s"," -w 700

• -h-1 removes column name headers from the result
  
• -s"," sets the column seperator to ,
  
• -w 700 sets the row width to 700 chars (this will need to be as wide as the longest row or it will wrap to the next line)

When you choose any value from spinner, then you get selected value,

interested.getSelectedItem().toString();

var result = decimal.ToDouble(decimal.Divide(5, 2));

Adding this because nobody did yet, and this seems to be asked for and implemented a lot with hashes, but it's always done very poorly...

This takes a string input, and a maximum number you want the hash to equal, and produces a unique number based on the string input.

You can use this to produce a unique index into an array of images (If you want to return a specific avatar for a user, chosen at random, but also chosen based on their name, so it will always be assigned to someone with that name).

You can also use this, of course, to return an index into an array of colors, like for generating unique avatar background colors based on someone's name.

function hashInt (str, max = 1000) {
    var hash = 0;
    for (var i = 0; i < str.length; i++) {
      hash = ((hash << 5) - hash) + str.charCodeAt(i);
      hash = hash & hash;
    }
    return Math.round(max * Math.abs(hash) / 2147483648);
}

I know this is a old question but lately I've been facing some similar issue while trying to decorate some React Component's methods, for debugging purposes. As people already said, arguments.caller and arguments.callee are forbidden in strict mode which is probably enabled by default in your React transpiling. You can either disable it, or I've been able to come up with another hack, because in React all class functions are named, you can actually do this:

Component.prototype.componentWillMount = function componentWillMount() {
    console.log('Callee name: ', this.__proto__.constructor.toString().substr(0,30));
...
}

You need to get the total contents size of each directory recursively to output. Also, you need to specify that the contents you're grabbing to measure are not directories, or you risk errors (as directories do not have a Length parameter).

Here's your script modified for the output you're looking for:

$colItems = Get-ChildItem $startFolder | Where-Object {$_.PSIsContainer -eq $true} | Sort-Object
foreach ($i in $colItems)
{
    $subFolderItems = Get-ChildItem $i.FullName -recurse -force | Where-Object {$_.PSIsContainer -eq $false} | Measure-Object -property Length -sum | Select-Object Sum
    $i.FullName + " -- " + "{0:N2}" -f ($subFolderItems.sum / 1MB) + " MB"
}

Using the Excel Text import wizard to import it if it is a text file, like a CSV file, is another option and can be done based on which row number to which row numbers you specify. See: This link

h2.myClass refers to all h2 with class="myClass".

.myClass h2 refers to all h2 that are children of (i.e. nested in) elements with class="myClass".

If you want the h2 in your HTML to appear blue, change the CSS to the following:

.myClass h2 {
    color: blue;
}

If you want to be able to reference that h2 by a class rather than its tag, you should leave the CSS as it is and give the h2 a class in the HTML:

<h2 class="myClass">This header should be BLUE to match the element.class selector</h2>

How's this for a work around (using an actual table)?

table {
    border-collapse: collapse;
}

tr.row {
    border-bottom: solid white 30px; /* change "white" to your background color */
}

It's not as dynamic, since you have to explicitly set the color of the border (unless there's a way around that too), but this is something I'm experimenting with on a project of my own.

Edit to include comments regarding transparent:

tr.row {
    border-bottom: 30px solid transparent;
}

The only option I have found to do this is find some exact wording and put that under the "Has the words" option. Its not the best option, but it works.

You can catch it like any other exception:

try {
  foo();
}
catch (const std::bad_alloc&) {
  return -1;
}

Quite what you can usefully do from this point is up to you, but it's definitely feasible technically.

In general you cannot, and should not try, to respond to this error. bad_alloc indicates that a resource cannot be allocated because not enough memory is available. In most scenarios your program cannot hope to cope with that, and terminating soon is the only meaningful behaviour.

Worse, modern operating systems often over-allocate: on such systems, malloc and new can return a valid pointer even if there is not enough free memory left – std::bad_alloc will never be thrown, or is at least not a reliable sign of memory exhaustion. Instead, attempts to access the allocated memory will then result in a segmentation fault, which is not catchable (you can handle the segmentation fault signal, but you cannot resume the program afterwards).

The only thing you could do when catching std::bad_alloc is to perhaps log the error, and try to ensure a safe program termination by freeing outstanding resources (but this is done automatically in the normal course of stack unwinding after the error gets thrown if the program uses RAII appropriately).

In certain cases, the program may attempt to free some memory and try again, or use secondary memory (= disk) instead of RAM but these opportunities only exist in very specific scenarios with strict conditions:

1. The application must ensure that it runs on a system that does not overcommit memory, i.e. it signals failure upon allocation rather than later.
2. The application must be able to free memory immediately, without any further accidental allocations in the meantime.

It’s exceedingly rare that applications have control over point 1 — userspace applications never do, it’s a system-wide setting that requires root permissions to change.¹

OK, so let’s assume you’ve fixed point 1. What you can now do is for instance use a LRU cache for some of your data (probably some particularly large business objects that can be regenerated or reloaded on demand). Next, you need to put the actual logic that may fail into a function that supports retry — in other words, if it gets aborted, you can just relaunch it:

lru_cache<widget> widget_cache;

double perform_operation(int widget_id) {
    std::optional<widget> maybe_widget = widget_cache.find_by_id(widget_id);
    if (not maybe_widget) {
        maybe_widget = widget_cache.store(widget_id, load_widget_from_disk(widget_id));
    }
    return maybe_widget->frobnicate();
}

…

for (int num_attempts = 0; num_attempts < MAX_NUM_ATTEMPTS; ++num_attempts) {
    try {
        return perform_operation(widget_id);
    } catch (std::bad_alloc const&) {
        if (widget_cache.empty()) throw; // memory error elsewhere.
        widget_cache.remove_oldest();
    }
}

// Handle too many failed attempts here.

But even here, using std::set_new_handler instead of handling std::bad_alloc provides the same benefit and would be much simpler.

¹ If you’re creating an application that does control point 1, and you’re reading this answer, please shoot me an email, I’m genuinely curious about your circumstances.

What is the C++ Standard specified behavior of new in c++?

The usual notion is that if new operator cannot allocate dynamic memory of the requested size, then it should throw an exception of type std::bad_alloc.
However, something more happens even before a bad_alloc exception is thrown:

C++03 Section 3.7.4.1.3: says

An allocation function that fails to allocate storage can invoke the currently installed new_handler(18.4.2.2), if any. [Note: A program-supplied allocation function can obtain the address of the currently installed new_handler using the set_new_handler function (18.4.2.3).] If an allocation function declared with an empty exception-specification (15.4), throw(), fails to allocate storage, it shall return a null pointer. Any other allocation function that fails to allocate storage shall only indicate failure by throw-ing an exception of class std::bad_alloc (18.4.2.1) or a class derived from std::bad_alloc.

Consider the following code sample:

#include <iostream>
#include <cstdlib>

// function to call if operator new can't allocate enough memory or error arises
void outOfMemHandler()
{
    std::cerr << "Unable to satisfy request for memory\n";

    std::abort();
}

int main()
{
    //set the new_handler
    std::set_new_handler(outOfMemHandler);

    //Request huge memory size, that will cause ::operator new to fail
    int *pBigDataArray = new int[100000000L];

    return 0;
}

In the above example, operator new (most likely) will be unable to allocate space for 100,000,000 integers, and the function outOfMemHandler() will be called, and the program will abort after issuing an error message.

As seen here the default behavior of new operator when unable to fulfill a memory request, is to call the new-handler function repeatedly until it can find enough memory or there is no more new handlers. In the above example, unless we call std::abort(), outOfMemHandler() would be called repeatedly. Therefore, the handler should either ensure that the next allocation succeeds, or register another handler, or register no handler, or not return (i.e. terminate the program). If there is no new handler and the allocation fails, the operator will throw an exception.

What is the new_handler and set_new_handler?

new_handler is a typedef for a pointer to a function that takes and returns nothing, and set_new_handler is a function that takes and returns a new_handler.

Something like:

typedef void (*new_handler)();
new_handler set_new_handler(new_handler p) throw();

set_new_handler's parameter is a pointer to the function operator new should call if it can't allocate the requested memory. Its return value is a pointer to the previously registered handler function, or null if there was no previous handler.

How to handle out of memory conditions in C++?

Given the behavior of newa well designed user program should handle out of memory conditions by providing a proper new_handlerwhich does one of the following:

Make more memory available: This may allow the next memory allocation attempt inside operator new's loop to succeed. One way to implement this is to allocate a large block of memory at program start-up, then release it for use in the program the first time the new-handler is invoked.

Install a different new-handler: If the current new-handler can't make any more memory available, and of there is another new-handler that can, then the current new-handler can install the other new-handler in its place (by calling set_new_handler). The next time operator new calls the new-handler function, it will get the one most recently installed.

(A variation on this theme is for a new-handler to modify its own behavior, so the next time it's invoked, it does something different. One way to achieve this is to have the new-handler modify static, namespace-specific, or global data that affects the new-handler's behavior.)

Uninstall the new-handler: This is done by passing a null pointer to set_new_handler. With no new-handler installed, operator new will throw an exception ((convertible to) std::bad_alloc) when memory allocation is unsuccessful.

Throw an exception convertible to std::bad_alloc. Such exceptions are not be caught by operator new, but will propagate to the site originating the request for memory.

Not return: By calling abort or exit.

Details on return values and their meaning

Per 3.6.1 ([basic.start.main]):

A return statement in main has the effect of leaving the main function (destroying any objects with automatic storage duration) and calling std::exit with the return value as the argument. If control reaches the end of main without encountering a return statement, the effect is that of executing

return 0;

The behavior of std::exit is detailed in section 18.5 ([support.start.term]), and describes the status code:

Finally, control is returned to the host environment. If status is zero or EXIT_SUCCESS, an implementation-defined form of the status successful termination is returned. If status is EXIT_FAILURE, an implementation-defined form of the status unsuccessful termination is returned. Otherwise the status returned is implementation-defined.

For example , a function which returns value of any parameters variable.

function GetURLParameter(sParam)
{
    var sPageURL = window.location.search.substring(1);
    var sURLVariables = sPageURL.split('&');
    for (var i = 0; i < sURLVariables.length; i++)
    {
        var sParameterName = sURLVariables[i].split('=');
        if (sParameterName[0] == sParam)
        {
            return sParameterName[1];
        }
    }
}?

And this is how you can use this function assuming the URL is,

"http://example.com/?technology=jquery&blog=jquerybyexample".

var tech = GetURLParameter('technology');
var blog = GetURLParameter('blog');

So in above code variable "tech" will have "jQuery" as value and "blog" variable's will be "jquerybyexample".

Reason of the error is wrong initialization of the mysqli object. True construction would be like this:

$DBConnect = new mysqli("localhost","root","","Ladle");

Find the project's folder in your system, enter it's Properties via context menu and deselect "Read only" option. Worked in my case.

This seems to be the source of the problem in many cases, moreover some solutions up there base on copying/rewriting the files in the project what makes them non-read-only.

You can't go through the details of the method by using the step over. If you want to skip the current line, you can use step over, then you only need to press the F6 for only once to move to the next line. And if you think there's someting wrong within the method, use F5 to examine the details.

Here is a simple answer using pandas.

import pandas as pd
list1 = ['foo', 'fob', 'faz', 'funk']
string = 'bar'

list2 = (pd.Series(list1) + string).tolist()
list2
# ['foobar', 'fobbar', 'fazbar', 'funkbar']

For the example case above, it is usually omitted, yes. However, either way is syntactically correct.

You need to use strcmp:

strcmp(namet2, nameIt2)

The answer to the question how to convert a .cer file into a .crt file (they are encoded differently!) is:

openssl pkcs7 -print_certs -in certificate.cer -out certificate.crt

You can use preg_replace in this case;

$res = preg_replace("/[^0-9]/", "", "Every 6 Months" );

$res return 6 in this case.

If want also to include decimal separator or thousand separator check this example:

$res = preg_replace("/[^0-9.]/", "", "$ 123.099");

$res returns "123.099" in this case

Include period as decimal separator or thousand separator: "/[^0-9.]/"

Include coma as decimal separator or thousand separator: "/[^0-9,]/"

Include period and coma as decimal separator and thousand separator: "/[^0-9,.]/"

https://developer.apple.com/library/content/featuredarticles/ViewControllerPGforiPhoneOS/ImplementingaContainerViewController.html#//apple_ref/doc/uid/TP40007457-CH11-SW1

This documentation has much more detailed information for every instruction and also describes how to do add transitions.

Translated to Swift 3:

func cycleFromViewController(oldVC: UIViewController,
               newVC: UIViewController) {
   // Prepare the two view controllers for the change.
   oldVC.willMove(toParentViewController: nil)
   addChildViewController(newVC)

   // Get the start frame of the new view controller and the end frame
   // for the old view controller. Both rectangles are offscreen.r
   newVC.view.frame = view.frame.offsetBy(dx: view.frame.width, dy: 0)
   let endFrame = view.frame.offsetBy(dx: -view.frame.width, dy: 0)

   // Queue up the transition animation.
   self.transition(from: oldVC, to: newVC, duration: 0.25, animations: { 
        newVC.view.frame = oldVC.view.frame
        oldVC.view.frame = endFrame
    }) { (_: Bool) in
        oldVC.removeFromParentViewController()
        newVC.didMove(toParentViewController: self)
    }
}

Does not work fully (the hr line part) on all browsers, but here is the solution:

<select name="selector">_x000D_
  <option value="1">Option 1</option>_x000D_
  <option value="2">Option 2</option>_x000D_
  <option value="3">Option 3</option>_x000D_
  <option disabled><hr></option>_x000D_
  <option value="4">Option 4</option>_x000D_
  <option value="5">Option 5</option>_x000D_
  <option value="6">Option 6</option>_x000D_
</select>

Just make a rule for each case:

<div id="homePage" ng-class="{ 'center': page.isSelected(1) , 'left': !page.isSelected(1)  }">

Or use the ternary operator:

<div id="homePage" ng-class="page.isSelected(1) ? 'center' : 'left'">

I used this code for that:

ColorMatrix matrix = new ColorMatrix();
matrix.setSaturation(0);
ColorMatrixColorFilter filter = new ColorMatrixColorFilter(matrix);
profilePicture.setColorFilter(filter);

I was trying to achieve this but in the context of a MAVEN build. As part of my pom.xml configuration, I had a reference to an environment variable as part of a path to a local JAR:

<dependency>
  <groupId>the group id</groupId>
  <artifactId>the artifact id</artifactId>
  <version>the version</version>
  <scope>system</scope>
    <systemPath>${env.MY_ENV_VARIABLE}/the_local_jar_archive.jar</systemPath>
</dependency>

To compile my project, I had to define the environment variable as part of the run configuration for the maven build as explained by Max's answer. I was able to launch the maven compilation and the project would compile just fine.

However, as this environment variable involves some dependencies, the default "problems" view of Eclipse (where compilation errors/warnings usually show) would still show errors along the lines of Could not find artifact and systemPath should be an absolute path but is ${env.MY_ENV_VARIABLE}/the_local_jar_archive.jar.

How I fixed it

Go into Window -> Preferences -> General -> Worksapce -> Linked Resources and define a new path variable.

Finally, in my case I just needed to Right click on my pom.xml file, select Maven -> Update Project and the errors disappeared from the "Problems" view.

I understand your problem boils down to how to call a SOAP (JAX-WS) web service from Java and get its returning object. In that case, you have two possible approaches:

1. Generate the Java classes through wsimport and use them; or
2. Create a SOAP client that:
   1. Serializes the service's parameters to XML;
   2. Calls the web method through HTTP manipulation; and
   3. Parse the returning XML response back into an object.

About the first approach (using wsimport):

I see you already have the services' (entities or other) business classes, and it's a fact that the wsimport generates a whole new set of classes (that are somehow duplicates of the classes you already have).

I'm afraid, though, in this scenario, you can only either:

• Adapt (edit) the wsimport generated code to make it use your business classes (this is difficult and somehow not worth it - bear in mind everytime the WSDL changes, you'll have to regenerate and readapt the code); or
• Give up and use the wsimport generated classes. (In this solution, you business code could "use" the generated classes as a service from another architectural layer.)

About the second approach (create your custom SOAP client):

In order to implement the second approach, you'll have to:

1. Make the call:
   • Use the SAAJ (SOAP with Attachments API for Java) framework (see below, it's shipped with Java SE 1.6 or above) to make the calls; or
   • You can also do it through java.net.HttpUrlconnection (and some java.io handling).
2. Turn the objects into and back from XML:
   • Use an OXM (Object to XML Mapping) framework such as JAXB to serialize/deserialize the XML from/into objects
   • Or, if you must, manually create/parse the XML (this can be the best solution if the received object is only a little bit differente from the sent one).

Creating a SOAP client using classic java.net.HttpUrlConnection is not that hard (but not that simple either), and you can find in this link a very good starting code.

I recommend you use the SAAJ framework:

SOAP with Attachments API for Java (SAAJ) is mainly used for dealing directly with SOAP Request/Response messages which happens behind the scenes in any Web Service API. It allows the developers to directly send and receive soap messages instead of using JAX-WS.

See below a working example (run it!) of a SOAP web service call using SAAJ. It calls this web service.

import javax.xml.soap.*;

public class SOAPClientSAAJ {

About using JAXB for serializing/deserializing, it is very easy to find information about it. You can start here: http://www.mkyong.com/java/jaxb-hello-world-example/.

Another example of correct compression and decompression:

@Slf4j
public class GZIPCompression {
    public static byte[] compress(final String stringToCompress) {
        if (isNull(stringToCompress) || stringToCompress.length() == 0) {
            return null;
        }

        try (final ByteArrayOutputStream baos = new ByteArrayOutputStream();
            final GZIPOutputStream gzipOutput = new GZIPOutputStream(baos)) {
            gzipOutput.write(stringToCompress.getBytes(UTF_8));
            gzipOutput.finish();
            return baos.toByteArray();
        } catch (IOException e) {
            throw new UncheckedIOException("Error while compression!", e);
        }
    }

    public static String decompress(final byte[] compressed) {
        if (isNull(compressed) || compressed.length == 0) {
            return null;
        }

        try (final GZIPInputStream gzipInput = new GZIPInputStream(new ByteArrayInputStream(compressed));
             final StringWriter stringWriter = new StringWriter()) {
            IOUtils.copy(gzipInput, stringWriter, UTF_8);
            return stringWriter.toString();
        } catch (IOException e) {
            throw new UncheckedIOException("Error while decompression!", e);
        }
    }
}

Please note that IDEs like IntelliJ IDEA tend to start their own adb-server.

Even manually killing the server and running an new instance with sudo won't help here until you make your IDE kill the server itself.

It took me more than 4 hours to fix this problem. I followed the guide from http://docs.phonegap.com/en/2.1.0/guide_getting-started_android_index.md.html#Getting%20Started%20with%20Android

I'm using Android Studio (Eclipse with ADT could not work properly because of the build problem).

Solution that worked for me:

1. I put the /assets/www/index.html under app/src/main/assets directory. (take care AndroidStudio has different perspectives like Project or Android)

2. use super.loadUrl("file:///android_asset/www/index.html"); instead of super.loadUrl("file:///android_assets/www/index.html"); (no s)

i had to change my form's POST to a GET. i was just doing a demo post to an html page, on a test azure site. read this for info: http://support.microsoft.com/kb/942051

For those who use Data Binding:

1. Add the following static method to any class

   @BindingAdapter("app:thumbTintCompat")
   public static void setThumbTint(SeekBar seekBar, @ColorInt int color) {
       seekBar.getThumb().setColorFilter(color, PorterDuff.Mode.SRC_IN);
   }
   

2. Add app:thumbTintCompat attribute to your SeekBar

   <SeekBar
          android:id="@+id/seek_bar"
          style="@style/Widget.AppCompat.SeekBar"
          android:layout_width="wrap_content"
          android:layout_height="wrap_content"
          app:thumbTintCompat="@{@android:color/white}"
   />
   

That's it. Now you can use app:thumbTintCompat with any SeekBar. The progress tint can be configured in the same way.

Note: this method is also compatble with pre-lollipop devices.

I had this issue, I was scratching my head for the best part of two days.

Turns out I completely forgot I had CloudFlare setup on the domain I was live testing on.

CloudFlare caches your JavaScript and CSS. Turned on development mode and BAM!

Seriously... two whole days.

It's not the angular way, remove the function from html body and use it in controller, or use

angular.element(document).ready

Most of these answers are old. The latest Safari 14.0.2 (in 2021), has the option to Disable Cross-Origin Restrictions, however, it doesn't work if the paths have ../../ kind of path names; even though Safari correctly resolves to a local file path, it still doesn't permit loading the file, even though it exists. This is a recent bug in Safari 14 that didn't happen in 13.

Not relevant to your example, but you can also get the Bad substitution error in Bash for any substitution syntax that Bash does not recognize. This could be:

• Stray whitespace. E.g. bash -c '${x }'
• A typo. E.g. bash -c '${x;-}'
• A feature that was added in a later Bash version. E.g. bash -c '${x@Q}' before Bash 4.4.

If you have multiple substitutions in the same expression, Bash may not be very helpful in pinpointing the problematic expression. E.g.:

$ bash -c '"${x } multiline string
$y"'
bash: line 1: ${x } multiline string
$y: bad substitution

I recommend checking for invalid dates too:

set @PreviousStartDate=case ISDATE(@PreviousStartDate) 
    when 1 then @PreviousStartDate 
        else '1/1/2010'
    end

I understand that this is an old post but Windows is definitely not written in C++. There is lots of C++ in it but what we technical define as an operating system is not in C++. The Windows API, the Windows kernel (both of these are in essence what an operating system is) are written in C. Years ago I was given some leaked code for both Windows 2000 and Windows XP. The code was not nearly complete enough to compile the kernel or API but we were able to compile individual programs and services. For example, we were able to successfully compile Notepad.exe, mspaint.exe, and the spoolsv.exe service (print spooler). All written in C. I have not looked again but I am sure that leaked code still survives as torrent files out there that may still be available.

You should grab the standard input of the su process just launched and write down the command there, otherwise you are running the commands with the current UID.

Try something like this:

try{
    Process su = Runtime.getRuntime().exec("su");
    DataOutputStream outputStream = new DataOutputStream(su.getOutputStream());

    outputStream.writeBytes("screenrecord --time-limit 10 /sdcard/MyVideo.mp4\n");
    outputStream.flush();

    outputStream.writeBytes("exit\n");
    outputStream.flush();
    su.waitFor();
}catch(IOException e){
    throw new Exception(e);
}catch(InterruptedException e){
    throw new Exception(e);
}

Using JDBC in Java:

    String quer="SELECT * FROM sample2 where 1=2";
    
    Statement st=con.createStatement();
    ResultSet rs=st.executeQuery(quer);
    ResultSetMetaData rsmd = rs.getMetaData();
    int NumOfCol=0;
    NumOfCol=rsmd.getColumnCount();
    System.out.println("Query Executed!! No of Colm="+NumOfCol);

Your second String.Format uses {2} as a placeholder but you're only passing in one argument, so you should use {0} instead.

Change this:

String.Format("{2}", reader.GetString(0));

To this:

String.Format("{0}", reader.GetString(2));

You can do it like that

Expanded(
   child: Text(
   'Text',
   overflow: TextOverflow.ellipsis,
   maxLines: 1
   )
)

The Philippe solution but cleaner:

My subtraction data is: '2018-09-22T11:05:00.000Z'

import datetime
import pandas as pd

df_modified = pd.to_datetime(df_reference.index.values) - datetime.datetime(2018, 9, 22, 11, 5, 0)

This worked for me.

pip3 install --user package-name  # for Python3
pip install --user package-name   # for Python2

The --user flag tells Python to install in the user home directory. By default it will go to system locations. credit

I do not believe this is possible. You could add class1 to all elements which also have class2. If this is not practical to do manually, you could do it automatically with JavaScript (fairly easy to do with jQuery).

Check the mozilla documentation on window.open. The window features ("directory=...,...,height=350") etc. arguments should be a string:

window.open('/pageaddress.html','winname',"directories=0,titlebar=0,toolbar=0,location=0,status=0,menubar=0,scrollbars=no,resizable=no,width=400,height=350");

Try if that works in your browsers. Note that some of the features might be overridden by user preferences, such as "location" (see doc.)

Try this,

1. If you want to skip a particular iteration, use continue.

2. If you want to break out of the immediate loop use break

3 If there are 2 loop, outer and inner.... and you want to break out of both the loop from the inner loop, use break with label.

eg:

continue

for(int i=0 ; i<5 ; i++){

    if (i==2){

      continue;
    }
 }

eg:

break

for(int i=0 ; i<5 ; i++){

        if (i==2){

          break;
        }
     }

eg:

break with label

lab1: for(int j=0 ; j<5 ; j++){
     for(int i=0 ; i<5 ; i++){

        if (i==2){

          break lab1;
        }
     }
  }

I wouldn't go with MSTest. Although it's probably the most future proof of the frameworks with Microsoft behind it's not the most flexible solution. It won't run stand alone without some hacks. So running it on a build server other than TFS without installing Visual Studio is hard. The visual studio test-runner is actually slower than Testdriven.Net + any of the other frameworks. And because the releases of this framework are tied to releases of Visual Studio there are less updates and if you have to work with an older VS you're tied to an older MSTest.

I don't think it matters a lot which of the other frameworks you use. It's really easy to switch from one to another.

I personally use XUnit.Net or NUnit depending on the preference of my coworkers. NUnit is the most standard. XUnit.Net is the leanest framework.

Use the following code in your controller:

return Json(new { success = string }, JsonRequestBehavior.AllowGet);

and in JavaScript:

success: function (data) {
    var response = data.success;
    ....
}

Try this:

private void txtEntry_KeyUp(object sender, KeyEventArgs e)
    {
        if (e.KeyCode == Keys.Enter)
        {
            string trimText;

            trimText = this.txtEntry.Text.Replace("\r\n", "").ToString();
            this.txtEntry.Text = trimText;
            btnEnter.PerformClick();
        }
    }

for first 10 rows...

SELECT * FROM msgtable WHERE cdate='18/07/2012' LIMIT 0,10

for next 10 rows

SELECT * FROM msgtable WHERE cdate='18/07/2012' LIMIT 10,10

CDATA stands for Character Data. You can use this to escape some characters which otherwise will be treated as regular XML. The data inside this will not be parsed. For example, if you want to pass a URL that contains & in it, you can use CDATA to do it. Otherwise, you will get an error as it will be parsed as regular XML.
