There are multiple problems here
Ex
$(document).ready(function(){
$("#addCF").click(function(){
$("#customFields").append('<tr valign="top"><th scope="row"><label for="customFieldName">Custom Field</label></th><td><input type="text" class="code" id="customFieldName" name="customFieldName[]" value="" placeholder="Input Name" /> <input type="text" class="code" id="customFieldValue" name="customFieldValue[]" value="" placeholder="Input Value" /> <a href="javascript:void(0);" id="remCF">Remove</a></td></tr>');
});
$("#customFields").on('click', '#remCF', function(){
$(this).parent().parent().remove();
});
});
Demo: Fiddle
See this demo where id properties are removed.
$(document).ready(function(){
$("#addCF").click(function(){
$("#customFields").append('<tr valign="top"><th scope="row"><label for="customFieldName">Custom Field</label></th><td><input type="text" class="code" name="customFieldName[]" value="" placeholder="Input Name" /> <input type="text" class="code" name="customFieldValue[]" value="" placeholder="Input Value" /> <a href="javascript:void(0);" class="remCF">Remove</a></td></tr>');
});
$("#customFields").on('click', '.remCF', function(){
$(this).parent().parent().remove();
});
});
You could try:
$(this).closest(".column").prev().find(".inputQty").val();
the approach you took is good. Just Implementation may need to be better. For instance ReturningValues should be well defined and Its better if you can make ReturningValues as immutable.
// this approach is better
public static ReturningValues myMethod() {
ReturningValues rv = new ReturningValues("value", 12);
return rv;
}
public final class ReturningValues {
private final String value;
private final int index;
public ReturningValues(String value, int index) {
this.value = value;
this.index = index;
}
}
Or if you have lots of key value pairs you can use HashMap then
public static Map<String,Object> myMethod() {
Map<String,Object> map = new HashMap<String,Object>();
map.put(VALUE, "value");
map.put(INDEX, 12);
return Collections.unmodifiableMap(map); // try to use this
}
You can do Your own Animation style as an xml file like this(put it in anim folder):
left to right:
<set xmlns:android="http://schemas.android.com/apk/res/android"
android:shareInterpolator="false">
<translate android:fromXDelta="-100%" android:toXDelta="0%"
android:fromYDelta="0%" android:toYDelta="0%"
android:duration="500"/>
</set>
right to left:
<set xmlns:android="http://schemas.android.com/apk/res/android"
android:shareInterpolator="false">
<translate
android:fromXDelta="0%" android:toXDelta="100%"
android:fromYDelta="0%" android:toYDelta="0%"
android:duration="500" />
</set>
here You can set Your own values at duration, maybe it depends on the phone model how the animation will look like, try some values out if it looks not good.
and then You can call it in Your activity:
Intent animActivity = new Intent(this,YourStartAfterAnimActivity.class);
startActivity(nextActivity);
overridePendingTransition(R.anim.your_left_to_right, R.anim.your_right_to_left);
You can use the Partial
mapped type as explained in the documentation:
https://www.typescriptlang.org/docs/handbook/release-notes/typescript-2-1.html
In your example, you'll have:
interface IX {
a: string;
b: any;
c: AnotherType;
}
let x: Partial<IX> = {
a: 'abc'
}
Remember that with the binding redirection
oldVersion="0.0.0.0-6.0.0.0"
You are saying that the old versions of the dll are between version 0.0.0.0 and version 6.0.0.0.
If you want the branch too:
gem 'foo', path: "point/to/your/path", branch: "branch-name"
truncate did not work for me, delete + reseed is the best way out. In case there are some of you out there who need to iterate over huge number of tables to perform delete + reseed, you might run into issues with some tables which does not have an identity column, the following code checks if identity column exist before attempting to reseed
EXEC ('DELETE FROM [schemaName].[tableName]')
IF EXISTS (Select * from sys.identity_columns where object_name(object_id) = 'tableName')
BEGIN
EXEC ('DBCC CHECKIDENT ([schemaName.tableName], RESEED, 0)')
END

Yes, the constant CI_VERSION
will give you the current CodeIgniter version number. It's defined in: /system/codeigniter/CodeIgniter.php As of CodeIgniter 2, it's defined in /system/core/CodeIgniter.php
For example,
echo CI_VERSION; // echoes something like 1.7.1
function tar.create() {
local folder="${1}"
local tar="$(basename "${folder}")".tar.gz
cd "${folder}" && tar -zcvf "../${tar}" .; cd - &> /dev/null
}
Example:
tar.create /path/to/folder
You are welcome.
I had similar issue and the below line helped me solving the issue.Thanks to rene. I just pasted this line above the authentication code and it worked
ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;
Improvement to kaiser's answer:
var myEl = $document.find('#some-id');
Don't forget to inject $document
into your directive
Took me a while to get this working based on some of the answers above, so I thought I'd share it for others to use. I hope it's useful.
'use strict';
const functions = require('firebase-functions');
const admin = require('firebase-admin');
admin.initializeApp();
const db = admin.firestore();
exports.countDocumentsChange = functions.firestore.document('library/{categoryId}/documents/{documentId}').onWrite((change, context) => {
const categoryId = context.params.categoryId;
const categoryRef = db.collection('library').doc(categoryId)
let FieldValue = require('firebase-admin').firestore.FieldValue;
if (!change.before.exists) {
// new document created : add one to count
categoryRef.update({numberOfDocs: FieldValue.increment(1)});
console.log("%s numberOfDocs incremented by 1", categoryId);
} else if (change.before.exists && change.after.exists) {
// updating existing document : Do nothing
} else if (!change.after.exists) {
// deleting document : subtract one from count
categoryRef.update({numberOfDocs: FieldValue.increment(-1)});
console.log("%s numberOfDocs decremented by 1", categoryId);
}
return 0;
});
Use a memory stream
using(MemoryStream ms = new MemoryStream())
{
image.Save(ms, ...);
return ms.ToArray();
}
Here is my original solution:
var app = angular.module('plunker', []);
app.directive('autoFocus', function($timeout) {
return {
link: function (scope, element, attrs) {
attrs.$observe("autoFocus", function(newValue){
if (newValue === "true")
$timeout(function(){element[0].focus()});
});
}
};
});
And the HTML:
<button ng-click="isVisible = !isVisible">Toggle input</button>
<input ng-show="isVisible" auto-focus="{{ isVisible }}" value="auto-focus on" />
It focuses the input as it becomes visible with ng-show. No use of $watch or $on here.
When you use setcookie
, you can either set the expiration time to 0
or simply omit the parametre - the cookie will then expire at the end of session (ie, when you close the browser).
I have been using restler for making webservices call, works like charm and is pretty neat.
Try this as root (maybe you can use sudo
or su
):
/etc/init.d/postgresql restart
Without any argument the script also gives you a hint on how to restart a specific version
[Uqbar@Feynman ~] /etc/init.d/postgresql
Usage: /etc/init.d/postgresql {start|stop|restart|reload|force-reload|status} [version ...]
Similarly, in case you have it, you can also use the service
tool:
[Uqbar@Feynman ~] service postgresql
Usage: /etc/init.d/postgresql {start|stop|restart|reload|force reload|status} [version ...]
Please, pay attention to the optional [version ...]
trailing argument.
That's meant to allow you, the user, to act on a specific version, in case you were running multiple ones. So you can restart version X while keeping version Y and Z untouched and running.
Finally, in case you are running systemd, then you can use systemctl
like this:
[support@Feynman ~] systemctl status postgresql
? postgresql.service - PostgreSQL database server
Loaded: loaded (/usr/lib/systemd/system/postgresql.service; enabled; vendor preset: disabled)
Active: active (running) since Wed 2017-11-14 12:33:35 CET; 7min ago
...
You can replace status
with stop
, start
or restart
as well as other actions. Please refer to the documentation for full details.
In order to operate on multiple concurrent versions, the syntax is slightly different. For example to stop v12
and reload v13
you can run:
systemctl stop postgresql-12.service
systemctl reload postgresql-13.service
Thanks to @Jojo for pointing me to this very one.
Finally Keep in mind that root
permissions may be needed for non-informative tasks as in the other cases seen earlier.
Either $objPage
is not an instance variable OR your are overwriting $objPage
with something that is not an instance of class PageAttributes
.
You may be able to use the aggregate
(or agg
) function to concatenate the values. (Untested code)
df.groupby('A')['B'].agg(lambda col: ''.join(col))
Default-Values are only considered for parameters NOT given to the function.
So given a function
procedure foo( bar1 IN number DEFAULT 3,
bar2 IN number DEFAULT 5,
bar3 IN number DEFAULT 8 );
if you call this procedure with no arguments then it will behave as if called with
foo( bar1 => 3,
bar2 => 5,
bar3 => 8 );
but 'NULL' is still a parameter.
foo( 4,
bar3 => NULL );
This will then act like
foo( bar1 => 4,
bar2 => 5,
bar3 => Null );
( oracle allows you to either give the parameter in order they are specified in the procedure, specified by name, or first in order and then by name )
one way to treat NULL the same as a default value would be to default the value to NULL
procedure foo( bar1 IN number DEFAULT NULL,
bar2 IN number DEFAULT NULL,
bar3 IN number DEFAULT NULL );
and using a variable with the desired value then
procedure foo( bar1 IN number DEFAULT NULL,
bar2 IN number DEFAULT NULL,
bar3 IN number DEFAULT NULL )
AS
v_bar1 number := NVL( bar1, 3);
v_bar2 number := NVL( bar2, 5);
v_bar3 number := NVL( bar3, 8);
cursor.execute(sql,array)
Only takes two arguments.
It will iterate the "array"-object and match ? in the sql-string.
(with sanity checks to avoid sql-injection)
I am wondering if you are after something like Squiggle. Also something very useful is jDBI. It won't help you with the queries though.

It's the year 2015. The correct answer to this question at this point is to use CSS white-space: pre-line
or white-space: pre-wrap
. Clean and elegant. The lowest version of IE that supports the pair is 8.
https://css-tricks.com/almanac/properties/w/whitespace/
P.S. Until CSS3 become common you'd probably need to manually trim off initial and/or trailing white-spaces.
I ended up here thinking that my tests weren't run in order, but the truth is that the mess was in my async jobs. When working with concurrency you need to perform concurrency checks between your tests as well. In my case, jobs and tests share a semaphore, so next tests hang until the running job releases the lock.
I know this is not fully related to this question, but maybe could help targeting the correct issue
This question is the first result for Googling "svg rounded corners path". Phrogz suggestion to use stroke
has some limitations (namely, that I cannot use stroke for other purposes, and that the dimensions have to be corrected for the stroke width).
Jlange suggestion to use a curve is better, but not very concrete. I ended up using quadratic Bézier curves for drawing rounded corners. Consider this picture of a corner marked with a blue dot and two red points on adjacent edges:
The two lines could be made with the L
command. To turn this sharp corner into a rounded corner, start drawing a curve from the left red point (use M x,y
to move to that point). Now a quadratic Bézier curve has just a single control point which you must set on the blue point. Set the end of the curve at the right red point. As the tangent at the two red points are in the direction of the previous lines, you will see a fluent transition, "rounded corners".
Now to continue the shape after the rounded corner, a straight line in a Bézier curve can be achieved by setting the control point between on the line between the two corners.
To help me with determining the path, I wrote this Python script that accepts edges and a radius. Vector math makes this actually very easy. The resulting image from the output:
#!/usr/bin/env python
# Given some vectors and a border-radius, output a SVG path with rounded
# corners.

Alternatively, since pip

python2.7 -m pip install foo
You can use "
Open gradle.properties

android.useAndroidX=false
android.enableJetifier=false
or U can use these dependencies too:
implementation 'androidx.appcompat:appcompat:1.0.2'
implementation 'androidx.annotation:annotation:1.0.2'
What I'd try first is
to drop all constraints, indexes, triggers and full text indexes first before you update.
If above wasn't performant enough, my next move would be
to create a CSV file with 12 million records and bulk import it using bcp.
Lastly, I'd create a new heap table (meaning table with no primary key) with no indexes on a different filegroup, populate it with -1. Partition the old table, and add the new partition using "switch".
base on @Michael answer, add check whether listFiles return null
static Stream<File> files(File file) {
return file.isDirectory()
? Optional.ofNullable(file.listFiles()).map(Stream::of).orElseGet(Stream::empty).flatMap(MainActivity::files)

or use Lightweight-Stream-API, which support Android5 & Android6

I searched for solution to prevent resubmission in a huge project afterwards. The code highly works with $_GET and $_POST and I can't change the form elements behaviour without the risk of unforeseen bugs. So, here is my code:
<!-- language: lang-php -->
<?php
// Very top of your code:
// Start session:
session_start();
// If Post Form Data send and no File Upload
if ( empty( $_FILES ) && ! empty( $_POST ) ) {
// Store Post Form Data in Session Variable
$_SESSION["POST"] = $_POST;
// Reload Page if there were no outputs
if ( ! headers_sent() ) {
// Build URL to reload with GET Parameters
// Change https to http if your site has no ssl
$location = "https://" . $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI'];
// Reload Page
header( "location: " . $location, true, 303 );
// Stop any further progress
die();
}
}
// Rebuilt POST Form Data from Session Variable
if ( isset( $_SESSION["POST"] ) ) {
$_POST = $_SESSION["POST"];
// Tell PHP that POST is sent
$_SERVER['REQUEST_METHOD'] = 'POST';
}
// Your code:

// Very Bottom of your code:
// Kill Post Form Data Session Variable, so User can reload the Page without sending post data twice
unset( $_SESSION["POST"] );
It only works to avoid the resubmit of $_POST, not $_GET. But this is the behaviour I need. The resubmit issue doesn't work with file uploads!
I use matplotlib for reading TIFF files:
import matplotlib.pyplot as plt
I = plt.imread(tiff_file)
and I
will be of type ndarray
.
According to the documentation though it is actually PIL that works behind the scenes when handling TIFFs as matplotlib only reads PNGs natively, but this has been working fine for me.
There's also a plt.imsave
function for saving.
You can use constructor property:
'foo'.constructor == String // returns true
true.constructor == Boolean // returns true
Default methods in Java interface enables interface evolution.
Given an existing interface, if you wish to add a method to it without breaking the binary compatibility with older versions of the interface, you have two options at hands: add a default or a static method. Indeed, any abstract method added to the interface would have to be impleted by the classes or interfaces implementing this interface.
A static method is unique to a class. A default method is unique to an instance of the class.
If you add a default method to an existing interface, classes and interfaces which implement this interface do not need to implement it. They can
More on the topic here.
You should hook onto the change event of the <select>
element instead of on the individual options.
var select = document.getElementById('test'),
onChange = function(event) {
var shown = this.options[this.selectedIndex].value == 1;
document.getElementById('hidden_div').style.display = shown ? 'block' : 'none';
};
// attach event handler
if (window.addEventListener) {
select.addEventListener('change', onChange, false);
} else {
// of course, IE < 9 needs special treatment
select.attachEvent('onchange', function() {
onChange.apply(select, arguments);
});
}
Have a look at these methods:
byte [] StructureToByteArray(object obj)
{
int len = Marshal.SizeOf(obj);
byte [] arr = new byte[len];
IntPtr ptr = Marshal.AllocHGlobal(len);
Marshal.StructureToPtr(obj, ptr, true);
Marshal.Copy(ptr, arr, 0, len);
Marshal.FreeHGlobal(ptr);
return arr;
}
void ByteArrayToStructure(byte [] bytearray, ref object obj)
{
int len = Marshal.SizeOf(obj);
IntPtr i = Marshal.AllocHGlobal(len);
Marshal.Copy(bytearray,0, i,len);
obj = Marshal.PtrToStructure(i, obj.GetType());
Marshal.FreeHGlobal(i);
}
This is a shameless copy of another thread which I found upon Googling!

Those are unicode escapes. The general unicode escapes looks like \uxxxx
where xxxx
are the hexadecimal digits of the ASCI characters. They are used mainly to insert special characters inside a javascript string.
Call
perror("execl");
in case of error.
Sample:
if(read(fd, buf, 1)==-1) {
perror("read");
}
The manpages of errno(3)
and perror(3)
are interesting, too...
The reason why the sublime documented shortcuts for Mac does not work are they are linked to the shortcuts of other Mac functionalities such as Mission Control, Application Windows, etc. Solution: Go to System Preferences -> Keyboard -> Shortcuts and then un-check the options for Mission Control and Application Windows. Now try "Control + Shift [+ Arrow keys]" for selecting the required text and then move the cursor to the required location without any mouse click, so that the selection can be pasted with the correct indentation at the required location.
I think that parse_str is what you're looking for, something like this should do the trick for you:
parse_str($_SERVER['QUERY_STRING'], $vars);
Then the $vars
array will hold all the passed arguments.
You could also use a session for passing small bits of info. You will need to have session_start(); at the top of the PHP pages that use the session else the variables will not be accessable
page1.php
<?php
session_start();
$_SESSION['superhero'] = "batman";
?>
<a href="page2.php" title="">Go to the other page</a>
page2.php
<?php
session_start(); // this NEEDS TO BE AT THE TOP of the page before any output etc

I work with telerik radcontrols that's why I Find a control, but you can find control directly like: $('#IdExample').css({
this code works for me, I hope help you and sorry my english.
Code Javascript:
<script type="javascript">
function changeToUpperCase(event, obj) {
var txtDescripcion = $("#%=RadPanelBar1.Items(0).Items(0).FindControl("txtDescripcion").ClientID%>");
txtDescripcion.css({
"text-transform": "uppercase"
});
} </script>
Code ASP.NET
<asp:TextBox ID="txtDescripcion" runat="server" MaxLength="80" Width="500px" onkeypress="return changeToUpperCase(event,this)"></asp:TextBox>
This worked for me :
document.getElementById('yourDivID').scrollIntoView();
Using jQuery:
$(document).ready(function(){
$('div').click(function(){
$(this).toggleClass('clicked');
});
});?
No, it is not a bug. It is a result of how the ParameterizedTypeReference
hack works.
If you look at its implementation, it uses Class#getGenericSuperclass()
which states
Returns the Type representing the direct superclass of the entity (class, interface, primitive type or void) represented by this Class.
If the superclass is a parameterized type, the
Type
object returned must accurately reflect the actual type parameters used in the source code.
So, if you use
new ParameterizedTypeReference<ResponseWrapper<MyClass>>() {}
it will accurately return a Type
for ResponseWrapper<MyClass>
.
If you use
new ParameterizedTypeReference<ResponseWrapper<T>>() {}
it will accurately return a Type
for ResponseWrapper<T>
because that is how it appears in the source code.
When Spring sees T
, which is actually a TypeVariable
object, it doesn't know the type to use, so it uses its default.
You cannot use ParameterizedTypeReference
the way you are proposing, making it generic in the sense of accepting any type. Consider writing a Map
with key Class
mapped to a predefined ParameterizedTypeReference
for that class.
You can subclass ParameterizedTypeReference
and override its getType
method to return an appropriately created ParameterizedType
, as suggested by IonSpin.

Use the INTERVAL
type to it. E.g:
--yesterday
SELECT NOW() - INTERVAL '1 DAY';
--Unrelated to the question, but PostgreSQL also supports some shortcuts:
SELECT 'yesterday'::TIMESTAMP, 'tomorrow'::TIMESTAMP, 'allballs'::TIME;
Then you can do the following on your query:
SELECT
org_id,
count(accounts) AS COUNT,
((date_at) - INTERVAL '1 DAY') AS dateat
FROM
sourcetable
WHERE
date_at <= now() - INTERVAL '130 DAYS'
GROUP BY
org_id,
dateat;
You can append multiple operands. E.g.: how to get last day of current month?
SELECT date_trunc('MONTH', CURRENT_DATE) + INTERVAL '1 MONTH - 1 DAY';
You can also create an interval using make_interval
function, useful when you need to create it at runtime (not using literals):
SELECT make_interval(days => 10 + 2);
SELECT make_interval(days => 1, hours => 2);
SELECT make_interval(0, 1, 0, 5, 0, 0, 0.0);
I was searching how to do something similar in WPF and I got this solution:
<ItemsControl ItemsSource="{Binding MyItems,Mode=OneWay}">
<ItemsControl.ItemsPanel>
<ItemsPanelTemplate>
<StackPanel Orientation="Vertical" />
</ItemsPanelTemplate>
</ItemsControl.ItemsPanel>
<ItemsControl.ItemTemplate>
<DataTemplate>
<RadioButton
Content="{Binding}"
Command="{Binding Path=DataContext.CustomCommand,
RelativeSource={RelativeSource Mode=FindAncestor,
AncestorType={x:Type ItemsControl}} }"
CommandParameter="{Binding}" />
</DataTemplate>
</ItemsControl.ItemTemplate>
I hope this works for somebody else. I have a data context which is set automatically to the ItemsControls, and this data context has two properties: MyItems
-which is a collection-, and one command 'CustomCommand'. Because of the ItemTemplate
is using a DataTemplate
, the DataContext
of upper levels is not directly accessible. Then the workaround to get the DC of the parent is use a relative path and filter by ItemsControl
type.
There are few steps to overcome this problem:
The problem solved: The problem raised to me at the uninstallation on openfire server.
That image is called 'favicon' and it's a small square shaped .ico
file, which is the standard file type for favicons. You could use .png
or .gif
too, but you should follow the standard for better compatibility.
To set one for your website you should:
Make a square image of your logo (preferably 32x32 or 16x16 pixels, as far as I know there's no max size*), and transform it into an .ico
file. You can do this on Gimp, Photoshop (with help of a plugin) or a website like Favicon.cc or RealFaviconGenerator.
Then, you have two ways of setting it up:
A) Placing it on the root folder/directory of your website (next to index.html
)
with the name favicon.ico
.
or
B) Link to it between the <head></head>
tags of every .html
file on your site, like this:
<head>
<link rel="shortcut icon" type="image/x-icon" href="favicon.ico" />
</head>
If you want to see the favicon
from any website, just write www.url.com/favicon.ico
and you'll (probably) see it. Stackoverflow's favicon is 16x16 pixels and Wikipedia is 32x32.
*: There's even a browser problem with no filesize limit. You could easily crash a browser with an exceedingly large favicon, more info here
Can you change the if condition to this:
if (!is.na(comments[l])) print(comments[l]);
You can only check for NA values with is.na().
Mustache templates are, by design, very simple; the homepage even says:
Logic-less templates.
So the general approach is to do your logic in JavaScript and set a bunch of flags:
if(notified_type == "Friendship")
data.type_friendship = true;
else if(notified_type == "Other" && action == "invite")
data.type_other_invite = true;
//...
and then in your template:
{{#type_friendship}}
friendship...
{{/type_friendship}}
{{#type_other_invite}}
invite...
{{/type_other_invite}}
If you want some more advanced functionality but want to maintain most of Mustache's simplicity, you could look at Handlebars:
Handlebars provides the power necessary to let you build semantic templates effectively with no frustration.
Mustache templates are compatible with Handlebars, so you can take a Mustache template, import it into Handlebars, and start taking advantage of the extra Handlebars features.
You can override some css
body {
padding-left: 0px !important;
padding-right: 0px !important;
}
.navbar-inner {
border-radius: 0px !important;
}
The !important
is needed just in case you link the bootstrap.css
after your custom css.
And add your nav html out of a .container
I have been trying to do this for a while also. Here is what I do now. Highlight the email you want to create as a file. Click on Create. Hover over Special, then click on Link message. This will open up a new tab for the link. At the bottom of the message is a small yellow piece of paper icon. Copy this icon and paste into your message like you would any other file. It is tiny, so I put a statement like "see email attachment ---->" in front of the icon. You might like this way. Not sure though.
You can do sizeof($Contents)
or count($Contents)
also this
$count = 0;
foreach($Contents as $items) {
$count++;
$items[number];
}
Assuming that it's a TCP (rather than UDP) port that you're trying to use:
On the server itself, use netstat -an
to check to see which ports are listening.
From outside, just use telnet host port
(or telnet host:port
on Unix systems) to see if the connection is refused, accepted, or timeouts.
On that latter test, then in general:
On Windows 7 or Windows Vista the default option 'telnet' is not recognized as an internal or external command, operable program or batch file. To solve this, just enable it: Click *Start** → Control Panel → Programs → Turn Windows Features on or off. In the list, scroll down and select Telnet Client and click OK.
This worked for me,
var loc = "abcdefghi".rangeOfString("c").location
NSLog("%d", loc);
this worked too,
var myRange: NSRange = "abcdefghi".rangeOfString("c")
var loc = myRange.location
NSLog("%d", loc);
This worked for me fine:
File 1:
<html>
<head></head>
<body>
<a href="#" onclick="window.open('file:///D:/Examples/file2.html'); return false">CLICK ME</a>
</body>
<footer></footer>
</html>
File 2:
<html>
...
</html>
This method works regardless of whether or not the 2 files are in the same directory, BUT both files must be local.
For obvious security reasons, if File 1 is located on a remote server you absolutely cannot open a file on some client's host computer and trying to do so will open a blank target.
Agree with Ali Parr. The WndTab Line Counter addin is a such tool. http://www.codeproject.com/KB/macros/linecount.aspx
It's also a good idea to search from download site to find some related tool. http://www.cnet.com/1770-5_1-0.html?query=code+counter&tag=srch
As I understand it, you want the server be able to send messages through from client 1 to client 2. You cannot directly connect two clients because one of the two ends of a WebSocket connection needs to be a server.
This is some pseudocodish JavaScript:
Client:
var websocket = new WebSocket("server address");
websocket.onmessage = function(str) {
console.log("Someone sent: ", str);
};
// Tell the server this is client 1 (swap for client 2 of course)
websocket.send(JSON.stringify({
id: "client1"
}));
// Tell the server we want to send something to the other client
websocket.send(JSON.stringify({
to: "client2",
data: "foo"
}));
Server:
var clients = {};
server.on("data", function(client, str) {
var obj = JSON.parse(str);
if("id" in obj) {
// New client, add it to the id/client object
clients[obj.id] = client;
} else {
// Send data to the client requested
clients[obj.to].send(obj.data);
}
});
I know this might be an old question but I just found myself in a situation where I had to implement this feature in a Laravel 5.7 app. Below is what worked from me.
$articles = Articles::where("created_at",">", Carbon::now()->subMonths(3))->get();
You will also need to use Carbon
use Carbon\Carbon;
You have to define your TASK_CAT
column first and then set foreign key on it.
private static final String TASK_TABLE_CREATE = "create table "
+ TASK_TABLE + " ("
+ TASK_ID + " integer primary key autoincrement, "
+ TASK_TITLE + " text not null, "
+ TASK_NOTES + " text not null, "
+ TASK_DATE_TIME + " text not null,"
+ TASK_CAT + " integer,"
+ " FOREIGN KEY ("+TASK_CAT+") REFERENCES "+CAT_TABLE+"("+CAT_ID+"));";
More information you can find on sqlite foreign keys doc.
if (strstr(request, "favicon") != NULL) {
// contains
}
I am using entity framework with LINQ. Following code was helpful for me;
1- For multiple records
using (var dbContext = new Chat_ServerEntities())
{
var allRec= dbContext.myEntities;
dbContext.myEntities.RemoveRange(allRec);
dbContext.SaveChanges();
}
2- For Single record
using (var dbContext = new Chat_ServerEntities())
{
var singleRec = dbContext.ChatUserConnections.FirstOrDefault( x => x.ID ==1);// object your want to delete
dbContext.ChatUserConnections.Remove(singleRec);
dbContext.SaveChanges();
}
C#
does not have a seperate runtime library. It uses .NET
as a runtime library.
Something like this should work: /([^/]*)$
What language are you using? End-of-string regex signifiers can vary in different languages.
I don't know why but I was had to use local folder before source server directive . to make it work

Goto my blog : retrofit with kotlin
the link below explains everything step by step.
http://loopj.com/android-async-http/
Here are sample apps:
Create a class :
public class HttpUtils {
private static final String BASE_URL = "http://api.twitter.com/1/";
private static AsyncHttpClient client = new AsyncHttpClient();
public static void get(String url, RequestParams params, AsyncHttpResponseHandler responseHandler) {
client.get(getAbsoluteUrl(url), params, responseHandler);
}
public static void post(String url, RequestParams params, AsyncHttpResponseHandler responseHandler) {
client.post(getAbsoluteUrl(url), params, responseHandler);
}
public static void getByUrl(String url, RequestParams params, AsyncHttpResponseHandler responseHandler) {
client.get(url, params, responseHandler);
}
public static void postByUrl(String url, RequestParams params, AsyncHttpResponseHandler responseHandler) {
client.post(url, params, responseHandler);
}
private static String getAbsoluteUrl(String relativeUrl) {
return BASE_URL + relativeUrl;
}
}
Call Method :
RequestParams rp = new RequestParams();
rp.add("username", "aaa"); rp.add("password", "aaa@123");
HttpUtils.post(AppConstant.URL_FEED, rp, new JsonHttpResponseHandler() {
@Override
public void onSuccess(int statusCode, Header[] headers, JSONObject response) {
// If the response is JSONObject instead of expected JSONArray
Log.d("asd", "---------------- this is response : " + response);
try {
JSONObject serverResp = new JSONObject(response.toString());
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
@Override
public void onSuccess(int statusCode, Header[] headers, JSONArray timeline) {
// Pull out the first event on the public timeline
}
});
Please grant internet permission in your manifest file.
<uses-permission android:name="android.permission.INTERNET" />
you can add compile 'com.loopj.android:android-async-http:1.4.9'
for Header[]
and compile 'org.json:json:20160212'
for JSONObject
in build.gradle file if required.
A little bit late for the party, but it's an interessting question.
You can write your own inc.bat for incrementing a number.
It can increment numbers from 0 to 9998.
@echo off
if "%1"==":inc" goto :increment
call %0 :inc %counter0%
set counter0=%_cnt%
if %_overflow%==0 goto :exit
call %0 :inc %counter1%
set counter1=%_cnt%
if %_overflow%==0 goto :exit
call %0 :inc %counter2%
set counter2=%_cnt%
if %_overflow%==0 goto :exit
call %0 :inc %counter3%
set counter3=%_cnt%
goto :exit
:increment
set _overflow=0
set _cnt=%2
if "%_cnt%"=="" set _cnt=0
if %_cnt%==9 goto :overflow
if %_cnt%==8 set _cnt=9
if %_cnt%==7 set _cnt=8
if %_cnt%==6 set _cnt=7
if %_cnt%==5 set _cnt=6
if %_cnt%==4 set _cnt=5
if %_cnt%==3 set _cnt=4
if %_cnt%==2 set _cnt=3
if %_cnt%==1 set _cnt=2
if %_cnt%==0 set _cnt=1
goto :exit
:overflow
set _cnt=0
set _overflow=1
goto :exit
:exit
set count=%counter3%%counter2%%counter1%%counter0%
A sample for using it is here
@echo off
set counter0=0
set counter1=
set counter2=
set counter3=
:loop
call inc.bat
echo %count%
if not %count%==250 goto :loop
Basically yes, JSON is just a javascript literal representation of your value so what you said is correct.
You can find a pretty clear and good explanation of JSON notation on http://json.org/
In Angular2+ for anyone interested:
<input type="text" placeholder="My Date" [ngModel]="myDate | date: 'longDate'">
with type of filters in DatePipe Angular.
looking at jQuery they in there jQuery.isArray(...)
they do:
isArray = Array.isArray || function( obj ) {
return jQuery.type(obj) === "array";
}
this leads us to: jQuery.type
:
type = function( obj ) {
return obj == null ?
String( obj ) :
class2type[ toString.call(obj) ] || "object";
}
and again we have to look in: class2type
class2type = {};
// Populate the class2type map
jQuery.each("Boolean Number String Function Array Date RegExp Object".split(" "), function(i, name) {
class2type[ "[object " + name + "]" ] = name.toLowerCase();
});
and in native JS:
var a, t = "Boolean Number String Function Array Date RegExp Object".split(" ");
for( a in t ) {
class2type[ "[object " + t[a] + "]" ] = t[a].toLowerCase();
}
this ends up with:
var isArray = Array.isArray || function( obj ) {
return toString.call(obj) === "[object Array]";
}
I like to have an "update count" in my shared preferences. If it's not there (or default zero value) then this is my app's "first use".
private static final int UPDATE_COUNT = 1; // Increment this on major change
...
if (sp.getInt("updateCount", 0) == 0) {
// first use
} else if (sp.getInt("updateCount", 0) < UPDATE_COUNT) {
// Pop up dialog telling user about new features
}
...
sp.edit().putInt("updateCount", UPDATE_COUNT);
So now, whenever there's an update to the app that users should know about, I increment UPDATE_COUNT
I'm surprised that nobody mention the problem with multiple input in CMS's very nice snipped.
Basically, you would have to define delay variable individually for each input. Otherwise if sb put text to first input and quickly jump to other input and start typing, callback for the first one WON'T be called!
See the code below I came with based on other answers:
(function($) {
/**
* KeyUp with delay event setup
*
* @link http://stackoverflow.com/questions/1909441/jquery-keyup-delay#answer-12581187
* @param function callback
* @param int ms
*/
$.fn.delayKeyup = function(callback, ms){
$(this).keyup(function( event ){
var srcEl = event.currentTarget;
if( srcEl.delayTimer )
clearTimeout (srcEl.delayTimer );
srcEl.delayTimer = setTimeout(function(){ callback( $(srcEl) ); }, ms);
});
return $(this);
};
})(jQuery);
This solution keeps setTimeout reference within input's delayTimer variable. It also passes reference of element to callback as fazzyx suggested.
Tested in IE6, 8(comp - 7), 8 and Opera 12.11.

These methods will only work on normal users because they most probably don't know about the inspector or how to check source code.
But a web developer can easily download these files, there is no such way you can disable the inspector completely.
At the end i would like to add few words.
Technically, Now think about this you are sending a Image from your server to another computer over HTTP, and you are at the same time trying to prevent it, it doesn't make any sense.....
you should always assume that anything that enters the machine of the user can be retrieved back now or later, no matter how hard you try, to hide it with encryption or maybe like youtube, sending the thing in chunks, and collecting them in browser.
getting the image ultimately is hard for a common user but not for people with a lot of technical background, maybe they are intercepting the entire network on Operating System Level, how you gonna stop them there.
You can use iterators:
Mat matrix = ...;
std::vector<float> vec(matrix.begin<float>(), matrix.end<float>());
One line in PowerShell 5.1 with administrator rights, Python 3.6.5, and pip version 10.0.1:
pip list -o --format json | ConvertFrom-Json | foreach {pip install $_.name -U --no-warn-script-location}
It works smoothly if there are no broken packages or special wheels in the list...
void foo(ref int? n)
{
return null;
}
An ico can be a png.
More precisely, you can store one or more png inside this minimal container format, instead of the usual bitmap+alpha that everyone strongly associates with ico.
Support is old, appearing in Windows Vista (2007) and is well supported by browsers, though not necessarily by icon editing software.
Any valid png (whole including header) can be prepended by a 6 byte ico header and 16 byte image directory.
GIMP has native support. Simply export as ico and tick "Compressed (PNG)".

To simplify this actions from accepted answer, you can also create Category for UIView
(since this works for all subclasses of UIView, not only for textfields:
UIView+Additions.h:
#import <Foundation/Foundation.h>
@interface UIView (Additions)
- (void)setBorderForColor:(UIColor *)color
width:(float)width
radius:(float)radius;
@end
UIView+Additions.m:
#import "UIView+Additions.h"
@implementation UIView (Additions)
- (void)setBorderForColor:(UIColor *)color
width:(float)width
radius:(float)radius
{
self.layer.cornerRadius = radius;
self.layer.masksToBounds = YES;
self.layer.borderColor = [color CGColor];
self.layer.borderWidth = width;
}
@end
Usage:
#import "UIView+Additions.h"
//...
[textField setBorderForColor:[UIColor redColor]
width:1.0f
radius:8.0f];
If the question is how to convert an integer itself (not its string equivalent) into bytes, I think the robust answer is:
>>> i = 5
>>> i.to_bytes(2, 'big')
b'\x00\x05'
>>> int.from_bytes(i.to_bytes(2, 'big'), byteorder='big')
5
More information on these methods here:
Not sure if this is what you're after, but it will loop through the range that you gave it and if it finds an "A" it will remove it from the cell. I'm not sure what oldStr is used for...
Private Sub foo()
Dim myString As String
RowCount = WorksheetFunction.CountA(Range("A:A"))
For i = 2 To RowCount
myString = Trim(Cells(i, 1).Value)
If InStr(myString, "A") > 0 Then
Cells(i, 1).Value = Left(myString, InStr(myString, "A"))
End If
Next
End Sub
Got another interesting method:
$array = array('a', 'b', 'c', 'd');
unset($array[2]);
$array = array_merge($array);
Now the $array keys are reset.
So I did some speed comparisons to get the fastest way. List comprehensions are indeed very fast. The only way to get close is to avoid bytecode getting exectuded during construction of the list. My first attempt was the following method, which would appear to be faster in principle:
l = [[]]
for _ in range(n): l.extend(map(list,l))
(produces a list of length 2**n, of course) This construction is twice as slow as the list comprehension, according to timeit, for both short and long (a million) lists.
My second attempt was to use starmap to call the list constructor for me, There is one construction, which appears to run the list constructor at top speed, but still is slower, but only by a tiny amount:
from itertools import starmap
l = list(starmap(list,[()]*(1<<n)))
Interesting enough the execution time suggests that it is the final list call that is makes the starmap solution slow, since its execution time is almost exactly equal to the speed of:
l = list([] for _ in range(1<<n))
My third attempt came when I realized that list(()) also produces a list, so I tried the apperently simple:
l = list(map(list, [()]*(1<<n)))
but this was slower than the starmap call.
Conclusion: for the speed maniacs: Do use the list comprehension. Only call functions, if you have to. Use builtins.
This should get you for starting with two letters and ending with two numbers.
[A-Za-z]{2}(.*)[0-9]{2}
If you know it will always be just two and two you can
[A-Za-z]{2}[0-9]{2}
I found the answer to may previous post. Here it is.
CREATE TABLE #TempTable (id int)
INSERT INTO @TestTable (col1, col2) OUTPUT INSERTED.id INTO #TempTable select 1,2
INSERT INTO @TestTable (col1, col2) OUTPUT INSERTED.id INTO #TempTable select 3,4
SELECT * FROM #TempTable --this select will chage @@ROWCOUNT value
You'll have to use the "userInfo" variant and pass a NSDictionary object that contains the messageTotal integer:
NSDictionary* userInfo = @{@"total": @(messageTotal)};
NSNotificationCenter* nc = [NSNotificationCenter defaultCenter];
[nc postNotificationName:@"eRXReceived" object:self userInfo:userInfo];
On the receiving end you can access the userInfo dictionary as follows:
-(void) receiveTestNotification:(NSNotification*)notification
{
if ([notification.name isEqualToString:@"TestNotification"])
{
NSDictionary* userInfo = notification.userInfo;
NSNumber* total = (NSNumber*)userInfo[@"total"];
NSLog (@"Successfully received test notification! %i", total.intValue);
}
}
Why don't you rather use phplist? It's also built on top of PHP Mailer and a lot of industry leaders are using it. I've used it myself a couple of times to send out bulk mails to my clients. The nice thing about phplist is that you can throttle your messages on a domain level plus a time limit level.
What we've also done with a couple of internal capture systems we've got was to push our user base to the mailling list and then have a cron entry triggering a given mail each day. The possibilities are endless, that's the awesome thing about open source!
reserve when you do not want the objects to be initialized when reserved. also, you may prefer to logically differentiate and track its count versus its use count when you resize. so there is a behavioral difference in the interface - the vector will represent the same number of elements when reserved, and will be 100 elements larger when resized in your scenario.
Is there any better choice in this kind of scenario?
it depends entirely on your aims when fighting the default behavior. some people will favor customized allocators -- but we really need a better idea of what it is you are attempting to solve in your program to advise you well.
fwiw, many vector implementations will simply double the allocated element count when they must grow - are you trying to minimize peak allocation sizes or are you trying to reserve enough space for some lock free program or something else?
This works: (thanks to the comments)
setTimeout(() =>

You can also use joblib.dump and joblib.load which is much more efficient at handling numerical arrays than the default python pickler.
Joblib is included in scikit-learn:
>>> import joblib
>>> from sklearn.datasets import load_digits
>>> from sklearn.linear_model import SGDClassifier
>>> digits = load_digits()
>>> clf = SGDClassifier().fit(digits.data, digits.target)
>>> clf.score(digits.data, digits.target) # evaluate training error
0.9526989426822482
>>> filename = '/tmp/digits_classifier.joblib.pkl'
>>> _ = joblib.dump(clf, filename, compress=9)
>>> clf2 = joblib.load(filename)
>>> clf2
SGDClassifier(alpha=0.0001, class_weight=None, epsilon=0.1, eta0=0.0,
fit_intercept=True, learning_rate='optimal', loss='hinge', n_iter=5,
n_jobs=1, penalty='l2', power_t=0.5, rho=0.85, seed=0,
shuffle=False, verbose=0, warm_start=False)
>>> clf2.score(digits.data, digits.target)
0.9526989426822482
Edit: in Python 3.8+ it's now possible to use pickle for efficient pickling of object with large numerical arrays as attributes if you use pickle protocol 5 (which is not the default).
According to the Go spec, the order of iteration over a map is undefined, and may vary between runs of the program. In practice, not only is it undefined, it's actually intentionally randomized. This is because it used to be predictable, and the Go language developers didn't want people relying on unspecified behavior, so they intentionally randomized it so that relying on this behavior was impossible.
What you'll have to do, then, is pull the keys into a slice, sort them, and then range over the slice like this:
var m map[keyType]valueType
keys := sliceOfKeys(m) // you'll have to implement this
for _, k := range keys {
v := m[k]
// k is the key and v is the value; do your computation here
}

This can be set up on your tsconfig.json file, as it is a TS feature.
You can do like this:
"compilerOptions": {
"baseUrl": "src", // This must be specified if "paths" is.
...
"paths": {
"@app/*": ["app/*"],
"@config/*": ["app/_config/*"],
"@environment/*": ["environments/*"],
"@shared/*": ["app/_shared/*"],
"@helpers/*": ["helpers/*"]
},
...
Have in mind that the path where you want to refer to, it takes your baseUrl as the base of the route you are pointing to and it's mandatory as described on the doc.
The character '@' is not mandatory.
After you set it up on that way, you can easily use it like this:
import { Yo } from '@config/index';
the only thing you might notice is that the intellisense does not work in the current latest version, so I would suggest to follow an index convention for importing/exporting files.
https://www.typescriptlang.org/docs/handbook/module-resolution.html#path-mapping
Also you can edit your Run/Debug configuration and add clean
task.
Click on the Edit configuration
In the left list of available configurations choose your current configuration and then on the right side of the dialog window in the section Before launch press on plus sign and choose Run Gradle task
In the new window choose your gradle project and in the field Tasks type clean
.
Then move your gradle clean on top of Gradle-Aware make
pyspark.sql.Column.contains()
is only available in pyspark version 2.2 and above.
df.where(df.location.contains('google.com'))
For the simple answer, you can use Link
component from react-router
, instead of button
. There is ways to change the route in JS, but seems you don't need that here.
<span className="input-group-btn">
<Link to="/login" />Click to login</Link>
</span>
To do it programmatically in 1.0.x, you do like this, inside your clickHandler function:
this.history.pushState(null, 'login');
Taken from upgrade doc here
You should have this.history
placed on your route handler component by react-router
. If it child component beneath that mentioned in routes
definition, you may need pass that down further
You need to name the entity that holds the association to User. For example,
... INNER JOIN ug.user u ...
That's the "path" the error message is complaining about -- path from UserGroup to User entity.
Hibernate relies on declarative JOINs, for which the join condition is declared in the mapping metadata. This is why it is impossible to construct the native SQL query without having the path.
You just can put your query as a subquery:
SELECT avg(count)
FROM
(
SELECT COUNT (*) AS Count
FROM Table T
WHERE T.Update_time =
(SELECT MAX (B.Update_time )
FROM Table B
WHERE (B.Id = T.Id))
GROUP BY T.Grouping
) as counts
Edit: I think this should be the same:
SELECT count(*) / count(distinct T.Grouping)
FROM Table T
WHERE T.Update_time =
(SELECT MAX (B.Update_time)
FROM Table B
WHERE (B.Id = T.Id))
Extending from multiple classes is not allowed in java.. to prevent Deadly Diamond of death !
If your Service is started by your app then actually your service is running on main process. so when app is killed service will also be stopped. So what you can do is, send broadcast from onTaskRemoved
method of your service as follows:
Intent intent = new Intent("com.android.ServiceStopped");
sendBroadcast(intent);
and have an broadcast receiver which will again start a service. I have tried it. service restarts from all type of kills.
If IncomingHandler
class is not static, it will have a reference to your Service
object.
Handler
objects for the same thread all share a common Looper object, which they post messages to and read from.
As messages contain target Handler
, as long as there are messages with target handler in the message queue, the handler cannot be garbage collected. If handler is not static, your Service
or Activity
cannot be garbage collected, even after being destroyed.
This may lead to memory leaks, for some time at least - as long as the messages stay int the queue. This is not much of an issue unless you post long delayed messages.
You can make IncomingHandler
static and have a WeakReference
to your service:
static class IncomingHandler extends Handler {
private final WeakReference<UDPListenerService> mService;
IncomingHandler(UDPListenerService service) {
mService = new WeakReference<UDPListenerService>(service);
}
@Override
public void handleMessage(Message msg)
{
UDPListenerService service = mService.get();
if (service != null) {
service.handleMessage(msg);
}
}
}

None of the other answers helped me. Here's what worked for me. I'm using the tutorial-1 sample from opencv but I will be doing using the NDK in my project so I'm using the gradle-experimental plugin which has a different structure than the gradle plugin.
Android studio should be installed, the Android NDK should be installed via the Android SDK Manager, and the OpenCV Android SDK should be downloaded and unzipped.
This is in chunks of bash script to keep it compact but complete. It's also all on the command line because on of the big problems I had was that in-IDE instructions were obsolete as the IDE evolved.
First set the location of the root directory of the OpenCV SDK.
export OPENCV_SDK=/home/user/wip/OpenCV-2.4.11-android-sdk
cd $OPENCV_SDK
Create your gradle build files...
First the OpenCV library
cat > $OPENCV_SDK/sdk/java/build.gradle <<'==='
apply plugin: 'com.android.model.library'
model {
android {
compileSdkVersion = 23
buildToolsVersion = "23.0.2"
defaultConfig.with {
minSdkVersion.apiLevel = 8
targetSdkVersion.apiLevel = 23
}
}
android.buildTypes {
release {
minifyEnabled = false
}
debug{
minifyEnabled = false
}
}
android.sources {
main.manifest.source.srcDirs += "."
main.res.source.srcDirs += "res"
main.aidl.source.srcDirs += "src"
main.java.source.srcDirs += "src"
}
}
===
Then tell the tutorial sample what to label the library as and where to find it.
cat > $OPENCV_SDK/samples/tutorial-1-camerapreview/settings.gradle <<'==='
include ':openCVLibrary2411'
project(':openCVLibrary2411').projectDir = new File('../../sdk/java')
===
Create the build file for the tutorial.
cat > $OPENCV_SDK/samples/tutorial-1-camerapreview/build.gradle <<'==='
buildscript {
repositories {
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle-experimental:0.2.1'
}
}
allprojects {
repositories {
jcenter()
}
}
apply plugin: 'com.android.model.application'
model {
android {
compileSdkVersion = 23
buildToolsVersion = "23.0.2"
defaultConfig.with {
applicationId = "org.opencv.samples.tutorial1"
minSdkVersion.apiLevel = 8
targetSdkVersion.apiLevel = 23
}
}
android.sources {
main.manifest.source.srcDirs += "."
main.res.source.srcDirs += "res"
main.aidl.source.srcDirs += "src"
main.java.source.srcDirs += "src"
}
android.buildTypes {
release {
minifyEnabled = false
proguardFiles += file('proguard-rules.pro')
}
debug {
minifyEnabled = false
}
}
}
dependencies {
compile project(':openCVLibrary2411')
}
===
Your build tools version needs to be set correctly. Here's an easy way to see what you have installed. (You can install other versions via the Android SDK Manager). Change buildToolsVersion if you don't have 23.0.2.
echo "Your buildToolsVersion is one of: "
ls $ANDROID_HOME/build-tools
Change the environment variable on the first line to your version number
REP=23.0.2 #CHANGE ME
sed -i.bak s/23\.0\.2/${REP}/g $OPENCV_SDK/sdk/java/build.gradle
sed -i.bak s/23\.0\.2/${REP}/g $OPENCV_SDK/samples/tutorial-1-camerapreview/build.gradle
Finally, set up the correct gradle wrapper. Gradle needs a clean directory to do this.
pushd $(mktemp -d)
gradle wrapper --gradle-version 2.5
mv -f gradle* $OPENCV_SDK/samples/tutorial-1-camerapreview
popd
You should now be all set. You can now browse to this directory with Android Studio and open up the project.
Build the tutoral on the command line with the following command:
./gradlew assembleDebug
It should build your apk, putting it in ./build/outputs/apk
I do it like this:
(Shortened the code a bit)
public struct Age
{
public readonly int Years;
public readonly int Months;
public readonly int Days;
}
public Age( int y, int m, int d ) : this()
{
Years = y;
Months = m;
Days = d;
}
public static Age CalculateAge ( DateTime birthDate, DateTime anotherDate )
{
if( startDate.Date > endDate.Date )
{
throw new ArgumentException ("startDate cannot be higher then endDate", "startDate");
}
int years = endDate.Year - startDate.Year;
int months = 0;
int days = 0;
// Check if the last year, was a full year.
if( endDate < startDate.AddYears (years) && years != 0 )
{
years--;
}
// Calculate the number of months.
startDate = startDate.AddYears (years);
if( startDate.Year == endDate.Year )
{
months = endDate.Month - startDate.Month;
}
else
{
months = ( 12 - startDate.Month ) + endDate.Month;
}
// Check if last month was a complete month.
if( endDate < startDate.AddMonths (months) && months != 0 )
{
months--;
}
// Calculate the number of days.
startDate = startDate.AddMonths (months);
days = ( endDate - startDate ).Days;
return new Age (years, months, days);
}
// Implement Equals, GetHashCode, etc... as well
// Overload equality and other operators, etc...
}
Here is my cover fill solution (similar to background-size: cover, but it supports old IE browser)
<div class="imgContainer" style="height:100px; width:500px; overflow:hidden; background-color: black">
<img src="http://dev.isaacsonwebdevelopment.com/sites/development/files/views-slideshow-settings-jquery-cycle-custom-options-message.png" id="imgCat">
</div>
<script src="http://ajax.aspnetcdn.com/ajax/jQuery/jquery-1.11.3.min.js"></script>
<script>
$(window).load(function() {
var heightRate =$("#imgCat").height() / $("#imgCat").parent(".imgContainer").height();
var widthRate = $("#imgCat").width() / $("#imgCat").parent(".imgContainer").width();
if (window.console) {
console.log($("#imgCat").height());
console.log(heightRate);
console.log(widthRate);
console.log(heightRate > widthRate);
}
if (heightRate <= widthRate) {
$("#imgCat").height($("#imgCat").parent(".imgContainer").height());
} else {
$("#imgCat").width($("#imgCat").parent(".imgContainer").width());
}
});
</script>
Always use UTC:
For example I have a schedule component that takes in one parameter DATETIME. When I call this using a GET verb I use the following format where my incoming parameter name is scheduleDate.
Example:
https://localhost/api/getScheduleForDate?scheduleDate=2003-11-21T01:11:11Z
Similar to Rory's answer, with ECMA 5 you can now just call str.trim().length
instead of using a regular expression. If the resulting value is 0 you know you have a string that contains only spaces.
if (!str.trim().length) {
console.log('str is empty!');
}
You can read more about trim here.
Use below code:
// Variable to check
$email = "[email protected]";
// Remove all illegal characters from email
$email = filter_var($email, FILTER_SANITIZE_EMAIL);
// Validate e-mail
if (filter_var($email, FILTER_VALIDATE_EMAIL)) {
echo("Email is a valid email address");
} else {
echo("Oppps! Email is not a valid email address");
}
You would want to pass a pointer by reference if you have a need to modify the pointer rather than the object that the pointer is pointing to.
This is similar to why double pointers are used; using a reference to a pointer is slightly safer than using pointers.
Ctrl+P and Type "ext install cpptools" it will install everything you need to debug c and c++.
Debugging in VS code is very complete, but if you just need to compile and run: https://code.visualstudio.com/docs/languages/cpp
Look in the debugging section and it will explain everything
Inner join matches tables on keys, but outer join matches keys just for one side. For example when you use left outer join the query brings the whole left side table and matches the right side to the left table primary key and where there is not matched places null.
If the image isn't that big, and if there's a good chance you'll be re-using the image often, and if you don't have too many of them, and if the images are not secret (meaning it's no big deal if one user could potentially see another person's image)...
Lots of "if"s here, so there's a good chance this is a bad idea:
You can store the image bytes in Cache
for a short time, and make an image tag pointed toward an action method, which in turn reads from the cache and spits out your image. This will allow the browser to cache the image appropriately.
// In your original controller action
HttpContext.Cache.Add("image-" + model.Id, model.ImageBytes, null,
Cache.NoAbsoluteExpiration, TimeSpan.FromMinutes(1),
CacheItemPriority.Normal, null);
// In your view:
<img src="@Url.Action("GetImage", "MyControllerName", new{fooId = Model.Id})">
// In your controller:
[OutputCache(VaryByParam = "fooId", Duration = 60)]
public ActionResult GetImage(int fooId) {
// Make sure you check for null as appropriate, re-pull from DB, etc.
return File((byte[])HttpContext.Cache["image-" + fooId], "image/gif");
}
This has the added benefit (or is it a crutch?) of working in older browsers, where the inline images don't work in IE7 (or IE8 if larger than 32kB).
In addition to the good advice already given, I would add this:
It is probably best to avoid using require()
unless you actually will be using the value it returns e.g in some error checking loop such as given by thierry.
In most other cases it is better to use library()
, because this will give an error message at package loading time if the package is not available. require()
will just fail without an error if the package is not there. This is the best time to find out if the package needs to be installed (or perhaps doesn't even exist because it it spelled wrong). Getting error feedback early and at the relevant time will avoid possible headaches with tracking down why later code fails when it attempts to use library routines
Instead of using align-self: center
use align-items: center
.
There's no need to change flex-direction
or use text-align
.
Here's your code, with one adjustment, to make it all work:
ul {
height: 100%;
}
li {
display: flex;
justify-content: center;
/* align-self: center; <---- REMOVE */
align-items: center; /* <---- NEW */
background: silver;
width: 100%;
height: 20%;
}
The align-self
property applies to flex items. Except your li
is not a flex item because its parent – the ul
– does not have display: flex
or display: inline-flex
applied.
Therefore, the ul
is not a flex container, the li
is not a flex item, and align-self
has no effect.
The align-items
property is similar to align-self
, except it applies to flex containers.
Since the li
is a flex container, align-items
can be used to vertically center the child elements.
* {_x000D_
padding: 0;_x000D_
margin: 0;_x000D_
}_x000D_
html, body {_x000D_
height: 100%;_x000D_
}_x000D_
ul {_x000D_
height: 100%;_x000D_
}_x000D_
li {_x000D_
display: flex;_x000D_
justify-content: center;_x000D_
/* align-self: center; */_x000D_
align-items: center;_x000D_
background: silver;_x000D_
width: 100%;_x000D_
height: 20%;_x000D_
}
_x000D_
<ul>_x000D_
<li>This is the text</li>_x000D_
</ul>
_x000D_
Technically, here's how align-items
and align-self
work...
The align-items
property (on the container) sets the default value of align-self
(on the items). Therefore, align-items: center
means all flex items will be set to align-self: center
.
But you can override this default by adjusting the align-self
on individual items.
For example, you may want equal height columns, so the container is set to align-items: stretch
. However, one item must be pinned to the top, so it is set to align-self: flex-start
.
How is the text a flex item?
Some people may be wondering how a run of text...
<li>This is the text</li>
is a child element of the li
.
The reason is that text that is not explicitly wrapped by an inline-level element is algorithmically wrapped by an inline box. This makes it an anonymous inline element and child of the parent.
From the CSS spec:
9.2.2.1 Anonymous inline boxes
Any text that is directly contained inside a block container element must be treated as an anonymous inline element.
The flexbox specification provides for similar behavior.
Each in-flow child of a flex container becomes a flex item, and each contiguous run of text that is directly contained inside a flex container is wrapped in an anonymous flex item.
Hence, the text in the li
is a flex item.
When debugging optimized programs (which may be necessary if the bug doesn't show up in debug builds), you often have to understand assembly compiler generated.
In your particular case, return value of cpnd_find_exact_ckptinfo
will be stored in the register which is used on your platform for return values. On ix86
, that would be %eax
. On x86_64
: %rax
, etc. You may need to google for '[your processor] procedure calling convention' if it's none of the above.
You can examine that register in GDB
and you can set it. E.g. on ix86
:
(gdb) p $eax
(gdb) set $eax = 0
Get rid of the semicolon after WordGame
.
You really should have discovered this problem when the class was a lot smaller. When you're writing code, you should be compiling about every time you add half a dozen lines.
It's important to specify timeouts, especially when the server takes to respond. With pure Java, without using any dependency:
public static byte[] copyURLToByteArray(final String urlStr,
final int connectionTimeout, final int readTimeout)
throws IOException {
final URL url = new URL(urlStr);
final URLConnection connection = url.openConnection();
connection.setConnectTimeout(connectionTimeout);
connection.setReadTimeout(readTimeout);
try (InputStream input = connection.getInputStream();
ByteArrayOutputStream output = new ByteArrayOutputStream()) {
final byte[] buffer = new byte[8192];
for (int count; (count = input.read(buffer)) > 0;) {
output.write(buffer, 0, count);
}
return output.toByteArray();
}
}
Using dependencies, e.g., HC Fluent:
public byte[] copyURLToByteArray(final String urlStr,
final int connectionTimeout, final int readTimeout)
throws IOException {
return Request.Get(urlStr)
.connectTimeout(connectionTimeout)
.socketTimeout(readTimeout)
.execute()
.returnContent()
.asBytes();
}
This too took me sometime to figure out.
Solution:
To create a new Maven Project under the existing workspace, just have the "Use default Workspace location" ticked (Ignore what is in the grayed out location text input).
The name of the project will be determined by you Artifact Id in step 2 of the creation wizard.
Reasoning:
It was so confusing because in my case, because when I selected to create a new Maven Project: the default workspace loaction is ticked and directly proceeding it is the grayed out "Location" text input had the workspace location + the existing project I was looking at before choose to create a new Maven Project. (ie: Location = '[workspace path]/last looked at project')
So I unticked the default workspace location box and entered in '[workspace path]/new project', which didn't work because eclipse expects the [workspace path] to be different compared to the default path. (Otherwise we would of selected the default workspace check box).
That way it's simpler, where you pass the image and then pass the format.
private static string ImageToBase64(Image image)
{
var imageStream = new MemoryStream();
try
{
image.Save(imageStream, System.Drawing.Imaging.ImageFormat.Bmp);
imageStream.Position = 0;
var imageBytes = imageStream.ToArray();
var ImageBase64 = Convert.ToBase64String(imageBytes);
return ImageBase64;
}
catch (Exception ex)
{
return "Error converting image to base64!";
}
finally
{
imageStream.Dispose;
}
}
It looks like github has a simple UI for creating branches. I opened the branch drop-down and it prompts me to "Find or create a branch ...". Type the name of your new branch, then click the "create" button that appears.
To retrieve your new branch from github, use the standard git fetch
command.
I'm not sure this will help your underlying problem, though, since the underlying data being pushed to the server (the commit objects) is the same no matter what branch it's being pushed to.
Simple & clean. Only uses System.IO.FileSystem
- works like a charm:
string path = "C:/folder1/folder2/file.txt";
string folder = new DirectoryInfo(path).Name;
This works fine .. here btnAddCat is button id
$('#btnAddCat').click(function(){
var eventCategory=$("input[name=txtCategory]").val();
alert(eventCategory);
});
as above, but qualitatively:
private - least access, best encapsulation
protected - some access, moderate encapsulation
public - full access, no encapsulation
the less access you provide the fewer implementation details leak out of your objects. less of this sort of leakage means more flexibility (aka "looser coupling") in terms of changing how an object is implemented without breaking clients of the object. this is a truly fundamental thing to understand.
In my case, I was using a dependency scoped as <scope>test</scope>
. This made the class available at development time but, by at compile time, I got this message.
Turn the class scope for <scope>provided</scope>
solved the problem.

Addition to Mark Byers answer :
Sometimes you also want to insert Hardcoded details else there may be Unique constraint fail etc. So use following in such situation where you override some values of the columns.
INSERT INTO matrimony_domain_details (domain, type, logo_path)
SELECT 'www.example.com', type, logo_path
FROM matrimony_domain_details
WHERE id = 367
Here domain value is added by me me in Hardcoded way to get rid from Unique constraint.
IceForge's answer was pretty close, and is AFAIK the easiest solution to this problem. But it missed something, as it wasn't working (at least for me, it never actually displays the text).
In the end, you can't just set the "Visibility" property of the TextBlock to "Hidden" in order for it to be hidden when the combo box's selected item isn't null; you have to SET it that way by default (since you can't check not null in triggers, by using a Setter in XAML at the same place as the Triggers.
Here's the actual solution based on his, the missing Setter being placed just before the Triggers:
<ComboBox x:Name="combo"/>
<TextBlock Text="--Select Team--" IsHitTestVisible="False">
<TextBlock.Style>
<Style TargetType="TextBlock">
<Style.Setters>
<Setter Property="Visibility" Value="Hidden"/>
</Style.Setters>
<Style.Triggers>
<DataTrigger Binding="{Binding ElementName=combo,Path=SelectedItem}" Value="{x:Null}">
<Setter Property="Visibility" Value="Visible"/>
</DataTrigger>
</Style.Triggers>
</Style>
</TextBlock.Style>
</TextBlock>
use an unsigned long long (i.e. a 64 bit unit) to represent the system time:
typedef unsigned long long u64;
u64 u64useconds;
struct timeval tv;
gettimeofday(&tv,NULL);
u64useconds = (1000000*tv.tv_sec) + tv.tv_usec;
put the dll in system32 or syswow32 directory, and use appropriate regsvr32 to register it. wiered that even though it gave failed to register error, I rebooted my WIN 7 64 AND my vb app loaded the dll just fine!!
You are looking for the command scandir.
$path = '/tmp';
$files = scandir($path);
Following code will remove .
and ..
from the returned array from scandir
:
$files = array_diff(scandir($path), array('.', '..'));

Here you will get list of diffrent ways of applying the click event. You can select accordingly as suaitable or if your click is not working just try an alternative out of these.
$('.clickHere').click(function(){
// this is flat click. this event will be attatched
//to element if element is available in
//dom at the time when JS loaded.
// do your stuff
});
$('.clickHere').on('click', function(){
// same as first one
// do your stuff
})
$(document).on('click', '.clickHere', function(){
// this is diffrent type
// of click. The click will be registered on document when JS
// loaded and will delegate to the '.clickHere ' element. This is
// called event delegation
// do your stuff
});
$('body').on('click', '.clickHere', function(){
// This is same as 3rd
// point. Here we used body instead of document/
// do your stuff
});
$('.clickHere').off().on('click', function(){ //
// deregister event listener if any and register the event again. This
// prevents the duplicate event resistration on same element.
// do your stuff
})
To perfectly forward without chopping the absoluteURI
of the request and the Host
in the header:
server {
listen 35005;
location / {
rewrite ^(.*)$ "://$http_host$uri$is_args$args";
rewrite ^(.*)$ "http$uri$is_args$args" break;
proxy_set_header Host $host;
proxy_pass https://deploy.org.local:35005;
}
}

You can try the following library: http://code.google.com/p/android-screenshot-library/ Android Screenshot Library (ASL) enables to programmatically capture screenshots from Android devices without requirement of having root access privileges. Instead, ASL utilizes a native service running in the background, started via the Android Debug Bridge (ADB) once per device boot.
Have you tried to add a schema to xml catalog?
in eclipse to avoid the "no grammar constraints (dtd or xml schema) detected for the document." i use to add an xsd schema file to the xml catalog under
"Window \ preferences \ xml \ xml catalog \ User specified entries".
Click "Add" button on the right.
Example:
<?xml version="1.0" encoding="UTF-8"?>
<HolidayRequest xmlns="http://mycompany.com/hr/schemas">
<Holiday>
<StartDate>2006-07-03</StartDate>
<EndDate>2006-07-07</EndDate>
</Holiday>
<Employee>
<Number>42</Number>
<FirstName>Arjen</FirstName>
<LastName>Poutsma</LastName>
</Employee>
</HolidayRequest>
From this xml i have generated and saved an xsd under: /home/my_user/xsd/my_xsd.xsd
As Location: /home/my_user/xsd/my_xsd.xsd
As key type: Namespace name
As key: http://mycompany.com/hr/schemas
Close and reopen the xml file and do some changes to violate the schema, you should be notified
For accessing the height of the status bar for Android devices, we prefer a programmatic way to get it:
int resId = getResources().getIdentifier("status_bar_height", "dimen", "android");
if (resId > 0) {
result = getResources().getDimensionPixelSize(resId);
}
The variable result
gives the height in the pixel.
For more information about height of Title bar
, Navigation bar
and Content View
, kindly look on Android Device Screen Sizes.
jQuery.fn.extend({
zigzag: function () {
var text = $(this).text();
var zigzagText = '';
var toggle = true; //lower/uppper toggle
$.each(text, function(i, nome) {
zigzagText += (toggle) ? nome.toUpperCase() : nome.toLowerCase();
toggle = (toggle) ? false : true;
});
return zigzagText;
}
});
I had this issue where on a screen orientation change, the activity finished before the AsyncTask with the progress dialog completed. I seemed to resolve this by setting the dialog to null onPause()
and then checking this in the AsyncTask before dismissing.
@Override
public void onPause() {
super.onPause();
if ((mDialog != null) && mDialog.isShowing())
mDialog.dismiss();
mDialog = null;
}
... in my AsyncTask:
protected void onPreExecute() {
mDialog = ProgressDialog.show(mContext, "", "Saving changes...",
true);
}
protected void onPostExecute(Object result) {
if ((mDialog != null) && mDialog.isShowing()) {
mDialog.dismiss();
}
}
The basename
function should give you what you want:
Given a string containing a path to a file, this function will return the base name of the file.
For instance, quoting the manual's page:
<?php
$path = "/home/httpd/html/index.php";
$file = basename($path); // $file is set to "index.php"
$file = basename($path, ".php"); // $file is set to "index"
?>
Or, in your case:
$full = 'F:\Program Files\SSH Communications Security\SSH Secure Shell\Output.map';
var_dump(basename($full));
You'll get:
string(10) "Output.map"
I have written a little JavaScript library called balanced to help with this task. You can accomplish this by doing
balanced.matches({
source: source,
open: '(',
close: ')'
});
You can even do replacements:
balanced.replacements({
source: source,
open: '(',
close: ')',
replace: function (source, head, tail) {
return head + source + tail;
}
});
Here's a more complex and interactive example JSFiddle.
On the new Date(
) you can get the offset, to get the timezone name you may do:
new Date().toString().replace(/(.*\((.*)\).*)/, '$2');
you get the value between ()
in the end of the date, that is the name of the timezone.
I couldn't use the other solutions... What worked for me was installing LocalTunnel.net (https://github.com/danielrmz/localtunnel-net-client), and then using the resulting url on Facebook.
I had a more complicated query, and found that I had to use GROUP_CONCAT
in an outer query to get it to work:
SELECT DISTINCT userID
FROM event GROUP BY userID
HAVING count(distinct(cohort))=2);
SELECT GROUP_CONCAT(sub.userID SEPARATOR ', ')
FROM (SELECT DISTINCT userID FROM event
GROUP BY userID HAVING count(distinct(cohort))=2) as sub;
Hope this might help someone.
Yet another way in C++ is
struct Point
{
private:
int x;
int y;
public:
Point& setX(int xIn) { x = Xin; return *this;}
Point& setY(int yIn) { y = Yin; return *this;}
}
Point pt;
pt.setX(20).setY(20);
The following hack let's you sleep for 5 seconds
ping -n 6 127.0.0.1 > nul
Since ping waits a second between the pings, you have to specify one more than you need.
So this is an older question, but for those still looking for an answer, the CSS property Box-Sizing is priceless here:
-webkit-box-sizing: border-box; /* Safari/Chrome, other WebKit */
-moz-box-sizing: border-box; /* Firefox, other Gecko */
box-sizing: border-box;
It means that you can set the width of the Div to a percentage, and any border you add to the div will be included within that percentage. So, for example, the following would add the 1px border to the inside of the width of the div:
div { box-sizing:border-box; width:50%; border-right:1px solid #000; }
If you'd like more info: http://css-tricks.com/box-sizing/
For synchronous approach
const fs = require('fs')
fs.writeFileSync('file.json', JSON.stringify(jsonVariable));
I've used mingw on Linux to make Windows executables in C, I suspect C++ would work as well.
I have a project, ELLCC, that packages clang and other things as a cross compiler tool chain. I use it to compile clang (C++), binutils, and GDB for Windows. Follow the download link at ellcc.org for pre-compiled binaries for several Linux hosts.
In my case I mistakely imported Action into my combineEpics, rather than Epic...
Verify all the functions within combine Epics are epic funcitons

This is a working example of making ZIPs in PHP:
$zip = new ZipArchive();
$zip_name = time().".zip"; // Zip name
$zip->open($zip_name, ZipArchive::CREATE);
foreach ($files as $file) {
echo $path = "uploadpdf/".$file;
if(file_exists($path)){
$zip->addFromString(basename($path), file_get_contents($path));
}
else{
echo"file does not exist";
}
}
$zip->close();
Put in other words, this error is telling you that SQL Server does not know which B
to select from the group.
Either you want to select one specific value (e.g. the MIN
, SUM
, or AVG
) in which case you would use the appropriate aggregate function, or you want to select every value as a new row (i.e. including B
in the GROUP BY
field list).
Consider the following data:
ID A B 1 1 13 1 1 79 1 2 13 1 2 13 1 2 42
The query
SELECT A, COUNT(B) AS T1
FROM T2
GROUP BY A
would return:
A T1 1 2 2 3
which is all well and good.
However consider the following (illegal) query, which would produce this error:
SELECT A, COUNT(B) AS T1, B
FROM T2
GROUP BY A
And its returned data set illustrating the problem:
A T1 B 1 2 13? 79? Both 13 and 79 as separate rows? (13+79=92)? ...? 2 3 13? 42? ...?
However, the following two queries make this clear, and will not cause the error:
Using an aggregate
SELECT A, COUNT(B) AS T1, SUM(B) AS B
FROM T2
GROUP BY A
would return:
A T1 B 1 2 92 2 3 68
Adding the column to the GROUP BY
list
SELECT A, COUNT(B) AS T1, B
FROM T2
GROUP BY A, B
would return:
A T1 B 1 1 13 1 1 79 2 2 13 2 1 42

class Tree(dict):

def __init__(self, data={}):
for k, data in data.items():
if isinstance(data, dict):

else:
self[k] = data
works as a dictionary, but provides as many nested dicts you want. Try the following:
your_tree = Tree()
your_tree['a']['1']['x'] = '@'
your_tree['a']['1']['y'] = '#'
your_tree['a']['2']['x'] = '$'
your_tree['a']['3'] = '%'
your_tree['b'] = '*'
will deliver a nested dict ... which works as a tree indeed.
{'a': {'1': {'x': '@', 'y': '#'}, '2': {'x': '$'}, '3': '%'}, 'b': '*'}
... If you have already a dict, it will cast each level to a tree:
d = {'foo': {'amy': {'what': 'runs'} } }
tree = Tree(d)
print(d['foo']['amy']['what']) # returns 'runs'
d['foo']['amy']['when'] = 'now' # add new branch
In this way, you can keep edit/add/remove each dict level as you wish. All the dict methods for traversal etc, still apply.
I wrote a function what works fine with every instance of Objects (Arrays are those).
Object.prototype.toArray = function()
{
if(!this)
{
return null;
}
var c = [];
for (var key in this)
{
if ( ( this instanceof Array && this.constructor === Array && key === 'length' ) || !this.hasOwnProperty(key) )
{
continue;
}
c.push(this[key]);
}
return c;
};
Usage:
var a = [ 1, 2, 3 ];
a[11] = 4;
a["js"] = 5;
console.log(a.toArray());
var b = { one: 1, two: 2, three: 3, f: function() { return 4; }, five: 5 };
b[7] = 7;
console.log(b.toArray());
Output:
> [ 1, 2, 3, 4, 5 ]
> [ 7, 1, 2, 3, function () { return 4; }, 5 ]
It may be useful for anyone.
Dictionary is a key value pair. Catch Key by

Shared service is a good solution for this issue. If you want to store some activity information too, you can add Shared Service to your main modules (app.module) provider list.
@NgModule({
imports: [
...
],
bootstrap: [
AppComponent
],
declarations: [
AppComponent,
],
providers: [
SharedService,
...
]
});
Then you can directly provide it to your components,
constructor(private sharedService: SharedService)
With Shared Service you can either use functions or you can create a Subject to update multiple places at once.
@Injectable()
export class SharedService {
public clickedItemInformation: Subject<string> = new Subject();
}
In your list component you can publish clicked item information,
this.sharedService.clikedItemInformation.next("something");
and then you can fetch this information at your detail component:
this.sharedService.clikedItemInformation.subscribe((information) => {
// do something
});
Obviously, the data that list component shares can be anything. Hope this helps.

This error can also occur if your interface name is different than the file it is contained in. Read about ES6 modules for details. If the SignInComponent
was an interface, as was in my case, then
SignInComponent
should be in a file named SignInComponent.ts
.
It's the same as the Objective-C API, but uses Swift's syntax.
Swift 4.2 & Swift 5:
NotificationCenter.default.addObserver(
self,
selector: #selector(self.batteryLevelChanged),
name: UIDevice.batteryLevelDidChangeNotification,
object: nil)
If your observer does not inherit from an Objective-C object, you must prefix your method with @objc
in order to use it as a selector.
@objc private func batteryLevelChanged(notification: NSNotification){
//do stuff using the userInfo property of the notification object
}
See NSNotificationCenter Class Reference, Interacting with Objective-C APIs
I suggest
if (checkbox.IsChecked == true)
{
//do something
}
Hope it's helpful ^^
I had this error running php-fpm in a chroot jail. I tried creating etc/php.ini and /usr/share/zoneinfo in the chroot directory, but it just didn't work. I even tried strace-ing the php-fpm daemons to see what file they were missing - nothing jumped out.
So in case Google brings you here because you get this error when using php-fpm configured for chroot, you can probably fix it by adding this line to /etc/php-fpm.d/www.conf
in the ENV section:
env[TZ] = America/New_York
A php-fpm restart is normally required for it to take effect. Hope this helps somebody out there.
A little off topic, but if you want to migrate the data to a new table, and the possible duplicates are in the original table, and the column possibly duplicated is not an id, a GROUP BY
will do:
INSERT INTO TABLE_2
(name)
SELECT t1.name

In the particular case where you know the number of positions that you want to remove from the dataframe column, you can use string indexing inside a lambda function to get rid of that parts:
Last character:
data['result'] = data['result'].map(lambda x: str(x)[:-1])
First two characters:
data['result'] = data['result'].map(lambda x: str(x)[2:])
Edit: With thanks to cocoafan: This situation is muddled up by the fact that NSView
and UIView
handle things differently. For NSView
(desktop Mac development only), you can simply use the following:
[someNSView setSubviews:[NSArray array]];
For UIView
(iOS development only), you can safely use makeObjectsPerformSelector:
because the subviews
property will return a copy of the array of subviews:
[[someUIView subviews]
makeObjectsPerformSelector:@selector(removeFromSuperview)];
Thank you to Tommy for pointing out that makeObjectsPerformSelector:
appears to modify the subviews
array while it is being enumerated (which it does for NSView
, but not for UIView
).
Please see this SO question for more details.
Note: Using either of these two methods will remove every view that your main view contains and release them, if they are not retained elsewhere. From Apple's documentation on removeFromSuperview:
If the receiver’s superview is not nil, this method releases the receiver. If you plan to reuse the view, be sure to retain it before calling this method and be sure to release it as appropriate when you are done with it or after adding it to another view hierarchy.
With Unicode we can do it easily,but if want to change color of bullet, I tried with colored bullet image and set it as drawable left and it worked
<TextView
android:text="Hello bullet"
android:drawableLeft="@drawable/bulleticon" >
</TextView>
I've just come up with a fairly reasonable solution that lets you define the files to build and have directories be automatically created. First, define a variable ALL_TARGET_FILES
that holds the file name of every file that your makefile will be build. Then use the following code:
define depend_on_dir
$(1): | $(dir $(1))
ifndef $(dir $(1))_DIRECTORY_RULE_IS_DEFINED
$(dir $(1)):
mkdir -p $$@
$(dir $(1))_DIRECTORY_RULE_IS_DEFINED := 1
endif
endef
$(foreach file,$(ALL_TARGET_FILES),$(eval $(call depend_on_dir,$(file))))
Here's how it works. I define a function depend_on_dir
which takes a file name and generates a rule that makes the file depend on the directory that contains it and then defines a rule to create that directory if necessary. Then I use foreach
to call
this function on each file name and eval
the result.
Note that you'll need a version of GNU make that supports eval
, which I think is versions 3.81 and higher.
Another good way of dealing with Lion's hidden scroll bars is to display a prompt to scroll down. It doesn't work with small scroll areas such as text fields but well with large scroll areas and keeps the overall style of the site. One site doing this is http://versusio.com, just check this example page and wait 1.5 seconds to see the prompt:
http://versusio.com/en/samsung-galaxy-nexus-32gb-vs-apple-iphone-4s-64gb
The implementation isn't hard but you have to take care, that you don't display the prompt when the user has already scrolled.
You need jQuery + Underscore and
$(window).scroll
to check if the user already scrolled by himself,
_.delay()
to trigger a delay before you display the prompt -- the prompt shouldn't be to obtrusive
$('#prompt_div').fadeIn('slow')
to fade in your prompt and of course
$('#prompt_div').fadeOut('slow')
to fade out when the user scrolled after he saw the prompt
In addition, you can bind Google Analytics events to track user's scrolling behavior.
You can use this magic Spring Test annotation :
@TestPropertySource(properties = { "my.spring.property=20" })
see org.springframework.test.context.TestPropertySource
For example, this is the test class :
@ContextConfiguration(classes = { MyTestClass.Config.class })
@TestPropertySource(properties = { "my.spring.property=20" })
public class MyTestClass {
public static class Config {
@Bean
MyClass getMyClass() {
return new MyClass ();
}
}
@Resource
private MyClass myClass ;
@Test
public void myTest() {
...
And this is the class with the property :
@Component
public class MyClass {
@Value("${my.spring.property}")
private int mySpringProperty;
...
There are a number of ways to go about this. One way would be to enter the date 8/1/2013
manually in the first cell (say A1
for example's sake) and then in B1
type the following formula (and then drag it across):
=DATE(YEAR(A1),MONTH(A1)+1,1)
Since you only want to see month and year, you can format accordingly using the different custom date formats available.
The format you're looking for is YY-Mmm
.
See ?merge
:
the name "row.names" or the number 0 specifies the row names.
Example:
R> de <- merge(d, e, by=0, all=TRUE) # merge by row names (by=0 or by="row.names")
R> de[is.na(de)] <- 0 # replace NA values
R> de
Row.names a b c d e f g h i j k l m n o p q r s

The only benefit that I can think of is Transactional feature, rest all can be done by using Kafka
Set up the text box with placeholder text in a soft color...
public MainWindow ( )
{
InitializeComponent ( );
txtInput.Text = "Type something here...";
txtInput.Foreground = Brushes.DimGray;
}
When the text box gets the focus, clear it and change the text color
private void txtInput_GotFocus ( object sender, EventArgs e )
{
MessageBox.Show ( "got focus" );
txtInput.Text = "";
txtInput.Foreground = Brushes.Red;
}
First approach with Windows Service is not easy..
A long time ago, I wrote a C# service.
This is the logic of the Service class (tested, works fine):
namespace MyServiceApp
{
public class MyService : ServiceBase
{
private System.Timers.Timer timer;
protected override void OnStart(string[] args)
{
this.timer = new System.Timers.Timer(30000D); // 30000 milliseconds = 30 seconds
this.timer.AutoReset = true;
this.timer.Elapsed += new System.Timers.ElapsedEventHandler(this.timer_Elapsed);
this.timer.Start();
}
protected override void OnStop()
{
this.timer.Stop();
this.timer = null;
}
private void timer_Elapsed(object sender, System.Timers.ElapsedEventArgs e)
{
MyServiceApp.ServiceWork.Main(); // my separate static method for do work
}
public MyService()
{
this.ServiceName = "MyService";
}
// service entry point
static void Main()
{
System.ServiceProcess.ServiceBase.Run(new MyService());
}
}
}
I recommend you write your real service work in a separate static method (why not, in a console application...just add reference to it), to simplify debugging and clean service code.
Make sure the interval is enough, and write in log ONLY in OnStart and OnStop overrides.
Hope this helps!
Only checked
and checked="checked"
are valid. Your other options depend on error recovery in browsers.
checked="yes"
and checked="true"
are particularly bad as they imply that checked="no"
and checked="false"
will set the default state to be unchecked … which they will not.
jsonVariable = {}
for(i=1; i<3; i++) {
var jsonKey = i+'name';
jsonVariable[jsonKey] = 'name1'
}
this will be similar to
jsonVariable = {
1name : 'name1'
2name : 'name1'
}
<div data-ng-init="featureClass=false"
data-ng-click="featureClass=!featureClass"
data-ng-class="{'active': featureClass}">
Click me to toggle my class!
</div>
Analogous to jQuery's toggleClass
method, this is a way to toggle the active
class on/off when the element is clicked.

If you not commit your merge, then just double click on another branch (=checkout) and when sourcetree ask you about discarding all changes then agree
In class A
, set value for key:
let text = "hai"
UserDefaults.standard.setValue(text, forKey: "textValue")
In class B
, get the value for the text using the key which declared in class A
and assign it to respective variable which you need:
var valueOfText = UserDefaults.value(forKey: "textValue")
The default values for minOccurs
and maxOccurs
are 1. Thus:
<xsd:element minOccurs="1" name="asdf"/>
cardinality is [1-1] Note: if you specify only minOccurs attribute, it can't be greater than 1, because the default value for maxOccurs is 1.
<xsd:element minOccurs="5" maxOccurs="2" name="asdf"/>
invalid
<xsd:element maxOccurs="2" name="asdf"/>
cardinality is [1-2] Note: if you specify only maxOccurs attribute, it can't be smaller than 1, because the default value for minOccurs is 1.
<xsd:element minOccurs="0" maxOccurs="0"/>
is a valid combination which makes the element prohibited.

To summarize the other answers, for general use:
if [ foo ]; then
a; b
elif [ bar ]; then
c; d
else
e; f
fi
if [ foo ]; then a && b; elif [ bar ]; c && d; else e && f; fi
( foo && a && b ) || ( bar && c && d ) || e && f;
Remember that the AND and OR operators evaluate whether or not the result code of the previous operation was equal to true/success (0
). So if a custom function returns something else (or nothing at all), you may run into problems with the AND/OR shorthand. In such cases, you may want to replace something like ( a && b )
with ( [ a == 'EXPECTEDRESULT' ] && b )
, etc.
Also note that (
and [
are technically commands, so whitespace is required around them.
Instead of a group of &&
statements like then a && b; else
, you could also run statements in a subshell like then $( a; b ); else
, though this is less efficient. The same is true for doing something like result1=$( foo; a; b ); result2=$( bar; c; d ); [ "$result1" -o "$result2" ]
instead of ( foo && a && b ) || ( bar && c && d )
. Though at that point you'd be getting more into less-compact, multi-line stuff anyway.
Atom does not have a specific comment-block function, but if you select more rows and then use the normal ctrl-/ (Windows or Linux) cmd-/ (Mac), it will comment all the lines.
Not entirelly sure if it is a BUG(Tested Firefox 32.0.3 and Chrome 38.0.2125.101), but the following code will fail on Brazil (-3 GMT):
Date.prototype.shiftDays = function(days){
days = parseInt(days, 10);
this.setDate(this.getDate() + days);
return this;
}
$date = new Date(2014, 9, 16,0,1,1);
$date.shiftDays(1);
console.log($date+"");
$date.shiftDays(1);
console.log($date+"");
$date.shiftDays(1);
console.log($date+"");
$date.shiftDays(1);
console.log($date+"");
Result:
Fri Oct 17 2014 00:01:01 GMT-0300
Sat Oct 18 2014 00:01:01 GMT-0300
Sat Oct 18 2014 23:01:01 GMT-0300
Sun Oct 19 2014 23:01:01 GMT-0200
Adding one Hour to the date, will make it work perfectly (but does not solve the problem).
$date = new Date(2014, 9, 16,0,1,1);
Result:
Fri Oct 17 2014 01:01:01 GMT-0300
Sat Oct 18 2014 01:01:01 GMT-0300
Sun Oct 19 2014 01:01:01 GMT-0200

but what i am doing is purely synchronous
You could use HttpClient
for synchronous requests just fine:
using (var client = new HttpClient())
{
var response = client.GetAsync("http://google.com").Result;
if (response.IsSuccessStatusCode)
{
var responseContent = response.Content;
// by calling .Result you are synchronously reading the result
string responseString = responseContent.ReadAsStringAsync().Result;
Console.WriteLine(responseString);
}
}
As far as why you should use HttpClient
over WebRequest
is concerned, well, HttpClient
is the new kid on the block and could contain improvements over the old client.

You can index into a string in C# like an array, and you get the character at that index.
Example:
In Java, you would say
str.charAt(8);
In C#, you would say
str[8];
I know this is old, but just to make it clear, there is an explanation of each in the official android documentation:
from http://developer.android.com/tools/projects/index.html
assets/
This is empty. You can use it to store raw asset files. Files that you save here are compiled into an .apk file as-is, and the original filename is preserved. You can navigate this directory in the same way as a typical file system using URIs and read files as a stream of bytes using the AssetManager. For example, this is a good location for textures and game data.
res/raw/
For arbitrary raw asset files. Saving asset files here instead of in the assets/ directory only differs in the way that you access them. These files are processed by aapt and must be referenced from the application using a resource identifier in the R class. For example, this is a good place for media, such as MP3 or Ogg files.
:w
- Write a file.
!sudo
- Call shell sudo command.
tee
- The output of write (vim :w) command redirected using tee. The % is nothing but current file name i.e. /etc/apache2/conf.d/mediawiki.conf. In other words tee command is run as root and it takes standard input and write it to a file represented by %. However, this will prompt to reload file again (hit L to load changes in vim itself):
