Say the 1st date is in A1 cell
& the 2nd date is in B1 cell
Make sure that the cell type of both A1
& B1
is DATE
.
Then simply put the following formula in C1:
=A1-B1
The result of this formula may look funny to you.
Then Change the Cell type of C1
to GENERAL
.
It will give you the difference in Days.
You can also use this formula to get the remaining days of year or change the formula as you need:
=365-(A1-B1)
Not so hard:
#include <thread>
void Test::runMultiThread()
{
std::thread t1(&Test::calculate, this, 0, 10);
std::thread t2(&Test::calculate, this, 11, 20);
t1.join();
t2.join();
}
If the result of the computation is still needed, use a future instead:
#include <future>
void Test::runMultiThread()
{
auto f1 = std::async(&Test::calculate, this, 0, 10);
auto f2 = std::async(&Test::calculate, this, 11, 20);
auto res1 = f1.get();
auto res2 = f2.get();
}
In the case of sentences with uppercase - lowercase letters, We can use BINARY REPACE
UPDATE `table_1` SET `field_1` = BINARY REPLACE(`field_1`, 'find_string', 'replace_string')
public static void ReminderDigints(decimal? number, out decimal? Value, out decimal? Reminder)
{
Reminder = null;
Value = null;
if (number.HasValue)
{
Value = Math.Floor(number.Value);
Reminder = (number - Math.Truncate(number.Value));
}
}
decimal? number= 50.55m;
ReminderDigints(number, out decimal? Value, out decimal? Reminder);
mysql_*
extension has been deprecated in 2013 and removed completely from PHP in 2018. You have two alternatives PDO or MySQLi.
The simpler option is PDO which has a neat helper function fetchColumn()
:
$stmt = $pdo->prepare("SELECT id FROM Users WHERE username=?");
$stmt->execute([ $_GET["username"] ]);
$value = $stmt->fetchColumn();
You can do the same with MySQLi, but it is more complicated:
$stmt = $mysqliConn->prepare('SELECT id FROM Users WHERE username=?');
$stmt->bind_param("s", $_GET["username"]);
$stmt->execute();
$data = $stmt->get_result()->fetch_assoc();
$value = $data ? $data['id'] : null;
fetch_assoc()
could return NULL if there are no rows returned from the DB, which is why I check with ternary if there was any data returned.

The and operator in a selector is just an empty string, and the or operator is the comma.
There is however no grouping or priority, so you have to repeat one of the conditions:
a=$('[myc=blue][myid="1"],[myc=blue][myid="3"]');
In Python whitespace is significant. The function ends when the indentation becomes smaller (less).
def f():
pass # first line
pass # second line
pass # <-- less indentation, not part of function f.
Note that one-line functions can be written without indentation, on one line:
def f(): pass
And, then there is the use of semi-colons, but this is not recommended:
def f(): pass; pass
The three forms above show how the end of a function is defined syntactically. As for the semantics, in Python there are three ways to exit a function:
Using the return
statement. This works the same as in any other imperative programming language you may know.
Using the yield
statement. This means that the function is a generator. Explaining its semantics is beyond the scope of this answer. Have a look at Can somebody explain me the python yield statement?
By simply executing the last statement. If there are no more statements and the last statement is not a return
statement, then the function exists as if the last statement were return None
. That is to say, without an explicit return
statement a function returns None
. This function returns None
:
def f():
pass
And so does this one:
def f():

FileZilla does not have any command line arguments (nor any other way) that allow an automatic transfer.
Some references:
Though you can use any other client that allows automation.
You have not specified, what protocol you are using. FTP or SFTP? You will definitely be able to use WinSCP, as it supports all protocols that FileZilla does (and more).
Combine WinSCP scripting capabilities with Windows Scheduler:
A typical WinSCP script for upload (with SFTP) looks like:
open sftp://user:[email protected]/ -hostkey="ssh-rsa 2048 xxxxxxxxxxx...="
put c:\mypdfs\*.pdf /home/user/
close
With FTP, just replace the sftp://
with the ftp://
and remove the -hostkey="..."
switch.
Similarly for download: How to schedule an automatic FTP download on Windows?
WinSCP can even generate a script from an imported FileZilla session.
For details, see the guide to FileZilla automation.
(I'm the author of WinSCP)
Another option, if you are using SFTP, is the psftp.exe
client from PuTTY suite.
Maybe a much simpler way? Just adding to the list of answers here:
@for /f "tokens=1,* delims=: " %%a in ('sc queryex state=Inactive') do net start "%%b"
You can sort by multiple values simply by appending the values into a string and comparing the strings. It is helpful to add a split key character to prevent runoff from one key to the next.
const arr = [
{ a: 1, b: 'a', c: 3 },
{ a: 2, b: 'a', c: 5 },
{ a: 1, b: 'b', c: 4 },
{ a: 2, b: 'a', c: 4 }
]
function sortBy (arr, keys, splitKeyChar='~') {
return arr.sort((i1,i2) => {
const sortStr1 = keys.reduce((str, key) => str + splitKeyChar+i1[key], '')
const sortStr2 = keys.reduce((str, key) => str + splitKeyChar+i2[key], '')
return sortStr1.localeCompare(sortStr2)
})
}
console.log(sortBy(arr, ['a', 'b', 'c']))
_x000D_
You can also use Recursion to do this. It is a bit more complex than the String Appending Method but it allows you to do ASC and DESC on the key level. I'm commenting on each section as it is a bit more complex.
There are a few commented out tests to show and verify the sorting works with a mixture of order and default order.
const arr = [
{ a: 1, b: 'a', c: 3 },
{ a: 2, b: 'a', c: 5 },
{ a: 1, b: 'b', c: 4 },
{ a: 2, b: 'a', c: 4 }
]
function sortBy (arr, keys) {
return arr.sort(function sort (i1,i2, sKeys=keys) {
// Get order and key based on structure
const compareKey = (sKeys[0].key) ? sKeys[0].key : sKeys[0];
const order = sKeys[0].order || 'ASC'; // ASC || DESC
// Calculate compare value and modify based on order
let compareValue = i1[compareKey].toString().localeCompare(i2[compareKey].toString())
compareValue = (order.toUpperCase() === 'DESC') ? compareValue * -1 : compareValue
// See if the next key needs to be considered
const checkNextKey = compareValue === 0 && sKeys.length !== 1
// Return compare value
return (checkNextKey) ? sort(i1, i2, sKeys.slice(1)): compareValue;
})
}
// console.log(sortBy(arr, ['a', 'b', 'c']))
console.log(sortBy(arr, [{key:'a',order:'desc'}, 'b', 'c']))
// console.log(sortBy(arr, ['a', 'b', {key:'c',order:'desc'}]))
// console.log(sortBy(arr, ['a', {key:'b',order:'desc'}, 'c']))
// console.log(sortBy(arr, [{key:'a',order:'asc'}, {key:'b',order:'desc'}, {key:'c',order:'desc'}]))

The common way of doing this is to transform the documents into TF-IDF vectors and then compute the cosine similarity between them. Any textbook on information retrieval (IR) covers this. See esp. Introduction to Information Retrieval, which is free and available online.
TF-IDF (and similar text transformations) are implemented in the Python packages Gensim and scikit-learn. In the latter package, computing cosine similarities is as easy as
from sklearn.feature_extraction.text import TfidfVectorizer
documents = [open(f) for f in text_files]
tfidf = TfidfVectorizer().fit_transform(documents)
# no need to normalize, since Vectorizer will return normalized tf-idf
pairwise_similarity = tfidf * tfidf.T
or, if the documents are plain strings,
>>> corpus = ["I'd like an apple",
... "An apple a day keeps the doctor away",
... "Never compare an apple to an orange",
... "I prefer scikit-learn to Orange",
... "The scikit-learn docs are Orange and Blue"]
>>> vect = TfidfVectorizer(min_df=1, stop_words="english")
>>> tfidf = vect.fit_transform(corpus)
>>> pairwise_similarity = tfidf * tfidf.T
though Gensim may have more options for this kind of task.
See also this question.
[Disclaimer: I was involved in the scikit-learn TF-IDF implementation.]
From above, pairwise_similarity
is a Scipy sparse matrix that is square in shape, with the number of rows and columns equal to the number of documents in the corpus.
>>> pairwise_similarity
<5x5 sparse matrix of type '<class 'numpy.float64'>'
with 17 stored elements in Compressed Sparse Row format>
You can convert the sparse array to a NumPy array via .toarray()
or .A
:
>>> pairwise_similarity.toarray()
array([[1. , 0.17668795, 0.27056873, 0. , 0. ],
[0.17668795, 1. , 0.15439436, 0. , 0. ],
[0.27056873, 0.15439436, 1. , 0.19635649, 0.16815247],
[0. , 0. , 0.19635649, 1. , 0.54499756],
[0. , 0. , 0.16815247, 0.54499756, 1. ]])
Let's say we want to find the document most similar to the final document, "The scikit-learn docs are Orange and Blue". This document has index 4 in corpus
. You can find the index of the most similar document by taking the argmax of that row, but first you'll need to mask the 1's, which represent the similarity of each document to itself. You can do the latter through np.fill_diagonal()
, and the former through np.nanargmax()
:
>>> import numpy as np
>>> arr = pairwise_similarity.toarray()
>>> np.fill_diagonal(arr, np.nan)
>>> input_doc = "The scikit-learn docs are Orange and Blue"
>>> input_idx = corpus.index(input_doc)
>>> input_idx
4
>>> result_idx = np.nanargmax(arr[input_idx])
>>> corpus[result_idx]
'I prefer scikit-learn to Orange'
Note: the purpose of using a sparse matrix is to save (a substantial amount of space) for a large corpus & vocabulary. Instead of converting to a NumPy array, you could do:
>>> n, _ = pairwise_similarity.shape
>>> pairwise_similarity[np.arange(n), np.arange(n)] = -1.0
>>> pairwise_similarity[input_idx].argmax()

You are inside a namespace
so you should use \Exception
to specify the global namespace:
try {
$this->buildXMLHeader();
} catch (\Exception $e) {
return $e->getMessage();
}
In your code you've used catch (Exception $e)
so Exception
is being searched in/as:
App\Services\PayUService\Exception
Since there is no Exception
class inside App\Services\PayUService
so it's not being triggered. Alternatively, you can use a use
statement at the top of your class like use Exception;
and then you can use catch (Exception $e)
.
To get an attribute to show a specific value based on a boolean check, or be omitted entirely if the boolean check failed, I used the following:
ng-attr-example="{{params.type == 'test' ? 'itWasTest' : undefined }}"
Example usage:
<div ng-attr-class="{{params.type == 'test' ? 'itWasTest' : undefined }}">
Would output <div class="itWasTest">
or <div>
based on the value of params.type
All the above answers are correct, but I noticed something very important. Leaving a space between the variable and the equal sign might result in a problem. For example, (?variablename =value)
My own version of Kim T's code above which combines with some jQuery and allows for targeting of specific iframes.
$(function() {
callPlayer($('#iframe')[0], 'unMute');
});
function callPlayer(iframe, func, args) {
if ( iframe.src.indexOf('youtube.com/embed') !== -1) {
iframe.contentWindow.postMessage( JSON.stringify({
'event': 'command',
'func': func,
'args': args || []
} ), '*');
}
}
Here is the HTML snippet:
<td><iframe name="idFrame" id="idFrame" src="chat.txt" width="468" height="300"></iframe></td>
And my Javascript code:
window.onload = function(){
setInterval(function(){
parent.frames['idFrame'].location.href = "chat.txt";
},1000);}
Bootstrap uses the variable:
$font-size-base: 1rem; // Assumes the browser default, typically 16px
I don't recommend mucking with this, but you can. Best practice is to override the browser default base font size with:
html {
font-size: 14px;
}
Bootstrap will then take that value and use it via rems to set values for all kinds of things.
There is no built in construct in C#/.NET, but you can easily add your own extension method for this:
public static class ExtensionsForInt32
{
public static bool IsBetween (this int val, int low, int high)
{
return val > low && val < high;
}
}
Which can be used like:
if (5.IsBetween (0, 10)) { /* Do something */ }
If min value in array, you can try like:
>>> mydict = {"a": -1.5, "b": -1000.44, "c": -3}
>>> min(mydict.values())
-1000.44
The object (i.e. destination variable) for the AddDays method can't be the same as the source.
Instead of:
DateTime today = DateTime.Today;
today.AddDays(-7);
Try this instead:
DateTime today = DateTime.Today;
DateTime sevenDaysEarlier = today.AddDays(-7);
As far as I can tell, two things:
np.insert can also be used for the purpose
import numpy as np
a = np.array([[1, 3, 4],
[1, 2, 3],
[1, 2, 1]])
x = 5
index = 3 # the position for x to be inserted before
np.insert(a, index, x, axis=1)
array([[1, 3, 4, 5],
[1, 2, 3, 5],
[1, 2, 1, 5]])
index
can also be a list
/tuple
>>> index = [1, 1, 3] # equivalently (1, 1, 3)
>>> np.insert(a, index, x, axis=1)
array([[1, 5, 5, 3, 4, 5],
[1, 5, 5, 2, 3, 5],
[1, 5, 5, 2, 1, 5]])
or a slice
>>> index = slice(0, 3)
>>> np.insert(a, index, x, axis=1)
array([[5, 1, 5, 3, 5, 4],
[5, 1, 5, 2, 5, 3],
[5, 1, 5, 2, 5, 1]])
You can use:
echo '<?php if(function_exists("my_func")) echo "function exists"; ' | php
The short tag "< ?=" can be helpful too:
echo '<?= function_exists("foo") ? "yes" : "no";' | php
echo '<?= 8+7+9 ;' | php
The closing tag "?>" is optional, but don't forget the final ";"!
What about using something like mod_proxy? Then it looks to your browser like the requests are going to the same server, but they're really being forwarded to another server.
Try using COUNT function like this
=IF(COUNT(SEARCH({"Romney","Obama","Gingrich"},C1)),1,"")
Note that you don't need the wildcards (as teylyn says) and unless there's a specific reason "1" doesn't need quotes (in fact that makes it a text value)
Even if this question has resolved, I want to add my advice about that.... since as developer I ignored.
Is important to know that we're talking about MSSQL xp_cmdshell enabled is critical to security, as indicated in the message warning:
Blockquote SQL Server blocked access to procedure 'sys.xp_cmdshell' of component 'xp_cmdshell' because this component is turned off as part of the security configuration for this server. [...]
Leaving the service enabled is a kind of weakness, that for example in a web-app could reflect and execute commands SQL from an attacker.
The popular CWE-89: SQL Injection
it could be weakness in the our software, and therefore these type of scenarios could pave the way to possible attacks, such as CAPEC-108: Command Line Execution through SQL Injection
I hope to have done something pleasant, we Developers and Engineer do things with awareness and we will be safer!
An independent parent is the best practice for sharing configuration and options across otherwise uncoupled components. Apache has a parent pom project to share legal notices and some common packaging options.
If your top-level project has real work in it, such as aggregating javadoc or packaging a release, then you will have conflicts between the settings needed to do that work and the settings you want to share out via parent. A parent-only project avoids that.
A common pattern (ignoring #1 for the moment) is have the projects-with-code use a parent project as their parent, and have it use the top-level as a parent. This allows core things to be shared by all, but avoids the problem described in #2.
The site plugin will get very confused if the parent structure is not the same as the directory structure. If you want to build an aggregate site, you'll need to do some fiddling to get around this.
Apache CXF is an example the pattern in #2.
For Visual Studio Code:
launch.json
file"args": ["some argument", "another one"],

Try the following:

This will give the index of the row which is currently selected.
Hope this helps
If both the list are too big and when we use lamda expression then it will take a long time to fetch . Better to use linq in this case to fetch parameters list:
var items = (from x in parameters
join y in myStrings on x.Source equals y
select x)
.ToList();
to use sendmail from the shell script

) to the beginning of the entry. Even if it is a little bit late, i solved the PATH problem by removing every space.
;C:\Program Files\PostgreSQL\9.5\bin;C:\Program Files\PostgreSQL\9.5\lib
works for me now.
Note: my answer is about really deleting the tables and other database objects; for deleting all data in the tables, i.e. truncating all tables, Endre Both has provided a similarily well-executed (direct execution) statement a month later.
For the cases where you can’t just DROP SCHEMA public CASCADE;
, DROP OWNED BY current_user;
or something, here’s a stand-alone SQL script I wrote, which is transaction-safe (i.e. you can put it between BEGIN;
and either ROLLBACK;
to just test it out or COMMIT;
to actually do the deed) and cleans up “all” database objects… well, all those used in the database our application uses or I could sensibly add, which is:
CHECK
, UNIQUE
)VIEW
s (normal or materialised)public
or DB-internal) schemata “we” own: the script is useful when run as “not a database superuser”; a superuser can drop all schemata (the really important ones are still explicitly excluded, though)Not dropped are (some deliberate; some only because I had no example in our DB):
public
schema (e.g. for extension-provided stuff in them)This is really useful for the cases when the dump you want to restore is of a different database schema version (e.g. with Debian dbconfig-common
, Flyway or Liquibase/DB-Manul) than the database you want to restore it into.
I’ve also got a version which deletes “everything except two tables and what belongs to them” (a sequence, tested manually, sorry, I know, boring) in case someone is interested; the diff is small. Contact me or check this repo if interested.

Actually your Windows firewall is blocking the connection. You need to enter these commands into cmd.exe
from Administrator.
netsh advfirewall firewall add rule name="FTP" dir=in action=allow program=%SystemRoot%\System32\ftp.exe enable=yes protocol=tcp
netsh advfirewall firewall add rule name="FTP" dir=in action=allow program=%SystemRoot%\System32\ftp.exe enable=yes protocol=udp
In case something goes wrong then you can revert by this:
netsh advfirewall firewall delete rule name="FTP" program=%SystemRoot%\System32\ftp.exe
You can use the ToolTip class:
Creating a ToolTip for a Control
Example:
private void Form1_Load(object sender, System.EventArgs e)
{
System.Windows.Forms.ToolTip ToolTip1 = new System.Windows.Forms.ToolTip();
ToolTip1.SetToolTip(this.Button1, "Hello");
}
I do this all the time. Here's a look at an example and how you would implement it.
Change your XAML to use the Command property of the button instead of the Click event. I am using the name SaveCommand since it is easier to follow then something named Command.
<Button Command="{Binding Path=SaveCommand}" />
Your CustomClass that the Button is bound to now needs to have a property called SaveCommand of type ICommand
. It needs to point to the method on the CustomClass that you want to run when the command is executed.
public MyCustomClass
{
private ICommand _saveCommand;
public ICommand SaveCommand
{
get
{
if (_saveCommand == null)
{
_saveCommand = new RelayCommand(
param => this.SaveObject(),
param => this.CanSave()
);
}
return _saveCommand;
}
}
private bool CanSave()
{
// Verify command can be executed here
}
private void SaveObject()
{
// Save command execution logic
}
}
The above code uses a RelayCommand which accepts two parameters: the method to execute, and a true/false value of if the command can execute or not. The RelayCommand class is a separate .cs file with the code shown below. I got it from Josh Smith :)
/// <summary>
/// A command whose sole purpose is to
/// relay its functionality to other
/// objects by invoking delegates. The
/// default return value for the CanExecute
/// method is 'true'.
/// </summary>

readonly Predicate<object> _canExecute;
#endregion // Fields

{
}
/// <summary>
/// Creates a new command.
/// </summary>
/// <param name="execute">The execution logic.</param>
/// <param name="canExecute">The execution status logic.</param>
public RelayCommand(Action<object> execute, Predicate<object> canExecute)
{
if (execute == null)
throw new ArgumentNullException("execute");
_execute = execute;
_canExecute = canExecute;
}

If you want to deliver a bundle of your application jar, together with all its dependencies and some scripts to invoke the MainClass, look at the appassembler-maven-plugin.
The following configuration will generate scripts for Window and Linux to launch the application (with a generated path referencing all the dependency jars, download all dependencies (into a lib folder below target/appassembler). The assembly plugin can then be used to package the whole appassembler directory to a zip which is installed/deployed along with the jar to the repository.

In Visual Studio the default stack size is 1 MB i think, so with a recursion depth of 10,000 each stack frame can be at most ~100 bytes which should be sufficient for a DFS algorithm.
Most compilers including Visual Studio let you specify the stack size. On some (all?) linux flavours the stack size isn't part of the executable but an environment variable in the OS. You can then check the stack size with ulimit -s
and set it to a new value with for example ulimit -s 16384
.
Here's a link with default stack sizes for gcc.
DFS without recursion:
std::stack<Node> dfs;
dfs.push(start);
do {
Node top = dfs.top();
if (top is what we are looking for) {
break;
}
dfs.pop();
for (outgoing nodes from top) {
dfs.push(outgoing node);
}
} while (!dfs.empty())
Many changes you can make very easily and visually in the table editor in SQL Server Management Studio actually require SSMS to drop the table in the background and re-create it from scratch. Even simple things like reordering the columns cannot be expressed in standard SQL DDL statement - all SSMS can do is drop and recreate the table.
This operation can be a) very time consuming on a large table, or b) might even fail for various reasons (like FK constraints and stuff). Therefore, SSMS in SQL Server 2008 introduced that new option the other answers have already identified.
It might seem counter-intuitive at first to prevent such changes - and it's certainly a nuisance on a dev server. But on a production server, this option and its default value of preventing such changes becomes a potential life-saver!
In Visual Studio 2013 I struggled with this for a while and it is pretty much easy to solve just follow what the exceptions says "virtual directory not being configured as an application in IIS"

Procedure never returns a value.You have to use a output parameter in store procedure.
ALTER PROC TESTLOGIN
@UserName varchar(50),
@password varchar(50)
@retvalue int output
as
Begin
declare @return int
set @return = (Select COUNT(*)
FROM CPUser
WHERE UserName = @UserName AND Password = @password)
set @retvalue=@return
End
Then you have to add a sqlparameter from c# whose parameter direction is out. Hope this make sense.
Highlight table name in the console and press ALT+F1
A pure solution without jQuery:
function chbg(color) {
document.getElementById('b').style.backgroundColor = color;
}
<div id="a" onmouseover="chbg('red')" onmouseout="chbg('white')">This is element a</div>
<div id="b">This is element b</div>

You can use the append function to add another element to it. Only, make a series of the new element, before you append it:
test = test.append(pd.Series(200, index=[101]))
I think you can get it using subc1.text
.

Or if you want to explore it, you can use .contents

You don't need to eject, you can modify the react-scripts
config with the rescripts library
This would work then:
module.exports = config => {
const scopePluginIndex = config.resolve.plugins.findIndex(
({ constructor }) => constructor && constructor.name === "ModuleScopePlugin"
);
config.resolve.plugins.splice(scopePluginIndex, 1);
return config;
};
Get the content of the JSON file using file_get_contents()
:
$str = file_get_contents('http://example.com/example.json/');
Now decode the JSON using json_decode()
:
$json = json_decode($str, true); // decode the JSON into an associative array
You have an associative array containing all the information. To figure out how to access the values you need, you can do the following:
echo '<pre>' . print_r($json, true) . '</pre>';
This will print out the contents of the array in a nice readable format. Note that the second parameter is set to true
in order to let print_r()
know that the output should be returned (rather than just printed to screen). Then, you access the elements you want, like so:
$temperatureMin = $json['daily']['data'][0]['temperatureMin'];
$temperatureMax = $json['daily']['data'][0]['temperatureMax'];
Or loop through the array however you wish:
foreach ($json['daily']['data'] as $field => $value) {
// Use $field and $value here
}
You can use the return value of the function to prevent the form submission
<form name="myForm" onsubmit="return validateMyForm();">
and function like
<script type="text/javascript">
function validateMyForm()
{
if(check if your conditions are not satisfying)
{
alert("validation failed false");
returnToPreviousPage();
return false;
}
alert("validations passed");
return true;
}
</script>
In case of Chrome 27.0.1453.116 m if above code does not work, please set the event handler's parameter's returnValue field to false to get it to work.
Thanks Sam for sharing information.
EDIT :
Thanks to Vikram for his workaround for if validateMyForm() returns false:
<form onsubmit="event.preventDefault(); validateMyForm();">
where validateMyForm() is a function that returns false if validation fails. The key point is to use the name event. We cannot use for e.g. e.preventDefault()
jQuery is not the same as an array. If you want to append something at the end of a jQuery object, use:
$('#fruit').append(veggies);
or to append it to the end of a form value like in your example:
$('#fruit').val($('#fruit').val()+veggies);
In your case, fruitvegbasket
is a string that contains the current value of #fruit
, not an array.
jQuery (jquery.com) allows for DOM manipulation, and the specific function you called val()
returns the value
attribute of an input
element as a string. You can't push something onto a string.
I liked the approach of creating a directive to do this (good call @yurzui).
I ended up finding a Medium article Angular "let" Directive which explains this problem nicely and proposes a custom let directive which ended up working great for my use case with minimal code changes.
Here's the gist (at the time of posting) with my modifications:
import { Directive, Input, TemplateRef, ViewContainerRef } from '@angular/core'
interface LetContext <T> {
appLet: T | null
}
@Directive({
selector: '[appLet]',
})
export class LetDirective <T> {
private _context: LetContext <T> = { appLet: null }
constructor(_viewContainer: ViewContainerRef, _templateRef: TemplateRef <LetContext <T> >) {
_viewContainer.createEmbeddedView(_templateRef, this._context)
}
@Input()
set appLet(value: T) {
this._context.appLet = value
}
}
My main changes were:
appLet: T
to appLet: T | null
Not sure why the Angular team hasn't just made an official ngLet directive but whatevs.

SelectionChange is the event built into the Excel Object model for this. It should do exactly as you want, firing any time the user clicks anywhere...
I'm not sure that I understand your objections to global variables here, you would only need 1 if you use the Application.SelectionChange event. However, you wouldn't need any if you utilize the Workbook class code behind (to trap the Workbook.SelectionChange event) or the Worksheet class code behind (to trap the Worksheet.SelectionChange) event. (Unless your issue is the "global variable reset" problem in VBA, for which there is only one solution: error handling everywhere. Do not allow any unhandled errors, instead log them and/or "soft-report" an error as a message box to the user.)
You might also need to trap the Worksheet.Activate() and Worksheet.Deactivate() events (or the equivalent in the Workbook class) and/or the Workbook.Activate and Workbook.Deactivate() events so that you know when the user has switched worksheets and/or workbooks. The Window activate and deactivate events should make this approach complete. They could all call the same exact procedure, however, they all denote the same thing: the user changed the "focus", if you will.
If you don't like VBA, btw, you can do the same using VB.NET or C#.
[Edit: Dbb makes a very good point about the SelectionChange event not picking up a click when the user clicks within the currently selected cell. If you need to pick that up, then you would need to use subclassing.]
They are lists because you type them as lists in the dictionary:
bikes = {
# Bike designed for children"
"Trike": ["Trike", 20, 100],
# Bike designed for everyone"
"Kruzer": ["Kruzer", 50, 165]
}
You should use the bike-class instead:
bikes = {
# Bike designed for children"
"Trike": Bike("Trike", 20, 100),
# Bike designed for everyone"
"Kruzer": Bike("Kruzer", 50, 165)
}
This will allow you to get the cost of the bikes with bike.cost as you were trying to.
for bike in bikes.values():
profit = bike.cost * margin
print(bike.name + " : " + str(profit))
This will now print:
Kruzer : 33.0
Trike : 20.0
\usepackage{array}
in the preamble
then this:
\begin{tabular}{| >{\centering\arraybackslash}m{1in} | >{\centering\arraybackslash}m{1in} |}
note that the "m" for fixed with column is provided by the array package, and will give you vertical centering (if you don't want this just go back to "p"

In general, it's impossible to do. Here's one particularly nasty case:
struct Point2d {
int x;
int y;
};
struct Point3d {
int x;
int y;
int z;
};
void dump(Point3 *p)
{
printf("[%d %d %d]\n", p->x, p->y, p->z);
}
Point2d points[2] = { {0, 1}, {2, 3} };
Point3d *p3 = reinterpret_cast<Point3d *>(&points[0]);
dump(p3);
On many platforms, this will print out:
[0 1 2]
You're forcing the runtime system to incorrectly interpret bits of memory, but in this case it's not going to crash, because the bits all make sense. This is part of the design of the language (look at C-style polymorphism with struct inaddr
, inaddr_in
, inaddr_in6
), so you can't reliably protect against it on any platform.

You don't actually have to enumerate all the possible combinations for every possible values, because you can build it on top of previous answers.
You algorithm need to take 2 parameters:
[1, 5, 10, 25]
[1, 99]
And the goal is to compute the minimal set of coins required for this range.
The simplest way is to proceed in a bottom-up fashion:
Range Number of coins (in the minimal set)
1 5 10 25
[1,1] 1
[1,2] 2
[1,3] 3
[1,4] 4
[1,5] 5
[1,5]* 4 1 * two solutions here
[1,6] 4 1
[1,9] 4 1
[1,10] 5 1 * experience tells us it's not the most viable one :p
[1,10] 4 2 * not so viable either
[1,10] 4 1 1
[1,11] 4 1 1
[1,19] 4 1 1
[1,20] 5 1 1 * not viable (in the long run)
[1,20] 4 2 1 * not viable (in the long run)
[1,20] 4 1 2
It is somewhat easy, at each step we can proceed by adding at most one coin, we just need to know where. This boils down to the fact that the range [x,y]
is included in [x,y+1]
thus the minimal set for [x,y+1]
should include the minimal set for [x,y]
.
As you may have noticed though, sometimes there are indecisions, ie multiple sets have the same number of coins. In this case, it can only be decided later on which one should be discarded.
It should be possible to improve its running time, when noticing that adding a coin usually allows you to cover a far greater range that the one you added it for, I think.
For example, note that:
[1,5] 4*1 1*5
[1,9] 4*1 1*5
we add a nickel to cover [1,5]
but this gives us up to [1,9]
for free!
However, when dealing with outrageous input sets [2,3,5,10,25]
to cover [2,99]
, I am unsure as how to check quickly the range covered by the new set, or it would be actually more efficient.
The best solution in my opinion is add a plugin in the pom.xml, and you don't need to do anything else all the time:
<build>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
<configuration>
<jvmArguments>
-Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=9898
</jvmArguments>
</configuration>
<executions>
<execution>
<goals>
<goal>repackage</goal>
</goals>
</execution>
</executions>
</plugin>
I haven't tested on other Laravel versions but on 5.3-5.8 you reference the query parameter as if it were a member of the Request
class
.
http://example.com/path?page=2
Route::get('/path', function(Request $request){
dd($request->page);
});
//or in your controller
public function foo(Request $request){
dd($request->page);
}
//NOTE: If you are wondering where the request instance is coming from, Laravel automatically injects the request instance from the IOC container
//output
"2"
We can also pass in a default value which is returned if a parameter doesn't exist. It's much cleaner than a ternary expression that you'd normally use with the request globals
//wrong way to do it in Laravel
$page = isset($_POST['page']) ? $_POST['page'] : 1;
//do this instead
$request->get('page', 1);
//returns page 1 if there is no page
//NOTE: This behaves like $_REQUEST array. It looks in both the
//request body and the query string
$request->input('page', 1);
$page = request('page', 1);
//returns page 1 if there is no page parameter in the query string
//it is the equivalent of
$page = 1;
if(!empty($_GET['page'])
$page = $_GET['page'];
The default parameter is optional therefore one can omit it
While the input method retrieves values from entire request payload (including the query string), the query method will only retrieve values from the query string
//this is the equivalent of retrieving the parameter
//from the $_GET global array
$page = $request->query('page');
//with a default
$page = $request->query('page', 1);
$page = Request::get('page');
//with a default value
$page = Request::get('page', 1);
You can read more in the official documentation https://laravel.com/docs/5.8/requests
Probably because you forgot to implement the solution in the accepted answer. That's the code that makes trim()
work.
update
This answer only applies to older browsers. Newer browsers apparently support trim()
natively.
You probably want to start investigating the os module for forking different threads (by opening an interactive session and issuing help(os)). The relevant functions are fork and any of the exec ones. To give you an idea on how to start, put something like this in a function that performs the fork (the function needs to take a list or tuple 'args' as an argument that contains the program's name and its parameters; you may also want to define stdin, out and err for the new thread):
try:
pid = os.fork()
except OSError, e:
## some debug output
sys.exit(1)
if pid == 0:
## eventually use os.putenv(..) to set environment variables
## os.execv strips of args[0] for the arguments
os.execv(args[0], args)
As @DSM points out, you can do this more directly using the vectorised string methods:
df['Date'].str[-4:].astype(int)
Or using extract (assuming there is only one set of digits of length 4 somewhere in each string):
df['Date'].str.extract('(?P<year>\d{4})').astype(int)
An alternative slightly more flexible way, might be to use apply
(or equivalently map
) to do this:
df['Date'] = df['Date'].apply(lambda x: int(str(x)[-4:]))
# converts the last 4 characters of the string to an integer
The lambda function, is taking the input from the Date
and converting it to a year.
You could (and perhaps should) write this more verbosely as:
def convert_to_year(date_in_some_format):
date_as_string = str(date_in_some_format) # cast to string
year_as_string = date_in_some_format[-4:] # last four characters
return int(year_as_string)
df['Date'] = df['Date'].apply(convert_to_year)
Perhaps 'Year' is a better name for this column...
Try following code;
DropDownList1.Items.Add(new ListItem(txt_box1.Text));

To close all splits, I usually place the cursor in the window that shall be the on-ly visible one and then do :on
which makes the current window the on-ly visible window. Nice mnemonic to remember.
Edit: :help :on
showed me that these commands are the same:
Each of these four closes all windows except the active one.

Look at the const
and static
section of the Rust book.
You can use something as follows:
const N: i32 = 5;
or
static N: i32 = 5;
in global space.
But these are not mutable. For mutability, you could use something like:
static mut N: i32 = 5;
Then reference them like:
unsafe {
N += 1;
println!("N: {}", N);
}
As of kotlin 1.2, you could write:
(1..3).shuffled().last()
Just be aware it's big O(n), but for a small list (especially of unique values) it's alright :D
c="123".match(/\D/) == null #true
c="a12".match(/\D/) == null #false
If a string contains only digits it will return null
Adding to the above. You use the Dispatch timer if you want the tick events marshalled back to the UI thread. Otherwise I would use System.Timers.Timer.
For alphabetical order following nationalization, use Collator
.
//Get the Collator for US English and set its strength to PRIMARY
Collator usCollator = Collator.getInstance(Locale.US);
usCollator.setStrength(Collator.PRIMARY);
if( usCollator.compare("abc", "ABC") == 0 ) {
System.out.println("Strings are equivalent");
}
For a list of supported locales, see JDK 8 and JRE 8 Supported Locales.
The way I usually explain this to people is to show how it's similar to other JavaScript patterns.
First, you should know that there are two ways to declare a function (actually, there's at least five, but these are the two main culprits):
function foo() {/*code*/}
and
var foo = function() {/*code*/};
Even if this construction looks strange, you probably use it all the time when attaching events:
window.onload=function(){/*code*/};
You should notice that the second form is not much different from a regular variable declaration:
var bar = 5;
var baz = 'some string';
var foo = function() {/*code*/};
But in JavaScript, you always have the choice between using a value directly or through a variable. If bar
is 5
, then the next two statements are equivalent:
var myVal = bar * 100; // use 'bar'
var myVal = 5 * 100; // don't use 'bar'
Well, if you can use 5
on its own, why can't you use function() {\*code*\}
on its own too? In fact, you can. And that's called an anonymous function. So these two examples are equivalent as well:
var foo = function() {/*code*/}; // use 'foo'
foo();
(function(){/*code*/})(); // don't use 'foo'
The only difference you should see is in the extra brackets. That's simply because if you start a line with the keyword function
, the parser will think you are declaring a function using the very first pattern at the top of this answer and throw a syntax error exception. So wrap your entire anonymous function inside a pair of braces and the problem goes away.
In other words, the following three statements are valid:
5; // pointless and stupid
'some string'; // pointless and stupid
(function(){/*code*/})(); // wonderfully powerful
[EDIT in 2020]
The previous version of my answer recommended Douglas Crockford's form of parens-wrapping for these "immediately invoked anonymous functions". User @RayLoveless recommended in 2012 to use the version shown now. Back then, before ES6 and arrow functions, there was no obvious idiomatic difference; you simply had to prevent the statement starting with the function
keyword. In fact, there were lots of ways to do that. But using parens, these two statements were syntactically and idiomatically equivalent:
( function() { /* code */}() );
( function() { /* code */} )();
But user @zentechinc's comment below reminds me that arrow functions change all this. So now only one of these statements is correct.
( () => { /* code */ }() ); // Syntax error
( () => { /* code */ } )();
Why on earth does this matter? Actually, it's pretty easy to demonstrate. Remember an arrow function can come in two basic forms:
() => { return 5; }; // With a function body
() => { console.log(5); };
() => 5; // Or with a single expression
() => console.log(5);
Without parens wrapping this second type of arrow function, you end up with an idiomatic mess:
() => 5(); // How do you invoke a 5?
() => console.log(5)(); // console.log does not return a function!
Use immediate children selector >
:
$('#tblOne > tbody > tr')
Description: Selects all direct child elements specified by "child" of elements specified by "parent".
Sorting such a vector
or any other applicable (mutable input iterator) range of custom objects of type X
can be achieved using various methods, especially including the use of standard library algorithms like
Since most of the techniques, to obtain relative ordering of X
elements, have already been posted, I'll start by some notes on "why" and "when" to use the various approaches.
The "best" approach will depend on different factors:
X
objects a common or a rare task (will such ranges be sorted a mutiple different places in the program or by library users)?X
objects be foolproof?If sorting ranges of X
is a common task and the achieved sorting is to be expected (i.e. X
just wraps a single fundamental value) then on would probably go for overloading operator<
since it enables sorting without any fuzz (like correctly passing proper comparators) and repeatedly yields expected results.
If sorting is a common task or likely to be required in different contexts, but there are multiple criteria which can be used to sort X
objects, I'd go for Functors (overloaded operator()
functions of custom classes) or function pointers (i.e. one functor/function for lexical ordering and another one for natural ordering).
If sorting ranges of type X
is uncommon or unlikely in other contexts I tend to use lambdas instead of cluttering any namespace with more functions or types.
This is especially true if the sorting is not "clear" or "natural" in some way. You can easily get the logic behind the ordering when looking at a lambda that is applied in-place whereas operator<
is opague at first sight and you'd have to look the definition up to know what ordering logic will be applied.
Note however, that a single operator<
definition is a single point of failure whereas multiple lambas are multiple points of failure and require a more caution.
If the definition of operator<
isn't available where the sorting is done / the sort template is compiled, the compiler might be forced to make a function call when comparing objects, instead of inlining the ordering logic which might be a severe drawback (at least when link time optimization/code generation is not applied).
class X
in order to use standard library sorting algorithmsLet std::vector<X> vec_X;
and std::vector<Y> vec_Y;
T::operator<(T)
or operator<(T, T)
and use standard library templates that do not expect a comparison function.Either overload member operator<
:
struct X {
int i{};
bool operator<(X const &r) const { return i < r.i; }
};
// ...
std::sort(vec_X.begin(), vec_X.end());
or free operator<
:
struct Y {
int j{};
};
bool operator<(Y const &l, Y const &r) { return l.j < r.j; }
// ...
std::sort(vec_Y.begin(), vec_Y.end());
struct X {
int i{};
};
bool X_less(X const &l, X const &r) { return l.i < r.i; }
// ...
std::sort(vec_X.begin(), vec_X.end(), &X_less);
bool operator()(T, T)
overload for a custom type which can be passed as comparison functor.struct X {
int i{};
int j{};
};
struct less_X_i
{
bool operator()(X const &l, X const &r) const { return l.i < r.i; }
};
struct less_X_j
{
bool operator()(X const &l, X const &r) const { return l.j < r.j; }
};
// sort by i
std::sort(vec_X.begin(), vec_X.end(), less_X_i{});
// or sort by j
std::sort(vec_X.begin(), vec_X.end(), less_X_j{});
Those function object definitions can be written a little more generic using C++11 and templates:
struct less_i
{
template<class T, class U>
bool operator()(T&& l, U&& r) const { return std::forward<T>(l).i < std::forward<U>(r).i; }
};
which can be used to sort any type with member i
supporting <
.
struct X {
int i{}, j{};
};
std::sort(vec_X.begin(), vec_X.end(), [](X const &l, X const &r) { return l.i < r.i; });
Where C++14 enables a even more generic lambda expression:
std::sort(a.begin(), a.end(), [](auto && l, auto && r) { return l.i < r.i; });
which could be wrapped in a macro
#define COMPARATOR(code) [](auto && l, auto && r) -> bool { return code ; }
making ordinary comparator creation quite smooth:
// sort by i
std::sort(v.begin(), v.end(), COMPARATOR(l.i < r.i));
// sort by j
std::sort(v.begin(), v.end(), COMPARATOR(l.j < r.j));
I was getting this error in PyroCMS.
You can improve the error message in the Loader.php file that is in the code of the library.
Open the Loader.php file and find any calls to show_error
. I replaced mine with the following:
show_error(sprintf("Unable to load the requested file: \"%s\" with instance title of \"%s\"", $_ci_file, $_ci_data['_ci_vars']['options']['instance_title']));
I was then able to see which file was causing the issues for me.
Well, longs can't hold anything but integers.
One option is to use a float: float('234.89')
The other option is to truncate or round. Converting from a float to a long will truncate for you: long(float('234.89'))
>>> long(float('1.1'))
1L
>>> long(float('1.9'))
1L
>>> long(round(float('1.1')))
1L
>>> long(round(float('1.9')))

In all these scenarios outerScopeVar
is modified or assigned a value asynchronously or happening in a later time(waiting or listening for some event to occur),for which the current execution will not wait.So all these cases current execution flow results in outerScopeVar = undefined
Let's discuss each examples(I marked the portion which is called asynchronously or delayed for some events to occur):
1.
Here we register an eventlistner which will be executed upon that particular event.Here loading of image.Then the current execution continuous with next lines img.src = 'lolcat.png';
and alert(outerScopeVar);
meanwhile the event may not occur. i.e, funtion img.onload
wait for the referred image to load, asynchrously. This will happen all the folowing example- the event may differ.
2.
Here the timeout event plays the role, which will invoke the handler after the specified time. Here it is 0
, but still it registers an asynchronous event it will be added to the last position of the Event Queue
for execution, which makes the guaranteed delay.
3.
4.
Node can be consider as a king of asynchronous coding.Here the marked function is registered as a callback handler which will be executed after reading the specified file.
5.
Obvious promise (something will be done in future) is asynchronous. see What are the differences between Deferred, Promise and Future in JavaScript?

body: err ? err.message : JSON.stringify(res),
headers:{ 'Access-Control-Allow-Origin' : '*' },

Not 100%; however, it sounds like the heap is an object or set of allocated space (on RAM) that is built into the functionality of the code either Java itself or more likely functionality from ehcache itself, and the off-heap Ram is there own system as well; however, it sounds like this is one magnitude slower as it is not as organized, meaning it may not use a heap (meaning one long set of space of ram), and instead uses different address spaces likely making it slightly less efficient.
Then of course the next tier lower is hard-drive space itself.
I don't use ehcache, so you may not want to trust me, but that what is what I gathered from their documentation.
A slight variation on the above simplified approach.
var result = yyy.Distinct().Count() == yyy.Count();
First of all, make sure you have added the BOOLEAN key "View controller-based status bar appearance" to Info.plist, and set the value to "NO".
Appdelegate.swift
Insert code somewhere after "launchOptions:[UIApplicationLaunchOptionsKey: Any]?) -> Bool {"
UITabBar.appearance().barTintColor = UIColor(red: 0.145, green: 0.592, blue: 0.804, alpha: 1.00)
OR one of the default UI colors:
UITabBar.appearance().barTintColor = UIColor.white)
The selected item
UITabBarItem.appearance().setTitleTextAttributes([NSForegroundColorAttributeName: UIColor.white], for: .selected)
The inactive items
UITabBarItem.appearance().setTitleTextAttributes([NSForegroundColorAttributeName: UIColor.black], for: .normal)
If you don´t make the icons from scratch, alternating black and white versions are relatively easy to make in Photoshop.
Adobe Photoshop (almost any version will do)
Make sure your icon image has transparent background, and the icon itself is solid black (or close).
Open the image file, save it under a different file name (e.g. exampleFilename-Inverted.png)
In the "Adjustments" submenu on the "Image" menu:
Click "Invert"
You now have a negative of your original icon.
In XCode, set one of the images as "Selected Image" under the Tab Bar Properties in your storyboard, and specify the "inactive" version under "Bar Item" image.

One trick that used to be documented in a Sun manual for make
is to use a (non-existent) target '.FORCE'. You could do this by creating a file, force.mk, that contains:
.FORCE:
$(FORCE_DEPS): .FORCE
Then, assuming your existing makefile is called makefile
, you could run:
make FORCE_DEPS=release -f force.mk -f makefile release
Since .FORCE
does not exist, anything that depends on it will be out of date and rebuilt.
All this will work with any version of make
; on Linux, you have GNU Make and can therefore use the .PHONY target as discussed.
It is also worth considering why make
considers release to be up to date. This could be because you have a touch release
command in amongst the commands executed; it could be because there is a file or directory called 'release' that exists and has no dependencies and so is up to date. Then there's the actual reason...

Incorrect:
SELECT * FROM customers WHERE name LIKE '%Bob Smith%';
Instead:
select count(*)
from rearp.customers c
where c.name LIKE '%Bob smith.8%';
select count
will just query (totals)
C
will link the db.table to the names row you need this to index
LIKE
should be obvs
8
will call all references in DB 8 or less (not really needed but i like neatness)
For XSL (on really lazy days) I use:

We have cases where the input is in CDATA but the system which uses the XML doesn't take it into account. It's a sloppy fix, beware...
The function you're after is numpy.linalg.norm
. (I reckon it should be in base numpy as a property of an array -- say x.norm()
-- but oh well).
import numpy as np
x = np.array([1,2,3,4,5])
np.linalg.norm(x)
You can also feed in an optional ord
for the nth order norm you want. Say you wanted the 1-norm:
np.linalg.norm(x,ord=1)
And so on.
To answer the original question: yes, you can access the index value of a row in apply()
. It is available under the key name
and requires that you specify axis=1
(because the lambda processes the columns of a row and not the rows of a column).
Working example (pandas 0.23.4):
>>> import pandas as pd
>>> df = pd.DataFrame([[1,2,3],[4,5,6]], columns=['a','b','c'])
>>> df.set_index('a', inplace=True)
>>> df
b c
a
1 2 3
4 5 6
>>> df['index_x10'] = df.apply(lambda row: 10*row.name, axis=1)
>>> df
b c index_x10
a
1 2 3 10
4 5 6 40

I was having this problem on Ubuntu 12.04.3 LTS (well beyond EOL, I know...) and got around it with:
sudo apt-get update && sudo apt-get install ca-certificates
I implemented something of that such. But, here is what I did when the message comes in, I retrieve only the six digit code, bundle it in an intent and send it to the activity or fragment needing it and verifies the code. The example shows you the way to get the sms already. Look at the code below for illustration on how to send using LocalBrodcastManager and if your message contains more texts E.g Greetings, standardize it to help you better. E.g "Your verification code is: 84HG73" you can create a regex pattern like this ([0-9]){2}([A-Z]){2}([0-9]){2}
which means two ints, two [capital] letters and two ints. Good Luck!
After discarding all un needed info from the message
Intent intent = new Intent("AddedItem");
intent.putExtra("items", code);
LocalBroadcastManager.getInstance(getActivity()).sendBroadcast(intent);
And the Fragment/Activity receiving it
@Override
public void onResume() {
LocalBroadcastManager.getInstance(getActivity()).registerReceiver(receiver, new IntentFilter("AddedItem"));
super.onResume();
}
@Override
public void onPause() {
super.onDestroy();
LocalBroadcastManager.getInstance(getActivity()).unregisterReceiver(receiver);
}
And the code meant to handle the payload you collected
private BroadcastReceiver receiver = new BroadcastReceiver() {
@Override
public void onReceive(Context context, Intent intent) {
if (intent.getAction()) {
final String message = intent.getStringExtra("message");
//Do whatever you want with the code here
}
}
};
Does that help a little bit. I did it better by using Callbacks
Please don't try and roll your own with a TreeView/DirectoryInfo class. For one thing there are many nice features you get for free (icons/right-click/networks) by using SHBrowseForFolder. For another there are a edge cases/catches you will likely not be aware of.
You can pass boolean
by coercing it, put !!
before the variable.
let isRequired = '' || null || undefined
<input :required="!!isRequired"> // it will coerce value to respective boolean
But I would like to pull your attention for the following case where the receiving component has defined type
for props. In that case, if isRequired
has defined type to be string
then passing boolean
make it type check fails and you will get Vue warning. To fix that you may want to avoid passing that prop, so just put undefined
fallback and the prop will not sent to component
let isValue = false
<any-component
:my-prop="isValue ? 'Hey I am when the value exist' : undefined"
/>
Explanation
I have been through the same problem, and tried above solutions !!
Yes, I don't see the prop
but that actually does not fulfils what required here.
My problem -
let isValid = false
<any-component
:my-prop="isValue ? 'Hey I am when the value exist': false"
/>
In the above case, what I expected is not having my-prop
get passed to the child component - <any-conponent/>
I don't see the prop
in DOM
but In my <any-component/>
component, an error pops out of prop type check failure. As in the child component, I am expecting my-prop
to be a String
but it is boolean
.
myProp : {
type: String,
required: false,
default: ''
}
Which means that child component did receive the prop even if it is false
. Tweak here is to let the child component to take the default-value
and also skip the check. Passed undefined
works though!
<any-component
:my-prop="isValue ? 'Hey I am when the value exist' : undefined"
/>
This works and my child prop is having the default value.
All you need is a check on the post side of things.

Here is the code. Integrate it according to your need. I hope it will help.
Either you can use the accessors provided by the Web Storage API or you could write a wrapper/adapter. From your stated issue with defineGetter/defineSetter is sounds like writing a wrapper/adapter is too much work for you.
I honestly don't know what to tell you. Maybe you could reevaluate your opinion of what is a "ridiculous limitation". The Web Storage API is just what it's supposed to be, a key/value store.
I solved the problem for me by addressing also the worksheet first:
ws.rows(x & ":" & y).Select
without the reference to the worksheet (ws) I got an error.
If you want customer's details that customer had entered while ordering, then you can use the following code:
$order = new WC_Order($order_id);
$billing_address = $order->get_billing_address();
$billing_address_html = $order->get_formatted_billing_address();
// For printing or displaying on the web page
$shipping_address = $order->get_shipping_address();
$shipping_address_html = $order->get_formatted_shipping_address(); // For printing or displaying on web page
Apart from this, $customer = new WC_Customer( $order_id );
can not get you customer details.
First of all, new WC_Customer()
doesn't take any arguments.
Secondly, WC_Customer
will get customer's details only when the user is logged in and he/she is not on the admin side. Instead he/she should be on website's front-end like the 'My Account', 'Shop', 'Cart', or 'Checkout' page.
I know this is tagged as a jQuery question, but you can answer this with AngularJS, also.
in your element, add the ng-click directive and use the $event variable which is the click event... prevent its default behavior:
<a href="#" ng-click="$event.preventDefault()">
You can even pass the $event variable into a function:
<a href="#" ng-click="doSomething($event)">
in that function, you do whatever you want with the click event.
You need to ensure that any code that modifies the HTTP headers is executed before the headers are sent. This includes statements like session_start()
. The headers will be sent automatically when any HTML is output.
Your problem here is that you're sending the HTML ouput at the top of your page before you've executed any PHP at all.
Move the session_start()
to the top of your document :
<?php session_start(); ?> <html> <head> <title>PHP SDK</title> </head> <body> <?php require_once 'src/facebook.php'; // more PHP code here.
Please, see this answer: https://stackoverflow.com/a/3863869/2096619
Quoting Tamlyn:
jQuery (1.4.2) gets confused if you have any form elements named "action". You can get around this by using the DOM attribute methods or simply avoid having form elements named "action".
<form action="foo"> <button name="action" value="bar">Go</button> </form> <script type="text/javascript"> $('form').attr('action', 'baz'); //this fails silently $('form').get(0).setAttribute('action', 'baz'); //this works </script>
If you have installed SQL Server, some of its services may block the port which XAMPP needs. I solved my problem by disabling SQL Server Reporting Services and now Apache starts without any problems.
Just open the services.msc
, scroll down, and find SQL Server Reporting Services. Right click on it and click Stop.
After you follow the first response, you can run your app using
react-native run-android --variant=debug
And your app will run without need for the packager
The one below works for me every time..
This site also has a few other suggestions, but this no-nonsense, no-worry one is available in a github:gist and answers your question (pasted here for convenience):
function hideAddressBar()
{
if(!window.location.hash)
{
if(document.height < window.outerHeight)
{
document.body.style.height = (window.outerHeight + 50) + 'px';
}
setTimeout( function(){ window.scrollTo(0, 1); }, 50 );
}
}
window.addEventListener("load", function(){ if(!window.pageYOffset){ hideAddressBar(); } } );
window.addEventListener("orientationchange", hideAddressBar );
As far as I can tell, the combination of extra height added to the page (which caused problems for you) and the scrollTo() statement make the address bar disappear.
From the same site the 'simplest' solution to hiding the address bar is using the scrollTo() method:
window.addEventListener("load", function() { window.scrollTo(0, 1); });
This will hide the address bar until the user scrolls.
This site places the same method inside a timeout function (the justification is not explained, but it claims the code doesn't work well without it):
// When ready...
window.addEventListener("load",function() {
// Set a timeout...
setTimeout(function(){
// Hide the address bar!
window.scrollTo(0, 1);
}, 0);
});
This worked for me on win replace REL_PATH_TO_FILE with the relative path to the file to remove Removing sensitive data from a repository The docs say full path - but that errored for me -so I tried rel path and it worked.

$products_query = "SELECT id FROM products";
$products_result = mysqli_query($conn, $products_query);
$products_row = mysqli_fetch_array($products_result);
$ids_array = [];
do
{
array_push($ids_array, $products_row['id']);
}
while($products_row = mysqli_fetch_array($products_result));
/*

print_r($ids_array);

*/
$row_counter = count($ids_array);
for ($i=0; $i < $row_counter; $i++)
{
$current_row = $ids_array[$i];
$rand = rand(1000000 , 9999999);
mysqli_query($conn , "UPDATE products SET code='$rand' WHERE id='$current_row'");
}
"Initialized from the environment variable PYTHONPATH, plus an installation-dependent default"
Here's one that i wrote:
$error = false;
$sql= "SELECT username FROM users WHERE username = '$username'";
$checkSQL = mysqli_query($db, $checkSQL);
if(mysqli_num_rows($checkSQL) != 0) {
$error = true;
echo '<span class="error">Username taken.</span>';
}
Works like a charm!
Generally, I use null for values that I know can have a "null" state; for example
if(jane.isManager == false){
jane.employees = null
}
Otherwise, if its a variable or function that's not defined yet (and thus, is not "usable" at the moment) but is supposed to be setup later, I usually leave it undefined.
Gutch's code is close, but it'll only work right if:
The Approved Method is to do it the other way around. Open the existing document with a PdfStamper, and use the returned PdfContentByte from getOverContent() to write text (and whatever else you might need) directly to the page. No second document needed.
And you can use a ColumnText to handle layout and such for you... no need to get down and dirty with beginText(),setFontAndSize(),drawText(),drawText()...,endText().
Inspired by Martijn Pieters' response.
In case you only need to delete the header from the csv
file, you can work more efficiently if you write using the standard Python file I/O library, avoiding writing with the CSV Python library:
with open("tmob_notcleaned.csv", "rb") as infile, open("tmob_cleaned.csv", "wb") as outfile:
next(infile) # skip the headers
outfile.write(infile.read())
Personally I rarely write loops myself now when I can get away with it... I use the Jakarta commons libs:
Customer findCustomerByid(final int id){
return (Customer) CollectionUtils.find(customers, new Predicate() {
public boolean evaluate(Object arg0) {
return ((Customer) arg0).getId()==id;
}
});
}
Yay! I saved one line!
To convert a string to a number, subtract 0. To convert a number to a string, add "" (the empty string).
5 + 1 will give you 6
(5 + "") + 1 will give you "51"
("5" - 0) + 1 will give you 6
FIND_IN_SET is your friend in this case
select * from shirts where FIND_IN_SET(1,colors)
I tried the first solution and it works but the end user can easily identify that the div's are refreshing as it is fadeIn(), without fade in i tried .toggle().toggle() and it works perfect. you can try like this
$("#panel").toggle().toggle();
_x000D_
it works perfectly for me as i'm developing a messenger and need to minimize and maximize the chat box's and this does it best rather than the above code.
Given that the trendline is straight, find the slope by choosing any two points and calculating:
(A) slope = (y1-y2)/(x1-x2)
Then you need to find the offset for the line. The line is specified by the equation:
(B) y = offset + slope*x
So you need to solve for offset. Pick any point on the line, and solve for offset:
(C) offset = y - (slope*x)
Now you can plug slope and offset into the line equation (B) and have the equation that defines your line. If your line has noise you'll have to decide on an averaging algorithm, or use curve fitting of some sort.
If your line isn't straight then you'll need to look into Curve fitting, or Least Squares Fitting - non trivial, but do-able. You'll see the various types of curve fitting at the bottom of the least squares fitting webpage (exponential, polynomial, etc) if you know what kind of fit you'd like.
Also, if this is a one-off, use Excel.
Try this,
DECLARE @name NVARCHAR(MAX) SET @name='xxxxTHAMIZHMANI****'SELECT Substring(@name, 5, (len(@name)-8)) as UserNames
And the output will be like, THAMIZHMANI
some great answers here, but they do not tackle how to use super()
in the case where different classes in the hierarchy have different signatures ... especially in the case of __init__
to answer that part and to be able to effectively use super()
i'd suggest reading my answer super() and changing the signature of cooperative methods.
here's just the solution to this scenario:
- the top-level classes in your hierarchy must inherit from a custom class like
SuperObject
:- if classes can take differing arguments, always pass all arguments you received on to the super function as keyword arguments, and, always accept
**kwargs
.
class SuperObject:
def __init__(self, **kwargs):
print('SuperObject')
mro = type(self).__mro__
assert mro[-1] is object
if mro[-2] is not SuperObject:
raise TypeError(
'all top-level classes in this hierarchy must inherit from SuperObject',
'the last class in the MRO should be SuperObject',
f'mro={[cls.__name__ for cls in mro]}'
)
# super().__init__ is guaranteed to be object.__init__
init = super().__init__
init()
example usage:
class A(SuperObject):
def __init__(self, **kwargs):
print("A")
super(A, self).__init__(**kwargs)
class B(SuperObject):
def __init__(self, **kwargs):
print("B")
super(B, self).__init__(**kwargs)
class C(A):
def __init__(self, age, **kwargs):
print("C",f"age={age}")
super(C, self).__init__(age=age, **kwargs)
class D(B):
def __init__(self, name, **kwargs):
print("D", f"name={name}")
super(D, self).__init__(name=name, **kwargs)
class E(C,D):
def __init__(self, name, age, *args, **kwargs):
print( "E", f"name={name}", f"age={age}")
super(E, self).__init__(name=name, age=age, *args, **kwargs)
E(name='python', age=28)
output:
E name=python age=28
C age=28
A
D name=python
B
SuperObject
crcany will generate efficient C code for any CRC, and includes a library of over one hundred known CRC definitions.
Efficient CRC code uses tables instead of bit-wise calculations. crcany generates both byte-wise routines and word-wise routines, the latter tuned to the architecture they are generated on. Word-wise is the fastest. Byte-wise is still much faster than bit-wise, but the implementation is more easily portable over architectures.
You do not seem to have a protocol definition with a specific CRC definition that you need to match. In this case, you can pick any 16-bit CRC in the catalog, and you will get good performance.
If you have a relatively low bit error rate, e.g. single digit number of errors per packet, and you want to maximize your error detection performance, you would need to look at the packet size you are applying the CRC to, assuming that that is constant or bounded, and look at the performance of the best polynomials in Philip Koopman's extensive research. The classic CRCs, such as the CCITT/Kermit 16-bit CRC or the X.25 16-bit CRC are not the best performers.
One of the good 16-bit performers in Koopman's tables that is also in the catalog of CRCs used in practice is CRC-16/DNP. It has very good performance detecting up to 6-bit errors in a packet. Following is the code generated by crcany for that CRC definition. This code assumes a little-endian architecture for the word-wise calculation, e.g. Intel x86 and x86-64, and it assumes that uintmax_t
is 64 bits. crcany can be used to generate alternative code for big-endian and other word sizes.
crc16dnp.h:
// The _bit, _byte, and _word routines return the CRC of the len bytes at mem,
// applied to the previous CRC value, crc. If mem is NULL, then the other
// arguments are ignored, and the initial CRC, i.e. the CRC of zero bytes, is
// returned. Those routines will all return the same result, differing only in
// speed and code complexity. The _rem routine returns the CRC of the remaining
// bits in the last byte, for when the number of bits in the message is not a
// multiple of eight. The low bits bits of the low byte of val are applied to
// crc. bits must be in 0..8.

If you are running tomcat from eclipse (probably problem exists with another IDEs), it could have a different configuration- not based on files .
The solution is to edit tomcat users file, as you wrote, and then start tomcat from command prompt with
{tomcat-directory}/bin/startup
Do:
NSData *data = [yourString dataUsingEncoding:NSUTF8StringEncoding];
then feel free to proceed with NSJSONSerialization:JSONObjectWithData
.
Following the comments, official documentation, and verifications, this answer was updated regarding the removal of an alleged NULL terminator:
As documented by dataUsingEncoding::
Return Value
The result of invoking
dataUsingEncoding:allowLossyConversion:
with NO as the second argument
As documented by getCString:maxLength:encoding: and cStringUsingEncoding::
note that the data returned by
dataUsingEncoding:allowLossyConversion:
is not a strict C-string since it does not have a NULL terminator
If your controller method is for something like file handling then ResponseEntity
is very handy:
@Controller
public class SomeController {
@RequestMapping.....
public ResponseEntity handleCall() {
if (isFound()) {
return new ResponseEntity(...);
}
else {
return new ResponseEntity(404);
}
}
}
If you try set a value in datetime-local
date("Y-m-d\TH:i",strtotime('2010-12-30 23:21:46'));
//output : 2010-12-30T23:21
sudo apt-get install ia32-libs
You can use the following code snippet. readlines() reads in the whole file at once and splits it by line.
line = obj.readlines()
Improving on the answer of @Adiii - It Will Cleanup The Phone Number and Remove All Duplicates
Declare a Global Variable
// Hash Maps
Map<String, String> namePhoneMap = new HashMap<String, String>();
Then Use The Function Below
private void getPhoneNumbers() {
Cursor phones = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, null, null, null);
// Loop Through All The Numbers
while (phones.moveToNext()) {
String name = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME));
String phoneNumber = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
// Cleanup the phone number
phoneNumber = phoneNumber.replaceAll("[()\\s-]+", "");
// Enter Into Hash Map
namePhoneMap.put(phoneNumber, name);
}
// Get The Contents of Hash Map in Log
for (Map.Entry<String, String> entry : namePhoneMap.entrySet()) {
String key = entry.getKey();
Log.d(TAG, "Phone :" + key);
String value = entry.getValue();
Log.d(TAG, "Name :" + value);
}
phones.close();
}
Remember in the above example the key is phone number and value is a name so read your contents like 998xxxxx282->Mahatma Gandhi instead of Mahatma Gandhi->998xxxxx282
protected void m_GenerateSHA256_Button1_Click(objectSender, EventArgs e)

var buff= new byte[size];

return Convert.ToBase64String(buff);
}
public string GenerateSHA256Hash(string input,string salt)
{
byte[]bytes=System.Text.Encoding.UTF8.GetBytes(input+salt);
new System.Security.Cyptography.SHA256Managed();
byte[]hash=sha256hashString.ComputedHash(bytes);
return bytesArrayToHexString(hash);
}

If you want to disable this warning it is important to know that there are two related warning parameters in GCC and Clang: GCC Compiler options -wno-four-char-constants and -wno-multichar
Try to use datepicker/ timepicker instead of datetimepicker like:
replace:
$('#datetimepicker1').datetimepicker();
with:
$('#datetimepicker1').datepicker(); // or timepicker for time picker
// produce the filter set by streaming the items from list 2
// assume list2 has elements of type MyClass where getStr gets the
// string that might appear in list1
Set<String> unavailableItems = list2.stream()
.map(MyClass::getStr)
.collect(Collectors.toSet());
// stream the list and use the set to filter it
List<String> unavailable = list1.stream()
.filter(e -> unavailableItems.contains(e))
.collect(Collectors.toList());
This is because findViewById()
searches in the activity_main
layout, while the button is located in the fragment's layout fragment_main
.
Move that piece of code in the onCreateView()
method of the fragment:
//...
View rootView = inflater.inflate(R.layout.fragment_main, container, false);
Button buttonClick = (Button)rootView.findViewById(R.id.button);
buttonClick.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
onButtonClick((Button) view);
}
});
Notice that now you access it through rootView
view:
Button buttonClick = (Button)rootView.findViewById(R.id.button);
otherwise you would get again NullPointerException.

All good, but for styleNode.cssText to work in IE6 with node created by javascipt, you need to append the node to the document before you set the cssText;

Postback is essentially when a form is submitted to the same page or script (.php .asp etc) as you are currently on to proccesses the data rather than sending you to a new page.
An example could be a page on a forum (viewpage.php), where you submit a comment and it is submitted to the same page (viewpage.php) and you would then see it with the new content added.
Instead of having to create a function in the ts file you can toggle a variable from the template itself. You can then use the variable to apply a specific class to the element. Like so-
<div (click)="status=!status"
[ngClass]="status ? 'success' : 'danger'">
Some content
</div>
So when status is true the class success is applied. When it is false danger class is applied.
This will work without any additional code in the ts file.
You can use this
Color getColorFromColorCode(String code){
return Color(int.parse(code.substring(1, 7), radix: 16) + 0xFF000000);
}
Matplotlib doesn't work with pixels directly, but rather physical sizes and DPI. If you want to display a figure with a certain pixel size, you need to know the DPI of your monitor. For example this link will detect that for you.
If you have an image of 3841x7195 pixels it is unlikely that you monitor will be that large, so you won't be able to show a figure of that size (matplotlib requires the figure to fit in the screen, if you ask for a size too large it will shrink to the screen size). Let's imagine you want an 800x800 pixel image just for an example. Here's how to show an 800x800 pixel image in my monitor (my_dpi=96
):
plt.figure(figsize=(800/my_dpi, 800/my_dpi), dpi=my_dpi)
So you basically just divide the dimensions in inches by your DPI.
If you want to save a figure of a specific size, then it is a different matter. Screen DPIs are not so important anymore (unless you ask for a figure that won't fit in the screen). Using the same example of the 800x800 pixel figure, we can save it in different resolutions using the dpi
keyword of savefig
. To save it in the same resolution as the screen just use the same dpi:
plt.savefig('my_fig.png', dpi=my_dpi)
To to save it as an 8000x8000 pixel image, use a dpi 10 times larger:
plt.savefig('my_fig.png', dpi=my_dpi * 10)
Note that the setting of the DPI is not supported by all backends. Here, the PNG backend is used, but the pdf and ps backends will implement the size differently. Also, changing the DPI and sizes will also affect things like fontsize. A larger DPI will keep the same relative sizes of fonts and elements, but if you want smaller fonts for a larger figure you need to increase the physical size instead of the DPI.
Getting back to your example, if you want to save a image with 3841 x 7195 pixels, you could do the following:
plt.figure(figsize=(3.841, 7.195), dpi=100)
( your code ...)
plt.savefig('myfig.png', dpi=1000)
Note that I used the figure dpi of 100 to fit in most screens, but saved with dpi=1000
to achieve the required resolution. In my system this produces a png with 3840x7190 pixels -- it seems that the DPI saved is always 0.02 pixels/inch smaller than the selected value, which will have a (small) effect on large image sizes. Some more discussion of this here.
Use the native PHP $_SERVER['HTTP_USER_AGENT']
variable instead.
and always remember this venerable explanation of Spaces + Tabs:
It was changed between 3.1 and 3.2:
This is a terse description of the new features added to bash-3.2 since the release of bash-3.1.
Quoting the string argument to the [[ command's =~ operator now forces string matching, as with the other pattern-matching operators.
So use it without the quotes thus:
i="test"
if [[ $i =~ 200[78] ]] ; then
echo "OK"
else
echo "not OK"
fi
You need to use a regular expression, so that you can specify the global (g) flag:
var s = 'some+multi+word+string'.replace(/\+/g, ' ');
(I removed the $()
around the string, as replace
is not a jQuery method, so that won't work at all.)
same as @Moo-Juice:
const char* args[] = {"01", "02", "03", "04"};
std::vector<std::string> v(args, args + sizeof(args)/sizeof(args[0])); //get array size
An issue with the answer from Michal Foksa is that it adds the query parameters first, and then expands the path variables. If query parameter contains parenthesis, e.g. {foobar}
, this will cause an exception.
The safe way is to expand the path variables first, and then add the query parameters:
String url = "http://test.com/Services/rest/{id}/Identifier";
Map<String, String> params = new HashMap<String, String>();
params.put("id", "1234");
URI uri = UriComponentsBuilder.fromUriString(url)
.buildAndExpand(params)
.toUri();
uri = UriComponentsBuilder
.fromUri(uri)
.queryParam("name", "myName")
.build()
.toUri();
restTemplate.exchange(uri , HttpMethod.PUT, requestEntity, class_p);
Here is how to do it by either option value or index. This example is a bit crude, but it shows how to do what you want:
html:
<mat-form-field id="your-id">
<mat-select>
<mat-option [value]="1">1</mat-option>
<mat-option [value]="2">2</mat-option>
</mat-select>
</mat-form-field>
ts:
function selectOptionByOptionValue(selectFormFieldElementId, valueToFind) {
const formField = element(by.id(selectFormFieldElementId));
formField.click().then(() => {
formField.element(by.tagName('mat-select'))
.getAttribute('aria-owns').then((optionIdsString: string) => {
const optionIds = optionIdsString.split(' ');
for (let optionId of optionIds) {
const option = element(by.id(optionId));
option.getText().then((text) => {
if (text === valueToFind) {
option.click();
}
});
}
});
});
}
function selectOptionByOptionIndex(selectFormFieldElementId, index) {
const formField = element(by.id(selectFormFieldElementId));
formField.click().then(() => {
formField.element(by.tagName('mat-select'))
.getAttribute('aria-owns').then((optionIdsString: string) => {
const optionIds = optionIdsString.split(' ');
const optionId = optionIds[index];
const option = element(by.id(optionId));
option.click();
});
});
}
selectOptionByOptionValue('your-id', '1'); //selects first option
selectOptionByOptionIndex('your-id', 1); //selects second option
A real problem often exists because any variables set inside will not be exported when that batch file finishes. So its not possible to export, which caused us issues. As a result, I just set the registry to ALWAYS used delayed expansion (I don't know why it's not the default, could be speed or legacy compatibility issue.)
PostgreSQL is integrated in Server.app available through the App Store in Mac OS X v10.8 (Mountain Lion). That means that it is already configured, and you only need to launch it, and then create users and databases.
Tip: Do not start with defining $PGDATA and so on. Take file locations as is.
You would have this file: /Library/Server/PostgreSQL/Config/org.postgresql.postgres.plist
To start:
sudo serveradmin start postgres
Process started with arguments:
/Applications/Server.app/Contents/ServerRoot/usr/bin/postgres_real -D /Library/Server/PostgreSQL/Data -c listen_addresses=127.0.0.1,::1 -c log_connections=on -c log_directory=/Library/Logs/PostgreSQL -c log_filename=PostgreSQL.log -c log_line_prefix=%t -c log_lock_waits=on -c log_statement=ddl -c logging_collector=on -c unix_socket_directory=/private/var/pgsql_socket -c unix_socket_group=_postgres -c unix_socket_permissions=0770
You can sudo:
sudo -u _postgres psql template1
Or connect:
psql -h localhost -U _postgres postgres
You can find the data directory, version, running status and so forth with
sudo serveradmin fullstatus postgres
Bower has finally been deprecated. End of story.
From Mattias Petter Johansson, JavaScript developer at Spotify:
In almost all cases, it's more appropriate to use Browserify and npm over Bower. It is simply a better packaging solution for front-end apps than Bower is. At Spotify, we use npm to package entire web modules (html, css, js) and it works very well.
Bower brands itself as the package manager for the web. It would be awesome if this was true - a package manager that made my life better as a front-end developer would be awesome. The problem is that Bower offers no specialized tooling for the purpose. It offers NO tooling that I know of that npm doesn't, and especially none that is specifically useful for front-end developers. There is simply no benefit for a front-end developer to use Bower over npm.
We should stop using bower and consolidate around npm. Thankfully, that is what is happening:
With browserify or webpack, it becomes super-easy to concatenate all your modules into big minified files, which is awesome for performance, especially for mobile devices. Not so with Bower, which will require significantly more labor to get the same effect.
npm also offers you the ability to use multiple versions of modules simultaneously. If you have not done much application development, this might initially strike you as a bad thing, but once you've gone through a few bouts of Dependency hell you will realize that having the ability to have multiple versions of one module is a pretty darn great feature. Note that npm includes a very handy dedupe tool that automatically makes sure that you only use two versions of a module if you actually have to - if two modules both can use the same version of one module, they will. But if they can't, you have a very handy out.
(Note that Webpack and rollup are widely regarded to be better than Browserify as of Aug 2016.)
None of the 'overflow' solutions worked for me. I'm coding a parallax effect with JavaScript using jQuery. In Chrome and Safari on OSX the elastic/rubber-band effect was messing up my scroll numbers, since it actually scrolls past the document's height and updates the window variables with out-of-boundary numbers. What I had to do was check if the scrolled amount was larger than the actual document's height, like so:
$(window).scroll(
function() {
if ($(window).scrollTop() + $(window).height() > $(document).height()) return;
updateScroll(); // my own function to do my parallaxing stuff
}
);
command-C? This at least works for the vim launched from within Terminal.app for text selected with mouse.
Additionally if you want to know which extensions are available on your server: SELECT * FROM pg_available_extensions
This is a "Center Screen DotNet 4.5 solution", using SystemParameters instead of System.Windows.Forms or My.Compuer.Screen: Since Windows 8 has changed the screen dimension calculation, the only way it works for me looks like that (Taskbar calculation included):
Private Sub Window_Loaded(ByVal sender As System.Object, ByVal e As System.Windows.RoutedEventArgs) Handles MyBase.Loaded
Dim BarWidth As Double = SystemParameters.VirtualScreenWidth - SystemParameters.WorkArea.Width
Dim BarHeight As Double = SystemParameters.VirtualScreenHeight - SystemParameters.WorkArea.Height
Me.Left = (SystemParameters.VirtualScreenWidth - Me.ActualWidth - BarWidth) / 2
Me.Top = (SystemParameters.VirtualScreenHeight - Me.ActualHeight - BarHeight) / 2
End Sub
If you are using PHP, you can check previous url using php script rather than javascript. Here is the code:
echo $_SERVER['HTTP_REFERER'];
Hope it helps even out of relevance :)

Invoke-WebRequest
follows the RFC2617 as @briantist noted, however there are some systems (e.g. JFrog Artifactory) that allow anonymous usage if the Authorization
header is absent, but will respond with 401 Forbidden
if the header contains invalid credentials.
This can be used to trigger the 401 Forbidden
response and get -Credentials
to work.
$login = Get-Credential -Message "Enter Credentials for Artifactory"
#Basic foo:bar
$headers = @{ Authorization = "Basic Zm9vOmJhcg==" }
Invoke-WebRequest -Credential $login -Headers $headers -Uri "..."
This will send the invalid header the first time, which will be replaced with the valid credentials in the second request since -Credentials
overrides the Authorization
header.

First of all check is your important change saved or not by:
$ git status
than try
$ git reset --hard
it will reset your branch to default
but if you need just undo:
$ edit (1) $ git add frotz.c filfre.c $ mailx (2) $ git reset
(3) $ git pull git://info.example.com/ nitfol

Google will eventually block your IP when you exceed a certain amount of requests.
Since Trung Le Nguyen Nhat's fiddle isn't correct at all
(it just uses the original image in the last step)
I wrote my own general fiddle with performance comparison:
Basically it's:
img.onload = function() {
var canvas = document.createElement('canvas'),
ctx = canvas.getContext("2d"),
oc = document.createElement('canvas'),
octx = oc.getContext('2d');
canvas.width = width; // destination canvas size
canvas.height = canvas.width * img.height / img.width;
var cur = {
width: Math.floor(img.width * 0.5),
height: Math.floor(img.height * 0.5)
}
oc.width = cur.width;
oc.height = cur.height;
octx.drawImage(img, 0, 0, cur.width, cur.height);
while (cur.width * 0.5 > width) {
cur = {
width: Math.floor(cur.width * 0.5),
height: Math.floor(cur.height * 0.5)
};
octx.drawImage(oc, 0, 0, cur.width * 2, cur.height * 2, 0, 0, cur.width, cur.height);
}
ctx.drawImage(oc, 0, 0, cur.width, cur.height, 0, 0, canvas.width, canvas.height);
}

I find the attribute option to be your best bet if you don't want to use javascript or jquery.
E.g to style all table cells with the word ready, In HTML do this:
<td status*="ready">Ready</td>
Then in css:
td[status*="ready"] {
color: red;
}
Try using this code:
var datetime = 1383066000000; // anything
var date = new Date(datetime);
var options = {
year: 'numeric', month: 'numeric', day: 'numeric',
};
var result = date.toLocaleDateString('en', options); // 10/29/2013
Here's my twist on it, with a runnable example. Note this will only work in the situation where Id
is unique, and you have duplicate values in other columns.
DECLARE @SampleData AS TABLE (Id int, Duplicate varchar(20))
INSERT INTO @SampleData
SELECT 1, 'ABC' UNION ALL
SELECT 2, 'ABC' UNION ALL
SELECT 3, 'LMN' UNION ALL
SELECT 4, 'XYZ' UNION ALL
SELECT 5, 'XYZ'
DELETE FROM @SampleData WHERE Id IN (
SELECT Id FROM (
SELECT
Id
,ROW_NUMBER() OVER (PARTITION BY [Duplicate] ORDER BY Id) AS [ItemNumber]
-- Change the partition columns to include the ones that make the row distinct
FROM
@SampleData
) a WHERE ItemNumber > 1 -- Keep only the first unique item
)
SELECT * FROM @SampleData
And the results:
Id Duplicate
----------- ---------
1 ABC
3 LMN
4 XYZ
Not sure why that's what I thought of first... definitely not the simplest way to go but it works.

The answers by the other authors have already addressed the problem of factors with only one level or NAs.
Today, I stumbled upon the same error when using the rstatix::anova_test()
function but my factors were okay (more than one level, no NAs, no character vectors, ...). Instead, I could fix the error by dropping all variables in the dataframe that are not included in the model. I don't know what's the reason for this behavior but just knowing about this might also be helpful when encountering this error.
Possible solution:
var tasks = dataList
.Select(data => Task.Factory.StartNew(arg => DoThreadStuff(data), TaskContinuationOptions.LongRunning | TaskContinuationOptions.PreferFairness))
.ToArray();
var timeout = TimeSpan.FromMinutes(1);
Task.WaitAll(tasks, timeout);
Assuming dataList is the list of items and each item needs to be processed in a separate thread.
The Series class has a pandas.Series.dt
accessor object with several
useful datetime attributes, including dt.days
. Access this attribute via:
timedelta_series.dt.days
You can also get the seconds
and microseconds
attributes in the same way.
Either the parameter supplied for ZIP_CODE
is larger (in length) than ZIP_CODE
s column width or the parameter supplied for CITY
is larger (in length) than CITY
s column width.
It would be interesting to know the values supplied for the two ?
placeholders.
Here is a good starting point.
HTML:
<div class="containing-table">
<div class="centre-align">
<div class="content"></div>
</div>
</div>
CSS:
.containing-table {
display: table;
width: 100%;
height: 400px; /* for demo only */
border: 1px dotted blue;
}
.centre-align {
padding: 10px;
border: 1px dashed gray;
display: table-cell;
text-align: center;
vertical-align: middle;
}
.content {
width: 50px;
height: 50px;
background-color: red;
display: inline-block;
vertical-align: top; /* Removes the extra white space below the baseline */
}
See demo at: http://jsfiddle.net/audetwebdesign/jSVyY/
.containing-table
establishes the width and height context for .centre-align
(the table-cell).
You can apply text-align
and vertical-align
to alter .centre-align
as needed.
Note that .content
needs to use display: inline-block
if it is to be centered horizontally using the text-align property.
