arr = [str(r) for r in arr]
This basically converts all your elements in string. Hence removes the encoding. Hence the u which represents encoding gets removed Will do the work easily and efficiently

Please note Craig McDaniel's solution is clearly better.
logging.Formatter's formatTime
method looks like this:
def formatTime(self, record, datefmt=None):
ct = self.converter(record.created)
if datefmt:
s = time.strftime(datefmt, ct)
else:
t = time.strftime("%Y-%m-%d %H:%M:%S", ct)
s = "%s,%03d" % (t, record.msecs)
return s
Notice the comma in "%s,%03d"
. This can not be fixed by specifying a datefmt
because ct
is a time.struct_time
and these objects do not record milliseconds.
If we change the definition of ct
to make it a datetime
object instead of a struct_time
, then (at least with modern versions of Python) we can call ct.strftime
and then we can use %f
to format microseconds:
import logging
import datetime as dt
class MyFormatter(logging.Formatter):
converter=dt.datetime.fromtimestamp
def formatTime(self, record, datefmt=None):
ct = self.converter(record.created)
if datefmt:
s = ct.strftime(datefmt)
else:
t = ct.strftime("%Y-%m-%d %H:%M:%S")
s = "%s,%03d" % (t, record.msecs)
return s
logger = logging.getLogger(__name__)
logger.setLevel(logging.DEBUG)
console = logging.StreamHandler()
logger.addHandler(console)
formatter = MyFormatter(fmt='%(asctime)s %(message)s',datefmt='%Y-%m-%d,%H:%M:%S.%f')
console.setFormatter(formatter)
logger.debug('Jackdaws love my big sphinx of quartz.')
# 2011-06-09,07:12:36.553554 Jackdaws love my big sphinx of quartz.
Or, to get milliseconds, change the comma to a decimal point, and omit the datefmt
argument:
class MyFormatter(logging.Formatter):
converter=dt.datetime.fromtimestamp
def formatTime(self, record, datefmt=None):
ct = self.converter(record.created)
if datefmt:
s = ct.strftime(datefmt)
else:
t = ct.strftime("%Y-%m-%d %H:%M:%S")
s = "%s.%03d" % (t, record.msecs)
return s
...
formatter = MyFormatter(fmt='%(asctime)s %(message)s')
...
logger.debug('Jackdaws love my big sphinx of quartz.')
# 2011-06-09 08:14:38.343 Jackdaws love my big sphinx of quartz.
You should provide a selector to the on
function:
$(document).on('change', 'input', function() {
// Does some stuff and logs the event to the console
});
In that case, it will work as you expected. Also, it is better to specify some element instead of document.
Read this article for better understanding: http://elijahmanor.com/differences-between-jquery-bind-vs-live-vs-delegate-vs-on/
using System.Linq;
string s = string.Join(";", myDict.Select(x => x.Key + "=" + x.Value).ToArray());
(And if you're using .NET 4, or newer, then you can omit the final ToArray
call.)
The conceptual differences between NULL and "empty-string" are real and very important in database design, but often misunderstood and improperly applied - here's a short description of the two:
NULL - means that we do NOT know what the value is, it may exist, but it may not exist, we just don't know.
Empty-String - means we know what the value is and that it is nothing.
Here's a simple example: Suppose you have a table with people's names including separate columns for first_name, middle_name, and last_name. In the scenario where first_name = 'John', last_name = 'Doe', and middle_name IS NULL, it means that we do not know what the middle name is, or if it even exists. Change that scenario such that middle_name = '' (i.e. empty-string), and it now means that we know that there is no middle name.
I once heard a SQL Server instructor promote making every character type column in a database required, and then assigning a DEFAULT VALUE to each of either '' (empty-string), or 'unknown'. In stating this, the instructor demonstrated he did not have a clear understanding of the difference between NULLs and empty-strings. Admittedly, the differences can seem confusing, but for me the above example helps to clarify the difference. Also, it is important to understand the difference when writing SQL code, and properly handle for NULLs as well as empty-strings.
Maybe you are looking for something like this. If you want to select the complete line when it contains both "foo" and "baz" at the same time, this RegEx will comply that:
.*(foo)+.*(baz)+|.*(baz)+.*(foo)+.*
Found a way to run the test in Android Studio. Apparently running it using Gradle Configuration will not execute any test. Instead I use JUnit Configuration. The simple way to do so is go to Select your Test Class to run and Right Click. Then choose Run. After that you'll see 2 run options. Select the bottom one (JUnit) as per the image
(note: If you can't find 2 Run Configuration to select, you'll need to remove your earlier used Configuration (Gradle Configuration) first. That could be done by Clicking on the "Select Run/Debug Configuration" icon in the Top Toolbar.
In Windows, you can change it through the registry:
; Set the TIME_WAIT delay to 30 seconds (0x1E)
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\TCPIP\Parameters]
"TcpTimedWaitDelay"=dword:0000001E
I thought this might be useful when using bootstrap and some glypicons:
<a class="btn btn-primary"
href="<%: Url.Action("Download File", "Download",
new { id = msg.Id, distributorId = msg.DistributorId }) %>">
Download
<span class="glyphicon glyphicon-paperclip"></span>
</a>
This will show an A tag, with a link to a controller, with a nice paperclip icon on it to represent a download link, and the html output is kept clean
The problem with iframes not getting 100% height is not because they're unwieldy. The problem is that for them to get 100% height they need their parents to have 100% height. If one of the iframe's parents is not 100% tall the iframe won't be able to go beyond that parent's height.
So the best possible solution would be:
html, body, iframe { height: 100%; }
…given the iframe is directly under body. If the iframe has a parent between itself and the body, the iframe will still get the height of its parent. One must explicitly set the height of every parent to 100% as well (if that's what one wants).
Tested in:
Chrome 30
, Firefox 24
, Safari 6.0.5
, Opera 16
, IE 7, 8, 9 and 10
PS: I don't mean to be picky but the solution marked as correct doesn't work on Firefox 24
at the time of this writing, but worked on Chrome 30
. Haven't tested on other browsers though. I came across the error on Firefox
because the page I was testing had very little content... It could be it's my meager markup or the CSS
reset altering the output, but if I experienced this error I guess the accepted answer doesn't work in every situation.
Update 2021
@Zeni suggested this in 2015:
iframe { height: 100vh }
...and indeed it does the trick!
Careful with positioning as it can potentially break the effect. Test thoroughly, you might not need positioning depending of what you're trying to achieve.
You use a forward declaration when you need a complete type.
You must have a full definition of the class in order to use it.
The usual way to go about this is:
1) create a file Cat_main.h
2) move
#include <string>
class Cat
{
public:
Cat(std::string str);
// Variables
std::string name;
// Functions
void Meow();
};
to Cat_main.h
. Note that inside the header I removed using namespace std;
and qualified string with std::string
.
3) include this file in both Cat_main.cpp
and Cat.cpp
:
#include "Cat_main.h"
This problem was fixed for me by using http version of repository:
npm config set registry http://registry.npmjs.org/
Add annotation @Repository to the head of userDao Class.If userDao is a interface,add this annotation to the implements of the interface.
Instruct Gradle to download Android plugin from Maven Central repository.
You do it by pasting the following code at the beginning of the Gradle build file:
buildscript {
repositories {
mavenCentral()
}
dependencies {
classpath 'com.android.tools.build:gradle:1.1.1'
}
}
Replace version string 1.0.+
with the latest version. Released versions of Gradle plugin can be found in official Maven Repository or on MVNRepository artifact search.
In the context of spring framework purpose of ContextLoaderListener is to load the other beans in your application such as the middle-tier and data-tier components that drive the back end of the application.
$_
is the active object in the current pipeline. You've started a new pipeline with $FOLDLIST | ...
so $_
represents the objects in that array that are passed down the pipeline. You should stash the FileInfo object from the first pipeline in a variable and then reference that variable later e.g.:
write-host $NEWN.Length
$file = $_
...
Move-Item $file.Name $DPATH
Element is not supported in IE8 out of the box you have to do some work to make IE8 accept custom tags.
One advantage of using an attribute over an element is that you can apply multiple directives to the same DOM node. This is particularly handy for things like form controls where you can highlight, disable, or add labels etc. with additional attributes without having to wrap the element in a bunch of tags.
There is a built in function to compare lists:
Following is the syntax for cmp() method -
cmp(list1, list2)
#!/usr/bin/python
list1, list2 = [123, 'xyz'], [123, 'xyz']
print cmp(list1,list2)
When we run above program, it produces following result -
0
If the result is a tie, meaning that 0 is returned
Just do:
document.body.innerHTML = document.body.innerHTML + '<img src="../images/loaded.gif" alt="" onload="alert(\'test\');this.parentNode.removeChild(this);" />';
You can do it with plain JavaScript:
alert('123-4-'.substr(0, 4)); // outputs "123-"
This returns the first four characters of your string (adjust 4
to suit your needs).
Ditto on the getApplicationContext thing.
The documents on the android site says to use it, but it doesn't work...grrrrr :-P
Just do:
dialog = new Dialog(this);
"this" is usually your Activity from which you start the dialog.
If by application id
, you're referring to package name
, you can use the method Context::getPackageName

Adding the following line in the head tag fixed my issue.
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">

public void setAge(int age) {
this.age = age;
}
@Override
public int compareTo(Object o) {
Person other = (Person)o;
if (this == other)
return 0;
if (this.age < other.age) return 1;
else if (this.age == other.age) return 0;
else return -1;
}
public static void main(String[] args) {
Person[] arr = new Person[4];
arr[0] = new Person(50);
arr[1] = new Person(20);
arr[2] = new Person(10);
arr[3] = new Person(90);
Arrays.sort(arr);
for (int i=0; i < arr.length; i++ ) {
System.out.println(arr[i].age);
}
}
}
Here is one way of doing it.
I have the same problem.
And got the solution turning on the ASP Net from Turn Windows feature on or off
menu.
The line (or lines) between the lines beginning <<<<<<<
and ======
here:
<<<<<<< HEAD:file.txt
Hello world
=======
... is what you already had locally - you can tell because HEAD
points to your current branch or commit. The line (or lines) between the lines beginning =======
and >>>>>>>
:
=======
Goodbye
>>>>>>> 77976da35a11db4580b80ae27e8d65caf5208086:file.txt
... is what was introduced by the other (pulled) commit, in this case 77976da35a11
. That is the object name (or "hash", "SHA1sum", etc.) of the commit that was merged into HEAD
. All objects in git, whether they're commits (version), blobs (files), trees (directories) or tags have such an object name, which identifies them uniquely based on their content.
If you have no idea which Package you need to import:

I am linking to what essentially is the same discussion where Peter Lawrey is providing a good answer. Why I get a negative elapsed time using System.nanoTime()?
Many people mentioned that in Java System.nanoTime() could return negative time. I for apologize for repeating what other people already said.
It'd be cool if System.nanoTime() returned coreID where it executed.
In the head section of your html document:
<link rel="stylesheet" type="text/css" href="/path/to/ABCD.css">
Your css file should be css only and not contain any markup.
To get all indices that matches 'Smith'
>>> df[df['LastName'] == 'Smith'].index
Int64Index([1], dtype='int64')
or as a numpy array
>>> df[df['LastName'] == 'Smith'].index.to_numpy() # .values on older versions
array([1])
or if there is only one and you want the integer, you can subset
>>> df[df['LastName'] == 'Smith'].index[0]
1
You could use the same boolean expressions with .loc
, but it is not needed unless you also want to select a certain column, which is redundant when you only want the row number/index.
$update = \DB::table('student') ->where('id', $data['id']) ->limit(1) ->update( [ 'name' => $data['name'], 'address' => $data['address'], 'email' => $data['email'], 'contactno' => $data['contactno'] ]);
when i run
from c in Customers
where c.CustomerID == 1
where c.CustomerID == 2
where c.CustomerID == 3
select c
and
from c in Customers
where c.CustomerID == 1 &&
c.CustomerID == 2 &&
c.CustomerID == 3
select c customer table in linqpad
against my Customer table it output the same sql query
-- Region Parameters
DECLARE @p0 Int = 1
DECLARE @p1 Int = 2
DECLARE @p2 Int = 3
-- EndRegion
SELECT [t0].[CustomerID], [t0].[CustomerName]
FROM [Customers] AS [t0]
WHERE ([t0].[CustomerID] = @p0) AND ([t0].[CustomerID] = @p1) AND ([t0].[CustomerID] = @p2)
so in translation to sql there is no difference and you already have seen in other answers how they will be converted to lambda expressions
The dll is missing in the published (deployed environment). That is the reason why it is working in the local i.e. Visual Studio but not in the Azure Website Environment.
Just do Copy Local = true in the properties for the assembly(System.Web.Http.WebHost) and then do a redeploy, it should work fine.
What I understand is you want same connection string with different Metadata in it. So you can use a connectionstring as given below and replace "" part. I have used your given connectionString in same sequence.
connectionString="<METADATA>provider=System.Data.SqlClient;provider connection string="Data Source=SomeServer;Initial Catalog=SomeCatalog;Persist Security Info=True;User ID=Entity;Password=SomePassword;MultipleActiveResultSets=True""
For first connectionString replace <METADATA>
with "metadata=res://*/ModEntity.csdl|res://*/ModEntity.ssdl|res://*/ModEntity.msl;"
For second connectionString replace <METADATA>
with "metadata=res://*/Entity.csdl|res://*/Entity.ssdl|res://*/Entity.msl;"
For third connectionString replace <METADATA>
with "metadata=res://*/Entity.csdl|res://*/Entity.ssdl|res://*/Entity.msl|res://*/ModEntity.csdl|res://*/ModEntity.ssdl|res://*/ModEntity.msl;"
Happy coding!
If you have a list with 53 items, the last one is thelist[52]
because indexing starts at 0.
IndexError
IndexError
The IndexError
is raised when attempting to retrieve an index from a sequence (e.g. list
, tuple
), and the index isn’t found in the sequence. The Python documentation defines when this exception is raised:
Raised when a sequence subscript is out of range. (Source)
Here’s an example that raises the IndexError
:
test = list(range(53))
test[53]
---------------------------------------------------------------------------
IndexError Traceback (most recent call last)
<ipython-input-6-7879607f7f36> in <module>
1 test = list(range(53))
----> 2 test[53]
IndexError: list index out of range
The error message line for an IndexError
doesn’t provide great information. See that there is a sequence reference that is out of range and what the type of the sequence is, a list
in this case. That information, combined with the rest of the traceback, is usually enough to help quickly identify how to fix the issue.
Memcached is a newer API, it also provides memcached as a session provider which could be great if you have a farm of server.
After the version is still really low 0.2 but I have used both and I didn't encounter major problem, so I would go to memcached since it's new.
cPickle
comes with the standard library… in python 2.x. You are on python 3.x, so if you want cPickle
, you can do this:
>>> import _pickle as cPickle
However, in 3.x, it's easier just to use pickle
.
No need to install anything. If something requires cPickle
in python 3.x, then that's probably a bug.
I have an idea, which can work and it most likely to be very fast. You can sub-sample an image to say 80x60 resolution or comparable, and convert it to grey scale (after subsampling it will be faster). Process both images you want to compare. Then run normalised sum of squared differences between two images (the query image and each from the db), or even better Normalised Cross Correlation, which gives response closer to 1, if both images are similar. Then if images are similar you can proceed to more sophisticated techniques to verify that it is the same images. Obviously this algorithm is linear in terms of number of images in your database so even though it is going to be very fast up to 10000 images per second on the modern hardware. If you need invariance to rotation, then a dominant gradient can be computed for this small image, and then the whole coordinate system can be rotated to canonical orientation, this though, will be slower. And no, there is no invariance to scale here.
If you want something more general or using big databases (million of images), then you need to look into image retrieval theory (loads of papers appeared in the last 5 years). There are some pointers in other answers. But It might be overkill, and the suggest histogram approach will do the job. Though I would think combination of many different fast approaches will be even better.
Use this approach to sum the list of BigDecimal:
List<BigDecimal> values = ... // List of BigDecimal objects
BigDecimal sum = values.stream().reduce((x, y) -> x.add(y)).get();
This approach maps each BigDecimal as a BigDecimal only and reduces them by summing them, which is then returned using the get()
method.
Here's another simple way to do the same summing:
List<BigDecimal> values = ... // List of BigDecimal objects
BigDecimal sum = values.stream().reduce(BigDecimal::add).get();
Update
If I were to write the class and lambda expression in the edited question, I would have written it as follows:
import java.math.BigDecimal;
import java.util.LinkedList;
public class Demo
{
public static void main(String[] args)
{
LinkedList<Invoice> invoices = new LinkedList<>();
invoices.add(new Invoice("C1", "I-001", BigDecimal.valueOf(.1), BigDecimal.valueOf(10)));
invoices.add(new Invoice("C2", "I-002", BigDecimal.valueOf(.7), BigDecimal.valueOf(13)));
invoices.add(new Invoice("C3", "I-003", BigDecimal.valueOf(2.3), BigDecimal.valueOf(8)));
invoices.add(new Invoice("C4", "I-004", BigDecimal.valueOf(1.2), BigDecimal.valueOf(7)));
// Java 8 approach, using Method Reference for mapping purposes.
invoices.stream().map(Invoice::total).forEach(System.out::println);
System.out.println("Sum = " + invoices.stream().map(Invoice::total).reduce((x, y) -> x.add(y)).get());
}
// This is just my style of writing classes. Yours can differ.
static class Invoice
{
private String company;
private String number;
private BigDecimal unitPrice;
private BigDecimal quantity;
public Invoice()
{
unitPrice = quantity = BigDecimal.ZERO;
}
public Invoice(String company, String number, BigDecimal unitPrice, BigDecimal quantity)
{
setCompany(company);
setNumber(number);
setUnitPrice(unitPrice);
setQuantity(quantity);
}
public BigDecimal total()
{
return unitPrice.multiply(quantity);
}
public String getCompany()
{
return company;
}
public void setCompany(String company)
{
this.company = company;
}
public String getNumber()
{
return number;
}
public void setNumber(String number)
{
this.number = number;
}
public BigDecimal getUnitPrice()
{
return unitPrice;
}
public void setUnitPrice(BigDecimal unitPrice)
{
this.unitPrice = unitPrice;
}
public BigDecimal getQuantity()
{
return quantity;
}
public void setQuantity(BigDecimal quantity)
{
this.quantity = quantity;
}
}
}
Yes, here is the process:
# Navigate to a directory and initiate a local repository
git init
# Add remote repository to be tracked for changes:
git remote add origin https://github.com/username/repository_name.git
# Track all changes made on above remote repository
# This will show files on remote repository not available on local repository
git fetch
# Add file present in staging area for checkout
git check origin/master -m /path/to/file
# NOTE: /path/to/file is a relative path from repository_name
git add /path/to/file
# Verify track of file(s) being committed to local repository
git status
# Commit to local repository
git commit -m "commit message"
# You may perform a final check of the staging area again with git status
If you are still using .NET 2.0, then [IO.Path]::Combine
won't have the params string[]
overload which you need to join more than two parts, and you'll see the error Cannot find an overload for "Combine" and the argument count: "3".
Slightly less elegant, but a pure PowerShell solution is to manually aggregate path parts:
Join-Path C: (Join-Path "Program Files" "Microsoft Office")
or
Join-Path (Join-Path C: "Program Files") "Microsoft Office"
If you know some unix you could try the following:
Notes: $ means the command prompt
Say you have a file my_data.txt with content as such:
$ cat my_data.txt
This is a data file
with all of my data in it.
Then using the os
module you can use the usual sed
commands
import os
# Identifiers used are:
my_data_file = "my_data.txt"
command = "sed -i 's/all/none/' my_data.txt"
# Execute the command
os.system(command)
If you aren't aware of sed, check it out, it is extremely useful.
The simplest way is to use str directly on column names, there is no need for pd.Series
df.loc[:,df.columns.str.startswith("foo")]
Like this:
List<String> list = new ArrayList<String>();
String[] a = list.toArray(new String[0]);
Before Java6 it was recommended to write:
String[] a = list.toArray(new String[list.size()]);
because the internal implementation would realloc a properly sized array anyway so you were better doing it upfront. Since Java6 the empty array is preferred, see .toArray(new MyClass[0]) or .toArray(new MyClass[myList.size()])?
If your list is not properly typed you need to do a cast before calling toArray. Like this:
List l = new ArrayList<String>();
String[] a = ((List<String>)l).toArray(new String[l.size()]);
This is a JQuery-free version of the answer provided by raphadko and noun.
1) Create your recaptcha fields normally with this:
<div class="g-recaptcha"></div>
2) Load the script with this:
<script src="https://www.google.com/recaptcha/api.js?onload=CaptchaCallback&render=explicit" async defer></script>
3) Now call this to iterate over the fields and create the recaptchas:
var CaptchaCallback = function() {
var captchas = document.getElementsByClassName("g-recaptcha");
for(var i = 0; i < captchas.length; i++) {
grecaptcha.render(captchas[i], {'sitekey' : 'YOUR_KEY_HERE'});
}
};
If you have installed, for example, php 5.4 it could be switched in the following way to php 5.5:
$ php --version
PHP 5.4.32 (cli) (built: Aug 26 2014 15:14:01)
Copyright (c) 1997-2014 The PHP Group

$ brew unlink php54
$ brew switch php55 5.5.16
$ php --version

Clone the repository as normal:
git clone git://github.com/rspec/rspec-tmbundle.git RSpec.tmbundle
Then checkout the tag you want like so:
git checkout tags/1.1.4
This will checkout out the tag in a 'detached HEAD' state. In this state, "you can look around, make experimental changes and commit them, and [discard those commits] without impacting any branches by performing another checkout".
To retain any changes made, move them to a new branch:
git checkout -b 1.1.4-jspooner
You can get back to the master branch by using:
git checkout master
Note, as was mentioned in the first revision of this answer, there is another way to checkout a tag:
git checkout 1.1.4
But as was mentioned in a comment, if you have a branch by that same name, this will result in git warning you that the refname is ambiguous and checking out the branch by default:
warning: refname 'test' is ambiguous.
Switched to branch '1.1.4'
The shorthand can be safely used if the repository does not share names between branches and tags.
I know this question is too old, but still, I think this approach would be cleaner:
cat = $.URLDecode(cat);
$('#cbCategory option:contains("' + cat + '")').prop('selected', true);
In this case you wont need to go over the entire options with each()
.
Although by that time prop()
didn't exist so for older versions of jQuery use attr()
.
UPDATE
You have to be certain when using contains
because you can find multiple options, in case of the string inside cat
matches a substring of a different option than the one you intend to match.
Then you should use:
cat = $.URLDecode(cat);
$('#cbCategory option')
.filter(function(index) { return $(this).text() === cat; })
.prop('selected', true);

You should not map score to player. You should map player (or his name) to score:
Map<Player, Integer> player2score = new HashMap<Player, Integer>();
Then add players to map: int score = .... Player player = new Player(); player.setName("John"); // etc. player2score.put(player, score);
In this case the task is trivial:
int score = player2score.get(player);
Firstly enter cmd
.
Then write:
sc delete MySQL
After that restart your computer. When restarting your computer and opening your xampp
, you can see cross symbol on the MySQL
. Click the cross symbol and click the start. That's all.
Use CHAR_LENGTH() instead-of LENGTH() as suggested in: MySQL - length() vs char_length()
SELECT name, CHAR_LENGTH(name) AS mlen FROM mytable ORDER BY mlen DESC LIMIT 1
The other answers give you platform-specific responses, but a generic one is this:
When you install global module with npm install -g something
, npm looks up a config variable prefix
to know where to install the module.
You can get that value by running npm config get prefix
To display all the global modules available in that folder use npm ls -g --depth 0
(depth 0
to not display their dependencies).
If you want to change the global modules path, use npm config edit
and put prefix = /my/npm/global/modules/prefix
in the file or use npm config set prefix /my/npm/global/modules/prefix
.
When you use some tools like nodist, they change the platform-default installation path of global npm modules.
well looking for a simpler variation I found this:
it's truly smart, and I guess you might want to add other browsers variations too although it worked for me both on Chrome and Firefox.

Bootstrap 4 includes flexbox, so the method of vertical centering is much easier and doesn't require extra CSS.
Just use the d-flex
and align-items-center
utility classes..
<div class="jumbotron d-flex align-items-center">
<div class="container">
content
</div>
</div>
http://www.codeply.com/go/ui6ABmMTLv
Important: Vertical centering is relative to height. The parent container of the items you're attempting to center must have a defined height. If you want the height of the page use vh-100
or min-vh-100
on the parent! For example:
<div class="jumbotron d-flex align-items-center min-vh-100">
<div class="container text-center">
I am centered vertically
</div>
</div>
This is nice to know, however, as for "always check the standard libraries first" I'd never have stumbled upon the trick of Arrays.toString( myarray )
--since I was concentrating on the type of myarray to see how to do this. I didn't want to have to iterate through the thing: I wanted an easy call to make it come out similar to what I see in the Eclipse debugger and myarray.toString() just wasn't doing it.
import java.util.Arrays;
.
.
.
System.out.println( Arrays.toString( myarray ) );
I was facing this issue and fixed by putting a check in form attribute. This issue can happen when the FormGroup is not initialized.
<form [formGroup]="loginForm" *ngIf="loginForm">
OR
<form [formGroup]="loginForm" *ngIf="this.loginForm">
This will not render the form until it is initialized.
You can use the below mentioned solution
var idleTime;
$(document).ready(function () {
reloadPage();
$('html').bind('mousemove click mouseup mousedown keydown keypress keyup submit change mouseenter scroll resize dblclick', function () {
clearTimeout(idleTime);
reloadPage();
});
});
function reloadPage() {
clearTimeout(idleTime);
idleTime = setTimeout(function () {
location.reload();
}, 3000);
}
For angular6+

const id = a.payload.doc.id;
return { id, ...data };
});
})
);
To answer your second query re. how encoding works, Joel Spolsky wrote a great introductory article on this. Strongly recommended.
May be the best way to utilize "download" button is to use JavaScript players, such as Videojs (http://docs.videojs.com/) or MediaElement.js (http://www.mediaelementjs.com/)
They do not have download button by default as a rule and moreover allow you to customize visible control buttons of the player.

Before you can add files in an unversioned directory, you have to add the directory itself to the versioning:
svn add directory_name
will add the directory directory_name
and all sub-directories: http://svnbook.red-bean.com/en/1.8/svn.ref.svn.c.add.html

1) Change the extension to properties (ex. mybundle.properties.)
2) Put your file into a jar and add it to your classpath.
3) Access the properties using this code:
ResourceBundle rb = ResourceBundle.getBundle("mybundle");
String propertyValue = rb.getString("key");
Late to the party, MY two cents are given below after some research. During logout, make sure following things are happening...
Clear the client storage/session
Update the user table last login date-time and logout date-time whenever login or logout happens respectively. So login date time always should be greater than logout (Or keep logout date null if the current status is login and not yet logged out)
This is way far simple than keeping additional table of blacklist and purging regularly. Multiple device support requires additional table to keep loggedIn, logout dates with some additional details like OS-or client details.
Uncomment this line (in /conf/logging.properties
)

Few steps to add Access-Control-Allow-Origin
header to localhost or *.
Step 1: Create Cors middleware :
php artisan make:middleware Cors
Step 2: Set header in Cors middleware like this
public function handle($request, Closure $next)
{
$response = $next($request);
$response->headers->set('Access-Control-Allow-Origin' , '*');
$response->headers->set('Access-Control-Allow-Methods', 'POST, GET, OPTIONS, PUT, DELETE');
$response->headers->set('Access-Control-Allow-Headers', 'Content-Type, Accept, Authorization, X-Requested-With, Application');
return $response;
}
Step 3: We need to add Cors class in app/Http/Kernel.php
protected $middleware = [
....
\App\Http\Middleware\Cors::class,
];
Here no needed to check any middleware
because we add Cors class in $middleware
in app/Http/Kernel.php
I can't help the way it's stored, but at least formatting works correctly:
'%.1f' % round(n, 1) # Gives you '5.6'
Newer versions: (from 8.4 - mentioned in release notes)
TABLE mytablename;
Longer but works on all versions:
SELECT * FROM mytablename;
You may wish to use \x
first if it's a wide table, for readability.
For long data:
SELECT * FROM mytable LIMIT 10;
or similar.
For wide data (big rows), in the psql
command line client, it's useful to use \x
to show the rows in key/value form instead of tabulated, e.g.
\x
SELECT * FROM mytable LIMIT 10;
Note that in all cases the semicolon at the end is important.

Assuming you want an actual SQL Server MERGE
statement:
MERGE INTO dbo.energydata WITH (HOLDLOCK) AS target
USING dbo.temp_energydata AS source
ON target.webmeterID = source.webmeterID
AND target.DateTime = source.DateTime
WHEN MATCHED THEN
UPDATE SET target.kWh = source.kWh
WHEN NOT MATCHED BY TARGET THEN
INSERT (webmeterID, DateTime, kWh)
VALUES (source.webmeterID, source.DateTime, source.kWh);
If you also want to delete records in the target that aren't in the source:
MERGE INTO dbo.energydata WITH (HOLDLOCK) AS target
USING dbo.temp_energydata AS source
ON target.webmeterID = source.webmeterID
AND target.DateTime = source.DateTime
WHEN MATCHED THEN
UPDATE SET target.kWh = source.kWh
WHEN NOT MATCHED BY TARGET THEN
INSERT (webmeterID, DateTime, kWh)
VALUES (source.webmeterID, source.DateTime, source.kWh)
WHEN NOT MATCHED BY SOURCE THEN
DELETE;
Because this has become a bit more popular, I feel like I should expand this answer a bit with some caveats to be aware of.
First, there are several blogs which report concurrency issues with the MERGE
statement in older versions of SQL Server. I do not know if this issue has ever been addressed in later editions. Either way, this can largely be worked around by specifying the HOLDLOCK
or SERIALIZABLE
lock hint:
MERGE INTO dbo.energydata WITH (HOLDLOCK) AS target
[...]
You can also accomplish the same thing with more restrictive transaction isolation levels.
There are several other known issues with MERGE
. (Note that since Microsoft nuked Connect and didn't link issues in the old system to issues in the new system, these older issues are hard to track down. Thanks, Microsoft!) From what I can tell, most of them are not common problems or can be worked around with the same locking hints as above, but I haven't tested them.
As it is, even though I've never had any problems with the MERGE
statement myself, I always use the WITH (HOLDLOCK)
hint now, and I prefer to use the statement only in the most straightforward of cases.
I have done something like this to keep it simple:
edit_text.filters = arrayOf(object : InputFilter {
override fun filter(
source: CharSequence?,
start: Int,
end: Int,
dest: Spanned?,
dstart: Int,
dend: Int
): CharSequence? {
return source?.subSequence(start, end)
?.replace(Regex("[^A-Za-z0-9 ]"), "")
}
})
This way we are replacing all the unwanted characters in the new part of the source string with an empty string.
The edit_text
variable is the EditText
object we are referring to.
The code is written in kotlin

session.abandon() will not remove the sessionID cookie from the browser. Therefore any new requests after this will take the same session ID. Hence, use Response.Cookies.Add(new HttpCookie("ASP.NET_SessionId", "")); after session.abandon().
As mentioned above several times, it's not possible to catch a StackOverflowException that was raised by the System due to corrupted process-state. But there's a way to notice the exception as an event:
http://msdn.microsoft.com/en-us/library/system.appdomain.unhandledexception.aspxStarting with the .NET Framework version 4, this event is not raised for exceptions that corrupt the state of the process, such as stack overflows or access violations, unless the event handler is security-critical and has the HandleProcessCorruptedStateExceptionsAttribute attribute.
Nevertheless your application will terminate after exiting the event-function (a VERY dirty workaround, was to restart the app within this event haha, havn't done so and never will do). But it's good enough for logging!
In the .NET Framework versions 1.0 and 1.1, an unhandled exception that occurs in a thread other than the main application thread is caught by the runtime and therefore does not cause the application to terminate. Thus, it is possible for the UnhandledException event to be raised without the application terminating. Starting with the .NET Framework version 2.0, this backstop for unhandled exceptions in child threads was removed, because the cumulative effect of such silent failures included performance degradation, corrupted data, and lockups, all of which were difficult to debug. For more information, including a list of cases in which the runtime does not terminate, see Exceptions in Managed Threads.
Another method to disable link
element.removeAttribute('href');
anchor tag without href would react as disabled/plain text
<a> w/o href </a>
instead of <a href="#"> with href </a>
see jsFiddel
hope this is heplful.
The reason why has to do with the type system. C/C++ doesn't really support strings as a type. It does support the idea of a constant char array but it doesn't really fully understand the notion of a string.
In order to generate the code for a switch statement the compiler must understand what it means for two values to be equal. For items like ints and enums, this is a trivial bit comparison. But how should the compiler compare 2 string values? Case sensitive, insensitive, culture aware, etc ... Without a full awareness of a string this cannot be accurately answered.
Additionally, C/C++ switch statements are typically generated as branch tables. It's not nearly as easy to generate a branch table for a string style switch.
I always looked at scripting languages as a means to communicate with some sort of application or program. In contrast, a language which is compiled actually creates the program itself.
Now keep in mind that a scripting language usually adds on to or modifies the program that was initially created with a language that was compiled. Thus, it can certainly be part of the larger picture but the initial binaries are first created with a language that is compiled.
So I could create a scripting language which lets users perform various actions or customize my program. My program would interpret the scripted code and in turn call some kind of function. This is just a basic example. It just gives you a way to dynamically call routines within the program.
My program would have to parse the scripted code (you could refer to these as commands) and execute whatever action was intended in real time.
I see this question was already answered several times but I thought I would add my way of looking at things into the mix. Granted, some folks may disagree with this answer but this way of thinking has always helped me.
Because the SCHEDULER_ADMIN role is a powerful role allowing a grantee to execute code as any user, you should consider granting individual Scheduler system privileges instead. Object and system privileges are granted using regular SQL grant syntax. An example is if the database administrator issues the following statement:
GRANT CREATE JOB TO scott;
After this statement is executed, scott can create jobs, schedules, or programs in his schema.

As a slight improvement over the other answers, you can do the mkdir
and chmod
as a single operation using mkdir
's -m
switch.
$ mkdir -m 700 ${HOME}/.ssh
From a Linux system
$ mkdir --help
Usage: mkdir [OPTION]... DIRECTORY...
Create the DIRECTORY(ies), if they do not already exist.
Mandatory arguments to long options are mandatory for short options too.
-m, --mode=MODE set file mode (as in chmod), not a=rwx - umask
...
...
If you have a String object you want to tokenize, favor using String's split method over a StringTokenizer. If you're parsing text data from a source outside your program, like from a file, or from the user, that's where a Scanner comes in handy.
You can also likely get around this issue by requiring 'thread' in your application as such:
require 'thread'

ARIA stands for Accessible Rich Internet Applications.
WAI-ARIA is an incredibly powerful technology that allows developers to easily describe the purpose, state and other functionality of visually rich user interfaces - in a way that can be understood by Assistive Technology. WAI-ARIA has finally been integrated into the current working draft of the HTML 5 specification.
And if you are wondering what WAI-ARIA is, its the same thing.
Please note the terms WAI-ARIA and ARIA refer to the same thing. However, it is more correct to use WAI-ARIA to acknowledge its origins in WAI.
WAI = Web Accessibility Initiative
From the looks of it, ARIA is used for assistive technologies and mostly screen reading.

Shouldn't you be providing the credentials for your site, instead of passing the DefaultCredentials?
Something like request.Credentials = new NetworkCredential("UserName", "PassWord");
Also, remove request.UseDefaultCredentials = true; request.PreAuthenticate = true;
var somefancyvariable = "fancy";
Object.keys({somefancyvariable})[0];
This isn't able to be made into a function as it returns the name of the function's variable.
// THIS DOESN'T WORK
function getVarName(v) {
return Object.keys({v})[0];
}
// Returns "v"
Edit: Thanks to @Madeo for pointing out how to make this into a function.
function debugVar(varObj) {
var varName = Object.keys(varObj)[0];
console.log("Var \"" + varName + "\" has a value of \"" + varObj[varName] + "\"");
}
You will need call the function with a single element array containing the variable. debugVar({somefancyvariable});
Edit: Object.keys
can be referenced as just keys
in every browser I tested it in but according to the comments it doesn't work everywhere.
I would change your binding to be:
<button type="button" value="click me" onclick="check_me" />
I would then change your check_me()
function declaration to be:
function check_me() {
//event.preventDefault();
var hello = document.myForm.username.value;
var err = '';
if(hello == '' || hello == null) {
err = 'User name required';
}
if(err != '') {
alert(err);
$('username').focus();
event.preventDefault();
} else {
return true; }
}
You need ReDim
:
m = 5
n = 8
Dim my_array()
ReDim my_array(1 To m, 1 To n)
For i = 1 To m
For j = 1 To n
my_array(i, j) = i * j
Next
Next
For i = 1 To m
For j = 1 To n
Cells(i, j) = my_array(i, j)
Next
Next
As others have pointed out, your actual problem would be better solved with ranges. You could try something like this:
Dim r1 As Range
Dim r2 As Range
Dim ws1 As Worksheet
Dim ws2 As Worksheet
Set ws1 = Worksheets("Sheet1")
Set ws2 = Worksheets("Sheet2")
totalRow = ws1.Range("A1").End(xlDown).Row
totalCol = ws1.Range("A1").End(xlToRight).Column
Set r1 = ws1.Range(ws1.Cells(1, 1), ws1.Cells(totalRow, totalCol))
Set r2 = ws2.Range(ws2.Cells(1, 1), ws2.Cells(totalRow, totalCol))
r2.Value = r1.Value
In the VBA Editor's Tools menu, click References... scroll down to "Microsoft Shell Controls And Automation" and choose it.

The simplest way is to replace the canvas element and then call new Chart() again:
function reloadMyChart() {
$('myChart').replaceWith('<canvas id="myChart"></canvas>');
new Chart(document.getElementById("myChart"), {
data: yourChartData,
type: yourChartType,
options: yourChartOptions
});
}
Of course, you must replace yourChartData, yourChartType and yourChartOptions with the correct values required to initialize Chart.js. See Chart.js Docs.
You can call reloadMyChart function on a button click or any other event you need. Probably you'll add parameters to this function and use these to make a REST call to dynamically update your chart, like this:
function reloadMyChart(param1, param2) {
$('myChart').replaceWith('<canvas id="myChart"></canvas>');
$.get("restUrl?param1=" + param1 + "¶m2=" + param2 + ",
function(data) {
// call new Chart() here and use returned data
}
);
Hope it helps! =)
This seems like an XML problem. Open the XML document containing your Web-View. Delete the padding code at the top.
Then in the layout , add
android:layout_width="fill_parent"
android:layout_height="fill_parent"
In the Web-View, add
android:layout_width="fill_parent"
android:layout_height="fill_parent"
This makes the Web-View fit the device screen.
in my case it was just an intermittent issues it seems, didn't work for a few tries, then looked at https://registry.npmjs.org (webpage worked fine), tried again, tried again and then it worked.

Ensure you have an index on your firstname and lastname columns and go with 1. This really won't have much of a performance impact at all.
EDIT: After @Dems comment regarding spamming the plan cache ,a better solution might be to create a computed column on the existing table (or a separate view) which contained a concatenated Firstname + Lastname value, thus allowing you to execute a query such as
SELECT City
FROM User
WHERE Fullname in (@fullnames)
where @fullnames
looks a bit like "'JonDoe', 'JaneDoe'"
etc

This is based on the answer of @Dejan but now it's quite easy to add the OR as well. I chose not to make the Combine
function public, but you could do that to be even more flexible.
public static class ExpressionExtensions
{
public static Expression<Func<T, bool>> AndAlso<T>(this Expression<Func<T, bool>> leftExpression,
Expression<Func<T, bool>> rightExpression) =>
Combine(leftExpression, rightExpression, Expression.AndAlso);
public static Expression<Func<T, bool>> Or<T>(this Expression<Func<T, bool>> leftExpression,
Expression<Func<T, bool>> rightExpression) =>
Combine(leftExpression, rightExpression, Expression.Or);
public static Expression<Func<T, bool>> Combine<T>(Expression<Func<T, bool>> leftExpression, Expression<Func<T, bool>> rightExpression, Func<Expression, Expression, BinaryExpression> combineOperator)
{
var leftParameter = leftExpression.Parameters[0];
var rightParameter = rightExpression.Parameters[0];
var visitor = new ReplaceParameterVisitor(rightParameter, leftParameter);
var leftBody = leftExpression.Body;
var rightBody = visitor.Visit(rightExpression.Body);
return Expression.Lambda<Func<T, bool>>(combineOperator(leftBody, rightBody), leftParameter);
}
private class ReplaceParameterVisitor : ExpressionVisitor
{
private readonly ParameterExpression _oldParameter;
private readonly ParameterExpression _newParameter;
public ReplaceParameterVisitor(ParameterExpression oldParameter, ParameterExpression newParameter)
{
_oldParameter = oldParameter;
_newParameter = newParameter;
}
protected override Expression VisitParameter(ParameterExpression node)
{
return ReferenceEquals(node, _oldParameter) ? _newParameter : base.VisitParameter(node);
}
}
}
Usage is not changed and still like this:
Expression<Func<Result, bool>> noFilterExpression = item => filters == null;
Expression<Func<Result, bool>> laptopFilterExpression = item => item.x == ...
Expression<Func<Result, bool>> dateFilterExpression = item => item.y == ...
var combinedFilterExpression = noFilterExpression.Or(laptopFilterExpression.AndAlso(dateFilterExpression));
efQuery.Where(combinedFilterExpression);
(This is an example based on my actual code, but read is as pseudo-code)
I had the same issue with firefox, when I searched for a solution I didn't find anything, but then I tried to load the script from a cdn, it worked properly, so I think you should try loading it from a cdn link, I mean if you are trying to load a script that you havn't created. because in my case, when tried to load a script that is mine, it worked and imported successfully, for now I don't know why, but I think there is something in the scripts from network, so just try cdn, you won't lose anything.
I wish it help you.
SELECT * from games WHERE (lower(title) LIKE 'age of empires III');
The above query doesn't return any rows because you're looking for 'age of empires III' exact string which doesn't exists in any rows.
So in order to match with this string with different string which has 'age of empires'
as substring you need to use '%your string goes here%'
More on mysql string comparision
You need to try this
SELECT * from games WHERE (lower(title) LIKE '%age of empires III%');
In Like '%age of empires III%'
this will search for any matching substring in your rows, and it will show in results.
This is the resolution of the screen that the given component is currently assigned (something like most part of the root window is visible on that screen).
public Rectangle getCurrentScreenBounds(Component component) {
return component.getGraphicsConfiguration().getBounds();
}
Usage:
Rectangle currentScreen = getCurrentScreenBounds(frameOrWhateverComponent);
int currentScreenWidth = currentScreen.width // current screen width
int currentScreenHeight = currentScreen.height // current screen height
// absolute coordinate of current screen > 0 if left of this screen are further screens
int xOfCurrentScreen = currentScreen.x
If you want to respect toolbars, etc. you'll need to calculate with this, too:
GraphicsConfiguration gc = component.getGraphicsConfiguration();
Insets screenInsets = Toolkit.getDefaultToolkit().getScreenInsets(gc);
If you already have onChange handler for the individual FieldEditors I don't see why you couldn't just move the state up to the FormEditor component and just pass down a callback from there to the FieldEditors that will update the parent state. That seems like a more React-y way to do it, to me.
Something along the line of this perhaps:
const FieldEditor = ({ value, onChange, id }) => {
const handleChange = event => {
const text = event.target.value;
onChange(id, text);
};
return (
<div className="field-editor">
<input onChange={handleChange} value={value} />
</div>
);
};
const FormEditor = props => {
const [values, setValues] = useState({});
const handleFieldChange = (fieldId, value) => {
setValues({ ...values, [fieldId]: value });
};
const fields = props.fields.map(field => (
<FieldEditor
key={field}
id={field}
onChange={handleFieldChange}
value={values[field]}
/>
));
return (
<div>
{fields}
<pre>{JSON.stringify(values, null, 2)}</pre>
</div>
);
};
// To add abillity to dynamically add/remove fields keep the list in state
const App = () => {
const fields = ["field1", "field2", "anotherField"];
return <FormEditor fields={fields} />;
};

Okay, most things should be clear so far... the tricky part is the SQL: if it is not in reality running in another thread or process in it’s entirety, the SQL-execution has to be broken down into individual steps (by an SQL processor made for asynchronous execution!), where the non-blocking ones are executed, and the blocking ones (e.g. the sleep) actually can be transferred to the kernel (as an alarm interrupt/event) and put on the event list for the main loop.
That means, e.g. the interpretation of the SQL, etc. is done immediately, but during the wait (stored as an event to come in the future by the kernel in some kqueue, epoll, ... structure; together with the other IO operations) the main loop can do other things and eventually check if something happened of those IOs and waits.
So, to rephrase it again: the program is never (allowed to get) stuck, sleeping calls are never executed. Their duty is done by the kernel (write something, wait for something to come over the network, waiting for time to elapse) or another thread or process. – The Node process checks if at least one of those duties is finished by the kernel in the only blocking call to the OS once in each event-loop-cycle. That point is reached, when everything non-blocking is done.
Clear? :-)
I don’t know Node. But where does the c.query come from?

One needs to understand what a JOIN or a series of JOINs does to a set of data. With strae's post, a pe_id of 1 joined with corresponding order and items on pe_id = 1 will give you the following data to "select" from:
[ table people portion ] [ table orders portion ] [ table items portion ]
| people.pe_id | people.pe_name | orders.ord_id | orders.pe_id | orders.ord_title | item.item_id | item.ord_id | item.pe_id | item.title |
| 1 | Foo | 1 | 1 | First order | 1 | 1 | 1 | Apple |
| 1 | Foo | 1 | 1 | First order | 2 | 1 | 1 | Pear |
The joins essentially come up with a cartesian product of all the tables. You basically have that data set to select from and that's why you need a distinct count on orders.ord_id and items.item_id. Otherwise both counts will result in 2 - because you effectively have 2 rows to select from.

Completing @d13 and the comments by @johnny-oshika and @DanyalAytekin:
I guess in the example provided by @johnny-oshika we could use normal functions instead of arrow functions and then .bind
them with the current object plus a _privates
object as a curried parameter:
something.js
function _greet(_privates) {
return 'Hello ' + _privates.message;
}
function _updateMessage(_privates, newMessage) {
_privates.message = newMessage;
}
export default class Something {
constructor(message) {
const _privates = {
message
};
this.say = _greet.bind(this, _privates);
this.updateMessage = _updateMessage.bind(this, _privates);
}
}
main.js
import Something from './something.js';
const something = new Something('Sunny day!');
const message1 = something.say();
something.updateMessage('Cloudy day!');
const message2 = something.say();
console.log(message1 === 'Hello Sunny day!'); // true
console.log(message2 === 'Hello Cloudy day!'); // true
// the followings are not public
console.log(something._greet === undefined); // true
console.log(something._privates === undefined); // true
console.log(something._updateMessage === undefined); // true
// another instance which doesn't share the _privates
const something2 = new Something('another Sunny day!');
const message3 = something2.say();
console.log(message3 === 'Hello another Sunny day!'); // true
Benefits I can think of:
_greet
and _updateMessage
act like private methods as long as we don't export
the references) _privates

Here's my working Async Pure Javascript from 2020
function testFileExists(src, successFunc, failFunc) {
var xhr = new XMLHttpRequest();
xhr.onreadystatechange = function () {
if (this.readyState === this.DONE) {
if (xhr.status === 200) {
successFunc(xhr);
} else {
failFunc(xhr);
}
}
}
// xhr.error = function() {
// failFunc(xhr);
// }
// xhr.onabort = function() {
// failFunc(xhr);
// }
// xhr.timeout = function() {
// failFunc(xhr);
// }
xhr.timeout = 5000; // TIMEOUT SET TO PREFERENCE (5 SEC)
xhr.open('HEAD', src, true);
xhr.send(null); // VERY IMPORTANT
}
function fileExists(xhr) {
alert("File exists !! Yay !!");
}
function fileNotFound(xhr) {
alert("Cannot find the file, bummer");
}
testFileExists("test.html", fileExists, fileNotFound);
I could not force it to come back with any of the abort, error, or timeout callbacks. Each one of these returned a main status code of 0, in the test above, so I removed them. You can experiment. I set the timeout to 5 seconds as the default seems to be very excessive. With the Async call, it doesn't seem to do anything without the send() command.
If using Visual Studio 2010 you can right-click on the project for the service, and select properties

section you can configure the URL. There is also a button to create the virtual directory.
What you show looks like a mesh warp. That would be straightforward using OpenGL, but "straightforward OpenGL" is like straightforward rocket science.
I wrote an iOS app for my company called Face Dancerthat's able to do 60 fps mesh warp animations of video from the built-in camera using OpenGL, but it was a lot of work. (It does funhouse mirror type changes to faces - think "fat booth" live, plus lots of other effects.)
It all depends what type of tag you want to create:
git tag -a v1.0.0
.git tag v1.0.0
.There are a few other tag functionalities such as:
git tag -l -n3
. The command lists all existing tags with maximum 3 lines of their tag message. By default -n only shows the first line.git show <tag_identifier>
. It shows all you need to know about a specific tag.git tag --sort=<type>
git push origin v1.0
. You can git push the tag individually, or you can run git push --tags which will push all tags at once. Be sure to check this tag related article for more relevant information.

If you want to change a value in a method call within an anonymous class, that "value" is actually a Future
. So, if you use Guava, you can write
...
final SettableFuture<Integer> myvalue = SettableFuture<Integer>.create();
...
someclass.run(new Runnable(){
public void run(){
...
myvalue.set(value);
...
}
}
return myvalue.get();
Here's a batch file, called base64encode.bat, that encodes base64.

:arg1exists
set base64out=%2
if "%base64out%" == "" set base64out=con
(
set base64tmp=base64.tmp
certutil -encode "%1" %base64tmp% > nul

erase %base64tmp%
) > %base64out%
You might want to use the Event Log ! Here's how to access it from C# http://support.microsoft.com/kb/307024/en
But whatever is the method that you will use, I'd recommend to output to a file every time something is appended to the log rather than when your process exits, so you won't lose data in the case of crash or if your process is killed.
If you want to bind to another property on the object:
{Binding Path=PathToProperty, RelativeSource={RelativeSource Self}}
If you want to get a property on an ancestor:
{Binding Path=PathToProperty,
RelativeSource={RelativeSource AncestorType={x:Type typeOfAncestor}}}
If you want to get a property on the templated parent (so you can do 2 way bindings in a ControlTemplate)
{Binding Path=PathToProperty, RelativeSource={RelativeSource TemplatedParent}}
or, shorter (this only works for OneWay bindings):
{TemplateBinding Path=PathToProperty}
The parseInt solution is the best way to go as it is clear what is happening.
For completeness it is worth mentioning that this can also be done with the + operator
$('.load_more').live("click",function() { //When user clicks
var newcurrentpageTemp = +$(this).attr("id") + 1; //Get the id from the hyperlink
alert(newcurrentpageTemp);
dosomething();
});
You can make the SharedPrefences
in onAttach
method of fragment like this:
@Override
public void onAttach(Context context) {
super.onAttach(context);
SharedPreferences preferences = context.getSharedPreferences("pref", 0);
}
worked for me too:
SimpleDateFormat sdf = new SimpleDateFormat("dd/MM/yyyy");
Date parsed = null;
try {
parsed = sdf.parse("02/01/2014");
} catch (ParseException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
java.sql.Date data = new java.sql.Date(parsed.getTime());
contato.setDataNascimento( data);
// Contato DataNascimento era Calendar
//contato.setDataNascimento(Calendar.getInstance());
// grave nessa conexão!!!
ContatoDao dao = new ContatoDao("mysql");
// método elegante
dao.adiciona(contato);
System.out.println("Banco: ["+dao.getNome()+"] Gravado! Data: "+contato.getDataNascimento());

It's like asking what's the benefit of a hammer over a screwdriver. At an extremely high level, both do essentially the same thing, but at the implementation level it's important to select the optimal tool for what you're trying to accomplish. There are tasks that are difficult and time-consuming in c# but easy in f# - like trying to pound a nail with a screwdriver. You can do it, for sure - it's just not ideal.
Data manipulation is one example I can personally point to where f# really shines and c# can potentially be unwieldy. On the flip side, I'd say (generally speaking) complex stateful UI is easier in OO (c#) than functional (f#). (There would probably be some people who disagree with this since it's "cool" right now to "prove" how easy it is to do anything in F#, but I stand by it). There are countless others.
short but sweet upvote if it works for you.
select * from information_schema.key_column_usage where constraint_catalog=current_catalog and table_name='your_table_name' and position_in_unique_constraint notnull;
One example is when you write a parser function and pass it a source pointer to read from, if the function is supposed to push that pointer forward behind the last character which has been correctly recognized by the parser. Using a reference to a pointer makes it clear then that the function will move the original pointer to update its position.
In general, you use references to pointers if you want to pass a pointer to a function and let it move that original pointer to some other position instead of just moving a copy of it without affecting the original.
The way I know how to convert an integer into a string is by using the following code:
Integer.toString(int);
and
String.valueOf(int);
If you had an integer i, and a string s, then the following would apply:
int i;
String s = Integer.toString(i); or
String s = String.valueOf(i);
If you wanted to convert a string "s" into an integer "i", then the following would work:
i = Integer.valueOf(s).intValue();
There's no way to initiate a file transfer back to/from local Windows from a SSH session opened in PuTTY window.
Though PuTTY supports connection-sharing.
While you still need to run a compatible file transfer client (the pscp
or psftp
), no new login is required, it automatically (if enabled) makes use of an existing PuTTY session.
To enable the sharing see:
Sharing an SSH connection between PuTTY tools.
Alternative way is to use WinSCP, a GUI SFTP/SCP client. While you browse the remote site, you can anytime open SSH terminal to the same site using Open in PuTTY button.
With an additional setup, you can even make PuTTY automatically navigate to the same directory you are browsing with WinSCP.
See Opening PuTTY in the Same Directory.

Typically we would place one of these at or near the top of the script. Scripts that parse their command lines would do the redirection after parsing.
Send stdout to a file
exec > file
with stderr
exec > file
exec 2>&1
append both stdout and stderr to file
exec >> file
exec 2>&1
As Jonathan Leffler mentioned in his comment:
exec
has two separate jobs. The first one is to replace the currently executing shell (script) with a new program. The other is changing the I/O redirections in the current shell. This is distinguished by having no argument to exec
.

Typescript 2.1 introduces Mapped Types and provides Partial<T>
, which allows you to do this....
class Person {
public name: string = "default"
public address: string = "default"
public age: number = 0;
public constructor(init?:Partial<Person>) {
Object.assign(this, init);
}
}

new Person(),
new Person({}),
new Person({name:"John"}),
new Person({address:"Earth"}),
new Person({age:20, address:"Earth", name:"John"}),

variable that you pass to the constructor. The trick is to redefine all the class fields for this initialiser as optional. When the object is created (with its defaults) you simply assign the initialiser object onto this
;
export class Person {
public name: string = "default"
public address: string = "default"
public age: number = 0;
public constructor(
fields?: {
name?: string,
address?: string,
age?: number
}) {
if (fields) Object.assign(this, fields);
}
}
or do it manually (bit more safe):
if (fields) {
this.name = fields.name || this.name;
this.address = fields.address || this.address;
this.age = fields.age || this.age;
}
usage:
let persons = [
new Person(),
new Person({name:"Joe"}),
new Person({
name:"Joe",
address:"planet Earth"
}),
new Person({
age:5,
address:"planet Earth",
name:"Joe"
}),
new Person(new Person({name:"Joe"})) //shallow clone
];
and console output:
Person { name: 'default', address: 'default', age: 0 }
Person { name: 'Joe', address: 'default', age: 0 }
Person { name: 'Joe', address: 'planet Earth', age: 0 }
Person { name: 'Joe', address: 'planet Earth', age: 5 }
Person { name: 'Joe', address: 'default', age: 0 }
This gives you basic safety and property initialization, but its all optional and can be out-of-order. You get the class's defaults left alone if you don't pass a field.
You can also mix it with required constructor parameters too -- stick fields
on the end.
About as close to C# style as you're going to get I think (actual field-init syntax was rejected). I'd much prefer proper field initialiser, but doesn't look like it will happen yet.
For comparison, If you use the casting approach, your initialiser object must have ALL the fields for the type you are casting to, plus don't get any class specific functions (or derivations) created by the class itself.
If you are using HTML 5, there is the <audio>
element.
On MDN:
The
audio
element is used to embed sound content in an HTML or XHTML document. The audio element was added as part of HTML5.
Update:
In order to play audio in the browser in HTML versions before 5 (including XHTML), you need to use one of the many flash audio players.
You could do something using the grep command:
find . | grep -v '(dll|exe)$'
The -v
flag on grep
specifically means "find things that don't match this expression."
Got it working! I should have been building a JSONArray
of JSONObject
s and then add the array to a final "Addresses" JSONObject
. Observe the following:
JSONObject json = new JSONObject();
JSONArray addresses = new JSONArray();
JSONObject address;
try
{
int count = 15;
for (int i=0 ; i<count ; i++)
{
address = new JSONObject();
address.put("CustomerName" , "Decepticons" + i);
address.put("AccountId" , "1999" + i);
address.put("SiteId" , "1888" + i);
address.put("Number" , "7" + i);
address.put("Building" , "StarScream Skyscraper" + i);
address.put("Street" , "Devestator Avenue" + i);
address.put("City" , "Megatron City" + i);
address.put("ZipCode" , "ZZ00 XX1" + i);
address.put("Country" , "CyberTron" + i);
addresses.add(address);
}
json.put("Addresses", addresses);
}
catch (JSONException jse)
{
}
response.setContentType("application/json");
response.getWriter().write(json.toString());
This worked and returned valid and parse-able JSON. Hopefully this helps someone else in the future. Thanks for your help Marcel
Modern way that both is straight-forward and does not lose the ability to undo (Ctrl+Z) the last changes.
$('#your-textarea').keydown(function (e) {
var keyCode = e.keyCode || e.which;
if (keyCode === $.ui.keyCode.TAB) {
e.preventDefault();
const TAB_SIZE = 4;
// The one-liner that does the magic
document.execCommand('insertText', false, ' '.repeat(TAB_SIZE));
}
});
More about execCommand
:
As pointed out in the comment (and while this was once a "modern" solution), the feature has gone obsolete. Quoting the docs:
This feature is obsolete. Although it may still work in some browsers, its use is discouraged since it could be removed at any time. Try to avoid using it.
A few years late but this might help someone if you are using eval or backtick substitution:
postDataJson="{\"guid\":\"$guid\",\"auth_token\":\"$token\"}"
Using sed to strip quotes from beginning and end of response
$(curl --silent -H "Content-Type: application/json" https://${target_host}/runs/get-work -d ${postDataJson} | sed -e 's/^"//' -e 's/"$//')
On my Mac this is what worked for me
You are good to go and can now run your project
the tutorial of how to build NodeJS for Android https://github.com/dna2github/dna2oslab/tree/master/android/build
there are several versions v0.12, v4, v6, v7
It is easy to run compiled binary on Android; for example run compiled Nginx: https://github.com/dna2github/dna2mtgol/tree/master/fileShare
You just need to modify code to replace Nginx to NodeJS; it is better if using Android Service to run node js server on the backend.
Like codehead said, you'd have to iterate over the array indices instead of its elements. I prefer this variant over the C-style for
loop:
for my $i (0 .. $#x) {
print "$i: $x[$i]\n";
}
f=imread(...);
h=fspecial('average', [3 3]);
g= imfilter(f, h);
imshow(g);
You can implement a class that holds the fields you have in your JSON
class MyData
{
public string t;
public bool a;
public object[] data;
public string[][] type;
}
and then use the generic version of DeserializeObject:
MyData tmp = JsonConvert.DeserializeObject<MyData>(json);
foreach (string typeStr in tmp.type[0])
{
// Do something with typeStr
}

The difference is that in the first case the retrieved user is not tracked by the context so when you are going to save the user back to database you must attach it and set correctly state of the user so that EF knows that it should update existing user instead of inserting a new one. In the second case you don't need to do that if you load and save the user with the same context instance because the tracking mechanism handles that for you.
And of course for auto indentation and formatting, following the language you're using, you can see which good extensions do the good job, and which formatters to install or which parameters settings to enable or set for each language and its available tools. Just make sure to read well the documentation of the extension, to install and set all what it need.
Up to now the indentation problem bothers me with Python when copy pasting a block of code. If that's the case, here is how you solve that: Visual Studio Code indentation for Python
If you're looking for an address (IPv4) of the specific interface say wlan0 then try this code which uses getifaddrs():
#include <arpa/inet.h>
#include <sys/socket.h>
#include <netdb.h>
#include <ifaddrs.h>
#include <stdio.h>
#include <stdlib.h>
#include <unistd.h>
#include <string.h>
int main(int argc, char *argv[])
{
struct ifaddrs *ifaddr, *ifa;
int family, s;
char host[NI_MAXHOST];
if (getifaddrs(&ifaddr) == -1)
{
perror("getifaddrs");
exit(EXIT_FAILURE);
}
for (ifa = ifaddr; ifa != NULL; ifa = ifa->ifa_next)
{
if (ifa->ifa_addr == NULL)
continue;
s=getnameinfo(ifa->ifa_addr,sizeof(struct sockaddr_in),host, NI_MAXHOST, NULL, 0, NI_NUMERICHOST);
if((strcmp(ifa->ifa_name,"wlan0")==0)&&(ifa->ifa_addr->sa_family==AF_INET))
{
if (s != 0)
{
printf("getnameinfo() failed: %s\n", gai_strerror(s));
exit(EXIT_FAILURE);
}
printf("\tInterface : <%s>\n",ifa->ifa_name );
printf("\t Address : <%s>\n", host);
}
}
freeifaddrs(ifaddr);
exit(EXIT_SUCCESS);
}
You can replace wlan0 with eth0 for ethernet and lo for local loopback.

This code is probably good for Python 2. But in Python 3, this will cause an issue, something related to bit encoding. I was trying to make a simple TCP server and encountered the same problem. Encoding worked for me. Try this with sendto
command.
clientSocket.sendto(message.encode(),(serverName, serverPort))
Similarly you would use .decode()
to receive the data on the UDP server side, if you want to print it exactly as it was sent.
Try calling the image in a <DIV>
tag, which will allow a smoother and faster loading time. Take note that because this is a background image, you can also put text over the image between the <DIV></DIV>
tags. This works great for custom store/shop listings as well...to post a cool " Sold Out! " overlay, or whatever you might want.
Here is the pic/text- sided by side version, which can be used for blog post and article listing:
<div class="whatever_container">
<h2>Title/Header Here</h2>
<div id="image-container-name"style="background-image:url('images/whatever-this-is-named.jpg');background color:#FFFFFF;height:75px;width:20%;float:left;margin:0px 25px 0px 5px;"></div>
<p>All of your text goes here next to the image.</p></div>
What do you want to fade? The background
or color
attribute?
Currently you're changing the background color, but telling it to transition the color property. You can use all
to transition all properties.
.clicker {
-moz-transition: all .2s ease-in;
-o-transition: all .2s ease-in;
-webkit-transition: all .2s ease-in;
transition: all .2s ease-in;
background: #f5f5f5;
padding: 20px;
}
.clicker:hover {
background: #eee;
}
Otherwise just use transition: background .2s ease-in
.
There are two possible reasons for that error:
try to put your jquery code in document.ready, like this:
$(document).ready(function(){

Change
private void Form1_Load(object sender, EventArgs e)
{
CERas.CERAS = new CERas.CERAS();
}
to
private void Form1_Load(object sender, EventArgs e)
{
CERas.CERAS c = new CERas.CERAS();
}
Or if you wish to use it later again
change it to
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
namespace WinApp_WMI2
{
public partial class Form1 : Form
{
CERas.CERAS m_CERAS;
public Form1()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
m_CERAS = new CERas.CERAS();
}
}
}
Two solutions
1. use merge if you want to update the object
2. use save if you want to just save new object (make sure identity is null to let hibernate or database generate it)
3. if you are using mapping like
@OneToOne(fetch = FetchType.EAGER,cascade=CascadeType.ALL)
@JoinColumn(name = "stock_id")
Then use CascadeType.ALL to CascadeType.MERGE

I think you're using the best method, though you could optimize it to:
$("<div/>");
Try Runscope. A free tool sampling their service is provided at https://www.hurl.it/ . You can set the method, authentication, headers, parameters, and body. Response shows status code, headers, and body. The response body can be formatted from JSON with a collapsable heirarchy. Paid accounts can automate test API calls and use return data to build new test calls. COI disclosure: I have no relationship to Runscope.
I'm not with computer,so I write a draft. You might be clear of what I say.
func main(){
const dir = "/etc/"
filesInfo, e := ioutil.ReadDir(dir)
var fileNames = make([]string, 0, 10)
for i,v:=range filesInfo{
if !v.IsDir() {
fileNames = append(fileNames, v.Name())
}
}
var fileNumber = len(fileNames)
var contents = make([]string, fileNumber, 10)
wg := sync.WaitGroup{}
wg.Add(fileNumber)
for i,_:=range content {
go func(i int){
defer wg.Done()
buf,e := ioutil.Readfile(fmt.Printf("%s/%s", dir, fileName[i]))
defer file.Close()
content[i] = string(buf)
}(i)
}
wg.Wait()
}
Based on the answer by @Jeff, refactored to use a classmethod
so that you can reuse the same code for any of your enums:
from enum import Enum
class ExtendedEnum(Enum):
@classmethod
def list(cls):
return list(map(lambda c: c.value, cls))
class OperationType(ExtendedEnum):
CREATE = 'CREATE'
STATUS = 'STATUS'
EXPAND = 'EXPAND'
DELETE = 'DELETE'
print(OperationType.list())
Produces:
['CREATE', 'STATUS', 'EXPAND', 'DELETE']
Apparently mine is that Haskell has variables. This is both "trivial" (according to at least eight SO users) (though nobody can seem to agree on which trivial answer is correct), and a bad question even to ask (according to at least five downvoters and four who voted to close it). Oh, and I (and computing scientests and mathematicians) am wrong, though nobody can provide me a detailed explanation of why.
to update your branch from the master:
git checkout master
git pull
git checkout your_branch
git merge master
string startTime = "7:00 AM";
string endTime = "2:00 PM";
TimeSpan duration = DateTime.Parse(endTime).Subtract(DateTime.Parse(startTime));
Console.WriteLine(duration);
Console.ReadKey();
Will output: 07:00:00.
It also works if the user input military time:
string startTime = "7:00";
string endTime = "14:00";
TimeSpan duration = DateTime.Parse(endTime).Subtract(DateTime.Parse(startTime));
Console.WriteLine(duration);
Console.ReadKey();
Outputs: 07:00:00.
To change the format: duration.ToString(@"hh\:mm")

Addendum:
Over the years it has somewhat bothered me that this is the most popular answer I have ever given; the original answer never actually explained why the OP's code didn't work despite the fact that it is perfectly valid. The only reason it gets so many votes is because the post comes up on Google when people search for a combination of the terms "C#", "timespan", and "between".
The code you posted starts three different processes each with it's own command. To open a command prompt and then run a command try the following (never tried it myself):
try {
// Execute command
String command = "cmd /c start cmd.exe";
Process child = Runtime.getRuntime().exec(command);
// Get output stream to write from it
OutputStream out = child.getOutputStream();
out.write("cd C:/ /r/n".getBytes());
out.flush();
out.write("dir /r/n".getBytes());
out.close();
} catch (IOException e) {
}
I already came across the texotela plugin mentioned, which let me solve it like this:
$(document).ready(function(){
if ( $("#context").selectedValues() == false) {
$("#context").selectOptions("71");
}
});
void intSwap (int *pa, int *pb){
int temp = *pa;
*pa = *pb;
*pb = temp;
}
You need to know the following -
int a = 5; // an integer, contains value
int *p; // an integer pointer, contains address
p = &a; // &a means address of a
a = *p; // *p means value stored in that address, here 5
void charSwap(char* a, char* b){
char temp = *a;
*a = *b;
*b = temp;
}
So, when you swap like this. Only the value will be swapped. So, for a char*
only their first char
will swap.
Now, if you understand char* (string) clearly, then you should know that, you only need to exchange the pointer. It'll be easier to understand if you think it as an array
instead of string.
void stringSwap(char** a, char** b){
char *temp = *a;
*a = *b;
*b = temp;
}
So, here you are passing double pointer because starting of an array
itself is a pointer.
Try this I think this is better.

@Espo: I just have to say that regex is incredible. I'd hate to have to write the code that did something useful with the matches, such as if you wanted to actually find out what date and time the user typed.
It seems like Tom's solution would be more tenable, as it is about a zillion times simpler and with the addition of some parentheses you can easily get at the values the user typed:
(\d{4})-(\d{2})-(\d{2}) (\d{2}):(\d{2}):(\d{2})
If you're using perl, then you can get the values out with something like this:
$year = $1;
$month = $2;
$day = $3;
$hour = $4;
$minute = $5;
$second = $6;
Other languages will have a similar capability. Note that you will need to make some minor mods to the regex if you want to accept values such as single-digit months.
FYI Under certain network conditions your hostname may change or be incorrect. If you are on a mac the following will let you set your hostname fairly permanently:
sudo scutil --set HostName correct-name
create a folder inside htdocs, place your website there, access it via localhost or Internal IP (if you're behind a router) - check out this video demo here
Try this:
runas.exe /savecred /user:administrator "%sysdrive%\testScripts\testscript1.ps1"
It saves the password the first time and never asks again. Maybe when you change the administrator password you will be prompted again.
Yes, you can assign one instance of a struct to another using a simple assignment statement.
In the case of non-pointer or non pointer containing struct members, assignment means copy.
In the case of pointer struct members, assignment means pointer will point to the same address of the other pointer.
Let us see this first hand:
#include <stdio.h>
struct Test{
int foo;
char *bar;
};
int main(){
struct Test t1;
struct Test t2;
t1.foo = 1;
t1.bar = malloc(100 * sizeof(char));
strcpy(t1.bar, "t1 bar value");
t2.foo = 2;
t2.bar = malloc(100 * sizeof(char));
strcpy(t2.bar, "t2 bar value");
printf("t2 foo and bar before copy: %d %s\n", t2.foo, t2.bar);
t2 = t1;// <---- ASSIGNMENT
printf("t2 foo and bar after copy: %d %s\n", t2.foo, t2.bar);
//The following 3 lines of code demonstrate that foo is deep copied and bar is shallow copied
strcpy(t1.bar, "t1 bar value changed");
t1.foo = 3;
printf("t2 foo and bar after t1 is altered: %d %s\n", t2.foo, t2.bar);
return 0;
}
Why do you want a textarea to submit when you hit enter?
A "text" input will submit by default when you press enter. It is a single line input.
<input type="text" value="...">
A "textarea" will not, as it benefits from multi-line capabilities. Submitting on enter takes away some of this benefit.
<textarea name="area"></textarea>
You can add JavaScript code to detect the enter keypress and auto-submit, but you may be better off using a text input.
Based on the comments above, here is a simple test:
isunset() { [[ "${!1}" != 'x' ]] && [[ "${!1-x}" == 'x' ]] && echo 1; }
isset() { [ -z "$(isunset "$1")" ] && echo 1; }
Example:
$ unset foo; [[ $(isunset foo) ]] && echo "It's unset" || echo "It's set"
It's unset
$ foo= ; [[ $(isunset foo) ]] && echo "It's unset" || echo "It's set"
It's set
$ foo=bar ; [[ $(isunset foo) ]] && echo "It's unset" || echo "It's set"
It's set
I know this is an old question, but with my quick read of the responses here, I didn't really see anyone mention that at times a synchronized
method may be the wrong lock.
From Java Concurrency In Practice (pg. 72):
public class ListHelper<E> {
public List<E> list = Collections.syncrhonizedList(new ArrayList<>());
...
public syncrhonized boolean putIfAbsent(E x) {
boolean absent = !list.contains(x);
if(absent) {
list.add(x);
}
return absent;
}
The above code has the appearance of being thread-safe. However, in reality it is not. In this case the lock is obtained on the instance of the class. However, it is possible for the list to be modified by another thread not using that method. The correct approach would be to use
public boolean putIfAbsent(E x) {
synchronized(list) {
boolean absent = !list.contains(x);
if(absent) {
list.add(x);
}
return absent;
}
}
The above code would block all threads trying to modify list from modifying the list until the synchronized block has completed.
It is super easy by changing the heap size as it was mentioned. Just easily by going to Pycharm HELP -> Edit custom VM option ... and change it to:
-Xms2048m
-Xmx2048m
Change your default controller which is in config file.
i.e : config/routes.php
$route['default_controller'] = "Your controller name";
Hope this will help.
The escape code "
can also be used instead of "
.
The cleanest approach is to copy the list and then insert the object into the copy. On Python 3 this can be done via list.copy
:
new = old.copy()
new.insert(index, value)
On Python 2 copying the list can be achieved via new = old[:]
(this also works on Python 3).
In terms of performance there is no difference to other proposed methods:
$ python --version
Python 3.8.1
$ python -m timeit -s "a = list(range(1000))" "b = a.copy(); b.insert(500, 3)"
100000 loops, best of 5: 2.84 µsec per loop
$ python -m timeit -s "a = list(range(1000))" "b = a.copy(); b[500:500] = (3,)"
100000 loops, best of 5: 2.76 µsec per loop
For those who dont want to use datepicker method

var yyyy = today.getFullYear();
if(dd<10) {

}
if(mm<10) {
mm='0'+mm
}
today = mm+'/'+dd+'/'+yyyy;
if(value!=''){
if(value>today){

}
}
});
Git has two types of branches: local
and remote
. To use git pull
and git push
as you'd like, you have to tell your local branch (my_test
) which remote branch it's tracking. In typical Git fashion this can be done in both the config file and with commands.
Commands
Make sure you're on your master
branch with
1)git checkout master
then create the new branch with
2)git branch --track my_test origin/my_test
and check it out with
3)git checkout my_test
.
You can then push
and pull
without specifying which local and remote.
However if you've already created the branch then you can use the -u
switch to tell git's push
and pull
you'd like to use the specified local and remote branches from now on, like so:
git pull -u my_test origin/my_test
git push -u my_test origin/my_test
Config
The commands to setup remote branch tracking are fairly straight forward but I'm listing the config way as well as I find it easier if I'm setting up a bunch of tracking branches. Using your favourite editor open up your project's .git/config
and add the following to the bottom.
[remote "origin"]
url = [email protected]:username/repo.git
fetch = +refs/heads/*:refs/remotes/origin/*
[branch "my_test"]
remote = origin
merge = refs/heads/my_test
This specifies a remote called origin
, in this case a GitHub style one, and then tells the branch my_test
to use it as it's remote.
You can find something very similar to this in the config after running the commands above.
Some useful resources:
Thanks for the solution !
It works, but in a french Excel environment, you should apply something like
TEXTE(F2;"jj/mm/aaaa")
to get the date preserved as it is displayed in F2 cell, after concatenation. Best Regards
I know this is a very old thread but I was looking for a solution to the same problem and I came across this before eventually finding the answer and I wanted to just post it here so somebody else in my shoes would have a shorter trek across the internet.
****Note that you probably have to run cmd.exe as an administrator for this to work**
So here we go, open up the prompt (as an adminstrator) and go to your System32 directory. Then run
C:\Windows\System32>cd ras
Now you'll be in the ras directory. Now it's time to create a temporary file with our connection info that we will then append onto the rasphone.pbk file that will allow us to use the rasdial command.
So to create our temp file run:
C:\Windows\System32\ras>copy con temp.txt
Now it will let you type the contents of the file, which should look like this:
[CONNECTION NAME]
MEDIA=rastapi
Port=VPN2-0
Device=WAN Miniport (IKEv2)
DEVICE=vpn
PhoneNumber=vpn.server.address.com
So replace CONNECTION NAME and vpn.server.address.com with the desired connection name and the vpn server address you want.
Make a new line and press Ctrl+Z to finish and save.
Now we will append this onto the rasphone.pbk file that may or may not exist depending on if you already have network connections configured or not. To do this we will run the following command:
C:\Windows\System32\ras>type temp.txt >> rasphone.pbk
This will append the contents of temp.txt to the end of rasphone.pbk, or if rasphone.pbk doesn't exist it will be created. Now we might as well delete our temp file:
C:\Windows\System32\ras>del temp.txt
Now we can connect to our newly configured VPN server with the following command:
C:\Windows\System32\ras>rasdial "CONNECTION NAME" myUsername myPassword
When we want to disconnect we can run:
C:\Windows\System32\ras>rasdial /DISCONNECT
That should cover it! I've included a direct copy and past from the command line of me setting up a connection for and connecting to a canadian vpn server with this method:

As of C# 8 you can use the 'empty' property pattern (with pattern matching) to ensure an object is not null:
if (obj is { })
{
// 'obj' is not null here
}
This approach means "if the object references an instance of something" (i.e. it's not null).
You can think of this as the opposite of: if (obj is null)...
. which will return true when the object does not reference an instance of something.
For more info on patterns in C# 8.0 read here.
Result has an optional $type
parameter which decides what type of result is returned. By default ($type = "object"
), it returns an object (result_object()
). It can be set to "array"
, then it will return an array of result, that being equivalent of caling result_array()
. The third version accepts a custom class to use as a result object.
The code from CodeIgniter:
/**
* Query result. Acts as a wrapper function for the following functions.
*
* @param string $type 'object', 'array' or a custom class name
* @return array
*/
public function result($type = 'object')
{
if ($type === 'array')
{
return $this->result_array();
}
elseif ($type === 'object')
{
return $this->result_object();
}
else
{
return $this->custom_result_object($type);
}
}
Arrays are technically faster, but they are not objects. It depends where do you want to use the result. Most of the time, arrays are sufficient.
According to the MDN reference page, includes
is not supported on Internet Explorer. The simplest alternative is to use indexOf
, like this:
if(window.location.hash.indexOf("?") >= 0) {
...
}
Your function has a couple of smallint
parameters.
But in the call, you are using numeric literals that are presumed to be type integer
.
A string literal or string constant ('123'
) is not typed immediately. It remains type "unknown" until assigned or cast explicitly.
However, a numeric literal or numeric constant is typed immediately. Per documentation:
A numeric constant that contains neither a decimal point nor an exponent is initially presumed to be type
integer
if its value fits in typeinteger
(32 bits); otherwise it is presumed to be typebigint
if its value fits in typebigint
(64 bits); otherwise it is taken to be typenumeric
. Constants that contain decimal points and/or exponents are always initially presumed to be typenumeric
.
More explanation and links in this related answer:
Add explicit casts for the smallint
parameters or quote them.
CREATE OR REPLACE FUNCTION f_typetest(smallint)
RETURNS bool AS 'SELECT TRUE' LANGUAGE sql;
Incorrect call:
SELECT * FROM f_typetest(1);
Correct calls:
SELECT * FROM f_typetest('1');
SELECT * FROM f_typetest(smallint '1');
SELECT * FROM f_typetest(1::int2);
SELECT * FROM f_typetest('1'::int2);

Using file:///// just doesn't work if security settings are set to even a moderate level.
If you just want users to be able to download/view files* located on a network or share you can set up a Virtual Directory in IIS. On the Properties tab make sure the "A share located on another computer" is selected and the "Connect as..." is an account that can see the network location.
Link to the virtual directory from your webpage (e.g. http://yoursite/yourvirtualdir/) and this will open up a view of the directory in the web browser.
*You can allow write permissions on the virtual directory to allow users to add files but not tried it and assume network permissions would override this setting.
