Simply delete the maintenance.flag
file in root folder and then delete the files of cache folder and session folder inside var/
folder.
If you are doing a loading screen, just set the parameter to not keep it in activity stack. In your manifest.xml, where you define your activity do:
<activity android:name=".LoadingScreen" android:noHistory="true" ... />
And in your code there is no need to call .finish() anymore. Just do startActivity(i);
There is also no need to keep a instance of your current activity in a separate field. You can always access it like LoadingScreen.this.doSomething()
instead of private LoadingScreen loadingScreen;
The fastest way to copy a database is to detach-copy-attach method, but the production users will not have database access while the prod db is detached. You can do something like this if your production DB is for example a Point of Sale system that nobody uses during the night.
If you cannot detach the production db you should use backup and restore.
You will have to create the logins if they are not in the new instance. I do not recommend you to copy the system databases.
You can use the SQL Server Management Studio to create the scripts that create the logins you need. Right click on the login you need to create and select Script Login As / Create.
This will lists the orphaned users:
EXEC sp_change_users_login 'Report'
If you already have a login id and password for this user, fix it by doing:
EXEC sp_change_users_login 'Auto_Fix', 'user'
If you want to create a new login id and password for this user, fix it by doing:
EXEC sp_change_users_login 'Auto_Fix', 'user', 'login', 'password'
Keep the Screen On
First way:
getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);
Second way:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:keepScreenOn="true">
...
</RelativeLayout>
Keep the CPU On:
<uses-permission android:name="android.permission.WAKE_LOCK" />
and
PowerManager powerManager = (PowerManager) getSystemService(POWER_SERVICE);
WakeLock wakeLock = powerManager.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK, "MyWakelockTag");
wakeLock.acquire();
To release the wake lock, call wakelock.release()
. This releases your claim to the CPU. It's important to release a wake lock as soon as your app is finished using it to avoid draining the battery.

When all else fails, try git apply
's --3way
option.
git apply --3way patchFile.patch
--3way
When the patch does not apply cleanly, fall back on 3-way merge if the patch records the identity of blobs it is supposed to apply to, and we have those blobs available locally, possibly leaving the conflict markers in the files in the working tree for the user to resolve. This option implies the --index option, and is incompatible with the --reject and the --cached options.
Typical fail case applies as much of the patch as it can, and leaves you with conflicts to work out in git however you normally do so. Probably one step easier than the reject
alternative.
To do this you pass a callback as a property down to the child from the parent.
For example:
var Parent = React.createClass({
getInitialState: function() {
return {
value: 'foo'
}
},
changeHandler: function(value) {
this.setState({
value: value
});
},
render: function() {
return (
<div>
<Child value={this.state.value} onChange={this.changeHandler} />
<span>{this.state.value}</span>
</div>
);
}
});
var Child = React.createClass({
propTypes: {
value: React.PropTypes.string,
onChange: React.PropTypes.func
},
getDefaultProps: function() {
return {
value: ''
};
},
changeHandler: function(e) {
if (typeof this.props.onChange === 'function') {
this.props.onChange(e.target.value);
}
},
render: function() {
return (
<input type="text" value={this.props.value} onChange={this.changeHandler} />
);
}
});
In the above example, Parent
calls Child
with a property of value
and onChange
. The Child
in return binds an onChange
handler to a standard <input />
element and passes the value up to the Parent
's callback if it's defined.
As a result the Parent
's changeHandler
method is called with the first argument being the string value from the <input />
field in the Child
. The result is that the Parent
's state can be updated with that value, causing the parent's <span />
element to update with the new value as you type it in the Child
's input field.
Default value for parameters are evaluated at "compilation", once. So obviously you can't access self
. The classic example is list
as default parameter. If you add elements into it, the default value for the parameter changes!
The workaround is to use another default parameter, typically None
, and then check and update the variable.
For the sake of snippet of what the guys have explained above:
import socket
from contextlib import closing
def find_free_port():
with closing(socket.socket(socket.AF_INET, socket.SOCK_STREAM)) as s:
s.bind(('', 0))
s.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)
return s.getsockname()[1]
If you use the Eclipse "New Android Project" wizard in a recent ADT bundle, you'll automatically get tabs implemented as a Fragments. This makes the conversion of your application to the tablet format much easier in the future.
For simple single screen layouts you may still use Activity
.
Make an images folder inside src(/src/images) And keep your image in it. Then import this image in your component(use your relative path). Like below-
import imageSrc from './images/image-name.jpg';
And then in your component.
<img title="my-img" src={imageSrc} alt="my-img" />
Another way is to keep images in public folder and import them using relative path. For this make an image folder in public folder and keep your image in it. And then in your component use it like below.
<img title="my-img" src='/images/my-image.jpg' alt="my-img" />
Both method work but first one is recommended because its cleaner way and images are handled by webpack during build time.
Your method doesn't have any callbacks so there is no reason to use .CallBack()
. You can simply return a Task with the desired values using .Returns()
and Task.FromResult, e.g.:
MyType someValue=...;
mock.Setup(arg=>arg.DoSomethingAsync())
.Returns(Task.FromResult(someValue));
Update 2014-06-22
Moq 4.2 has two new extension methods to assist with this.
mock.Setup(arg=>arg.DoSomethingAsync())
.ReturnsAsync(someValue);
mock.Setup(arg=>arg.DoSomethingAsync())
.ThrowsAsync(new InvalidOperationException());
Update 2016-05-05
As Seth Flowers mentions in the other answer, ReturnsAsync
is only available for methods that return a Task<T>
. For methods that return only a Task,
.Returns(Task.FromResult(default(object)))
can be used.
As shown in this answer, in .NET 4.6 this is simplified to .Returns(Task.CompletedTask);
, e.g.:
mock.Setup(arg=>arg.DoSomethingAsync())
.Returns(Task.CompletedTask);
The answers provided above are absolutely correct and worth to read but I just wanted to give a straight forward answer to the question.
The question asked is just a type conversion question and here its conversion from int
data type to float
data type and for that you can do it by the function :
float()
And for more details you can visit this page.
this is a simple code I just wrote to solve this, without removing the header row (first one).
var Tbl = document.getElementById('tblId');
while(Tbl.childNodes.length>2){Tbl.removeChild(Tbl.lastChild);}
Hope it works for you!!.

"most convenient block of data" probably refers to the width (in bits) of the WORD, in correspondance to the system bus width, or whatever underlying "bandwidth" is available. On a 16 bit system, with WORD being defined as 16 bits wide, moving data around in chunks the size of a WORD will be the most efficient way. (On hardware or "system" level.)
With Java being more or less platform independant, it just defines a "WORD" as the next size from a "BYTE", meaning "full bandwidth". I guess any platform that's able to run Java will use 32 bits for a WORD.
You should enable the Server authentication mode to mixed mode as following: In SQL Studio, select YourServer -> Property -> Security -> Select SqlServer and Window Authentication mode.
As of Spring Boot 2.3 and later, there's a built-in graceful shutdown mechanism.
Pre-Spring Boot 2.3, there is no out-of-the box graceful shutdown mechanism. Some spring-boot starters provide this functionality:
I am the author of nr. 1. The starter is named "Hiatus for Spring Boot". It works on the load balancer level, i.e. simply marks the service as OUT_OF_SERVICE, not interfering with application context in any way. This allows to do a graceful shutdown and means that, if required, the service can be taken out of service for some time and then brought back to life. The downside is that it doesn't stop the JVM, you will have to do it with kill
command. As I run everything in containers, this was no big deal for me, because I will have to stop and remove the container anyway.
Nos. 2 and 3 are more or less based on this post by Andy Wilkinson. They work one-way - once triggered, they eventually close the context.
Unfortunately the examples above didn't work for me in Chrome.
I came up with the below solution where you can specify the max height in PXs of each page. This will then splits the table into separate tables when the rows equal that height.
$(document).ready(function(){
var MaxHeight = 200;
var RunningHeight = 0;
var PageNo = 1;
$('table.splitForPrint>tbody>tr').each(function () {
if (RunningHeight + $(this).height() > MaxHeight) {
RunningHeight = 0;
PageNo += 1;
}
RunningHeight += $(this).height();
$(this).attr("data-page-no", PageNo);
});
for(i = 1; i <= PageNo; i++){
$('table.splitForPrint').parent().append("<div class='tablePage'><hr /><table id='Table" + i + "'><tbody></tbody></table><hr /></div>");
var rows = $('table tr[data-page-no="' + i + '"]');
$('#Table' + i).find("tbody").append(rows);
}
$('table.splitForPrint').remove();
});
You will also need the below in your stylesheet
div.tablePage {
page-break-inside:avoid; page-break-after:always;
}
Also try if in the eclipse paths there is some duplicated
Luna - http://download.eclipse.org/releases/luna
Luna - http://download.eclipse.org/releases/luna/1234567...
Try both of them, one may work.
In my case, with 2 eclispes installed, in one of them the path
Luna - http://download.eclipse.org/releases/luna
works, in the other one, i must select:
Luna - http://download.eclipse.org/releases/luna/123456...
In both the internal browser can access to internet. Both are Luna (but one is RCM, the other one i don't remember).
An alternative to get youtube channel ID by channel url without API:
function get_youtube_channel_ID($url){
$html = file_get_contents($url);
preg_match("'<meta itemprop=\"channelId\" content=\"(.*?)\"'si", $html, $match);
if($match && $match[1])
return $match[1];
}
In newer versions of VSCode this moved to a folder-specific configuration block.
Then add a "files.exclude" block, listing the directory globs you would like to exclude:
{
"files.exclude": {
"**/bin": true,
"**/obj": true
},
}
Excellent solution! I noticed when I tried to implement it that if I returned a value in the success clause, it came back as undefined. I had to store it in a variable and return that variable. This is the method I came up with:
function getWhatever() {
// strUrl is whatever URL you need to call
var strUrl = "", strReturn = "";
jQuery.ajax({
url: strUrl,
success: function(html) {
strReturn = html;
},
async:false
});
return strReturn;
}
What seems to be needed is to actually define the button as a button widget.
I had the same problem (in beta 1)
I did
$("#submitButton").button();
in my window ready handler, after that it worked to do as it is said in the docs, i.e.:
$("#submitButton").button('disable');
I guess this has to do with that jqm is converting the markup, but isnt actually instatiating a real button widget for buttons and link buttons.
You can do it using a table, but it is not pure CSS.

Note that it doesn't display exactly like you want, because it switches line on each option. However, I hope that this helps you come closer to the answer.
In a nutshell, three easy rules to remember PECS:
<? extends T>
wildcard if you need to retrieve object of
type T
from a collection.<? super T>
wildcard if you need to put objects of type T
in
a collection.>>> some_string='A,B,C,D,E'
>>> new_tuple= tuple(some_string.split(','))
>>> new_tuple
('A', 'B', 'C', 'D', 'E')
Appache commons IO various
FilenameUtils.wildcardMatch
See Apache javadoc here. It matches the wildcard with the filename. So you can use this method for your comparisons.
You cannot (and should not be able to) project onto a mapped entity. You can, however, project onto an anonymous type or onto a DTO:
public class ProductDTO
{
public string Name { get; set; }
// Other field you may need from the Product entity
}
And your method will return a List of DTO's.
public List<ProductDTO> GetProducts(int categoryID)
{
return (from p in db.Products
where p.CategoryID == categoryID
select new ProductDTO { Name = p.Name }).ToList();
}
I compile Kotlin to byte code and then de-compile that to Java. I compile with the Kotlin compiler and de-compile with cfr.
My project is here.
This allows me to compile this:
package functionsiiiandiiilambdas.functions.p01tailiiirecursive
tailrec fun findFixPoint(x: Double = 1.0): Double =
if (x == Math.cos(x)) x else findFixPoint(Math.cos(x))
To this:
package functionsiiiandiiilambdas.functions.p01tailiiirecursive;
public final class ExampleKt {
public static final double findFixPoint(double x) {
while (x != Math.cos(x)) {
x = Math.cos(x);
}
return x;
}
public static /* bridge */ /* synthetic */ double findFixPoint$default(
double d, int n, Object object) {
if ((n & 1) != 0) {
d = 1.0;
}
return ExampleKt.findFixPoint(d);
}
}
I searched for hours, and I tried almost everything suggested.
This worked for almost every entity :
$input = "ažškunrukiš ? àéò ??? ©€ ?? ? ?? ? R?";
echo htmlentities($input, ENT_HTML5 , 'UTF-8');
result :

I'm one of the noob too when I encountered something like this. So... I set the passwords using the command security page gave me: /opt/lampp/lampp security Then I used password xyz for all the passwords... Then when I go to site/, it ask for a basic authentication. But when I tried root//xyz, it does not allow me login. So, after some digging, it turns out the xyz password was set for a default user named 'lampp'. When I tried to login using lampp//xyz, it worked like a charm.
The issue is that they made an assumption that everyone knows to use lampp//rootpw as their login o.O And... that is a basic auth for the directory! not pw for phpmyadmin or pw for mysql...
I try GET 'http://example.com/?var=value'
Important use '

Sorry for my English
There is often the tip to use 'echo.'
But that is slow, and it could fail with an error message, as cmd.exe will search first for a file named 'echo' (without extension) and only when the file doesn't exists it outputs an empty line.
You could use echo(
. This is approximately 20 times faster, and it works always. The only drawback could be that it looks odd.
More about the different ECHO:/\
variants is at DOS tips: ECHO. FAILS to give text or blank line.
You can use a function that accepts a array and finds the max value in it. i made it generic so it could also accept other data types
public static <T extends Comparable<T>> T findMax(T[] array){
T max = array[0];
for(T data: array){
if(data.compareTo(max)>0)
max =data;
}
return max;
}
In most of the answers , recommended way to install nvm is to use Homebrew
Do not do that
At Github Page for nvm it is clearly called out:
Homebrew installation is not supported. If you have issues with homebrew-installed nvm, please brew uninstall it, and install it using the instructions below, before filing an issue.
Use the following method instead
curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.33.11/install.sh | bash
The script clones the nvm repository to ~/.nvm and adds the source line to your profile (~/.bash_profile, ~/.zshrc, ~/.profile, or ~/.bashrc).
And then use nvm to install node. For example to install latest LTS version do:
nvm install v8.11.1
Clean and hassle free. It would mark this as your default node version as well so you should be all set
for me that code working fine. (IE10+)

standby="Loading áudio..." style="width: 100%; height: 170px" id="MediaPlayer">...
Hope this help.
The best way is to use an And

To learn what row was selected, add a ListSelectionListener
, as shown in How to Use Tables in the example SimpleTableSelectionDemo
. A JList
can be constructed directly from the linked list's toArray()
method, and you can add a suitable listener to it for details.
From your example, it seems to me you want to use a static method.
class mystuff:
@staticmethod
def average(a,b,c): #get the average of three numbers
result=a+b+c
result=result/3
return result
print mystuff.average(9,18,27)
Please note that an heavy usage of static methods in python is usually a symptom of some bad smell - if you really need functions, then declare them directly on module level.
PCDATA
is text that will be parsed by a parser. Tags inside the text
will be treated as markup and entities will be expanded. CDATA
is text that will not be parsed by a parser. Tags inside the text will
not be treated as markup and entities will not be expanded.By default, everything is PCDATA
. In the following example, ignoring the root, <bar>
will be parsed, and it'll have no content, but one child.
<?xml version="1.0"?>
<foo>
<bar><test>content!</test></bar>
</foo>
When we want to specify that an element will only contain text, and no child elements, we use the keyword PCDATA
, because this keyword specifies that the element must contain parsable character data – that is , any text except the characters less-than (<
) , greater-than (>
) , ampersand (&
), quote('
) and double quote ("
).
In the next example, <bar>
contains CDATA
. Its content will not be parsed and is thus <test>content!</test>
.
<?xml version="1.0"?>
<foo>
<bar><![CDATA[<test>content!</test>]]></bar>
</foo>
There are several content models in SGML. The #PCDATA
content model says that an element may contain plain text. The "parsed" part of it means that markup (including PIs, comments and SGML directives) in it is parsed instead of displayed as raw text. It also means that entity references are replaced.
Another type of content model allowing plain text contents is CDATA
. In XML, the element content model may not implicitly be set to CDATA
, but in SGML, it means that markup and entity references are ignored in the contents of the element. In attributes of CDATA
type however, entity references are replaced.
In XML, #PCDATA
is the only plain text content model. You use it if you at all want to allow text contents in the element. The CDATA
content model may be used explicitly through the CDATA
block markup in #PCDATA
, but element contents may not be defined as CDATA
per default.
In a DTD, the type of an attribute that contains text must be CDATA
. The CDATA
keyword in an attribute declaration has a different meaning than the CDATA
section in an XML document. In a CDATA
section all characters are legal (including <
,>
,&
,'
and "
characters), except the ]]>
end tag.
#PCDATA
is not appropriate for the type of an attribute. It is used for the type of "leaf" text.
#PCDATA
is prepended by a hash in the content model to distinguish this keyword from an element named PCDATA
(which would be perfectly legal).
In Spyder one can configure the IPython console for each Python file to clear all variables before each execution in the Menu Run -> Configuration -> General settings -> Remove all variables before execution
.
I have set the vm argument in WAS server as -Dfile.encoding=UTF-8 to change the servers' default character set.
This will do
foreach($results['data'] as $result) {
echo $result['type'], '<br>';
}
<input [ngModel]="item.value | currency" (ngModelChange)="item.value=$event"
name="name" type="text" />
I would like to add one more point to the accepted answer.
If the type of your input control is not text the pipe will not work.
Keep it in mind and save your time.
This answer is correct for old versions of iOS, but is now obsolete. You should use Micky Duncan's answer, which covers custom containers.
Don't do this! The intent of the UIViewController
is to drive the entire screen. It just isn't appropriate for this, and it doesn't really add anything you need.
All you need is an object that owns your custom view. Just use a subclass of UIView
itself, so it can be added to your window hierarchy and the memory management is fully automatic.
Point the subview NIB's owner a custom subclass of UIView
. Add a contentView
outlet to this custom subclass, and point it at the view within the nib. In the custom subclass do something like this:
- (id)initWithFrame: (CGRect)inFrame;
{
if ( (self = [super initWithFrame: inFrame]) ) {
[[NSBundle mainBundle] loadNibNamed: @"NibNameHere"
owner: self
options: nil];
contentView.size = inFrame.size;
// do extra loading here
[self addSubview: contentView];
}
return self;
}
- (void)dealloc;
{
self.contentView = nil;
// additional release here
[super dealloc];
}
(I'm assuming here you're using initWithFrame:
to construct the subview.)
I implore everyone to use Mongoose's query builder language and promises instead of callbacks:
User.find().or([{ name: param }, { nickname: param }])
.then(users => { /*logic here*/ })
.catch(error => { /*error logic here*/ })
Read more about Mongoose Queries.

A straightforward solution would be [A-Za-z][A-Za-z]\d\d\d\d\d\d
or [A-Za-z]{2}\d{6}
.
If you want to accept only capital letters then replace [A-Za-z]
with [A-Z]
.
If we want to add custom HTTP headers to a POST request, we must pass them through a dictionary to the headers
parameter.
Here is an example with a non-empty body and headers:
import requests
import json
url = 'https://somedomain.com'
body = {'name': 'Maryja'}
headers = {'content-type': 'application/json'}
r = requests.post(url, data=json.dumps(body), headers=headers)
Padding is a way to add kind of a margin inside the Div.
Just Use
div { padding-left: 20px; }
And to mantain the size, you would have to -20px from the original width of the Div.
In my case, simply giving the user permissions on the database fixed it.
So Right click on the database -> Click Properties -> [left hand menu] Click Permissions -> and scroll down to Backup database -> Tick "Grant"
Daniel Farrell's Bootstrap Combobox does the job perfectly. Here's an example from his GitHub repository.

As an added bonus, I've included a placeholder in script since applying it to the markup does not hold.

To get the projects root directory within a Controller:
Create a property for the hosting environment
private readonly IHostingEnvironment _hostingEnvironment;
Add Microsoft.AspNetCore.Hosting to your controller
using Microsoft.AspNetCore.Hosting;
Register the service in the constructor
public HomeController(IHostingEnvironment hostingEnvironment) {
_hostingEnvironment = hostingEnvironment;
}
Now, to get the projects root path
string projectRootPath = _hostingEnvironment.ContentRootPath;
To get the "wwwroot" path, use
_hostingEnvironment.WebRootPath
You can do this with LibreOffice:
libreoffice --headless --convert-to csv $filename --outdir $outdir
For reasons not clear to me, you might need to run this with sudo. You can make LibreOffice work with sudo without requiring a password by adding this line to you sudoers file:
users ALL=(ALL) NOPASSWD: libreoffice
<input type="text" value="3" class="field left" readonly>
You could see in https://www.w3schools.com/tags/att_input_readonly.asp
The method to set "readonly":
$("input").attr("readonly", true)
to cancel "readonly"(work in jQuery):
$("input").attr("readonly", false)
input[type='checkbox', name='ProductCode']
That's the CSS way and I'm almost sure it will work in jQuery.
MongoDB needs data directory to store data.
Default path is /data/db
When you start MongoDB engine, it searches this directory which is missing in your case. Solution is create this directory and assign rwx

If you want to change the path of your data directory then you should specify it while starting mongod server like,
mongod --dbpath /data/<path> --port <port no>
This should help you start your mongod server with custom path and port.

Use Enumerable.Contains function:
var result =
!(compareString.Contains(firstString) || compareString.Contains(secondString));
I don't know if this still is an issue, but i prefere just to use the My.Settings in my code.
Visual Studio generates a simple class with functions for reading settings from the app.config file.
You can simply access it using My.Settings.ConnectionString.
Using Context As New Data.Context.DataClasses()
Context.Connection.ConnectionString = My.Settings.ConnectionString
End Using
It cannot be done - AFAIK.
However you may use for example jquery (although you can do it with plain javascript) to serialize the form and send (using AJAX) while adding your custom header.
Look at the jquery serialize
which changes an HTML FORM into form-url-encoded
values ready for POST.
My suggestion is to include either
If you have two values yanked into two different registers (for example register a
and register b
) then you can simply set a variable c
and do the operation on it.
For example, :set c = str2float(@a) + str2float(@b)
and then you can paste the content of c
anywhere.
For example whilst in INSERT mode, CTRL + R
then type =
to enter into the expression register and just type c
after equal sign and hit ENTER. Done you should now have the total of a
and b
registers.
All these can be recorded in a macro and repeated over!
The str2float
function is used if you are working with floats, if you don't, you will get integers instead.
I am not sure if this is idiomatic but it worked for my case where I needed to add 2 numbers in a row and repeat it for 500 more lines.
You can use anonymous types for example:
var empData = from res in _db.EMPLOYEEs
where res.EMAIL == givenInfo || res.USER_NAME == givenInfo
select new { res.EMAIL, res.USER_NAME };
A free and easy to use service is provided at Webtechriser (click here to read the article) (called wipmania). This one is a JSONP service and requires plain javascript coding with HTML.

As of Android Studio 1.1, we've got official (experimental) support for writing Unit Tests (Roboelectric works as well).
Source: https://sites.google.com/a/android.com/tools/tech-docs/unit-testing-support
You might consider wrapping the operations. For example:
class Utils
{
public static double divide(int num, int denom) {
return ((double) num) / denom;
}
}
This allows you to look up (just once) whether the cast does exactly what you want. This method could also be subject to tests, to ensure that it continues to do what you want. It also doesn't matter what trick you use to cause the division (you could use any of the answers here), as long as it results in the correct result. Anywhere you need to divide two integers, you can now just call Utils::divide
and trust that it does the right thing.
be aware that this is dangerous:
WHERE `column` LIKE '%{$needle}%'
do first:
$needle = mysql_real_escape_string($needle);
so it will prevent possible attacks.
http://api.jquery.com/on/ states:
When jQuery calls a handler, the
this
keyword is a reference to the element where the event is being delivered; for directly bound eventsthis
is the element where the event was attached and for delegated eventsthis
is an element matching selector. (Note thatthis
may not be equal toevent.target
if the event has bubbled from a descendant element.)To create a jQuery object from the element so that it can be used with jQuery methods, use $( this ).
If we have
<input type="button" class="btn" value ="btn1">
<input type="button" class="btn" value ="btn2">
<input type="button" class="btn" value ="btn3">
<div id="outer">
<input type="button" value ="OuterB" id ="OuterB">
<div id="inner">
<input type="button" class="btn" value ="InnerB" id ="InnerB">
</div>
</div>
Check the below output:
<script>
$(function(){
$(".btn").on("click",function(event){
console.log($(this));
console.log($(event.currentTarget));
console.log($(event.target));
});
$("#outer").on("click",function(event){
console.log($(this));
console.log($(event.currentTarget));
console.log($(event.target));
})
})
</script>
Note that I use $
to wrap the dom element in order to create a jQuery object, which is how we always do.
You would find that for the first case, this
,event.currentTarget
,event.target
are all referenced to the same element.
While in the second case, when the event delegate to some wrapped element are triggered, event.target
would be referenced to the triggered element, while this
and event.currentTarget
are referenced to where the event is delivered.
For this
and event.currentTarget
, they are exactly the same thing according to http://api.jquery.com/event.currenttarget/

In fact, you can't change the time once it's created. But you can create it easily with many constructors: https://docs.microsoft.com/en-us/dotnet/api/system.datetime.-ctor?view=netframework-4.7.2
For example, if you want to create a DateTime changing Seconds, you can just do this:
DateTime now = DateTime.Now;
DateTime secondschanged = new DateTime(now.Year, now.Month, now.Day, now.Hour, now.Minute, yourseconds);
In my strange case, Intellij remembers forever about my project even if I delete .iml
... Thus I did the following:
.iml
file.my_proj
) to my_proj_backup
.my_proj_backup
in Intellij and close.my_proj
, and open it in Intellij. Then close it.my_proj
and move my_proj_backup
back to my_proj
. Then open my_proj
in Intellij.Then it happily forgot the old my_proj
:)
I had the same problem in Windows. I solved it adding: include mime.types; under http{ in my nginx.conf file. Then it still didn't work.. so I looked at the error.log file and I noticed it was trying to charge the .css and javascript files from the file path but with an /http folder between. Ex: my .css was in : "C:\Users\pc\Documents\nginx-server/player-web/css/index.css" and it was taking it from: "C:\Users\pc\Documents\nginx-server/html/player-web/css/index.css" So i changed my player-web folder inside an html folder and it worked ;)
For more solution i have completed the solution of (the great) Tiago Gouvêa exposed before only for strings and arrays
i used md_convert_encoding() function instead of utf8_encode(), it works for me : (12 hours loosed ...)
// this object return me a big array who have multiple arrays imbricated
$get_days = program::get_days($ARR, $client);
// and i use this function for well parsing what the server return *
function convert_to_utf8_recursively($dat){
if( is_string($dat) ){
return mb_convert_encoding($dat, 'UTF-8', 'UTF-8');
}
elseif( is_array($dat) ){
$ret = [];
foreach($dat as $i => $d){
$ret[$i] = convert_to_utf8_recursively($d);
}
return $ret;
}
else{
return $dat;
}
}
// use
$data = convert_to_utf8_recursively($get_days);
"1,2,3,4".split(",")
as strings
"1,2,3,4".split(",").map { |s| s.to_i }
as integers
I generally try to keep all of my packages in one library, but if you want to add a library why not append the new library (which must already exist in your filesystem) to the existing library path?
.libPaths( c( .libPaths(), "~/userLibrary") )
# obviously this would need to be a valid file directory in your OS
# min just happened to be on a Mac that day
Or (and this will make the userLibrary the first place to put new packages):
.libPaths( c( "~/userLibrary" , .libPaths() ) )
Then I get (at least back when I wrote this originally):
> .libPaths()
[1] "/Library/Frameworks/R.framework/Versions/2.15/Resources/library"
[2] "/Users/user_name/userLibrary"
The .libPaths
function is a bit different than most other nongraphics functions. It works via side-effect. The functions Sys.getenv
and Sys.setenv
that report and alter the R environment variables have been split apart but .libPaths
can either report or alter its target.
The information about the R startup process can be read at ?Startup
help page and there is RStudio material at: https://support.rstudio.com/hc/en-us/articles/200549016-Customizing-RStudio
In your case it appears that RStudio is not respecting the Rprofile.site settings or perhaps is overriding them by reading an .Rprofile setting from one of the RStudio defaults. It should also be mentioned that the result from this operation also appends the contents of calls to .Library
and .Library.site
, which is further reason why an RStudio- (or any other IDE or network installed-) hosted R might exhibit different behavior.
Since Sys.getenv()
returns the current system environment for the R process, you can see the library and other paths with:
Sys.getenv()[ grep("LIB|PATH", names(Sys.getenv())) ]
The two that matter for storing and accessing packages are (now different on a Linux box):
R_LIBS_SITE /usr/local/lib/R/site-library:/usr/lib/R/site-library:/usr/lib/R/library
R_LIBS_USER /home/david/R/x86_64-pc-linux-gnu-library/3.5.1/

The difference is between Rails’ html_safe()
and raw()
. There is an excellent post by Yehuda Katz on this, and it really boils down to this:
def raw(stringish)
stringish.to_s.html_safe
end
Yes, raw()
is a wrapper around html_safe()
that forces the input to String and then calls html_safe()
on it. It’s also the case that raw()
is a helper in a module whereas html_safe()
is a method on the String class which makes a new ActiveSupport::SafeBuffer instance — that has a @dirty
flag in it.
Refer to "Rails’ html_safe vs. raw".
Web APi 2 and later versions support a new type of routing, called attribute routing. As the name implies, attribute routing uses attributes to define routes. Attribute routing gives you more control over the URIs in your web API. For example, you can easily create URIs that describe hierarchies of resources.
For example:
[Route("customers/{customerId}/orders")]
public IEnumerable<Order> GetOrdersByCustomer(int customerId) { ... }
Will perfect and you don't need any extra code for example in WebApiConfig.cs. Just you have to be sure web api routing is enabled or not in WebApiConfig.cs , if not you can activate like below:
// Web API routes
config.MapHttpAttributeRoutes();
You don't have to do something more or change something in WebApiConfig.cs. For more details you can have a look this article.
To elaborate on @serine's answer and illustrate working with non-trivial multi-valued condition: I had a need to show a "dim-out" overlay on an item for the boolean condition NOT a AND (b OR NOT c)
.
For background, this is a "Multiple Choice" question. If the user picks a wrong answer it becomes disabled (dimmed out and cannot be selected again). An automated agent has the ability to focus on any particular choice to give an explanation (border highlighted). When the agent focuses on an item, it should not be dimmed out even if it is disabled. All items that are not in focused are marked de-focused, and should be dimmed out.
The logic for dimming is thus:
NOT IsFocused AND (IsDefocused OR NOT Enabled)
To implement this logic, I made a generic IMultiValueConverter
named (awkwardly) to match my logic
// 'P' represents a parenthesis
// ! a && ( b || ! c )
class NOT_a_AND_P_b_OR_NOT_c_P : IMultiValueConverter
{
// redacted [...] for brevity
public object Convert(object[] values, ...)
{
bool a = System.Convert.ToBoolean(values[0]);
bool b = System.Convert.ToBoolean(values[1]);
bool c = System.Convert.ToBoolean(values[2]);
return !a && (b || !c);
}
...
}
In the XAML I use this in a MultiDataTrigger
in a <Style><Style.Triggers>
resource
<MultiDataTrigger>
<MultiDataTrigger.Conditions>
<!-- when the equation is TRUE ... -->
<Condition Value="True">
<Condition.Binding>
<MultiBinding Converter="{StaticResource NOT_a_AND_P_b_OR_NOT_c_P}">
<!-- NOT IsFocus AND ( IsDefocused OR NOT Enabled ) -->
<Binding Path="IsFocus"/>
<Binding Path="IsDefocused" />
<Binding Path="Enabled" />
</MultiBinding>
</Condition.Binding>
</Condition>
</MultiDataTrigger.Conditions>
<MultiDataTrigger.Setters>
<!-- ... show the 'dim-out' overlay -->
<Setter Property="Visibility" Value="Visible" />
</MultiDataTrigger.Setters>
</MultiDataTrigger>
And for completeness sake, my converter is defined in a ResourceDictionary
<ResourceDictionary xmlns:conv="clr-namespace:My.Converters" ...>
<conv:NOT_a_AND_P_b_OR_NOT_c_P x:Key="NOT_a_AND_P_b_OR_NOT_c_P" />
</ResourceDictionary>

Never and ever for the sake of your own good, name the folders or files with symbols like "-" or "_". If you did so, you may face few issues. like mine, say, though your command for importing is correct, you wont be able to successfully import the desired files which are available inside such named folders.

Tried many searches and viewed many stackoverflow questions and unable to decide what went wrong. I cross checked my files multiple times, i used __init__.py

And after a long long long time, i figured this out while talking with a friend of mine. I am little stupid to use such naming conventions. I should never use space or special symbols to define a name for any folder or file. So, this is what I wanted to convey. Have a good day!

If your code must run under Python2 and Python3, use the 2to3 six library like this:
import six
six.next(g) # on PY2K: 'g.next()' and onPY3K: 'next(g)'
Here is the list of commands you have to run while the emulator is running, I test this solution for an avd on Android 2.2 :
adb shell mount -o rw,remount -t yaffs2 /dev/block/mtdblock03 /system
adb push su /system/xbin/su
adb shell chmod 06755 /system
adb shell chmod 06755 /system/xbin/su
It assumes that the su binary is located in the working directory. You can find su and superuser here : http://forum.xda-developers.com/showthread.php?t=682828. You need to run these commands each time you launch the emulator. You can write a script that launch the emulator and root it.

date
can give you the difference and format it for you (OS X options shown)
date -ujf%s $(($(date -jf%T "10:36:10" +%s) - $(date -jf%T "10:33:56" +%s))) +%T
# 00:02:14
date -ujf%s $(($(date -jf%T "10:36:10" +%s) - $(date -jf%T "10:33:56" +%s))) \
+'%-Hh %-Mm %-Ss'
# 0h 2m 14s
Some string processing can remove those empty values
date -ujf%s $(($(date -jf%T "10:36:10" +%s) - $(date -jf%T "10:33:56" +%s))) \
+'%-Hh %-Mm %-Ss' | sed "s/[[:<:]]0[hms] *//g"
# 2m 14s
This won't work if you place the earlier time first. If you need to handle that, change $(($(date ...) - $(date ...)))
to $(echo $(date ...) - $(date ...) | bc | tr -d -)

You can use the sp_MSforeachtable stored procedure like so:
USE MyDatabase
EXEC sp_MSforeachtable 'TRUNCATE TABLE ?'
Be warned that this will delete (by truncation) ALL data from all user tables. And in case you can't TRUNCATE due to foreign keys etc. you can run the same as a delete:
USE MyDatabase
EXEC sp_MSforeachtable 'DELETE FROM ?'
As said before, @Column(unique = true)
is a shortcut to UniqueConstraint
when it is only a single field.
From the example you gave, there is a huge difference between both.
@Column(unique = true)
@ManyToOne(optional = false, fetch = FetchType.EAGER)
private ProductSerialMask mask;
@Column(unique = true)
@ManyToOne(optional = false, fetch = FetchType.EAGER)
private Group group;
This code implies that both mask
and group
have to be unique, but separately. That means that if, for example, you have a record with a mask.id = 1 and tries to insert another record with mask.id = 1, you'll get an error, because that column should have unique values. The same aplies for group.
On the other hand,
@Table(
name = "product_serial_group_mask",
uniqueConstraints = {@UniqueConstraint(columnNames = {"mask", "group"})}
)
Implies that the values of mask + group combined should be unique. That means you can have, for example, a record with mask.id = 1 and group.id = 1, and if you try to insert another record with mask.id = 1 and group.id = 2, it'll be inserted successfully, whereas in the first case it wouldn't.
If you'd like to have both mask and group to be unique separately and to that at class level, you'd have to write the code as following:
@Table(
name = "product_serial_group_mask",
uniqueConstraints = {
@UniqueConstraint(columnNames = "mask"),
@UniqueConstraint(columnNames = "group")
}
)
This has the same effect as the first code block.
first of all,
be sure that there is a post
if(isset($_POST['username'])) {
// check if the username has been set
}
second, and most importantly, sanitize the data, meaning that
$query = "SELECT password FROM users WHERE username='".$_POST['username']."'";
is deadly dangerous, instead use
$query = "SELECT password FROM users WHERE username='".mysql_real_escape_string($_POST['username'])."'";
and please research the subject sql injection
A self-explanatory simple one-liner to extract token for kubernetes dashboard login.

Copy the token and paste it on the kubernetes dashboard under token sign in option and you are good to use kubernetes dashboard
you can use a string formatter to pad any integer with zeros. It acts just like C's printf
.
>>> d = datetime.date.today()
>>> '%02d' % d.month
'03'
Updated for py36: Use f-strings! For general int
s you can use the d
formatter and explicitly tell it to pad with zeros:
>>> d = datetime.date.today()
>>> f"{d.month:02d}"
'07'
But datetime
s are special and come with special formatters that are already zero padded:
>>> f"{d:%d}" # the day
'01'
>>> f"{d:%m}" # the month
'07'

It denotes an rvalue reference. Rvalue references will only bind to temporary objects, unless explicitly generated otherwise. They are used to make objects much more efficient under certain circumstances, and to provide a facility known as perfect forwarding, which greatly simplifies template code.
In C++03, you can't distinguish between a copy of a non-mutable lvalue and an rvalue.
std::string s;
std::string another(s); // calls std::string(const std::string&);
std::string more(std::string(s)); // calls std::string(const std::string&);
In C++0x, this is not the case.
std::string s;
std::string another(s); // calls std::string(const std::string&);
std::string more(std::string(s)); // calls std::string(std::string&&);
Consider the implementation behind these constructors. In the first case, the string has to perform a copy to retain value semantics, which involves a new heap allocation. However, in the second case, we know in advance that the object which was passed in to our constructor is immediately due for destruction, and it doesn't have to remain untouched. We can effectively just swap the internal pointers and not perform any copying at all in this scenario, which is substantially more efficient. Move semantics benefit any class which has expensive or prohibited copying of internally referenced resources. Consider the case of std::unique_ptr
- now that our class can distinguish between temporaries and non-temporaries, we can make the move semantics work correctly so that the unique_ptr
cannot be copied but can be moved, which means that std::unique_ptr
can be legally stored in Standard containers, sorted, etc, whereas C++03's std::auto_ptr
cannot.
Now we consider the other use of rvalue references- perfect forwarding. Consider the question of binding a reference to a reference.
std::string s;
std::string& ref = s;
(std::string&)& anotherref = ref; // usually expressed via template
Can't recall what C++03 says about this, but in C++0x, the resultant type when dealing with rvalue references is critical. An rvalue reference to a type T, where T is a reference type, becomes a reference of type T.
(std::string&)&& ref // ref is std::string&
(const std::string&)&& ref // ref is const std::string&
(std::string&&)&& ref // ref is std::string&&
(const std::string&&)&& ref // ref is const std::string&&
Consider the simplest template function- min and max. In C++03 you have to overload for all four combinations of const and non-const manually. In C++0x it's just one overload. Combined with variadic templates, this enables perfect forwarding.
template<typename A, typename B> auto min(A&& aref, B&& bref) {
// for example, if you pass a const std::string& as first argument,
// then A becomes const std::string& and by extension, aref becomes
// const std::string&, completely maintaining it's type information.
if (std::forward<A>(aref) < std::forward<B>(bref))
return std::forward<A>(aref);
else
return std::forward<B>(bref);
}
I left off the return type deduction, because I can't recall how it's done offhand, but that min can accept any combination of lvalues, rvalues, const lvalues.
If you just want to get the path to a certain action, use UrlHelper
:
UrlHelper u = new UrlHelper(this.ControllerContext.RequestContext);
string url = u.Action("About", "Home", null);
if you want to create a hyperlink:
string link = HtmlHelper.GenerateLink(this.ControllerContext.RequestContext, System.Web.Routing.RouteTable.Routes, "My link", "Root", "About", "Home", null, null);
Intellisense will give you the meaning of each of the parameters.
Update from comments: controller already has a UrlHelper
:
string url = this.Url.Action("About", "Home", null);
Quite often the issue is a non-breaking space - CHAR(160)
- especially from Web text sources -that CLEAN
can't remove, so I would go a step further than this and try a formula like this which replaces any non-breaking spaces with a standard one
=TRIM(CLEAN(SUBSTITUTE(A1,CHAR(160)," ")))
Ron de Bruin has an excellent post on tips for cleaning data here
You can also remove the CHAR(160)
directly without a workaround formula by
ALT
and type 0160
using the numeric keypadYou can try define in your LINQ expression only the field's that you will need.
Example. Imagine that you have an Model with Id, Name, Phone and Picture (byte array) and need to load from json into an select list.
LINQ Query:
var listItems = (from u in Users where u.name.Contains(term) select u).ToList();
The problem here is "select u" that get all fields. So, if you have big pictures, booomm.
How to solve? very, very simple.
var listItems = (from u in Users where u.name.Contains(term) select new {u.Id, u.Name}).ToList();
The best practices is select only the field that you will use.
Remember. This is a simple tip, but can help many ASP.NET MVC developpers.

I know this is an old post, but most of the answers are not tail recursive i.e. they do some operations after returning from the recursive call, and hence not the most efficient.
Here is a tail recursive version:
public Node reverse(Node previous, Node current) {
if(previous == null)
return null;
if(previous.equals(head))
previous.setNext(null);
if(current == null) { // end of list
head = previous;
return head;
} else {
Node temp = current.getNext();
current.setNext(previous);
reverse(current, temp);
}
return null; //should never reach here.
}
Call with:
Node newHead = reverse(head, head.getNext());

The selected answer is the good one, but is long, so you might not read the key point:
I got an error with the SSL when accesign www.example.com but it worked fine if I go to example.com
If it happens the same to you, probably your error is that in the DNS configuration you have set:
CNAME www.example.com --> example.com (WRONG)
But, what you have to do is:
CNAME www.example.com --> username.github.io (GOOD)
or
CNAME www.example.com --> organization.github.io (GOOD)
That was my error
You cannot use properties that are not mapped to a database column in a Where
expression. You must build the expression based on mapped properties, like:
var date = DateTime.Now.AddYears(-from);
result = result.Where(p => date >= p.DOB);
// you don't need `AsQueryable()` here because result is an `IQueryable` anyway
As a replacement for your not mapped Age
property you can extract this expression into a static method like so:
public class clsProfileDate
{
// ...
public DateTime DOB { get; set; } // property mapped to DB table column
public static Expression<Func<clsProfileDate, bool>> IsOlderThan(int age)
{
var date = DateTime.Now.AddYears(-age);
return p => date >= p.DOB;
}
}
And then use it this way:
result = result.Where(clsProfileDate.IsOlderThan(from));
const getJsonIndented = (obj) => JSON.stringify(newObj, null, 4).replace(/["{[,\}\]]/g, "")
const JSONDisplayer = ({children}) => (
<div>
<pre>{getJsonIndented(children)}</pre>
</div>
)
Then you can easily use it:
const Demo = (props) => {
....
return <JSONDisplayer>{someObj}<JSONDisplayer>
}
You may want to use the Continue
statement to continue with the innermost loop.
Excerpt from PowerShell
help file:
In a script, the
continue
statement causes program flow to move immediately to the top of the innermost loop controlled by any of these statements:
for
foreach
while
A couple of "enhancements" I use for debugging, especially when running projects (ie not in debug mode).
Automatically copy the caller-name and message to the clipboard, because you can't search an image!
package forumposts;
import java.awt.Toolkit;
import java.awt.datatransfer.Clipboard;
import java.awt.datatransfer.StringSelection;
import javax.swing.JOptionPane;
public final class MsgBox
{
public static void info(String message) {
info(message, theNameOfTheMethodThatCalledMe());
}
public static void info(String message, String caller) {
show(message, caller, JOptionPane.INFORMATION_MESSAGE);
}
static void error(String message) {
error(message, theNameOfTheMethodThatCalledMe());
}
public static void error(String message, String caller) {
show(message, caller, JOptionPane.ERROR_MESSAGE);
}
public static void show(String message, String title, int iconId) {
setClipboard(title+":"+NEW_LINE+message);
JOptionPane.showMessageDialog(null, message, title, iconId);
}
private static final String NEW_LINE = System.lineSeparator();
public static String theNameOfTheMethodThatCalledMe() {
return Thread.currentThread().getStackTrace()[3].getMethodName();
}
public static void setClipboard(String message) {
CLIPBOARD.setContents(new StringSelection(message), null);
// nb: we don't respond to the "your content was splattered"
// event, so it's OK to pass a null owner.
}
private static final Toolkit AWT_TOOLKIT = Toolkit.getDefaultToolkit();
private static final Clipboard CLIPBOARD = AWT_TOOLKIT.getSystemClipboard();
}
The full class also has debug and warning methods, but I cut them for brevity and you get the main points anyway. You can use a public static boolean isDebugEnabled to suppress debug messages. If done properly the optimizer will (almost) remove these method calls from your production code. See: http://c2.com/cgi/wiki?ConditionalCompilationInJava
Cheers. Keith.
This will help you.

Easy steps to Integrate ckeditor with php pages
step 1 : download the ckeditor.zip file
step 2 : paste ckeditor.zip file on root directory of the site or you can paste it where the files are (i did this one )
step 3 : extract the ckeditor.zip file
step 4 : open the desired php page you want to integrate with here page1.php
step 5 : add some javascript first below, this is to call elements of ckeditor and styling and css without this you will only a blank textarea
<script type="text/javascript" src="ckeditor/ckeditor.js"></script>
And if you are using in other sites, then use relative links for that here is one below
<script type="text/javascript" src="somedirectory/ckeditor/ckeditor.js"></script>
step 6 : now!, you need to call the work code of ckeditor on your page page1.php below is how you call it
<?php
// Make sure you are using a correct path here.
include_once 'ckeditor/ckeditor.php';
$ckeditor = new CKEditor();
$ckeditor->basePath = '/ckeditor/';
$ckeditor->config['filebrowserBrowseUrl'] = '/ckfinder/ckfinder.html';
$ckeditor->config['filebrowserImageBrowseUrl'] = '/ckfinder/ckfinder.html?type=Images';
$ckeditor->config['filebrowserFlashBrowseUrl'] = '/ckfinder/ckfinder.html?type=Flash';
$ckeditor->config['filebrowserUploadUrl'] = '/ckfinder/core/connector/php/connector.php?command=QuickUpload&type=Files';
$ckeditor->config['filebrowserImageUploadUrl'] = '/ckfinder/core/connector/php/connector.php?command=QuickUpload&type=Images';
$ckeditor->config['filebrowserFlashUploadUrl'] = '/ckfinder/core/connector/php/connector.php?command=QuickUpload&type=Flash';
$ckeditor->editor('CKEditor1');
?>
step 7 : what ever you name you want, you can name to it ckeditor by changing the step 6 code last line
$ckeditor->editor('mycustomname');
step 8 : Open-up the page1.php, see it, use it, share it and Enjoy because we all love Open Source.
Thanks
In your test, you are comparing the two TestParent
beans, not the single TestedChild
bean.
Also, Spring proxies your @Configuration
class so that when you call one of the @Bean
annotated methods, it caches the result and always returns the same object on future calls.
See here:
I don't know how stubhub's api works, but generally it should look like this:
s = requests.Session()
data = {"login":"my_login", "password":"my_password"}
url = "http://example.net/login"
r = s.post(url, data=data)
Now your session contains cookies provided by login form. To access cookies of this session simply use
s.cookies
Any further actions like another requests will have this cookie
EditText edt=(EditText)findViewById(R.id.Edt);
String data=edt.getText().toString();
if(data=="" || data==null){
Log.e("edit text is null?","yes");
}
else {
Log.e("edit text is null?","no");
}
do like this for all five edit text
new_hash = old_hash.merge(old_hash) do |_key, value, _value|
value.upcase
end
# old_hash = {"a" => "b", "c" => "d"}
# new_hash = {"a" => "B", "c" => "D"}
this should work in T-SQL

Since you're using Spring, stick with Spring, don't hack it yourself like the other post posits.
The Spring manual says:
You shouldn't interact directly with the HttpSession for security purposes. There is simply no justification for doing so - always use the SecurityContextHolder instead.
The suggested best practice for accessing the session is:
Object principal = SecurityContextHolder.getContext().getAuthentication().getPrincipal();
if (principal instanceof UserDetails) {
String username = ((UserDetails)principal).getUsername();
} else {
String username = principal.toString();
}
The key here is that Spring and Spring Security do all sorts of great stuff for you like Session Fixation Prevention. These things assume that you're using the Spring framework as it was designed to be used. So, in your servlet, make it context aware and access the session like the above example.
If you just need to stash some data in the session scope, try creating some session scoped bean like this example and let autowire do its magic. :)

Doing this from the app delegate is NOT recommended. AppDelegate manages the app life cycle that relate to launching, suspending, terminating and so on. I suggest doing this from your initial view controller in the viewDidAppear
. You can self.presentViewController
and self.dismissViewController
from the login view controller. Store a bool
key in NSUserDefaults
to see if it's launching for the first time.

This solution works aswell. If there is no Facebook installed, it just runs the normal share-dialog. If there is and you are not logged in, it goes to the login screen. If you are logged in, it will open the share dialog and put in the "Share url" from the Intent Extra.
Intent intent = new Intent(Intent.ACTION_SEND);
intent.putExtra(Intent.EXTRA_TEXT, "Share url");
intent.setType("text/plain");
List<ResolveInfo> matches = getMainFragmentActivity().getPackageManager().queryIntentActivities(intent, 0);
for (ResolveInfo info : matches) {
if (info.activityInfo.packageName.toLowerCase().contains("facebook")) {
intent.setPackage(info.activityInfo.packageName);
}
}
startActivity(intent);
So I realize this is kind of old, but after much Googling, I couldn't find an answer I was happy with, so I came up with my own solution for breaking a FOR loop that immediately stops iteration, and thought I'd share it.
It requires the loop to be in a separate file, and exploits a bug in CMD error handling to immediately crash the batch processing of the loop file when redirecting the STDOUT of DIR to STDIN.
MainFile.cmd
ECHO Simple test demonstrating loop breaking.
ECHO.
CMD /C %~dp0\LOOP.cmd
ECHO.
ECHO After LOOP
PAUSE
LOOP.cmd
FOR /L %%A IN (1,1,10) DO (
ECHO %%A
IF %%A EQU 3 DIR >&0 2>NUL )
)
When run, this produces the following output. You'll notice that both iteration and execution of the loop stops when %A = 3.
:>MainFile.cmd
:>ECHO Simple test demonstrating loop breaking.
Simple test demonstrating loop breaking.
:>ECHO.
:>CMD /C Z:\LOOP.cmd
:>FOR /L %A IN (1 1 10) DO (
ECHO %A
IF %A EQU 3 DIR 1>&0 2>NUL
)
:>(
ECHO 1
IF 1 EQU 3 DIR 1>&0 2>NUL
)
1
:>(
ECHO 2
IF 2 EQU 3 DIR 1>&0 2>NUL
)
2
:>(
ECHO 3
IF 3 EQU 3 DIR 1>&0 2>NUL
)
3
:>ECHO.
:>ECHO After LOOP
After LOOP
:>PAUSE
Press any key to continue . . .
If you need to preserve a single variable from the loop, have the loop ECHO the result of the variable, and use a FOR /F loop in the MainFile.cmd to parse the output of the LOOP.cmd file.
Example (using the same LOOP.cmd file as above):
MainFile.cmd
@ECHO OFF
ECHO.
ECHO Simple test demonstrating loop breaking.
ECHO.
FOR /F "delims=" %%L IN ('CMD /C %~dp0\LOOP.cmd') DO SET VARIABLE=%%L
ECHO After LOOP
ECHO.
ECHO %VARIABLE%
ECHO.
PAUSE
Output:
:>MainFile.cmd
Simple test demonstrating loop breaking.
After LOOP
3
Press any key to continue . . .
If you need to preserve multiple variables, you'll need to redirect them to temporary files as shown below.
MainFile.cmd
@ECHO OFF
ECHO.
ECHO Simple test demonstrating loop breaking.
ECHO.
CMD /C %~dp0\LOOP.cmd
ECHO After LOOP
ECHO.
SET /P VARIABLE1=<%TEMP%\1
SET /P VARIABLE2=<%TEMP%\2
ECHO %VARIABLE1%
ECHO %VARIABLE2%
ECHO.
PAUSE
LOOP.cmd
@ECHO OFF
FOR /L %%A IN (1,1,10) DO (
IF %%A EQU 1 ECHO ONE >%TEMP%\1
IF %%A EQU 2 ECHO TWO >%TEMP%\2
IF %%A EQU 3 DIR >&0 2>NUL
)
Output:
:>MainFile.cmd
Simple test demonstrating loop breaking.
After LOOP
ONE
TWO
Press any key to continue . . .
I hope others find this useful for breaking loops that would otherwise take too long to exit due to continued iteration.

The mechanism of selenium framework:
Here selenium make request to the its server and fetch first subelement with tagname input
WebElement e = e.findElement(By.tagName("input"));
Than you try to receive attribute on that element
object attribute = e.getAttribute("checked")
So either use
findElement(By.attribute("checked")
or use
findElement(By.xpath("\\input[@checked='true']")
P.S. I'm not familiar with java's equivalent of selenium api so some method may be named slightly different.

Easy-peasy ,after installing both the python versions add the paths to the environment variables ;see. Then go to python 2 and python 3 folders and rename them to python2 and python3 respectively as shown
and
. Now in cmd type python2 or python3 to use your required version see
.
$('select>option:eq(3)').attr('selected', 'selected');
One caveat here is if you have javascript watching for select/option's change event you need to add .trigger('change')
so the code become.
$('select>option:eq(3)').attr('selected', 'selected').trigger('change');
because only calling .attr('selected', 'selected')
does not trigger the event
Several good answers to this question. Here's a nice concise one. The first two lines delete the sqlite database. Then the for: loop deletes any objects in the managedObjectContext memory.
NSURL *storeURL = [[(FXYAppDelegate*)[[UIApplication sharedApplication] delegate] applicationDocumentsDirectory] URLByAppendingPathComponent:@"AppName.sqlite"];
[[NSFileManager defaultManager] removeItemAtURL:storeURL error:nil];
for (NSManagedObject *ct in [self.managedObjectContext registeredObjects]) {
[self.managedObjectContext deleteObject:ct];
}

If you have nodejs installed, you can download and install the server using command line:
npm install -g http-server
Change directories to the directory where you want to serve files from:
$ cd ~/projects/angular/current_project
Run the server:

which will produce the message Starting up http-server, serving on:
Available on: http://your_ip:8080 and http://127.0.0.1:8080

One approach would be to take a defaults object and merge it with the target object. The target object would override values in the defaults object.

I've tried every answer on this page (ATOW)
and also some ILGenerator powered solutions (FastMember and Fast.Reflection).
But a compiled Lambda Expression seems to be the fastest.
At least for my use cases (on .Net Core 2.2).
This is what I am using for now:
public static class EnumerableExtensions {
internal static Func<TClass, object> CompileGetter<TClass>(string propertyName) {
var param = Expression.Parameter(typeof(TClass));
var body = Expression.Convert(Expression.Property(param, propertyName), typeof(object));
return Expression.Lambda<Func<TClass, object>>(body,param).Compile();
}
public static DataTable ToDataTable<T>(this IEnumerable<T> collection) {
var dataTable = new DataTable();
var properties = typeof(T)
.GetProperties(BindingFlags.Public | BindingFlags.Instance)
.Where(p => p.CanRead)
.ToArray();
if (properties.Length < 1) return null;
var getters = new Func<T, object>[properties.Length];
for (var i = 0; i < properties.Length; i++) {
var columnType = Nullable.GetUnderlyingType(properties[i].PropertyType) ?? properties[i].PropertyType;
dataTable.Columns.Add(properties[i].Name, columnType);
getters[i] = CompileGetter<T>(properties[i].Name);
}
foreach (var row in collection) {
var dtRow = new object[properties.Length];
for (var i = 0; i < properties.Length; i++) {
dtRow[i] = getters[i].Invoke(row) ?? DBNull.Value;
}
dataTable.Rows.Add(dtRow);
}
return dataTable;
}
}
Only works with properties (not fields) but it works on Anonymous Types.
Simply use the Get-Content
and Set-Content
cmdlets:
Get-Content inputFile1.txt, inputFile2.txt | Set-Content joinedFile.txt
You can concatenate more than two files with this style, too.
If the source files are named similarly, you can use wildcards:
Get-Content inputFile*.txt | Set-Content joinedFile.txt
Note 1: PowerShell 5 and older versions allowed this to be done more concisely using the aliases cat
and sc
for Get-Content
and Set-Content
respectively. However, these aliases are problematic because cat
is a system command in *nix systems, and sc
is a system command in Windows systems - therefore using them is not recommended, and in fact sc
is no longer even defined as of PowerShell Core (v7). The PowerShell team recommends against using aliases in general.
Note 2: Be careful with wildcards - if you try to output to examples.txt
(or similar that matches the pattern), PowerShell will get into an infinite loop! (I just tested this.)
Note 3: Outputting to a file with >
does not preserve character encoding! This is why using Set-Content
is recommended.
There are several tools for converting Matlab to Python code.
The only one that's seen recent activity (last commit from June 2018) is Small Matlab to Python compiler (also developed here: SMOP@chiselapp).
Other options include:
Also, for those interested in an interface between the two languages and not conversion:
pymatlab
: communicate from Python by sending data to the MATLAB workspace, operating on them with scripts and pulling back the resulting data.pymat2
: continuation of the seemingly abandoned PyMat.mlabwrap
, mlabwrap-purepy: make Matlab look like Python library (based on PyMat).oct2py
: run GNU Octave commands from within Python.pymex
: Embeds the Python Interpreter in Matlab, also on File Exchange.matpy
: Access MATLAB in various ways: create variables, access .mat files, direct interface to MATLAB engine (requires MATLAB be installed).Btw might be helpful to look here for other migration tips:
On a different note, though I'm not a fortran
fan at all, for people who might find it useful there is:

You can use nuget.exe to restore your packages or with NuGet 2.7, or above, installed you can simply compile your solution in Visual Studio, which will also restore the missing packages.
For NuGet.exe you can run the following command for each project.
nuget install packages.config
Or with NuGet 2.7 you can restore all packages in the solution using the command line.
nuget restore YourSolution.sln
Both of these will pull down the packages. Your project files will not be modified however when running this command so the project should already have a reference to the NuGet packages. If this is not the case then you can use Visual Studio to install the packages.
With NuGet 2.7, and above, Visual Studio will automatically restore missing NuGet packages when you build your solution so there is no need to use NuGet.exe.
To update all the packages in your solution, first restore them, and then you can either use NuGet.exe to update the packages or from within Visual Studio you can update the packages from the Package Manager Console window, or finally you can use the Manage Packages dialog.
From the command line you can update packages in the solution to the latest version available from nuget.org.
nuget update YourSolution.sln
Note that this will not run any PowerShell scripts in any NuGet packages.
From within Visual Studio you can use the Package Manager Console to also update the packages. This has the benefit that any PowerShell scripts will be run as part of the update where as using NuGet.exe will not run them. The following command will update all packages in every project to the latest version available from nuget.org.
Update-Package
You can also restrict this down to one project.
Update-Package -Project YourProjectName
If you want to reinstall the packages to the same versions as were previously installed then you can use the -reinstall
argument with Update-Package
command.
Update-Package -reinstall
You can also restrict this down to one project.
Update-Package -reinstall -Project YourProjectName
The -reinstall
option will first uninstall and then install the package back again into a project.
Or, you can update the packages using the Manage Packages
dialog.
Updates:
-reinstall

lsof -i:80 -t

Adding local classes, lambdas and the toString()
method to complete the previous two answers. Further, I add arrays of lambdas and arrays of anonymous classes (which do not make any sense in practice though):
package com.example;
public final class TestClassNames {
private static void showClass(Class<?> c) {
System.out.println("getName(): " + c.getName());
System.out.println("getCanonicalName(): " + c.getCanonicalName());
System.out.println("getSimpleName(): " + c.getSimpleName());
System.out.println("toString(): " + c.toString());
System.out.println();
}
private static void x(Runnable r) {
showClass(r.getClass());
showClass(java.lang.reflect.Array.newInstance(r.getClass(), 1).getClass()); // Obtains an array class of a lambda base type.
}
public static class NestedClass {}
public class InnerClass {}
public static void main(String[] args) {
class LocalClass {}
showClass(void.class);
showClass(int.class);
showClass(String.class);
showClass(Runnable.class);
showClass(SomeEnum.class);
showClass(SomeAnnotation.class);
showClass(int[].class);
showClass(String[].class);
showClass(NestedClass.class);
showClass(InnerClass.class);
showClass(LocalClass.class);
showClass(LocalClass[].class);
Object anonymous = new java.io.Serializable() {};
showClass(anonymous.getClass());
showClass(java.lang.reflect.Array.newInstance(anonymous.getClass(), 1).getClass()); // Obtains an array class of an anonymous base type.
x(() -> {});
}
}
enum SomeEnum {
BLUE, YELLOW, RED;
}
@interface SomeAnnotation {}
This is the full output:
getName(): void
getCanonicalName(): void

So, here are the rules. First, lets start with primitive types and void
:
void
, all the four methods simply returns its name.Now the rules for the getName()
method:
getName()
) that is the package name followed by a dot (if there is a package), followed by the name of its class-file as generated by the compiler (whithout the suffix .class
). If there is no package, it is simply the name of the class-file. If the class is an inner, nested, local or anonymous class, the compiler should generate at least one $
in its class-file name. Note that for anonymous classes, the class name would end with a dollar-sign followed by a number.$$Lambda$
, followed by a number, followed by a slash, followed by another number.Z
for boolean
, B
for byte
, S
for short
, C
for char
, I
for int
, J
for long
, F
for float
and D
for double
. For non-array classes and interfaces the class descriptor is L
followed by what is given by getName()
followed by ;
. For array classes, the class descriptor is [
followed by the class descriptor of the component type (which may be itself another array class).getName()
method returns its class descriptor. This rule seems to fail only for array classes whose the component type is a lambda (which possibly is a bug), but hopefully this should not matter anyway because there is no point even on the existence of array classes whose component type is a lambda.Now, the toString()
method:
toString()
returns "interface " + getName()
. If it is a primitive, it returns simply getName()
. If it is something else (a class type, even if it is a pretty weird one), it returns "class " + getName()
.The getCanonicalName()
method:
getCanonicalName()
method returns just what the getName()
method returns.getCanonicalName()
method returns null
for anonymous or local classes and for array classes of those.getCanonicalName()
method returns what the getName()
method would replacing the compiler-introduced dollar-signs by dots.getCanonicalName()
method returns null
if the canonical name of the component type is null
. Otherwise, it returns the canonical name of the component type followed by []
.The getSimpleName()
method:
getSimpleName()
returns the name of the class as written in the source file.getSimpleName()
returns an empty String
.getSimpleName()
just returns what the getName()
would return without the package name. This do not makes much sense and looks like a bug for me, but there is no point in calling getSimpleName()
on a lambda class to start with.getSimpleName()
method returns the simple name of the component class followed by []
. This have the funny/weird side-effect that array classes whose component type is an anonymous class have just []
as their simple names.If that's so bothering, you could try to switch to windows explorer alternative like freecommander which has a toolbar button for that purpose.
Instead of declaring a function in your scope, as suggested by Alex, you can convert it to a simple filter :
angular.module('myApp')
.filter('to_trusted', ['$sce', function($sce){
return function(text) {
return $sce.trustAsHtml(text);
};
}]);
Then you can use it like this :
<div ng-bind-html="preview_data.preview.embed.html | to_trusted"></div>
And here is a working example : http://jsfiddle.net/leeroy/6j4Lg/1/
I've come across the same issue after adding the following dependency:
implementation 'com.evernote:android-state:1.4.1'
annotationProcessor 'com.evernote:android-state-processor:1.4.1'
And the reason was that latest version of evernote uses dependencies to AndroidX, while I had support library version 27.1.1 in my project. So there was an option of upgrading support libraries to 28.0.0, as the other answers suggest, but that was a bit tricky for a large project with lots of custom views. So, I resolved the issue by downgrading evernote version to 1.3.1.
I've tried all the possibilities. Nothing worked for me except the following. var element = document.querySelectorAll("input[id=btn1]"); element[0].setAttribute("disabled",true);
Check your build types of each project under project properties - I bet one or the other will be set to build against .NET XX - Client Profile
.
With inconsistent versions, specifically with one being Client Profile
and the other not, then it works at design time but fails at compile time. A real gotcha.
There is something funny going on in Visual Studio 2010 for me, which keeps setting projects seemingly randomly to Client Profile
, sometimes when I create a project, and sometimes a few days later. Probably some keyboard shortcut I'm accidentally hitting...
When you are done with using your Connection
, you need to explicitly close it by calling its close()
method in order to release any other database resources (cursors, handles, etc.) the connection may be holding on to.
Actually, the safe pattern in Java is to close your ResultSet
, Statement
, and Connection
(in that order) in a finally
block when you are done with them. Something like this:
Connection conn = null;
PreparedStatement ps = null;
ResultSet rs = null;
try {
// Do stuff
...
} catch (SQLException ex) {
// Exception handling stuff
...
} finally {
if (rs != null) {
try {
rs.close();
} catch (SQLException e) { /* Ignored */}
}
if (ps != null) {
try {
ps.close();
} catch (SQLException e) { /* Ignored */}
}
if (conn != null) {
try {
conn.close();
} catch (SQLException e) { /* Ignored */}
}
}
The finally
block can be slightly improved into (to avoid the null check):
} finally {
try { rs.close(); } catch (Exception e) { /* Ignored */ }
try { ps.close(); } catch (Exception e) { /* Ignored */ }
try { conn.close(); } catch (Exception e) { /* Ignored */ }
}
But, still, this is extremely verbose so you generally end up using an helper class to close the objects in null-safe helper methods and the finally
block becomes something like this:
} finally {
DbUtils.closeQuietly(rs);
DbUtils.closeQuietly(ps);
DbUtils.closeQuietly(conn);
}
And, actually, the Apache Commons DbUtils has a DbUtils
class which is precisely doing that, so there isn't any need to write your own.
In order to get a Date (that can be used in JPA later on), I did
Date startOfMonth = Date.from(LocalDate.now().withDayOfMonth(1).atStartOfDay().toInstant(ZoneOffset.UTC));
In C#, a method can return only one value. If you would like to return more than one value, you can use the out keyword. The out modifier returns as return-by-reference. The simplest answer is that the keyword “out” is used to get the value from the method.
In C#, when you pass a value type such as int, float, double etc. as an argument to the method parameter, it is passed by value. Therefore, if you modify the parameter value, it does not affect argument in the method call. But if you mark the parameter with “ref” keyword, it will reflect in the actual variable.
As previously pointed out almost all of the calls are chainable.
So you could call
when(mock.method()).thenReturn(foo).thenReturn(bar).thenThrow(new Exception("test"));
//OR if you're mocking a void method and/or using spy instead of mock
doReturn(foo).doReturn(bar).doThrow(new Exception("Test").when(mock).method();
More info in Mockito's Documenation.
I know this is too late to answer. But you may try these options:
Option 1: (Using curl)
$ch = curl_init();
// set URL and other appropriate options
curl_setopt($ch, CURLOPT_URL, "https://ifconfig.me/");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
// grab URL and pass it to the browser
$ip = curl_exec($ch);
// close cURL resource, and free up system resources
curl_close($ch);
return $ip;
Option 2: (Works good on mac)
return trim(shell_exec("dig +short myip.opendns.com @resolver1.opendns.com"));
Option 3: (Just used a trick)
return str_replace('Current IP CheckCurrent IP Address: ', '', strip_tags(file_get_contents('http://checkip.dyndns.com')));
Might be a reference: https://www.tecmint.com/find-linux-server-public-ip-address/
You have to use Javascript submit
function on your form
object. Take a look in other functions.
<form action="showMessage.jsp" method="post">
<a href="javascript:;" onclick="parentNode.submit();"><%=n%></a>
<input type="hidden" name="mess" value=<%=n%>/>
</form>
You can get SQL Server Management Studio to do it for you:
This will produce a script to set permissions for all selected objects but suppresses the object scripts themselves.
This is based on the dialog for MS SQL 2008 with all other scripting options unchanged from install defaults.
private File convertMultiPartToFile(MultipartFile file ) throws IOException
{
File convFile = new File( file.getOriginalFilename() );
FileOutputStream fos = new FileOutputStream( convFile );

fos.close();
return convFile;
}
In pom.xml file of the project,
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>X.X.X.RELEASE</version>
<relativePath> ../PROJECTNAME/pom.xml</relativePath>
</parent>
Pointing relativepath to the same MAVEN project POM file solved the issue for me.
Setting the image using picture.ImageLocation()
works fine, but you are using a relative path. Check your path against the location of the .exe
after it is built.
For example, if your .exe
is located at:
<project folder>/bin/Debug/app.exe
The image would have to be at:
<project folder>/bin/Image/1.jpg
Of course, you could just set the image at design-time (the Image
property on the PictureBox
property sheet).
If you must set it at run-time, one way to make sure you know the location of the image is to add the image file to your project. For example, add a new folder to your project, name it Image
. Right-click the folder, choose "Add existing item" and browse to your image (be sure the file filter is set to show image files). After adding the image, in the property sheet set the Copy to Output Directory
to Copy if newer
.
At this point the image file will be copied when you build the application and you can use
picture.ImageLocation = @"Image\1.jpg";
If you really want to process your file line by line, a solution might be to use fgetl
:
fopen
fgetl
sscanf
on the character array you just readUnlike the previous answer, this is not very much in the style of Matlab but it might be more efficient on very large files.
Hope this will help.
You can use the following command to install a previous version of an npm package:
npm install packagename@version
Ignoring the specific needs of this question, and while its never a good idea to cast a string to a bool, one way would be to use the ToBoolean() method on the Convert class:
bool val = Convert.ToBoolean("true");
or an extension method to do whatever weird mapping you're doing:
public static class StringExtensions
{
public static bool ToBoolean(this string value)
{
switch (value.ToLower())
{
case "true":
return true;
case "t":
return true;
case "1":
return true;
case "0":
return false;
case "false":
return false;
case "f":
return false;
default:
throw new InvalidCastException("You can't cast that value to a bool!");
}
}
}
Old question, but I just wanted to tack on my solution. This one doesn't require any strange shell tricks, or rely on something that hasn't been around forever.
if [ -n "$(printf '%s\n' "$var" | sed 's/[0-9]//g')" ]; then
echo 'is not numeric'
else
echo 'is numeric'
fi
Basically it just removes all digits from the input, and if you're left with a non-zero-length string then it wasn't a number.
(long dead question, but for future searchers)
Closer to the original poster's code/intent, this works for me under python 2.6
#!/usr/bin/python
import logging
logger = logging.getLogger() # this gets the root logger
lhStdout = logger.handlers[0] # stdout is the only handler initially
# ... here I add my own handlers
f = open("/tmp/debug","w") # example handler
lh = logging.StreamHandler(f)
logger.addHandler(lh)
logger.removeHandler(lhStdout)
logger.debug("bla bla")
The gotcha I had to work out was to remove the stdout handler after adding a new one; the logger code appears to automatically re-add the stdout if no handlers are present.
By default, Android Studio doesn't allow the normal CTRL + Mouse scroll to zoom in or out. You can enable it in the settings, though it seems its location has changed over time. Mac users are well documented in other answers, but I use Windows.
For Windows users in Android Studio 3.4, you go to File -> Settings -> General
, then check the box Change font size (Zoom) with Ctrl+Mouse Wheel
. See below:
I had the same problem. Here's what I figured out:
=BDP(A1&"@BGN Corp", "Issuer_parent_eqy_ticker")
A1 being the ISINs. This will return the ticker number. Then just use the ticker number to get the price.
If you use webpack, you can just use the node.js assertion library. Although they claim that it's "not intended to be a general purpose assertion library", it seems to be more than OK for ad hoc assertions, and it seems no competitor exists in the Node space anyway (Chai is designed for unit testing).
const assert = require('assert');
...
assert(jqXHR.status == 201, "create response should be 201");
You need to use webpack or browserify to be able to use this, so obviously this is only useful if those are already in your workflow.
Actually all of the solutions were pretty complex, and I found a really simple solution (I'm not sure if it is available for all sdk versions). It will open the pdf document in a preview window where the user is able to view and save/share the document:
webView.setDownloadListener(DownloadListener { url, userAgent, contentDisposition, mimetype, contentLength ->
val i = Intent(Intent.ACTION_QUICK_VIEW)
i.data = Uri.parse(url)
if (i.resolveActivity(getPackageManager()) != null) {
startActivity(i)
} else {
val i2 = Intent(Intent.ACTION_VIEW)
i2.data = Uri.parse(url)
startActivity(i2)
}
})
(Kotlin)
Use below code to provide different color to actionbar text and actionbar background just use below theme in manifest against the activity in which you want output :)
<style name="MyTheme" parent="@android:style/Theme.Holo.Light">
<item name="android:actionBarStyle">@style/MyActionBar</item>
</style>
<style name="MyActionBar" parent="@android:style/Widget.Holo.Light.ActionBar">
<item name="android:titleTextStyle">@style/TitleBarTextColor</item>
<item name="android:background">YOUR_COLOR_CODE</item>
</style>
<style name="TitleBarTextColor" parent="@style/TextAppearance.AppCompat.Widget.ActionBar.Title">
<item name="android:textColor">YOUR_COLOR_CODE</item>
</style>
giving a form element a name of submit will simple shadow the submit property . make sure you don't have a form element with the name submit and you should be able to access the submit function just fine .
The word check_
in the name means that if the command (the shell in this case that returns the exit status of the last command (yum
in this case)) returns non-zero status then it raises CalledProcessError
exception. It is by design. If the command that you want to run may return non-zero status on success then either catch this exception or don't use check_
methods. You could use subprocess.call
in your case because you are ignoring the captured output, e.g.:
import subprocess
rc = subprocess.call(['grep', 'pattern', 'file'],
stdout=subprocess.DEVNULL, stderr=subprocess.STDOUT)
if rc == 0: # found
...
elif rc == 1: # not found
...
elif rc > 1: # error
...
You don't need shell=True
to run the commands from your question.
/usr/bin/swiftc --version
You might also try fixing the hosts file.
Keep the vhost file with the fully qualified domain and add the hostname in the hosts file /etc/hosts (debian)
ip.ip.ip.ip name name.domain.com
After restarting apache2, the error should be gone.
[ $(echo $variable_to_test | sed s/\n// | sed s/\ //) == "" ] && echo "String is empty"
Stripping all newlines and spaces from the string will cause a blank one to be reduced to nothing which can be tested and acted upon
Can't get much simpler than this :)
ssh host "test -e /path/to/file"
if [ $? -eq 0 ]; then
# your file exists
fi
As suggested by dimo414, this can be collapsed to:
if ssh host "test -e /path/to/file"; then
# your file exists
fi

* Your variable name and object index need be same
Use a scalar-valued UDF, not a table-value one, then you can use it in a SELECT as you want.
Same with ruby:
echo $(ruby -e 'puts rand(20..65)') #=> 65 (inclusive ending)
echo $(ruby -e 'puts rand(20...65)') #=> 37 (exclusive ending)
Convert.ToDouble(x) can also have a second parameter that indicates the CultureInfo and when you set it to System.Globalization.CultureInfo InvariantCulture the result will allways be the same.
Your code alerts the current value of the dropdown for me, showing that it has properly pushed into the array.
Are you wanting to keep old values and append? You're recreating the array each time, meaning that the old value gets clobbered.
Here's some updated code:
var myarray = [];
$("#test").click(function() {
myarray.push($("#drop").val());
alert(myarray);
});
I could use the GetBody
from Request package.
Look this comment in source code from request.go in net/http:
GetBody defines an optional func to return a new copy of Body. It is used for client requests when a redirect requires reading the body more than once. Use of GetBody still requires setting Body. For server requests it is unused."
GetBody func() (io.ReadCloser, error)
This way you can get the body request without make it empty.
Sample:
getBody := request.GetBody
copyBody, err := getBody()
if err != nil {
// Do something return err
}
http.DefaultClient.Do(request)
foreach(var item in array)
Console.Write(item.ToString() + "\t");
In Java, Dates are internally represented in UTC milliseconds since the epoch (so timezones are not taken into account, that's why you get the same results, as getTime()
gives you the mentioned milliseconds).
In your solution:
Calendar cSchedStartCal = Calendar.getInstance(TimeZone.getTimeZone("GMT"));
long gmtTime = cSchedStartCal.getTime().getTime();
long timezoneAlteredTime = gmtTime + TimeZone.getTimeZone("Asia/Calcutta").getRawOffset();
Calendar cSchedStartCal1 = Calendar.getInstance(TimeZone.getTimeZone("Asia/Calcutta"));
cSchedStartCal1.setTimeInMillis(timezoneAlteredTime);
you just add the offset from GMT to the specified timezone ("Asia/Calcutta" in your example) in milliseconds, so this should work fine.
Another possible solution would be to utilise the static fields of the Calendar
class:
//instantiates a calendar using the current time in the specified timezone
Calendar cSchedStartCal = Calendar.getInstance(TimeZone.getTimeZone("GMT"));
//change the timezone
cSchedStartCal.setTimeZone(TimeZone.getTimeZone("Asia/Calcutta"));
//get the current hour of the day in the new timezone
cSchedStartCal.get(Calendar.HOUR_OF_DAY);
Refer to stackoverflow.com/questions/7695859/ for a more in-depth explanation.
The DateTime.Now
property returns the current date and time, for example 2011-07-01 10:09.45310
.
The DateTime.Today
property returns the current date with the time compnents set to zero, for example 2011-07-01 00:00.00000
.
The DateTime.Today
property actually is implemented to return DateTime.Now.Date
:
public static DateTime Today {
get {
DateTime now = DateTime.Now;
return now.Date;
}
}
You put the if
at the end:
[y for y in a if y not in b]
List comprehensions are written in the same order as their nested full-specified counterparts, essentially the above statement translates to:
outputlist = []
for y in a:
if y not in b:
outputlist.append(y)
Your version tried to do this instead:
outputlist = []
if y not in b:
for y in a:
outputlist.append(y)
but a list comprehension must start with at least one outer loop.
You can achieve what you want by defining a footer for the tableview. See this answer for more details:Eliminate Extra separators below UITableView
I find myself using boost::lexical_cast
for this sort of thing all the time these days.
Example:
std::string input;
std::getline(std::cin,input);
int input_value;
try {
input_value=boost::lexical_cast<int>(input));
} catch(boost::bad_lexical_cast &) {
// Deal with bad input here
}
The pattern works just as well for your own classes too, provided they meet some simple requirements (streamability in the necessary direction, and default and copy constructors).

In C, fgets(), and you need to know the maximum size to prevent truncation.
In CMake you could use find_package
to find libraries you need. There usually is a FindBoost.cmake
along with your CMake installation.
As far as I remember, it will be installed to /usr/share/cmake/Modules/
along with other find-scripts for common libraries. You could just check the documentation in that file for more information about how it works.
An example out of my head:
FIND_PACKAGE( Boost 1.40 COMPONENTS program_options REQUIRED )
INCLUDE_DIRECTORIES( ${Boost_INCLUDE_DIR} )
ADD_EXECUTABLE( anyExecutable myMain.cpp )
TARGET_LINK_LIBRARIES( anyExecutable LINK_PUBLIC ${Boost_LIBRARIES} )
I hope this code helps.
l = [1, 2, 3, 4, 5]
del l[0:3] # Here 3 specifies the number of items to be deleted.
This is the code if you want to delete a number of items from the list. You might as well skip the zero before the colon. It does not have that importance. This might do as well.
l = [1, 2, 3, 4, 5]
del l[:3] # Here 3 specifies the number of items to be deleted.

Well, I now have some modification to my previous answer. I have noticed that none of the answers mentioned IF NOT EXISTS
. So I am going to provide a new solution of it as I have faced some problems altering the table.
IF NOT EXISTS (SELECT * FROM INFORMATION_SCHEMA.columns WHERE table_name = 'TaskSheet' AND column_name = 'IsBilledToClient')
BEGIN
ALTER TABLE dbo.TaskSheet ADD
IsBilledToClient bit NOT NULL DEFAULT ((1))
END
GO
Here TaskSheet
is the particular table name and IsBilledToClient
is the new column which you are going to insert and 1
the default value. That means in the new column what will be the value of the existing rows, therefore one will be set automatically there. However, you can change as you wish with the respect of the column type like I have used BIT
, so I put in default value 1.
I suggest the above system, because I have faced a problem. So what is the problem? The problem is, if the IsBilledToClient
column does exists in the table table then if you execute only the portion of the code given below you will see an error in the SQL server Query builder. But if it does not exist then for the first time there will be no error when executing.
ALTER TABLE {TABLENAME}
ADD {COLUMNNAME} {TYPE} {NULL|NOT NULL}
CONSTRAINT {CONSTRAINT_NAME} DEFAULT {DEFAULT_VALUE}
