I had that problem. And I found this solve. In Android Studio, Open File menu, and go to Project Structure, In Module app, go to dependencies tab and you can add 'com.google.android.gms:play-services:x.x.x' by clicking on + button.
Received this same error on SQL Server 2017 trying to link to Oracle 12c. We were able to use Oracle's SQL Developer to connect to the source database, but the linked server kept throwing the 7302 error.
In the end, we stopped all SQL Services, then re-installed the ODAC components. Started the SQL Services back up and voila!
I liken factories to the concept of libraries. For example you can have a library for working with numbers and another for working with shapes. You can store the functions of these libraries in logically named directories as Numbers
or Shapes
. These are generic types that could include integers, floats, dobules, longs or rectangles, circles, triangles, pentagons in the case of shapes.
The factory petter uses polymorphism, dependency injection and Inversion of control.
The stated purpose of the Factory Patterns is: Define an interface for creating an object, but let subclasses decide which class to instantiate. Factory Method lets a class defer instantiation to subclasses.
So let's say that you are building an Operating System or Framework and you are building all the discrete components.
Here is a simple example of the concept of the Factory Pattern in PHP. I may not be 100% on all of it but it's intended to serve as a simple example. I am not an expert.
class NumbersFactory {
public static function makeNumber( $type, $number ) {
$numObject = null;
$number = null;
switch( $type ) {
case 'float':
$numObject = new Float( $number );
break;
case 'integer':
$numObject = new Integer( $number );
break;
case 'short':
$numObject = new Short( $number );
break;
case 'double':
$numObject = new Double( $number );
break;
case 'long':
$numObject = new Long( $number );
break;
default:
$numObject = new Integer( $number );
break;
}
return $numObject;
}
}

It happened with me as well and fixed in following way:
Created expression based connection string and saved password in a variable and used it.
I have had to do this in cases where documents such as word docs and pdfs were being streamed to the iframe and found a solution that works pretty well. The key is handling the onreadystatechanged
event on the iframe.
Lets say the name of your frame is "myIframe". First somewhere in your code startup (I do it inline any where after the iframe) add something like this to register the event handler:
document.getElementById('myIframe').onreadystatechange = MyIframeReadyStateChanged;
I was not able to use an onreadystatechage attribute on the iframe, I can't remember why, but the app had to work in IE 7 and Safari 3, so that may of been a factor.
Here is an example of a how to get the complete state:
function MyIframeReadyStateChanged()
{
if(document.getElementById('myIframe').readyState == 'complete')
{
// Do your complete stuff here.
}
}
I think the client looks like a normal asynchronous AJAX request, but you expect it to take a "long time" to come back.
The server then looks like this.
while (!hasNewData())
usleep(50);
outputNewData();
So, the AJAX request goes to the server, probably including a timestamp of when it was last update so that your hasNewData()
knows what data you have already got.
The server then sits in a loop sleeping until new data is available. All the while, your AJAX request is still connected, just hanging there waiting for data.
Finally, when new data is available, the server gives it to your AJAX request and closes the connection.
You need to define height of ul or your div and set overflow equals to auto as below:
<ul style="width: 300px; height: 200px; overflow: auto">

The NetBeans cachedir is a directory consisting of files that may become large, may change frequently, and can be deleted and recreated at any time. For example, the results of the Java classpath scan reside in the cachedir.
NetBeans 7.1 and older By default the userdir is inside a (hidden) directory called .netbeans stored in the user's home directory. The home directory is ${HOME} on Unix-like systems, and %USERPROFILE% (usually set to C:\Documents and Settings\) on Windows. The cachedir can be found in var/cache subfolder of the userdir. As the name suggests, the userdir is unique per user. For each version of NetBeans installed, the userdir will be a unique subdirectory such as .netbeans/. To find out your exact userdir location, go to the IDE's main menu, and choose Help > About. (Mac: NetBeans > About NetBeans). NetBeans 7.1 allows to separate the cache directory using a switch --cachedir to a desired location.
Examples A Windows user jdoe running NetBeans 5.0 is likely to find his userdir under C:\Documents and Settings\jdoe.netbeans\5.0\ A Windows Vista user jdoe running NetBeans 5.0 is likely to find his userdir under C:\Users\jdoe.netbeans\5.0\ A Mac OS X user jdoe running NetBeans 5.0 is likely to find his userdir under /Users/jdoe/.netbeans/5.0/ (To open this folder in the Finder, choose Go > Go to Folder from the Finder menu, type /Users/jdoe/.netbeans/5.0/ into the box, and click Go.) A Linux user jdoe running NetBeans 5.0 is likely to find his userdir under /home/jdoe/.netbeans/5.0/
See this documentation at the NetBeans site: NetBeans 7.2 and newer
The standard way to do this is with jQuery UI's CSS Scopes:
<div class="myCssScope">
<!-- dialog goes here -->
</div>
Unfortunately, the jQuery UI dialog moves the dialog DOM elements to the end of the document, to fix potential z-index issues. This means the scoping won't work (it will no longer have a ".myCssScope" ancestor).
Christoph Herold designed a workaround which I've implemented as a jQuery plugin, maybe that will help.
Anaconda is a very large installation ~ 2 GB and is most useful for those users who are not familiar with installing modules or packages with other package managers.
Anaconda seems to be promoting itself as the official package manager of Jupyter. It's not. Anaconda bundles Jupyter, R, python, and many packages with its installation.
Anaconda is not necessary for installing Jupyter Lab or the R kernel. There is plenty of information available elsewhere for installing Jupyter Lab or Notebooks. There is also plenty of information elsewhere for installing R studio. The following shows how to install the R kernel directly from R Studio:
To install the R kernel, without Anaconda, start R Studio. In the R terminal window enter these three commands:
install.packages("devtools")
devtools::install_github("IRkernel/IRkernel")
IRkernel::installspec()
Done. Next time Jupyter is opened, the R kernel will be available.
For me the problem was that there was a div above it (which of course shouldn't have been in the head, but it happens). Firefox didn't mind, but Chrome did.
nVarchar will help you to store Unicode characters. It is the way to go if you want to store localized data.
For those who need the input file to open directly the camera, you just have to declare capture
parameter to the input file, like this :
<input type="file" accept="image/*" capture>
When I first started working with PDF, I found the PDF reference very hard to navigate. It might help you to know that the overview of the file structure is found in syntax, and what Adobe call the document structure is the object structure and not the file structure. That is also found in Syntax. The description of operators is hidden away in Appendix A - very useful for understanding what is happening in content streams. If you ever have the pain of working with colour spaces you will find that hidden in Graphics! Hopefully these pointers will help you find things more quickly than I did.
If you are using windows, pdftron CosEdit allows you to browse the object structure to understand it. There is a free demo available that allows you to examine the file but not save it.
EntityManager interface is similar to sessionFactory in hibernate. EntityManager under javax.persistance package but session and sessionFactory under org.hibernate.Session/sessionFactory package.
Entity manager is JPA specific and session/sessionFactory are hibernate specific.

by this directive you can access the DOM element inside controller
this is sample that help you to focus element inside controller
.directive('scopeElement', function () {
return {
restrict:"A", // E-Element A-Attribute C-Class M-Comments
replace: false,
link: function($scope, elem, attrs) {
$scope[attrs.scopeElement] = elem[0];
}
};
})
now, inside HTML
<input scope-element="txtMessage" >
then, inside controller :
.controller('messageController', ['$scope', function ($scope) {
$scope.txtMessage.focus();
}])

It means you haven't assigned a provisioning profile to the configuration.
Usually it's because "Any iOS SDK" must have a profile and cannot be set to "Don't sign".
All this and more is answered in the TN2250 Tech Note about Code Signing and Troubleshooting.
One reason might be if you install the node after starting the vs code,as vs code terminal integrated or external takes the path value which was at the time of starting the vs code and gives you error:
'node' is not recognized as an internal or external command,operable program or batch file.
A simple restart of vs code will solve the issue.
This should work in C++11 without boost:
namespace std {
template<class T>
T begin(std::pair<T, T> p)
{
return p.first;
}
template<class T>
T end(std::pair<T, T> p)
{
return p.second;
}
}
template<class Iterator>
std::reverse_iterator<Iterator> make_reverse_iterator(Iterator it)
{
return std::reverse_iterator<Iterator>(it);
}
template<class Range>
std::pair<std::reverse_iterator<decltype(begin(std::declval<Range>()))>, std::reverse_iterator<decltype(begin(std::declval<Range>()))>> make_reverse_range(Range&& r)
{
return std::make_pair(make_reverse_iterator(begin(r)), make_reverse_iterator(end(r)));
}
for(auto x: make_reverse_range(r))

}
If you want to filter only items that are less than 7 days old then you just use
Filter
Created
is greater than or equal to
[Today]-7
Note - the screenshot is incorrect.
[Today] is fully supported in view filters in 2007 and onwards (just keep the spaces out!) and you only need to muck around with calculated columns in 2003.
You need to set index=False
in to_excel
in order for it to not write the index column out, this semantic is followed in other Pandas IO tools, see http://pandas.pydata.org/pandas-docs/stable/generated/pandas.DataFrame.to_excel.html and http://pandas.pydata.org/pandas-docs/stable/io.html
You can try with the below commands:
hduser@master:~$ sudo /etc/init.d/mysql stop
[ ok ] Stopping mysql (via systemctl): mysql.service.
hduser@master:~$ sudo /etc/init.d/mysql start
[ ok ] Starting mysql (via systemctl): mysql.service.
It's impossible. You can only find and access views that are currently running. If you want to check the value of ex. TextView used in previus activity you must save the value is SharedPreferences, database, file or pass by Intent.
I will never understand why you need up to 50 reputation to leave a comment but I just had to say that @Curt answer is exactly what I was looking and hopefully someone else.
In my example, I have an ActionFilterAttribute that I was using to update the values of a json patch document. I didn't what the T model was for the patch document to I had to serialize & deserialize it to a plain JsonPatchDocument, modify it, then because I had the type, serialize & deserialize it back to the type again.
Type originalType = //someType that gets passed in to my constructor.
var objectAsString = JsonConvert.SerializeObject(myObjectWithAGenericType);
var plainPatchDocument = JsonConvert.DeserializeObject<JsonPatchDocument>(objectAsString);
var plainPatchDocumentAsString= JsonConvert.SerializeObject(plainPatchDocument);
var modifiedObjectWithGenericType = JsonConvert.DeserializeObject(plainPatchDocumentAsString, originalType );

If you need a custom string sort, you can create a function that returns a number based on the order you specify.
For example, I had pictures that I wanted to sort based on being front side or clasp. So I did the following:
Private Function sortpictures(s As String) As Integer
If Regex.IsMatch(s, "FRONT") Then
Return 0
ElseIf Regex.IsMatch(s, "SIDE") Then
Return 1
ElseIf Regex.IsMatch(s, "CLASP") Then
Return 2
Else
Return 3
End If
End Function
Then I call the sort function like this:
list.Sort(Function(elA As String, elB As String)
Return sortpictures(elA).CompareTo(sortpictures(elB))
End Function)
You can do following:
#!/bin/bash
cd /your/project/directory
# start another shell and replacing the current
exec /bin/bash
EDIT: This could be 'dotted' as well, to prevent creation of subsequent shells.
Example:
. ./previous_script (with or without the first line)
There are multiple methods of creating date as discussed above. I would not repeat same stuff. Here is small method to convert String to Date in Java Script if that is what you are looking for,
function compareDate(str1){
// str1 format should be dd/mm/yyyy. Separator can be anything e.g. / or -. It wont effect
var dt1 = parseInt(str1.substring(0,2));
var mon1 = parseInt(str1.substring(3,5));
var yr1 = parseInt(str1.substring(6,10));
var date1 = new Date(yr1, mon1-1, dt1);
return date1;
}
That DateTime format is actually ISO 8601 DateTime. JSON does not specify any particular format for dates/times. If you Google a bit, you will find plenty of implementations to parse it in Java.
If you are open to using something other than Java's built-in Date/Time/Calendar classes, I would also suggest Joda Time. They offer (among many things) a ISODateTimeFormat
to parse these kinds of strings.
An easier option may be to log the POST data before it gets to the server. For web applications, I use Burp Proxy and set Firefox to use it as an HTTP/S proxy, and then I can watch (and mangle) data 'on the wire' in real time.
For making API requests without a browser, SoapUI is very useful and may show similar info. I would bet that you could probably configure SoapUI to connect through Burp as well (just a guess though).
I'm trying to redirect my current web site to other section on the same page, using JavaScript. This follow code work for me:
location.href='/otherSection'
You can use below query to create table and insert distinct values into this table:
Select Distinct Column1, Column2, Column3 into New_Users from Old_Users
I had this problem in a project this morning. Make sure you specify the base tag in the head section.
It should be like this:
<head>
<base target="name_of_iframe">
</head>
That way when you click a link on the page it will open up inside of the iframe by default.
Hope that helped.
Hmm, there are many solution written for php version lower than 7.1.
Here is an other simple one for those who doesn't want catch all exception and can't make common interfaces:
<?php
$ex = NULL
try {
/* ... */
} catch (FirstException $ex) {
// just do nothing here
} catch (SecondException $ex) {
// just do nothing here
}
if ($ex !== NULL) {
// handle those exceptions here!
}
?>
Something that (surprisingly) hasn't been mentioned here is simple concatenation.
Example:
foo = "seven"
print("She lives with " + foo + " small men")
Result:
She lives with seven small men
Additionally, as of Python 3, the %
method is deprecated. Don't use that.
If you have Perl 5.14 or greater, you can use the /r
option with the substitution operator to perform non-destructive substitution:
print "bla: ", $myvar =~ s/a/b/r, "\n";
In earlier versions you can achieve the same using a do()
block with a temporary lexical variable, e.g.:
print "bla: ", do { (my $tmp = $myvar) =~ s/a/b/; $tmp }, "\n";
Joins in update
statements are non-standard and not supported by all vendors. What you're trying to do can be accomplished with a sub-select:
update
file1
set
firstfield = (select 'stuff' concat something from file2 where substr(file1.field1, 10, 20) = substr(file2.xxx,1,10) )
where
file1.foo like 'BLAH%'
For things like this, you don't blindly keep clicking 'Next', 'Next', and 'I Agree'.
WAMP informs you about this during and before installation:
The MSVC runtime libraries VC9, VC10, VC11 are required for Wampserver 2.4, 2.5 and 3.0, even if you use only Apache and PHP versions with VC11. Runtimes VC13, VC14 is required for PHP 7 and Apache 2.4.17

IMPORTANT NOTE: Be sure to to run all Microsoft Visual C++ installations with administrator privileges (right click ? Run as Administrator). Just missing this small step wasted my entire day.
Just a note that as of Ruby 2.0 there is no need to add # encoding: utf-8
. UTF-8 is automatically detected.
You can also use this code to get LayoutInflater:
LayoutInflater li = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE)
A simple way to downcast in C# is to serialize the parent and then deserialize it into the child.
var serializedParent = JsonConvert.SerializeObject(parentInstance);
Child c = JsonConvert.DeserializeObject<Child>(serializedParent);
I have a simple console app that casts animal into dog, using the above two lines of code over here
Building on @xQbert's answer's, you can avoid the subquery AND make it generic enough to filter by any ID
SELECT id, signin, signout
FROM dTable
INNER JOIN(
SELECT id, MAX(signin) AS signin
FROM dTable
GROUP BY id
) AS t1 USING(id, signin)
You can do it in Python 2.7+ with python-dateutil
(which is insalled on Mac by default):
>>> from datetime import datetime
>>> from dateutil.tz import tzlocal
>>> datetime.now(tzlocal()).isoformat()
'2016-10-22T12:45:45.353489-03:00'
Or you if you want to convert from an existed stored string:
>>> from datetime import datetime
>>> from dateutil.tz import tzlocal
>>> from dateutil.parser import parse
>>> parse("2016-10-21T16:33:27.696173").replace(tzinfo=tzlocal()).isoformat()
'2016-10-21T16:33:27.696173-03:00' <-- Atlantic Daylight Time (ADT)
>>> parse("2016-01-21T16:33:27.696173").replace(tzinfo=tzlocal()).isoformat()
'2016-01-21T16:33:27.696173-04:00' <-- Atlantic Standard Time (AST)
As an alternative solution to the CASE
statement, a table-driven approach can be used:
DECLARE @Product TABLE (ID INT, Obsolete VARCHAR(10), InStock VARCHAR(10))
INSERT INTO @Product VALUES
(1,'N','Y'),
(2,'A','B'),
(3,'N','B'),
(4,'A','Y')
SELECT P.* , ISNULL(Stmt.Saleable,0) Saleable
FROM
@Product P
LEFT JOIN
( VALUES
( 'N', 'Y', 1 )
) Stmt (Obsolete, InStock, Saleable)
ON P.InStock = Stmt.InStock OR P.Obsolete = Stmt.Obsolete
Result:
ID Obsolete InStock Saleable

According to urllib.request.urlretrieve — Python 3.9.2 documentation, The function is ported from the Python 2 module urllib
(as opposed to urllib2
). It might become deprecated at some point in the future.
Because of this, it might be better to use requests.get(url, params=None, **kwargs). Here is a MWE.
import requests
url = 'http://example.com/example.jpg'
response = requests.get(url)
with open(filename, "wb") as f:
f.write(response.content)

Both pandas
and matplotlib.dates
use matplotlib.units
for locating the ticks.
But while matplotlib.dates
has convenient ways to set the ticks manually, pandas seems to have the focus on auto formatting so far (you can have a look at the code for date conversion and formatting in pandas).
So for the moment it seems more reasonable to use matplotlib.dates
(as mentioned by @BrenBarn in his comment).
import numpy as np
import pandas as pd
import matplotlib.pyplot as plt
import matplotlib.dates as dates
idx = pd.date_range('2011-05-01', '2011-07-01')
s = pd.Series(np.random.randn(len(idx)), index=idx)
fig, ax = plt.subplots()
ax.plot_date(idx.to_pydatetime(), s, 'v-')
ax.xaxis.set_minor_locator(dates.WeekdayLocator(byweekday=(1),
interval=1))
ax.xaxis.set_minor_formatter(dates.DateFormatter('%d\n%a'))
ax.xaxis.grid(True, which="minor")
ax.yaxis.grid()
ax.xaxis.set_major_locator(dates.MonthLocator())
ax.xaxis.set_major_formatter(dates.DateFormatter('\n\n\n%b\n%Y'))
plt.tight_layout()
plt.show()

USING A SINGLE TAG FOR ROWS AND SECTIONS
There is a simple way to use tags for transmitting the row/item AND the section of a TableView/CollectionView at the same time.
Encode the IndexPath for your UIView.tag in cellForRowAtIndexPath :
buttonForCell.tag = convertIndexPathToTag(with: indexPath)
Decode the IndexPath from your sender in your target selector:
@IBAction func touchUpInsideButton(sender: UIButton, forEvent event: UIEvent) {
var indexPathForButton = convertTagToIndexPath(from: sender)
}
Encoder and Decoder:
func convertIndexPathToTag(indexPath: IndexPath) -> Int {
var tag: Int = indexPath.row + (1_000_000 * indexPath.section)
return tag
}
func convertTagToIndexPath(from sender: UIButton) -> IndexPath {
var section: Int = Int((Float(sender.tag) / 1_000_000).rounded(.down))
var row: Int = sender.tag - (1_000_000 * section)
return IndexPath(row: row, section: section)
}
Provided that you don’t need more than 4294967296 rows/items on a 32bit device ;-) e.g.

WARNING: Keep in mind that when deleting or inserting rows/items in your TableView/CollectionView you have to reload all rows/items after your insertion/deletion point in order to keep the tag numbers of your buttons in sync with your model.

As a summary, I would describe the wider impact of the repository pattern. It allows all of your code to use objects without having to know how the objects are persisted. All of the knowledge of persistence, including mapping from tables to objects, is safely contained in the repository.
Very often, you will find SQL queries scattered in the codebase and when you come to add a column to a table you have to search code files to try and find usages of a table. The impact of the change is far-reaching.
With the repository pattern, you would only need to change one object and one repository. The impact is very small.
Perhaps it would help to think about why you would use the repository pattern. Here are some reasons:
You have a single place to make changes to your data access
You have a single place responsible for a set of tables (usually)
It is easy to replace a repository with a fake implementation for testing - so you don't need to have a database available to your unit tests
There are other benefits too, for example, if you were using MySQL and wanted to switch to SQL Server - but I have never actually seen this in practice!
Because in C++, the final executable code does not carry any symbol information, it's more or less pure machine code.
Thus, you need a way to describe the interface of a piece of code, that is separate from the code itself. This description is in the header file.
Oracle recommends to add the @Path annotation to all types to be injected when combining JAX-RS with CDI: http://docs.oracle.com/javaee/7/tutorial/jaxrs-advanced004.htm Though this is far from perfect (e.g. you will get warning from Jersey on startup), I decided to take this route, which saves me from maintaining all supported types within a binder.
Example:
@Singleton
@Path("singleton-configuration-service")
public class ConfigurationService {
..
}
@Path("my-path")
class MyProvider {
@Inject ConfigurationService _configuration;
@GET
public Object get() {..}
}
Following code is working for me.
Usings:
using System.IO;
using System.Net;
using Newtonsoft.Json.Linq;
Code:
using (HttpWebResponse response = (HttpWebResponse)request.GetResponse())
{
using (Stream responseStream = response.GetResponseStream())
{
using (StreamReader responseReader = new StreamReader(responseStream))
{
string json = responseReader.ReadToEnd();
string data = JObject.Parse(json)["id"].ToString();
}
}
}
//json = {"kind": "ALL", "id": "1221455", "longUrl": "NewURL"}
Just use that:
var myDateUtc = DateTime.SpecifyKind(DateTime.Parse("Tue, 1 Jan 2008 00:00:00"), DateTimeKind.Utc);
if (myDateUtc.Kind == DateTimeKind.Utc)
{
Console.WriteLine("Yes. I am UTC!");
}
You can test this code using the online c# compiler:
I hope it helps.
I had a similar issue with a ~400MB file. Setting low_memory=False
did the trick for me. Do the simple things first,I would check that your dataframe isn't bigger than your system memory, reboot, clear the RAM before proceeding. If you're still running into errors, its worth making sure your .csv
file is ok, take a quick look in Excel and make sure there's no obvious corruption. Broken original data can wreak havoc...
Instead of catching the error, wouldn't it be possible to test in or before the myplotfunction()
function first if the error will occur (i.e. if the breaks are unique) and only plot it for those cases where it won't appear?!
This can be done more conveniently using Bash's numeric context:
if (( $(echo "$num1 > $num2" |bc -l) )); then
…
fi
Piping through the basic calculator command bc
returns either 1 or 0.
The option -l
is equivalent to --mathlib
; it loads the standard math library.
Enclosing the whole expression between double parenthesis (( ))
will translate these values to respectively true or false.
Please, ensure that the bc
basic calculator package is installed.
This equally works for floats in scientific format, provided a capital letter E
is employed, e.g. num1=3.44E6
While you can do OO in C (e.g. by adding a theType *this
first parameter to methods, and manually handling something like vtables for polymorphism) this is never particularly satisfactory as a design, and will look ugly (even with some pre-processor hacks).
I would suggest at least looking at a re-design to compare how this would work out.
Overall a lot depends on the answer to the key question: if you have working C++ code, why do you want C instead?
If your image is rounded, it would have a height and width of the exact same size (i.e 120). You simply take half of that number and use that in your code (image.layer.cornerRadius = 60).
Easiest Way to do it :
imageView.setColorFilter(Color.rgb(r, g b));
or
imageView.setColorFilter(Color.argb(a, r, g, b));
a, r, g, b : Color argb values.
Vohuman's answer lead me to my own implementation:
$(document).on("vclick", ".className", function() {
// Whatever you want to do
});
Instead of:
$(document).ready(function($) {
$('.className').click(function(){
// Whatever you want to do
});
});
I hope this helps!
Try .html() instead of .val() :
var text = $('#frame1').contents().find('#area1').html();
There are at least two, easy_install and its successor pip.
You need to convert the string to date using the to_date()
function
SELECT * FROM OrderArchive
WHERE OrderDate <= to_date('31-Dec-2014','DD-MON-YYYY');
OR
SELECT * FROM OrderArchive
WHERE OrderDate <= to_date('31 Dec 2014','DD MON YYYY');
OR
SELECT * FROM OrderArchive
WHERE OrderDate <= to_date('2014-12-31','yyyy-MM-dd');
This will work only if OrderDate
is stored in Date format
. If it is Varchar
you should apply to_date()
func on that column also like
SELECT * FROM OrderArchive
WHERE to_date(OrderDate,'yyyy-Mm-dd') <= to_date('2014-12-31','yyyy-MM-dd');
XML Schemas describe hierarchial data models and may not map well to a relational data model. Mapping XSD's to database tables is very similar mapping objects to database tables, in fact you could use a framework like Castor that does both, it allows you to take a XML schema and generate classes, database tables, and data access code. I suppose there are now many tools that do the same thing, but there will be a learning curve and the default mappings will most like not be what you want, so you have to spend time customizing whatever tool you use.
XSLT might be the fastest way to generate exactly the code that you want. If it is a small schema hardcoding it might be faster than evaluating and learing a bunch of new technologies.
Like the message says, is the file somewhere on the project's Java Build Path (e.g. a Source folder)?
This was a straightforward solution for me:
from datetime import timedelta, datetime
today = datetime.today().strftime("%Y-%m-%d")
tomorrow = datetime.today() + timedelta(1)
When you use Task.Run to run a method, Task gets a thread from threadpool to run that method. So from the UI thread's perspective, it is "asynchronous" as it doesn't block UI thread.This is fine for desktop application as you usually don't need many threads to take care of user interactions.
However, for web application each request is serviced by a thread-pool thread and thus the number of active requests can be increased by saving such threads. Frequently using threadpool threads to simulate async operation is not scalable for web applications.
True Async doesn't necessarily involving using a thread for I/O operations, such as file / DB access etc. You can read this to understand why I/O operation doesn't need threads. http://blog.stephencleary.com/2013/11/there-is-no-thread.html
In your simple example,it is a pure CPU-bound calculation, so using Task.Run is fine.
If you want the overflow to wrap: flex-flow: row wrap
Paying tribute to IgorBeaz, you need to stop running the current container. For that you are going to know current CONTAINER ID:
$ docker container ls
You get something like:
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
12a32e8928ef friendlyhello "python app.py" 51 seconds ago Up 50 seconds 0.0.0.0:4000->80/tcp romantic_tesla
Then you stop the container by:
$ docker stop 12a32e8928ef
Finally you try to do what you wanted to do, for example:
$ docker run -p 4000:80 friendlyhello
Even using this won't work. I think the best solution is Browserify:
module.exports = {
func1: function () {
console.log("I am function 1");
},
func2: function () {
console.log("I am function 2");
}
};
-getFunc1.js-
var common = require('./common');
common.func1();
I used the following steps to my web app and I had success:
Add the cors package to the express:
npm install cors --save
Add following lines after the bodyParser configuration. I had some troubles adding before bodyParser:
// enable cors to the server
const corsOpt = {
origin: process.env.CORS_ALLOW_ORIGIN || '*', // this work well to configure origin url in the server
methods: ['GET', 'PUT', 'POST', 'DELETE', 'OPTIONS'], // to works well with web app, OPTIONS is required
allowedHeaders: ['Content-Type', 'Authorization'] // allow json and token in the headers
};
app.use(cors(corsOpt)); // cors for all the routes of the application
app.options('*', cors(corsOpt)); // automatic cors gen for HTTP verbs in all routes, This can be redundant but I kept to be sure that will always work.
According to your explanation you haven't included your Class2.cs
in your project. You have just created the required Class file but haven't included that in the project.
The Class2.cs was created with [File] -> [New] -> [File] -> [C# class] and saved in the same folder where program.cs lives.
Do the following to overcome this,
Simply Right click
on your project then -> [Add] - > [Existing Item...] : Select Class2.cs
and press OK
Problem should be solved now.
Furthermore, when adding new classes use this procedure,
Right click
on project -> [Add] -> Select Required Item (ex - A class, Form etc.)
First, you do not need android:process=":remote"
, so please remove it, since all it will do is take up extra RAM for no benefit.
Second, since the <service>
element contains an action string, use it:
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Intent intent=new Intent("com.sample.service.serviceClass");
this.startService(intent);
}
There is the "Compare" plugin. You can install it via Plugins > Plugin Manager.
Alternatively you can install a specialized file compare software like WinMerge.
Use window.open()
. It's pretty straightforward !
In your component.html
file-
<a (click)="goToLink("www.example.com")">page link</a>
In your component.ts
file-
goToLink(url: string){
window.open(url, "_blank");
}
func firstIndex(of element: Element) -> Int?
var alphabets = ["A", "B", "E", "D"]
Example1
let index = alphabets.firstIndex(where: {$0 == "A"})
Example2
if let i = alphabets.firstIndex(of: "E") {
alphabets[i] = "C" // i is the index
}
print(alphabets)
// Prints "["A", "B", "C", "D"]"
I believe that Notepad++ has this feature.
Edit (for newer versions)
Install the "XML Tools" plugin (Menu Plugins, Plugin Manager)
Then run: Menu Plugins, Xml Tools, Pretty Print (XML only - with line breaks)
Original answer (for older versions of Notepad++)
Notepad++ menu: TextFX -> HTML Tidy -> Tidy: Reindent XML
This feature however wraps XMLs and that makes it look 'unclean'. To have no wrap,
C:\Program Files\Notepad++\plugins\Config\tidy\TIDYCFG.INI
, [Tidy: Reindent XML]
and add wrap:0
so that it looks like this: [Tidy: Reindent XML] input-xml: yes indent:yes wrap:0
Well at the place of openssl ... you have to put actually the path to your openssl folder that you have downloaded. Your actual command should look like:
keytool -exportcert -alias androiddebugkey -keystore ~/.android/debug.keystore | "C:\Users\abc\openssl\bin\openssl.exe" sha1 -binary | "C:\Users\abc\openssl\bin\openssl.exe" base64
Remember, path that you will enter will be the path where you have installed the openssl...hope this helps..:-)
Edit:
you can download openssl for windows 32 and 64 bit from the respective links below:
The simplest way to log out and redirect back to the login or index:
<?php
if (!isset($_SESSION)) { session_start(); }
$_SESSION = array();
session_destroy();
header("Location: login.php"); // Or wherever you want to redirect
exit();
?>
I worked out a solution on Xcode 6.4 in swift.
// I saved the credentials on a click event to phone memory
@IBAction func gotobidderpage(sender: AnyObject) {
if (usernamestring == "bidder" && passwordstring == "day303")
{
rolltype = "1"
NSUserDefaults.standardUserDefaults().setObject(usernamestring, forKey: "username")
NSUserDefaults.standardUserDefaults().setObject(passwordstring, forKey: "password")
NSUserDefaults.standardUserDefaults().setObject(rolltype, forKey: "roll")
self.performSegueWithIdentifier("seguetobidderpage", sender: self)
}
// Retained saved credentials in app delegate.swift and performed navigation after condition check
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
let usernamestring = NSUserDefaults.standardUserDefaults().stringForKey("username")
let passwordstring = NSUserDefaults.standardUserDefaults().stringForKey("password")
let rolltypestring = NSUserDefaults.standardUserDefaults().stringForKey("roll")
if (usernamestring == "bidder" && passwordstring == "day303" && rolltypestring == "1")
{
// Access the storyboard and fetch an instance of the view controller
var storyboard = UIStoryboard(name: "Main", bundle: nil)
var viewController: BidderPage = storyboard.instantiateViewControllerWithIdentifier("bidderpageID") as! BidderPage
// Then push that view controller onto the navigation stack
var rootViewController = self.window!.rootViewController as! UINavigationController
rootViewController.pushViewController(viewController, animated: true)
}
// Override point for customization after application launch.
return true
}
Hope it helps !
Sorry, I might take it too simple, but doesn't this do the job? (in 1.3 secs for 1E6 values on my machine):
t0 <- Sys.time()
summary(as.factor(round(rnorm(1e6), 2)))[1]
Sys.time()-t0
You just have to replace the "round(rnorm(1e6),2)" with your vector.
When you are using GET Method the contract must be this.
[WebGet(UriTemplate = "/", BodyStyle = WebMessageBodyStyle.Bare, ResponseFormat = WebMessageFormat.Json)]
List<User> Get();
with this we have a json without the boot parameter

In my case working with python 2.7 with numpy version 1.15.0, it worked with
pip install statsmodels=="0.10.0"
I find the most valuable feature of .FormulaR1C1 is sheer speed. Versus eg a couple of very large loops filling some data into a sheet, If you can convert what you are doing into a .FormulaR1C1 form. Then a single operation eg myrange.FormulaR1C1 = "my particular formuala" is blindingly fast (can be a thousand times faster). No looping and counting - just fill the range at high speed.
try this
data => {
this.results = [...this.results, ...data.results];
this._next = data.next;
}
In Chrome it's possible to hide this automatic header/footer using
@page { margin: 0; }
Since the contents will extend to page's limits, the page printing header/footer will be absent. You should, of course, in this case, set some margins/paddings in your body element so that the content won't extend all the way to the page's edge. Since common printers just can't get no-margins printing and it's probably not what you want, you should use something like this:
@media print {
@page { margin: 0; }
body { margin: 1.6cm; }
}
As Martin pointed out in a comment, if the page have a long element that scrolls past one page (like a big table), the margin is ignored and the printed version will look weird.
At the time original of this answer (May 2013), it only worked on Chrome, not sure about it now, never needed to try again. If you need support for a browser that can't hable, you can create a PDF on the fly and print that (you can create a self-printing PDF embedding JavaScript on it), but that's a huge hassle.
mysql_real_escape_string() or str_replace() function will help you to solve your problem.
Something simple like this can be done using subqueries in the select
clause:
select ((select sum(hours) from resource) +
(select sum(hours) from projects-time)
) as totalHours
For such a simple query as this, such a subselect is reasonable.
In some databases, you might have to add from dual
for the query to compile.
If you want to output each individually:
select (select sum(hours) from resource) as ResourceHours,
(select sum(hours) from projects-time) as ProjectHours
If you want both and the sum, a subquery is handy:
select ResourceHours, ProjectHours, (ResourceHours+ProjecctHours) as TotalHours
from (select (select sum(hours) from resource) as ResourceHours,
(select sum(hours) from projects-time) as ProjectHours
) t
If None
is a valid data value then you need to the variable another way. You could use:
var = object()
This sentinel is suggested by Nick Coghlan.
You could use this pretty simple solution:
Array.from(document.querySelectorAll('div'))
.find(el => el.textContent === 'SomeText, text continues.');
The Array.from
will convert the NodeList to an array (there are multiple methods to do this like the spread operator or slice)
The result now being an array allows for using the Array.find
method, you can then put in any predicate. You could also check the textContent with a regex or whatever you like.
Note that Array.from
and Array.find
are ES2015 features. Te be compatible with older browsers like IE10 without a transpiler:
Array.prototype.slice.call(document.querySelectorAll('div'))
.filter(function (el) {
return el.textContent === 'SomeText, text continues.'
})[0];
Dynamic Programming
Definition
Dynamic programming (DP) is a general algorithm design technique for solving problems with overlapping sub-problems. This technique was invented by American mathematician “Richard Bellman” in 1950s.
Key Idea
The key idea is to save answers of overlapping smaller sub-problems to avoid recomputation.
Dynamic Programming Properties
with prototype and without space :
String.prototype.trimToLength = function (trimLenght) {
return this.length > trimLenght ? this.substring(0, trimLenght - 3) + '...' : this
};
Your updateVelocity()
method is missing the explicit self
parameter in its definition.
Should be something like this:
def updateVelocity(self):
for x in range(0,len(self.velocity)):
self.velocity[x] = 2*random.random()*(self.pbestx[x]-self.current[x]) + 2 \
* random.random()*(self.gbest[x]-self.current[x])
Your other methods (except for __init__
) have the same problem.
I set the below 3 styles to my img

It also works width

Problem with Access strategies
As a JPA provider, Hibernate can introspect both the entity attributes (instance fields) or the accessors (instance properties). By default, the placement of the
@Id
annotation gives the default access strategy. When placed on a field, Hibernate will assume field-based access. Placed on the identifier getter, Hibernate will use property-based access.
Field-based access
When using field-based access, adding other entity-level methods is much more flexible because Hibernate won’t consider those part of the persistence state
@Entity
public class Simple {
@Id
private Integer id;
@OneToMany(targetEntity=Student.class, mappedBy="college",
fetch=FetchType.EAGER)
private List<Student> students;
//getter +setter
}
Property-based access
When using property-based access, Hibernate uses the accessors for both reading and writing the entity state
@Entity
public class Simple {
private Integer id;
private List<Student> students;
@Id
public Integer getId() {
return id;
}
public void setId( Integer id ) {
this.id = id;
}
@OneToMany(targetEntity=Student.class, mappedBy="college",
fetch=FetchType.EAGER)
public List<Student> getStudents() {
return students;
}
public void setStudents(List<Student> students) {
this.students = students;
}
}
But you can't use both Field-based and Property-based access at the same time. It will show like that error for you
For more idea follow this
The error you get is due to the CORS standard, which sets some restrictions on how JavaScript can perform ajax requests.
The CORS standard is a client-side standard, implemented in the browser. So it is the browser which prevent the call from completing and generates the error message - not the server.
Postman does not implement the CORS restrictions, which is why you don't see the same error when making the same call from Postman.
Here's what I would do to get what you want :
$(document).ready(function() {
$(".testform").click(function(event) {
if( !confirm('Are you sure that you want to submit the form') )
event.preventDefault();
});
});
A slight explanation about how that code works, When the user clicks the button then the confirm dialog is launched, in case the user selects no the default action which was to submit the form is not carried out. Upon confirmation the control is passed to the browser which carries on with submitting the form. We use the standard JavaScript confirm here.
if($('#user_inp').length > 0 && $('#user_inp').val() != '')
{
$('#user_inp').css({"font-size":"18px"});
$('#user_line').css({"background-color":"#4cae4c","transition":"0.5s","height":"2px"});
$('#username').css({"color":"#4cae4c","transition":"0.5s","font-size":"18px"});

A generic answer on how to handle click
events with KnockoutJS...
Not a straight up answer to the question as asked, but probably an answer to the question most Googlers landing here have: use the click
binding from KnockoutJS instead of onclick
. Like this:
function Item(parent, txt) {_x000D_
var self = this;_x000D_
_x000D_
self.doStuff = function(data, event) {_x000D_

**A note about the actual question...*
The actual question has one interesting bit:
// Uh oh! Modifying the DOM....
place.innerHTML = "somthing"
Don't do that! Don't modify the DOM like that when using an MVVM framework like KnockoutJS, especially not the piece of the DOM that is your own parent. If you would do this the button would disappear (if you replace your parent's innerHTML
you yourself will be gone forever ever!).
Instead, modify the View Model in your handler instead, and have the View respond. For example:
function RootVm() {_x000D_
var self = this;_x000D_
self.buttonWasClickedOnce = ko.observable(false);_x000D_
self.toggle = function(data, event) {_x000D_
self.buttonWasClickedOnce(!self.buttonWasClickedOnce());_x000D_
};_x000D_
}_x000D_
_x000D_
ko.applyBindings(new RootVm());

Iterate over any item in the array. For every item you visit, check that item's id. If it's a match, return it.
If you just want teh codez:
function getId(array, id) {
for (var i = 0, len = array.length; i < len; i++) {
if (array[i].id === id) {
return array[i];
}
}
return null; // Nothing found
}
And the same thing using ECMAScript 5's Array methods:
function getId(array, id) {
var obj = array.filter(function (val) {
return val.id === id;
});
// Filter returns an array, and we just want the matching item.
return obj[0];
}
Use git reset --soft HEAD~
in the cmd from the .sln folder
I was facing it today and was overwhelmed that VSCode
suggests such thing, whereas it's big brother Visual Studio
doesn't.
Most of the answers were helpful; if I have more commits that were made before, losing them all would be frustrating.
Moreover, if VSCode
does it in half a second, it shouldn't be complex.
Only jessehouwing's answer was the closest to a simple solution.
Go to Team Explorer
-> Sync
.
There you'd see the all the commits. Press the Actions
dropdown and Open Command Prompt
You'll have the cmd window prompted, there write git reset --soft HEAD~
.
If there are multiple undesired commits, add the amount after the ~
(i.e git reset --soft HEAD~5
)
(If you're not using git
, check colloquial usage).
I hope it will help, and hopefully in the next version VS team will add it builtin

adapter.setOnCardClickListner(this);
Here is your Adapter class.
public class UsersAdapter extends RecyclerView.Adapter<UsersAdapter.UserViewHolder> {
private ArrayList<User> mDataSet;
OnCardClickListner onCardClickListner;
public UsersAdapter(ArrayList<User> mDataSet) {
this.mDataSet = mDataSet;
}
@Override
public UserViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View v = LayoutInflater.from(parent.getContext()).inflate(R.layout.user_row_layout, parent, false);
UserViewHolder userViewHolder = new UserViewHolder(v);
return userViewHolder;
}
@Override
public void onBindViewHolder(UserViewHolder holder, final int position) {
holder.name_entry.setText(mDataSet.get(position).getUser_name());
holder.cardView.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
onCardClickListner.OnCardClicked(v, position);
}
});
}
@Override
public int getItemCount() {
return mDataSet.size();
}
@Override
public void onAttachedToRecyclerView(RecyclerView recyclerView) {
super.onAttachedToRecyclerView(recyclerView);
}
public static class UserViewHolder extends RecyclerView.ViewHolder {
CardView cardView;
TextView name_entry;
public UserViewHolder(View itemView) {
super(itemView);
cardView = (CardView) itemView.findViewById(R.id.user_layout);
name_entry = (TextView) itemView.findViewById(R.id.name_entry);
}
}
public interface OnCardClickListner {
void OnCardClicked(View view, int position);
}
public void setOnCardClickListner(OnCardClickListner onCardClickListner) {
this.onCardClickListner = onCardClickListner;
}
}
After this you will get this override method in your activity.
@Override
public void OnCardClicked(View view, int position) {
Log.d("OnClick", "Card Position" + position);
}
If you are looking to style a file input element, look at open file dialog box in javascript. If you are looking to grab the files associated with a file input element, you must do something like this:
inputElement.onchange = function(event) {
var fileList = inputElement.files;
//TODO do something with fileList.
}
See this MDN article for more info on the FileList
type.
Note that the code above will only work in browsers that support the File API. For IE9 and earlier, for example, you only have access to the file name. The input element has no files
property in non-File API browsers.
Try the following instead:
String[] listOfPipes = System.IO.Directory.GetFiles(@"\\.\pipe\");
you can use setSeconds
method by getting seconds from today and just adding 10 seconds in it
var today = new Date();
today.setSeconds(today.getSeconds() + 10);
You can add 10 *1000 milliseconds to the new date:
var today = new Date();
today = new Date(today.getTime() + 1000*10);
You can use setTime
:
today.setTime(now.getTime() + 10000)
If the data should survive throughout the application lifecycle and shared among multiple fragments or activities, a Model
class might come into consideration, which has got less serialization overhead.
Check this design example
Is the
???
free to be defined by the user?
Yes.
or is it supplied by the HTML?
No. HTML has nothing to do with that. Read below.
Is it possible for me to define the

asabcdefg
?
Yes.
If you want to send the following data to the web server:
name = John
age = 12
using application/x-www-form-urlencoded
would be like this:
name=John&age=12
As you can see, the server knows that parameters are separated by an ampersand &
. If &
is required for a parameter value then it must be encoded.
So how does the server know where a parameter value starts and ends when it receives an HTTP request using multipart/form-data
?
Using the boundary, similar to &
.
For example:
--XXX
Content-Disposition: form-data; name="name"
John
--XXX
Content-Disposition: form-data; name="age"
12
--XXX--
In that case, the boundary value is XXX
. You specify it in the Content-Type
header so that the server knows how to split the data it receives.
So you need to:
Use a value that won't appear in the HTTP data sent to the server.
Be consistent and use the same value everywhere in the request message.
Not sure it will fit all use-cases but I often use a simple trick to get the wrapping behaviour:
put your Label
with AutoSize=false
inside a 1x1 TableLayoutPanel
which will take care of the Label
's size.
Leveraging from the good answers above and assuming you were only using plt as in
import matplotlib.pyplot as plt
then you can get all four plot limits using plt.axis()
as in the following example.
import matplotlib.pyplot as plt
x = [1, 2, 3, 4, 5, 6, 7, 8] # fake data
y = [1, 2, 3, 4, 3, 2, 5, 6]
plt.plot(x, y, 'k')
xmin, xmax, ymin, ymax = plt.axis()
s = 'xmin = ' + str(round(xmin, 2)) + ', ' + \
'xmax = ' + str(xmax) + '\n' + \
'ymin = ' + str(ymin) + ', ' + \
'ymax = ' + str(ymax) + ' '
plt.annotate(s, (1, 5))
plt.show()
The linker tells you that you have the variable k
defined multiple times. Indeed, you have a definition in A.cpp and another in B.cpp. Both compilation units produce a corresponding object file that the linker uses to create your program. The problem is that in your case the linker does not know whic definition of k
to use. In C++ you can have only one defintion of the same construct (variable, type, function).
To fix it, you will have to decide what your goal is
k
, you can use an anonymous namespace in both .cpp files, then refer to k
as you are doing now:.
namespace {
int k;
}
k
s to something else, thus avoiding the duplicate defintion.k
and use that in both .cpp files, you need to declare in one as extern int k;
, and leave it as it is in the other. This will tell the linker to use the one definition (the unchanged version) in both cases -- extern
implies that the variable is defined in another compilation unit.An old tip...
var daddy = window.self;
daddy.opener = window.self;
daddy.close();
Try this:
public static int? ParseNullableInt(this string value)
{
int intValue;
if (int.TryParse(value, out intValue))
return intValue;
return null;
}
Googling gives me this:
Command A & Command B
Execute Command A, then execute Command B (no evaluation of anything)
Command A | Command B
Execute Command A, and redirect all its output into the input of Command B
Command A && Command B
Execute Command A, evaluate the errorlevel after running and if the exit code (errorlevel) is 0, only then execute Command B
Command A || Command B
Execute Command A, evaluate the exit code of this command and if it's anything but 0, only then execute Command B

@Sheridan thx.. if I try your example with "DisplayedImagePath" on both sides, it works with absolute path as you show.
As for the relative paths, this is how I always connect relative paths, I first include the subdirectory (!) and the image file in my project.. then I use ~ character to denote the bin-path..
public string DisplayedImagePath
{
get { return @"~\..\images\osc.png"; }
}
This was tested, see below my Solution Explorer in VS2015..
Note: if you want a Click event, use the Button tag around the image,
<Button Click="image_Click" Width="128" Height="128" Grid.Row="2" VerticalAlignment="Top" HorizontalAlignment="Left">_x000D_
<Image x:Name="image" Source="{Binding DisplayedImagePath}" Margin="0,0,0,0" />_x000D_
</Button>

If you want to get the "4x speed increase" reported by wcoenen, then if it's not obvious: replace hex.Substring(i, 2)
with hex[i]+hex[i+1]
You could also take it a step further and get rid of the i+=2
by using i++
in both places.
In CentOS this might be caused by the SELinux policy. Execute the following code to see if it is enabled.
getsebool httpd_can_sendmail
You can enable it by calling the command below. The -P parameter makes it permanent.
setsebool -P httpd_can_sendmail 1
Also make sure your Workspace Settings aren't overriding your User Settings. The UI doesn't make it very obvious which settings you're editing and "File > Preferences > Settings" defaults to User Settings even though Workspace Settings trump User Settings.
You can also edit Workspace settings directly: /.vscode/settings.json
Use CopyOnWriteArrayList
and if you want to remove it, do the following:
for (Iterator<String> it = userList.iterator(); it.hasNext() ;)
{
if (wordsToRemove.contains(word))
{
it.remove();
}
}
If X

I would recommend looking at the numpy broadcasting rules.
Another pure css based solution that is based on two clipped rounded elements that i rotate to get to the right angle:
http://jsfiddle.net/maayan/byT76/
That's the basic css that enables it:

top:0;left:0;
width:200px;
height:200px;
clip:rect(0px,200px,200px,100px);
}
.slice1 {
position:absolute;
width:200px;
height:200px;
clip:rect(0px,100px,200px,0px);
-moz-border-radius:100px;
-webkit-border-radius:100px;
border-radius:100px;
background-color:#f7e5e1;
border-color:#f7e5e1;
-moz-transform:rotate(0);
-webkit-transform:rotate(0);
-o-transform:rotate(0);
transform:rotate(0);
}
.clip2
{
position:absolute;
top:0;left:0;

height:200px;
clip:rect(0,100px,200px,0px);
}

border-color:#f7e5e1;
-moz-transform:rotate(0);

transform:rotate(0);
}
and the js rotates it as required.

it doenst work for me but it prints the correct element to the console
this is the code:
function click(x, y)
{
var ev = new MouseEvent('click', {
'view': window,
'bubbles': true,
'cancelable': true,
'screenX': x,
'screenY': y
});
var el = document.elementFromPoint(x, y);
console.log(el); //print element to console
el.dispatchEvent(ev);
}
click(400, 400);
If you need to get the int value, just have a getter for the value in your ENUM:
private enum DownloadType {
AUDIO(1), VIDEO(2), AUDIO_AND_VIDEO(3);
private final int value;
private DownloadType(int value) {
this.value = value;
}
public int getValue() {
return value;
}
}
public static void main(String[] args) {
System.out.println(DownloadType.AUDIO.getValue()); //returns 1
System.out.println(DownloadType.VIDEO.getValue()); //returns 2
System.out.println(DownloadType.AUDIO_AND_VIDEO.getValue()); //returns 3
}
Or you could simple use the ordinal()
method, which would return the position of the enum constant in the enum.
private enum DownloadType {
AUDIO(0), VIDEO(1), AUDIO_AND_VIDEO(2);
//rest of the code
}
System.out.println(DownloadType.AUDIO.ordinal()); //returns 0
System.out.println(DownloadType.VIDEO.ordinal()); //returns 1
System.out.println(DownloadType.AUDIO_AND_VIDEO.ordinal()); //returns 2

Although using const
to define functions seems like a hack, but it comes with some great advantages that make it superior (in my opinion)
It makes the function immutable, so you don't have to worry about that function being changed by some other piece of code.
You can use fat arrow syntax, which is shorter & cleaner.
Using arrow functions takes care of this
binding for you.
example with function
// define a function_x000D_
function add(x, y) { return x + y; }_x000D_
_x000D_
// use it_x000D_
console.log(add(1, 2)); // 3_x000D_
_x000D_
// oops, someone mutated your function_x000D_
add = function (x, y) { return x - y; };_x000D_
_x000D_
// now this is not what you expected_x000D_
console.log(add(1, 2)); // -1
_x000D_
same example with const
// define a function (wow! that is 8 chars shorter)_x000D_
const add = (x, y) => x + y;_x000D_
_x000D_
// use it_x000D_
console.log(add(1, 2)); // 3_x000D_
_x000D_
// someone tries to mutate the function_x000D_
add = (x, y) => x - y; // Uncaught TypeError: Assignment to constant variable._x000D_
// the intruder fails and your function remains unchanged

I ran across this post today as I was running into the same issue and had the same problem of the javascript not running with the CDATA tags listed above. I corrected the CDATA tags to look like:

Then everything worked perfectly!
file element has and array call files
it contain all necessary stuff you need
var file = document.getElementById("upload");
file.addEventListener("change", function() {
for (var i = 0; i < file.files.length; i++) {
console.log(file.files[i].name);
}
}, false);
I believe my input is controlled since it has a value.
For an input to be controlled, its value must correspond to that of a state variable.
That condition is not initially met in your example because this.state.name
is not initially set. Therefore, the input is initially uncontrolled. Once the onChange
handler is triggered for the first time, this.state.name
gets set. At that point, the above condition is satisfied and the input is considered to be controlled. This transition from uncontrolled to controlled produces the error seen above.
By initializing this.state.name
in the constructor:
e.g.
this.state = { name: '' };
the input will be controlled from the start, fixing the issue. See React Controlled Components for more examples.
Unrelated to this error, you should only have one default export. Your code above has two.
Here's an example to make it clear how things work with GCC when static libraries are involved. So let's assume we have the following scenario:
myprog.o
- containing main()
function, dependent on libmysqlclient
libmysqlclient
- static, for the sake of the example (you'd prefer the shared library, of course, as the libmysqlclient
is huge); in /usr/local/lib
; and dependent on stuff from libz
libz
(dynamic)How do we link this? (Note: examples from compiling on Cygwin using gcc 4.3.4)
gcc -L/usr/local/lib -lmysqlclient myprog.o
# undefined reference to `_mysql_init'
# myprog depends on libmysqlclient
# so myprog has to come earlier on the command line
gcc myprog.o -L/usr/local/lib -lmysqlclient
# undefined reference to `_uncompress'
# we have to link with libz, too
gcc myprog.o -lz -L/usr/local/lib -lmysqlclient
# undefined reference to `_uncompress'
# libz is needed by libmysqlclient
# so it has to appear *after* it on the command line
gcc myprog.o -L/usr/local/lib -lmysqlclient -lz
# this works
As a quick example:
var name = 'jack';
var age = 40;
console.log('%s is %d yrs old',name,age);
The output is:
jack is 40 yrs old
Here is a recursive solution in PHP. WhirlWind's post accurately describes the logic. It's worth mentioning that generating all permutations runs in factorial time, so it might be a good idea to use an iterative approach instead.
public function permute($sofar, $input){
for($i=0; $i < strlen($input); $i++){
$diff = strDiff($input,$input[$i]);
$next = $sofar.$input[$i]; //next contains a permutation, save it
$this->permute($next, $diff);
}
}
The strDiff function takes two strings, s1
and s2
, and returns a new string with everything in s1
without elements in s2
(duplicates matter). So, strDiff('finish','i')
=> 'fnish'
(the second 'i' is not removed).
In my case, six was installed for python 2.7 and for 3.7 too, and both pip install six
and pip3 install six
reported it as already installed, while I still had apps (particularly, the apt program itself) complaining about missing six.
The solution was to install it for python3.6 specifically:
/usr/bin/python3.6 -m pip install six
Java passes parameters by value, but for object variables, the values are essentially references to objects. Since arrays are objects the following example code shows the difference.
public static void dummyIncrease(int[] x, int y)
{
x[0]++;
y++;
}
public static void main(String[] args)
{
int[] arr = {3, 4, 5};
int b = 1;
dummyIncrease(arr, b);
// arr[0] is 4, but b is still 1
}
main()
arr +---+ +---+---+---+
| # | ----> | 3 | 4 | 5 |
+---+ +---+---+---+
b +---+ ^
| 1 | |
+---+ |
|
dummyIncrease() |
x +---+ |
| # | ------------+
+---+
y +---+
| 1 |
+---+
Put all the 6 classes to 6 different projects. Then create jar files of all the 6 projects. In this manner you will get 6 executable jar files.

I would rather create a map
export class item{

let caches = new Map<string, item>();
and then you can simply
this.caches[newitem.id] = newitem;
even
this.caches.set(newitem.id, newitem);

This is what I did to get formatted date from front end
@RequestMapping(value = "/{dateString}", method = RequestMethod.GET)
@ResponseBody
public HttpStatus getSomething(@PathVariable @DateTimeFormat(iso = DateTimeFormat.ISO.DATE) String dateString) {
return OK;
}
You can use it to get what you want.
To search for files containing all the words in any order anywhere:
grep -ril \'action\' | xargs grep -il \'model\' | xargs grep -il \'view_type\'
The first grep kicks off a recursive search (r
), ignoring case (i
) and listing (printing out) the name of the files that are matching (l
) for one term ('action'
with the single quotes) occurring anywhere in the file.
The subsequent greps search for the other terms, retaining case insensitivity and listing out the matching files.
The final list of files that you will get will the ones that contain these terms, in any order anywhere in the file.
Based on K3N answer, I rewrite code generally for anyone wants
var oc = document.createElement('canvas'), octx = oc.getContext('2d');
oc.width = img.width;
oc.height = img.height;
octx.drawImage(img, 0, 0);
while (oc.width * 0.5 > width) {
oc.width *= 0.5;
oc.height *= 0.5;
octx.drawImage(oc, 0, 0, oc.width, oc.height);
}
oc.width = width;
oc.height = oc.width * img.height / img.width;
octx.drawImage(img, 0, 0, oc.width, oc.height);
UPDATE JSFIDDLE DEMO
Here is my ONLINE DEMO
If t
is a matrix, you need to use the element-wise multiplication or exponentiation. Note the dot.
x = exp( -t.^2 )
or
x = exp( -t.*t )
Use this:
mysqli_query($this->db_link, $query) or die(mysqli_error($this->db_link));
# mysqli_query($link,$query) returns 0 if there's an error.
# mysqli_error($link) returns a string with the last error message
You can also use this to print the error code.
echo mysqli_errno($this->db_link);
could you not just keep a running index?
var _selectIndex = 0;
...code...
var newSelectBox = document.createElement("select");
newSelectBox.setAttribute("id","select-"+_selectIndex++);
EDIT
Upon further consideration, you may actually prefer to use array-style names for your selects...
e.g.
<select name="city[]"><option ..../></select>
<select name="city[]"><option ..../></select>
<select name="city[]"><option ..../></select>
then, on the server side in php for example:
$cities = $_POST['city']; //array of option values from selects
EDIT 2 In response to OP comment
Dynamically creating options using DOM methods can be done as follows:
var newSelectBox = document.createElement("select");
newSelectBox.setAttribute("id","select-"+_selectIndex++);
var city = null,city_opt=null;
for (var i=0, len=cities.length; i< len; i++) {
city = cities[i];
var city_opt = document.createElement("option");
city_opt.setAttribute("value",city);
city_opt.appendChild(document.createTextNode(city));
newSelectBox.appendChild(city_opt);
}
document.getElementById("example_element").appendChild(newSelectBox);
assuming that the cities
array already exists
Alternatively you could use the innerHTML method.....
var newSelectBox = document.createElement("select");
newSelectBox.setAttribute("id","select-"+_selectIndex++);
document.getElementById("example_element").appendChild(newSelectBox);
var city = null,htmlStr="";
for (var i=0, len=cities.length; i< len; i++) {
city = cities[i];
htmlStr += "<option value='" + city + "'>" + city + "</option>";
}
newSelectBox.innerHTML = htmlStr;
I love extensions when they make the code cleaner:
extension NSUserDefaults {
func clear() {
guard let domainName = NSBundle.mainBundle().bundleIdentifier else {
return
}
self.removePersistentDomainForName(domainName)
}
}
Swift 5
extension UserDefaults {
func clear() {
guard let domainName = Bundle.main.bundleIdentifier else {
return
}
removePersistentDomain(forName: domainName)
synchronize()
}
}
//for update
(from x in dataBase.Customers
where x.Name == "Test"
select x).ToList().ForEach(xx => xx.Name="New Name");
//for delete
dataBase.Customers.RemoveAll(x=>x.Name=="Name");
In Kotlin, if
statements are expressions. So the following code is equivalent:
if (a) b else c
The distinction between expression and statement is important here. In Java/C#/JavaScript, if
forms a statement, meaning that it does not resolve to a value. More concretely, you can't assign it to a variable.
// Valid Kotlin, but invalid Java/C#/JavaScript
var v = if (a) b else c
If you're coming from a language where if
is a statement, this might seem unnatural but that feeling should soon subside.
Try this:
<input type="text" placeholder="some text" class="search" onkeydown="search(this)"/>
<input type="text" placeholder="some text" class="search" onkeydown="search(this)"/>
JS Code
function search(ele) {
if(event.key === 'Enter') {
alert(ele.value);
}
}
If you still want to show the item but make it not clickable and look disabled with CSS:
CSS:
.disabled {
pointer-events:none; //This makes it not clickable
opacity:0.6; //This grays it out to look disabled
}
HTML:
<li class="disabled">Disabled List Item</li>
Also, if you are using BootStrap, they already have a class called disabled for this purpose. See this example.
As @LV98 pointed out, users could change this on the client side and submit a selection you weren't expecting. You will want to validate at the server as well.
Cheap and cheerful answer:
<textarea>Some raw content</textarea>
The textarea will handle tabs, multiple spaces, newlines, line wrapping all verbatim. It copies and pastes nicely and its valid HTML all the way. It also allows the user to resize the code box. You don't need any CSS, JS, escaping, encoding.
You can alter the appearance and behaviour as well. Here's a monospace font, editing disabled, smaller font, no border:
<textarea
style="width:100%; font-family: Monospace; font-size:10px; border:0;"
rows="30" disabled
>Some raw content</textarea>
This solution is probably not semantically correct. So if you need that, it might be best to choose a more sophisticated answer.
SELECT * FROM a WHERE a.group_id IN
(SELECT group_id FROM b WHERE b.user_id!=$_SESSION{'[user_id']} AND b.group_id = a.group_id)
WHERE a.keyword LIKE '%".$keyword."%';
put these in values/colors.xml
<resources>
<color name="light_font">#FBFBFB</color>
<color name="grey_font">#ff9e9e9e</color>
<color name="text_shadow">#7F000000</color>
<color name="text_shadow_white">#FFFFFF</color>
</resources>
Then in your layout xml here are some example TextView's
Example of Floating text on Light with Dark shadow
<TextView android:id="@+id/txt_example1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textSize="14sp"
android:textStyle="bold"
android:textColor="@color/light_font"
android:shadowColor="@color/text_shadow"
android:shadowDx="1"
android:shadowDy="1"
android:shadowRadius="2" />
Example of Etched text on Light with Dark shadow
<TextView android:id="@+id/txt_example2"

android:textSize="14sp"
android:textStyle="bold"
android:textColor="@color/light_font"
android:shadowColor="@color/text_shadow"
android:shadowDx="-1"
android:shadowDy="-1"
android:shadowRadius="1" />
Example of Crisp text on Light with Dark shadow
<TextView android:id="@+id/txt_example3"
android:layout_width="wrap_content"
android:layout_height="wrap_content"

android:textColor="@color/grey_font"
android:shadowColor="@color/text_shadow_white"
android:shadowDx="-2"
android:shadowDy="-2"
android:shadowRadius="1" />
Notice the positive and negative values... I suggest to play around with the colors/values yourself but ultimately you can adjust these settings to get the effect your looking for.
It varies on implementation and version, but usually it depends on the VM used (e.g. client or server, see -client
and -server
parameters) and on your system memory.
Often for client
the default value is 1/4th of your physical memory or 1GB (whichever is smaller).
Also Java configuration options (command line parameters) can be "outsourced" to environment variables including the -Xmx
, which can change the default (meaning specify a new default). Specifically the JAVA_TOOL_OPTIONS
environment variable is checked by all Java tools and used if exists (more details here and here).
You can run the following command to see default values:
java -XX:+PrintFlagsFinal -version
It gives you a loooong list, -Xmx
is in MaxHeapSize
, -Xms
is in InitialHeapSize
. Filter your output (e.g. |grep
on linux) or save it in a file so you can search in it.
If you're on .NET 3.5 or up, you can use the new System.DirectoryServices.AccountManagement
(S.DS.AM) namespace which makes this a lot easier than it used to be.
Read all about it here: Managing Directory Security Principals in the .NET Framework 3.5
Update: older MSDN magazine articles aren't online anymore, unfortunately - you'll need to download the CHM for the January 2008 MSDN magazine from Microsoft and read the article in there.
Basically, you need to have a "principal context" (typically your domain), a user principal, and then you get its groups very easily:
public List<GroupPrincipal> GetGroups(string userName)
{
List<GroupPrincipal> result = new List<GroupPrincipal>();
// establish domain context
PrincipalContext yourDomain = new PrincipalContext(ContextType.Domain);
// find your user
UserPrincipal user = UserPrincipal.FindByIdentity(yourDomain, userName);
// if found - grab its groups
if(user != null)
{
PrincipalSearchResult<Principal> groups = user.GetAuthorizationGroups();
// iterate over all groups
foreach(Principal p in groups)
{
// make sure to add only group principals
if(p is GroupPrincipal)
{
result.Add((GroupPrincipal)p);
}
}
}
return result;
}
and that's all there is! You now have a result (a list) of authorization groups that user belongs to - iterate over them, print out their names or whatever you need to do.
Update: In order to access certain properties, which are not surfaced on the UserPrincipal
object, you need to dig into the underlying DirectoryEntry
:
public string GetDepartment(Principal principal)
{
string result = string.Empty;
DirectoryEntry de = (principal.GetUnderlyingObject() as DirectoryEntry);
if (de != null)
{
if (de.Properties.Contains("department"))
{
result = de.Properties["department"][0].ToString();
}
}
return result;
}
Update #2: seems shouldn't be too hard to put these two snippets of code together.... but ok - here it goes:
public string GetDepartment(string username)
{
string result = string.Empty;
// if you do repeated domain access, you might want to do this *once* outside this method,
// and pass it in as a second parameter!
PrincipalContext yourDomain = new PrincipalContext(ContextType.Domain);
// find the user
UserPrincipal user = UserPrincipal.FindByIdentity(yourDomain, username);
// if user is found
if(user != null)
{
// get DirectoryEntry underlying it
DirectoryEntry de = (user.GetUnderlyingObject() as DirectoryEntry);
if (de != null)
{
if (de.Properties.Contains("department"))
{
result = de.Properties["department"][0].ToString();
}
}
}
return result;
}
Use "javascript.validate.enable": false
in your VS Code settings, It doesn't disable ESLINT. I use both ESLINT & Flow. Simply follow the instructions Flow For Vs Code Setup
Adding this line in settings.json. Helps
"javascript.validate.enable": false
If you want to have a different icon for each list-item, I suggest adding icons in HTML instead of using a pseudo element to keep your CSS down. It can be done quite simply as follows:
<ul>
<li><span><i class="mdi mdi-lightbulb-outline"></i></span>An electric light with a wire filament heated to such a high temperature that it glows with visible light</li>
<li><span><i class="mdi mdi-clipboard-check-outline"></i></span>A thin, rigid board with a clip at the top for holding paper in place.</li>
<li><span><i class="mdi mdi-finance"></i></span>A graphical representation of data, in which the data is represented by symbols, such as bars in a bar chart, lines in a line chart, or slices in a pie chart.</li>
<li><span><i class="mdi mdi-server"></i></span>A system that responds to requests across a computer network worldwide to provide, or help to provide, a network or data service.</li>
</ul>
-
ul {
list-style-type: none;
margin-left: 2.5em;
padding-left: 0;
}
ul>li {
position: relative;
}
span {
left: -2em;
position: absolute;
text-align: center;
width: 2em;
line-height: inherit;
}
In this case I used Material Design Icons
In the AVD setup: Change the CPU/ABI option to MIPS. It worked for me
I had a simular issue and resolved it using android:adjustViewBounds="true"
on the ImageView.
<ImageView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:adjustViewBounds="true"
android:contentDescription="@string/banner_alt"
android:src="@drawable/banner_portrait" />
Try this,
$('td').click(function(){
var row_index = $(this).parent().index();
var col_index = $(this).index();
});
If you need the index of table contain td then you can change it to
var row_index = $(this).parent('table').index();
You can even add the size of the terms (indexed terms). Have a look at Elastic Search: how to see the indexed data
This seems to be the issue:
An input that is received via Ajax websocket etc, and it will be in String format, but you need to know if it is JSON.parsable
. The touble is, if you always run it through JSON.parse
, the program MAY continue "successfully" but you'll still see an error thrown in the console with the dreaded "Error: unexpected token 'x'"
.
var data;
try {
data = JSON.parse(jqxhr.responseText);
} catch (_error) {}
data || (data = {
message: 'Server error, please retry'
});
Just as an FYI....
select * from sys.types where system_type_id = 231
gives you two rows.
(i'm not sure what this means yet but i'm 100% sure it's messing up my code right now)
edit: i guess what it means is that you should join by the user_type_id in this situation (my situation) or possibly both the user_type_id and the system_type_id
name system_type_id user_type_id schema_id principal_id max_length precision scale collation_name is_nullable is_user_defined is_assembly_type default_object_id rule_object_id

This query:
select parm.name AS Parameter,
parm.max_length,
parm.parameter_id
from sys.procedures sp
join sys.parameters parm ON sp.object_id = parm.object_id

@col_three 2 3
@col_four 2 4
@col_five 256 5
@col_six 256 6

Append .done()
to your ajax request.
$.ajax({
url: "test.html",
context: document.body
}).done(function() { //use this
alert("DONE!");
});
See the JQuery Doc for .done()
Also when you call from http request it will work properly but when your try to call from net.tcp that time you get all this kind stuff
You basically put the files you want to commit on the command line
svn ci file1 file2 dir1/file3
When I need to write new lines a lot, I define a lambda that uses a print
function:
out = open(file_name, 'w')
fwl = lambda *x, **y: print(*x, **y, file=out) # FileWriteLine
fwl('Hi')
This approach has the benefit that it can utilize all the features that are available with the print
function.
Update: As is mentioned by Georgy in the comment section, it is possible to improve this idea further with the partial
function:
from functools import partial
fwl = partial(print, file=out)
IMHO, this is a more functional and less cryptic approach.
You can get the second method to achieve the same effect by:
var mySecondDiv = $('<div></div>');
$(mySecondDiv).find('div').attr('id', 'mySecondDiv');
$('#myDiv').append(mySecondDiv);
Luca mentioned that html()
just inserts hte HTML which results in faster performance.
In some occassions though, you would opt for the second option, consider:
// Clumsy string concat, error prone
$('#myDiv').html("<div style='width:'" + myWidth + "'px'>Lorem ipsum</div>");
// Isn't this a lot cleaner? (though longer)
var newDiv = $('<div></div>');
$(newDiv).find('div').css('width', myWidth);
$('#myDiv').append(newDiv);
For compression, I would use a library (7-Zip is good like Michal suggests).
If you install 7-Zip, the installed directory will contain 7z.exe
which is a console application.
You can invoke it directly and use any compression option you want.
If you wish to engage with the DLL, that should also be possible.
7-Zip is freeware and open source.
You can use the rather sensibly named xpath function called concat here
<a>
<xsl:attribute name="href">
<xsl:value-of select="concat('myText:', /*/properties/property[@name='report']/@value)" />
</xsl:attribute>
</a>
Of course, it doesn't have to be text here, it can be another xpath expression to select an element or attribute. And you can have any number of arguments in the concat expression.
Do note, you can make use of Attribute Value Templates (represented by the curly braces) here to simplify your expression
<a href="{concat('myText:', /*/properties/property[@name='report']/@value)}"></a>
The gap between the (bootstrap) input field and jquery-ui autocompleter seem to occur only in jQuery versions >= 3.2
When using jQuery version 3.1.1 it seem to not happen.
Possible reason is the notable update in v3.2.0 related to a bug fix on .width()
and .height()
. Check out the jQuery release notes for further details: v3.2.0 / v3.1.1
Bootstrap version 3.4.1 and jquery-ui version 1.12.0 used

<div id="nav-main" class="nav-collapse collapse">
<ul class="nav">

</li>
</ul>
</div>
on nav toggle 'in' class is added and removed from the toggle. check if responsive menu is opened then perform the close toggle.
$('.nav-collapse .nav a').on('click', function(){
if ( $( '.nav-collapse' ).hasClass('in') ) {
$('.navbar-toggle').click();
}
});
Is there a way to apply a Class' style to only ONE level of td tags?
Yes*:
.MyClass>tbody>tr>td { border: solid 1px red; }
But! The ‘>
’ direct-child selector does not work in IE6. If you need to support that browser (which you probably do, alas), all you can do is select the inner element separately and un-set the style:
.MyClass td { border: solid 1px red; }
.MyClass td td { border: none; }
*Note that the first example references a tbody
element not found in your HTML. It should have been in your HTML, but browsers are generally ok with leaving it out... they just add it in behind the scenes.
Another way to remove the "save image" context menu is to use some CSS. This also leaves the rest of the context-menu intact.
img {
pointer-events: none;
}
It makes all img
elements non-reactive to any mouse events such as dragging, hovering, clicking etc.
See spec for more info.
Interfaces can not contain any implementation (including default values). You need to switch to abstract class.
There is no automated uninstaller.
You have to remove Eclipse manually. At least Eclipse does not write anything in the system registry, so deleting some directories and files is enough.
Note: I use Unix style paths in this answer but the locations should be the same on Windows or Unix systems, so ~
refers to the user home directory even on Windows.
According to this discussion about uninstalling Eclipse, the reasoning for not providing an uninstaller is that the Eclipse installer is supposed to just automate a few tasks that in the past had to be done manually (like downloading and extracting Eclipse and adding shortcuts), so they also can be undone manually. There is no entry in "Programs and Features" because the installer does not register anything in the system registry.
Just delete the Eclipse directory and any desktop and start menu shortcuts and be done with it, if you don't mind a few leftover files.
In my opinion this is generally enough and I would stop here, because multiple Eclipse installations can share some files and you don't accidentally want to delete those shared files. You also keep all your projects.
If you really want to remove Eclipse without leaving any traces, you have to manually delete
~/eclipse/photon/
)The installer has a "Bundle Pools" menu entry which lists the locations of all bundle pools. If you have other Eclipse installations on your system you can use the "Cleanup Agent" to clean up unused bundles. If you don't have any other Eclipse installations you can delete the whole bundle pool directory instead (by default ~/p2/
).
If you want to completely remove the Eclipse installer too, delete the installer's executable and the ~/.eclipse/
directory.
Depending on what kind of work you did with Eclipse, there can be more directories that you may want to delete. If you used Maven, then ~/.m2/
contains the Maven cache and settings (shared with Maven CLI and other IDEs). If you develop Eclipse plugins, then there might be JUnit workspaces from test runs, next to you Eclipse workspace. Likewise other build tools and development environments used in Eclipse could have created similar directories.
If you want to delete your projects and workspace metadata, you have to delete your workspace(s). The default workspace location is ´~/workspace/´. You can also search for the .metadata
directory to get all Eclipse workspaces on your machine.
If you are working with Git projects, these are generally not saved in the workspace but in the ~/git/
directory.
I found this library to work when MarcJ's solution didn't:
https://github.com/sdecima/javascript-detect-element-resize
It's very lightweight and detects even natural resizes via CSS or simply the HTML loading/rendering.
Code sample (taken from the link):
<script type="text/javascript" src="detect-element-resize.js"></script>
<script type="text/javascript">
var resizeElement = document.getElementById('resizeElement'),
resizeCallback = function() {
/* do something */
};
addResizeListener(resizeElement, resizeCallback);
removeResizeListener(resizeElement, resizeCallback);
</script>
I'm assuming you're using jquery to make the AJAX call so you can do this pretty easily by putting the redirect in the success like so:
$.ajax({
url: 'ajax_location.html',
success: function(data) {
//this is the redirect
document.location.href='/newpage/';
}
});
Use element.classList
.contains
method:
element.classList.contains(class);
This works on all current browsers and there are polyfills to support older browsers too.
Alternatively, if you work with older browsers and don't want to use polyfills to fix them, using indexOf
is correct, but you have to tweak it a little:
function hasClass(element, className) {
return (' ' + element.className + ' ').indexOf(' ' + className+ ' ') > -1;
}
Otherwise you will also get true
if the class you are looking for is part of another class name.
jQuery uses a similar (if not the same) method.
Applied to the example:
As this does not work together with the switch statement, you could achieve the same effect with this code:
var test = document.getElementById("test"),
classes = ['class1', 'class2', 'class3', 'class4'];
test.innerHTML = "";
for(var i = 0, j = classes.length; i < j; i++) {
if(hasClass(test, classes[i])) {
test.innerHTML = "I have " + classes[i];
break;
}
}
It's also less redundant ;)
Please use json.Decoder

if err != nil {
panic(err)
}
log.Println(t.Test)

I want to change the width and height of a div. data attributes did not change it. Instead I use:
var size = $("#theme_photo_size").val().split("x");
$("#imageupload_img").width(size[0]);
$("#imageupload_img").attr("data-width", size[0]);
$("#imageupload_img").height(size[1]);
$("#imageupload_img").attr("data-height", size[1]);
be careful:
$("#imageupload_img").data("height", size[1]); //did not work
did not set it
$("#imageupload_img").attr("data-height", size[1]); // yes it worked!
this has set it.
Looks like Microsoft knows accept-charset, but their doc doesn't tell for which version it starts to work...
You don't tell either in which versions of browser you tested it.
SLaks hit the nail on the head but you might want to look over the changes for inputs in CSS3 in general. Rounded corners and box-shadow are both new features in CSS3 and will let you do exactly what you're looking for. One of my personal favorite links for CSS3/HTML5 is http://diveintohtml5.ep.io/ .

), header=TRUE)
R> table(x$Believe)
FALSE TRUE

I know I'm late to the party, but I thought if after trying the accepted answer by @Glenn Slaven and the current highest rated answer by @Espo you are still out of luck, the following might save some people out there some trouble.
User Controls (.ascx) are what constantly stop auto-generating for me. I've found that in the instances where I use other User Control(s) in my User Control, it breaks the auto-generation.
The solution I came up with was to use the trick we all know of for getting IntelliSense to work in User Controls or Skin files when using CSS classes from external sources. Instead of just referencing the CSS file, now I Register the other User Control(s) that I need. It looks something like this:
<% If False Then %>
<%@ Register TagPrefix="uc" TagName="Title" Src="~/controls/title.ascx" %>
<link rel="stylesheet" type="text/css" href="../css/common.css" />
<% End If %>
After that, I Save the file, which prompts the auto-generation to regenerate, and I'm back up and running.
My code, efficient without tables or additional variables:
SELECT
((SUBSTRING_INDEX(SUBSTRING_INDEX(group_concat(val order by val), ',', floor(1+((count(val)-1) / 2))), ',', -1))
+
(SUBSTRING_INDEX(SUBSTRING_INDEX(group_concat(val order by val), ',', ceiling(1+((count(val)-1) / 2))), ',', -1)))/2
as median
FROM table;
