The read
in your script command is fine. However, you execute it in the pipeline, which means it is in a subshell, therefore, the variables it reads to are not visible in the parent shell. You can either
move the rest of the script in the subshell, too:
echo hello | { read str
echo $str
}
or use command substitution to get the value of the variable out of the subshell
str=$(echo hello)
echo $str
or a slightly more complicated example (Grabbing the 2nd element of ls)
str=$(ls | { read a; read a; echo $a; })
echo $str
$data_arr = array('hello', 'developer', 'laravel' );
// We Have to remove Value "hello" from the array
// Check if the value is exists in the array
if (array_search('hello', $data_arr ) !== false) {
$key = array_search('hello', $data_arr );
unset( $data_arr[$key] );
}
# output:
// It will Return unsorted Indexed array
print( $data_arr )
// To Sort Array index use this
$data_arr = array_values( $data_arr );
// Now the array key is sorted
I prefer the answers a and b above using functools.reduce() and the answer using numpy.prod(), but here is yet another solution using itertools.accumulate():
import itertools
import operator
prod = list(itertools.accumulate((3, 4, 5), operator.mul))[-1]
A useful application for : is if you're only interested in using parameter expansions for their side-effects rather than actually passing their result to a command. In that case you use the PE as an argument to either : or false depending upon whether you want an exit status of 0 or 1. An example might be : "${var:=$1}"
. Since :
is a builtin it should be pretty fast.
If you've got ther JSON data coming in as a string (e.g. '[{"id":1,"name":"Charles"},{"id":8,"name":"John"},{"id":13,"name":"Sally"}]')
Then I'd use JSON.net and use Linq to JSON to get the values out...
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using Newtonsoft.Json;
using Newtonsoft.Json.Linq;
public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
if (Request["items"] != null)
{
var items = Request["items"].ToString(); // Get the JSON string
JArray o = JArray.Parse(items); // It is an array so parse into a JArray
var a = o.SelectToken("[0].name").ToString(); // Get the name value of the 1st object in the array
// a == "Charles"
}
}
}
You can query the ALL_OBJECTS view:
select owner
, object_name
, object_type
from ALL_OBJECTS
where object_name = 'FOO'
To find synonyms:
select *
from ALL_SYNONYMS
where synonym_name = 'FOO'
Just to clarify, if a user user's SQL statement references an object name with no schema qualification (e.g. 'FOO'), Oracle FIRST checks the user's schema for an object of that name (including synonyms in that user's schema). If Oracle can't resolve the reference from the user's schema, Oracle then checks for a public synonym.
If you are looking specifically for constraints on a particular table_name:
select c.*
from all_constraints c
where c.table_name = 'FOO'
union all
select cs.*
from all_constraints cs
join all_synonyms s
on (s.table_name = cs.table_name
and s.table_owner = cs.owner
and s.synonym_name = 'FOO'
)
HTH
-- addendum:
If your user is granted access to the DBA_ views (e.g. if your user has been granted SELECT_CATALOG_ROLE), you can substitute 'DBA_
' in place of 'ALL_
' in the preceding SQL examples. The ALL_x
views only show objects which you have been granted privileges. The DBA_x
views will show all database objects, whether you have privileges on them or not.
Yes, it's possible to To capture div as PDFs in JS. You can can check the solution provided by https://grabz.it. They have nice and clean JavaScript API which will allow you to capture the content of a single HTML element such as a div or a span.
So, yo use it you will need and app+key and the free SDK. The usage of it is as following:
Let's say you have a HTML:
<div id="features">
<h4>Acme Camera</h4>
<label>Price</label>$399<br />
<label>Rating</label>4.5 out of 5
</div>
<p>Cras ut velit sed purus porttitor aliquam. Nulla tristique magna ac libero tempor, ac vestibulum felisvulput ate. Nam ut velit eget
risus porttitor tristique at ac diam. Sed nisi risus, rutrum a metus suscipit, euismod tristique nulla. Etiam venenatis rutrum risus at
blandit. In hac habitasse platea dictumst. Suspendisse potenti. Phasellus eget vehicula felis.</p>
To capture what is under the features id you will need to:
//add the sdk
<script type="text/javascript" src="grabzit.min.js"></script>
<script type="text/javascript">
//login with your key and secret.
GrabzIt("KEY", "SECRET").ConvertURL("http://www.example.com/my-page.html",
{"target": "#features", "format": "pdf"}).Create();
</script>
You need to replace the http://www.example.com/my-page.html
with your target url and #feature
per your CSS selector.
That's all. Now, when the page is loaded an image screenshot will now be created in the same location as the script tag, which will contain all of the contents of the features div and nothing else.
The are other configuration and customization you can do to the div-screenshot mechanism, please check them out here
The java design of the "enhanced for loop" was to not expose the iterator to code, but the only way to safely remove an item is to access the iterator. So in this case you have to do it old school:
for(Iterator<String> i = names.iterator(); i.hasNext();) {
String name = i.next();
//Do Something
i.remove();
}
If in the real code the enhanced for loop is really worth it, then you could add the items to a temporary collection and call removeAll on the list after the loop.
EDIT (re addendum): No, changing the list in any way outside the iterator.remove() method while iterating will cause problems. The only way around this is to use a CopyOnWriteArrayList, but that is really intended for concurrency issues.
The cheapest (in terms of lines of code) way to remove duplicates is to dump the list into a LinkedHashSet (and then back into a List if you need). This preserves insertion order while removing duplicates.
Rebuilding the slave using LVM
Here is the method we use to rebuild MySQL slaves using Linux LVM. This guarantees a consistent snapshot while requiring very minimal downtime on your master.
Set innodb max dirty pages percent to zero on the master MySQL server. This will force MySQL to write all the pages to the disk which will significantly speed up the restart.
set global innodb_max_dirty_pages_pct = 0;
To monitor the number of dirty pages run the command
mysqladmin ext -i10 | grep dirty
Once the number stop decreasing you have reach the point to continue. Next reset the master to clear the old bin logs / relay logs:
RESET MASTER;
Execute lvdisplay to get LV Path
lvdisplay
Output will look like this
--- Logical volume ---
LV Path /dev/vg_mysql/lv_data
LV Name lv_data
VG Name vg_mysql
Shutdown the master database with command
service mysql stop
Next take a snaphot, mysql_snapshot will be the new logical volume name. If binlogs are place on the OS drive those need to be snapshot as well.
lvcreate --size 10G --snapshot --name mysql_snapshot /dev/vg_mysql/lv_data
Start master again with command
service mysql start
Restore dirty pages setting to the default
set global innodb_max_dirty_pages_pct = 75;
Run lvdisplay again to make sure the snapshot is there and visible
lvdisplay
Output:
--- Logical volume ---
LV Path /dev/vg_mysql/mysql_snapshot
LV Name mysql_snapshot
VG Name vg_mysql
Mount the snapshot
mkdir /mnt/mysql_snapshot
mount /dev/vg_mysql/mysql_snapshot /mnt/mysql_snapshot
If you have an existing MySQL slave running you need to stop it
service mysql stop
Next you need to clear MySQL data folder
cd /var/lib/mysql
rm -fr *
Back to master. Now rsync the snapshot to the MySQL slave
rsync --progress -harz /mnt/mysql_snapshot/ targethostname:/var/lib/mysql/
Once rsync has completed you may unmount and remove the snapshot
umount /mnt/mysql_snapshot
lvremove -f /dev/vg_mysql/mysql_snapshot
Create replication user on the master if the old replication user doesn't exist or password is unknown
GRANT REPLICATION SLAVE on *.* to 'replication'@'[SLAVE IP]' identified by 'YourPass';
Verify that /var/lib/mysql data files are owned by the mysql user, if so you can omit the following command:
chown -R mysql:mysql /var/lib/mysql
Next record the binlog position
ls -laF | grep mysql-bin
You will see something like
..
-rw-rw---- 1 mysql mysql 1073750329 Aug 28 03:33 mysql-bin.000017
-rw-rw---- 1 mysql mysql 1073741932 Aug 28 08:32 mysql-bin.000018
-rw-rw---- 1 mysql mysql 963333441 Aug 28 15:37 mysql-bin.000019
-rw-rw---- 1 mysql mysql 65657162 Aug 28 16:44 mysql-bin.000020
Here the master log file is the highest file number in sequence and bin log position is the file size. Record these values:
master_log_file=mysql-bin.000020
master_log_post=65657162
Next start the slave MySQL
service mysql start
Execute change master command on the slave by executing the following:
CHANGE MASTER TO
master_host="10.0.0.12",
master_user="replication",
master_password="YourPass",
master_log_file="mysql-bin.000020",
master_log_pos=65657162;
Finally start the slave
SLAVE START;
Check slave status:
SHOW SLAVE STATUS;
Make sure Slave IO is running and there are no connection errors. Good luck!

If you have Pillow
installed with scipy
and it is still giving you error then check your scipy
version because it has been removed from scipy since 1.3.0rc1
.
rather install scipy 1.1.0
by :
pip install scipy==1.1.0
check https://github.com/scipy/scipy/issues/6212
The method imread
in scipy.misc
requires the forked package of PIL
named Pillow
. If you are having problem installing the right version of PIL try using imread
in other packages:
from matplotlib.pyplot import imread
im = imread(image.png)
To read jpg
images without PIL
use:
import cv2 as cv
im = cv.imread(image.jpg)
You can try
from scipy.misc.pilutil import imread
instead of from scipy.misc import imread
Please check the GitHub page : https://github.com/amueller/mglearn/issues/2 for more details.
string ip = ((IPEndPoint)(testsocket.RemoteEndPoint)).Address.ToString();
I've had this problem before, you can go to "advanced" tab of "choose a data source" page and click on "suggested types" button, and set the "number of rows" as much as you want. after that, the type and text qualified are set to the true values.
i applied the above solution and can convert my data to SQL.
Neither on SQL2005 nor 2012 does DBCC USEROPTIONS
show is_read_committed_snapshot_on
:
Set Option Value
textsize 2147483647
language us_english
dateformat mdy
datefirst 7
lock_timeout -1
quoted_identifier SET
arithabort SET
ansi_null_dflt_on SET
ansi_warnings SET
ansi_padding SET
ansi_nulls SET
concat_null_yields_null SET
isolation level read committed
Long story short: Don't use FileInputStream as a parameter or variable type. Use the abstract base class, in this case InputStream instead.
You would first remove the table, then add the new replacement to the table's parent object.
Look up removeChild
and appendChild
http://javascript.about.com/library/bldom09.htm
https://developer.mozilla.org/en-US/docs/DOM/Node.appendChild
Edit: jQuery .append allows sting-html without removing tags: http://api.jquery.com/append/
Since R is already installed, you should be able to upgrade it with this method. First of all, you may want to have the packages you installed in the previous version in the new one,so it is convenient to check this post. Then, follow the instructions from here
Open the sources.list
file:
sudo nano /etc/apt/sources.list
Add a line with the source from where the packages will be retrieved. For example:
deb https://cloud.r-project.org/bin/linux/ubuntu/ version/
Replace https://cloud.r-project.org
with whatever mirror you would like to use, and replace
version/
with whatever version of Ubuntu you are using (eg, trusty/
, xenial/
, and so on). If you're getting a "Malformed line error", check to see if you have a space between /ubuntu/
and version/
.
Fetch the secure APT key:
gpg --keyserver keyserver.ubuntu.com --recv-key E298A3A825C0D65DFD57CBB651716619E084DAB9
or
gpg --hkp://keyserver keyserver.ubuntu.com:80 --recv-key E298A3A825C0D65DFD57CBB651716619E084DAB9
Add it to keyring:
gpg -a --export E084DAB9 | sudo apt-key add -
Update your sources and upgrade your installation:
sudo apt-get update && sudo apt-get upgrade
Install the new version
sudo apt-get install r-base-dev
Recover your old packages following the solution that best suits to you (see this). For instance, to recover all the packages (not only those from CRAN) the idea is:
-- copy the packages from R-oldversion/library
to R-newversion/library
, (do not overwrite a package if it already exists in the new version!).
-- Run the R command update.packages(checkBuilt=TRUE, ask=FALSE)
.
&
is a character; &
is a HTML character entity for that character.
<br>
is an element. Elements don't get character entities.
In contrast to many answers here, \n
or
are not equivalent to <br>
. The former denotes a line break in text documents. The latter is intended to denote a line break in HTML documents and is doing that by virtue of its default CSS:
br:before { content: "\A"; white-space: pre-line }
A textual line break can be rendered as an HTML line break or can be treated as whitespace, depending on the CSS white-space
property.
Although @amr ali's code was great, I had an instance where my bat file contained >

For ASP.NET Core You can use asp-route-* attribute:
<form asp-action="Login" asp-route-previous="@Model.ReturnUrl">
An example: Imagine that you have a Vehicle Controller with actions
Index
Details
Edit
and you can edit any vehicle from Index or from Details, so if you clicked edit from index you must return to index after edit and if you clicked edit from details you must return to details after edit.
//In your viewmodel add the ReturnUrl Property
public class VehicleViewModel
{
..............
..............
public string ReturnUrl {get;set;}
}
Details.cshtml
<a asp-action="Edit" asp-route-previous="Details" asp-route-id="@Model.CarId">Edit</a>
Index.cshtml
<a asp-action="Edit" asp-route-previous="Index" asp-route-id="@item.CarId">Edit</a>
Edit.cshtml
<form asp-action="Edit" asp-route-previous="@Model.ReturnUrl" class="form-horizontal">
<div class="box-footer">
<a asp-action="@Model.ReturnUrl" class="btn btn-default">Back to List</a>
<button type="submit" value="Save" class="btn btn-warning pull-right">Save</button>
</div>
</form>
In your controller:
// GET: Vehicle/Edit/5
public ActionResult Edit(int id,string previous)
{
var model = this.UnitOfWork.CarsRepository.GetAllByCarId(id).FirstOrDefault();
var viewModel = this.Mapper.Map<VehicleViewModel>(model);//if you using automapper
//or by this code if you are not use automapper
var viewModel = new VehicleViewModel();
if (!string.IsNullOrWhiteSpace(previous)
viewModel.ReturnUrl = previous;
else
viewModel.ReturnUrl = "Index";
return View(viewModel);
}
[HttpPost]
public IActionResult Edit(VehicleViewModel model, string previous)
{
if (!string.IsNullOrWhiteSpace(previous))
model.ReturnUrl = previous;
else
model.ReturnUrl = "Index";
.............
.............
return RedirectToAction(model.ReturnUrl);
}
You need to follow the GitHub API. See the documentation here for all the details regarding your repository. It requires you to make a GET request as:
GET /repos/:owner/:repository
You need to replace two things:
E.g., my username maheshmnj, and I own a repository, flutter-ui-nice, so my GET URL will be:
https://api.github.com/repos/maheshmnj/flutter-ui-nice
On making a GET request, you will be flooded with some JSON data and probably on line number 78 you should see a key named size that will return the size of the repository.
Tip: When working with JSON I suggest you to add a plugin that formats the JSON data to make reading JSON easy. Install the plugin.
#include <typeinfo>
...
string s = typeid(YourClass).name()
Eval is used to bind to an UI item that is setup to be read-only (eg: a label or a read-only text box), i.e., Eval is used for one way binding - for reading from a database into a UI field.
It is generally used for late-bound data (not known from start) and usually bound to the smallest part of the data-bound control that contains a whole record. The Eval method takes the name of a data field and returns a string containing the value of that field from the current record in the data source. You can supply an optional second parameter to specify a format for the returned string. The string format parameter uses the syntax defined for the Format method of the String class.
Using Spring's StringUtils
:
org.springframework.util.StringUtils.capitalize(someText);
If you're already using Spring anyway, this avoids bringing in another framework.
You can also do it in one row:
if (MessageBox.Show("Text", "Title", MessageBoxButtons.YesNo) == DialogResult.Yes)
And if you want to show a messagebox on top:
if (MessageBox.Show(new Form() { TopMost = true }, "Text", "Text", MessageBoxButtons.YesNo) == DialogResult.Yes)
From the matplotlib docs on scatter 1:
cmap is only used if c is an array of floats
So colorlist needs to be a list of floats rather than a list of tuples as you have it now. plt.colorbar() wants a mappable object, like the CircleCollection that plt.scatter() returns. vmin and vmax can then control the limits of your colorbar. Things outside vmin/vmax get the colors of the endpoints.
How does this work for you?
import matplotlib.pyplot as plt
cm = plt.cm.get_cmap('RdYlBu')
xy = range(20)
z = xy
sc = plt.scatter(xy, xy, c=z, vmin=0, vmax=20, s=35, cmap=cm)
plt.colorbar(sc)
plt.show()
MiniConnectionPoolManager
is a one-java-file implementation, if you're looking for an embeddable solution and are not too concerned about performances (though I haven't tested it in that regard).
It is multi-licensed EPL, LGPL and MPL.
Its documentation also gives alternatives worth checking (on top of DBCP and C3P0):
Since hashes aren't inherently ordered, there isn't a notion of appending. Ruby hashes since 1.9 maintain insertion order, however. Here are the ways to add new key/value pairs.
The simplest solution is
h[:key] = "bar"
If you want a method, use store
:
h.store(:key, "bar")
If you really, really want to use a "shovel" operator (<<
), it is actually appending to the value of the hash as an array, and you must specify the key:
h[:key] << "bar"
The above only works when the key exists. To append a new key, you have to initialize the hash with a default value, which you can do like this:
h = Hash.new {|h, k| h[k] = ''}
h[:key] << "bar"
You may be tempted to monkey patch Hash to include a shovel operator that works in the way you've written:
class Hash
def <<(k,v)
self.store(k,v)
end
end
However, this doesn't inherit the "syntactic sugar" applied to the shovel operator in other contexts:
h << :key, "bar" #doesn't work
h.<< :key, "bar" #works

});
});
The return
exits the current function, but the iterations keeps on, so you get the "next" item that skips the if
and alerts the 4...
If you need to stop the looping, you should just use a plain for
loop like so:
$('button').click(function () {
var arr = [1, 2, 3, 4, 5];
for(var i = 0; i < arr.length; i++) {
var n = arr[i];
if (n == 3) {
break;
}
alert(n);
})
})

The simplest approach that I have implemented is to use Date() itself. `
const days = 15;
// Date.now() gives the epoch date value (in milliseconds) of current date
nextDate = new Date( Date.now() + days * 24 * 60 * 60 * 1000)
`
You can use this function:
UIImageWriteToSavedPhotosAlbum(UIImage *image,
id completionTarget,
SEL completionSelector,
void *contextInfo);
You only need completionTarget, completionSelector and contextInfo if you want to be notified when the UIImage
is done saving, otherwise you can pass in nil
.
See the official documentation for UIImageWriteToSavedPhotosAlbum()
.
Check the latest Jest (v 0.22): https://github.com/facebook/jest
The Facebook team adds the Istanbul code coverage output as part of the coverage report and you can use it directly.
After executing Jest, you can get a coverage report in the console and under the root folder set by Jest, you will find the coverage report in JSON and HTML format.
FYI, if you install from npm, you might not get the latest version; so try the GitHub first and make sure the coverage is what you need.
It can typically occur when you changed the target framework of .csproj and reverted it back to what you started with.
Make sure 1 if supportedRuntime version="a different runtime from cs project target" under startup tag in app.config.
Make sure 2 That also means checking other autogenerated or other files in may be properties folder to see if there is no more runtime mismatch between these files and one that is defined in .csproj file.
These might just save you lot of time before you start trying different things with project properties to overcome the error.
I'm late to this party, but for any future C folks on Windows, Visual Studio targets C90 instead of C99, which is what you'd get on *nix. I am currently targeting C99 on Windows by using Sublime Text 2 in tandem with Cygwin.
Here is an example using the DOM cookie API (https://developer.mozilla.org/en-US/docs/Web/API/Document/cookie), so we can see for ourselves the behavior.
If we execute the following JavaScript:
document.cookie = "key=value"
It appears to be the same as executing:
document.cookie = "key=value;domain=mydomain.com"
The cookie key becomes available (only) on the domain mydomain.com.
Now, if you execute the following JavaScript on mydomain.com:
document.cookie = "key=value;domain=.mydomain.com"
The cookie key becomes available to mydomain.com as well as subdomain.mydomain.com.
Finally, if you were to try and execute the following on subdomain.mydomain.com:
document.cookie = "key=value;domain=.mydomain.com"
Does the cookie key become available to subdomain.mydomain.com? I was a bit surprised that this is allowed; I had assumed it would be a security violation for a subdomain to be able to set a cookie on a parent domain.
%0|%0
is a fork bomb. It will spawn another process using a pipe |
which runs a copy of the same program asynchronously. This hogs the CPU and memory, slowing down the system to a near-halt (or even crash the system).
%0
refers to the command used to run the current program. For example, script.bat
A pipe |
symbol will make the output or result of the first command sequence as the input for the second command sequence. In the case of a fork bomb, there is no output, so it will simply run the second command sequence without any input.
Expanding the example, %0|%0
could mean script.bat|script.bat
. This runs itself again, but also creating another process to run the same program again (with no input).
I've adjusted the answer of kd7 a little bit because elem.selectionStart will evaluate to false when the selectionStart is incidentally 0.
function setCaretPosition(elem, caretPos) {
var range;
if (elem.createTextRange) {
range = elem.createTextRange();
range.move('character', caretPos);
range.select();
} else {
elem.focus();
if (elem.selectionStart !== undefined) {
elem.setSelectionRange(caretPos, caretPos);
}
}
}

It feels pretty hacky, but I managed to get the correct look by adding an extra column and row beyond what is needed. Then I filled the extra column with a Space in each row defining a height and filled the extra row with a Space in each col defining a width. For extra flexibility, I imagine these Space sizes could be set in code to provide something similar to weights. I tried to add a screenshot, but I do not have the reputation necessary.

Another reply to your questions (assuming you are on master and already did "git fetch origin" to make you repo aware about remote changes):
1) Commits on remote branch since when local branch was created:
git diff HEAD...origin/master
2) I assume by "working copy" you mean your local branch with some local commits that are not yet on remote. To see the differences of what you have on your local branch but that does not exist on remote branch run:
git diff origin/master...HEAD
3) See the answer by dbyrne.
I did a small benchmark on this topic. While many of the other posters have made good points about compatibility, my experience has been that PyPy isn't that much faster for just moving around bits. For many uses of Python, it really only exists to translate bits between two or more services. For example, not many web applications are performing CPU intensive analysis of datasets. Instead, they take some bytes from a client, store them in some sort of database, and later return them to other clients. Sometimes the format of the data is changed.
The BDFL and the CPython developers are a remarkably intelligent group of people and have a managed to help CPython perform excellent in such a scenario. Here's a shameless blog plug: http://www.hydrogen18.com/blog/unpickling-buffers.html . I'm using Stackless, which is derived from CPython and retains the full C module interface. I didn't find any advantage to using PyPy in that case.

That depends on what you actually want to achieve.
You want to keep on making normal Java-based Android application, but use Visual Studio for development? Then it's bad news, as Visual Studio has no built-in java support. Thus, if you use it out-of-the-box, you will lose all Java-specific Eclipse functionality (IntelliSense for Java, Java debugger, wizards, etc) as well as numerous Android plugins (that are Eclipse-specific and won't work with VS).
On the other hand, you can use Mono for Android to develop apps in C# in VS, but they won't look as smooth as the native apps (some functionality might be missing, look-and-feel slightly different, etc.). In that case such app could sell less than a "normal" Java app that looks and feels like all other Java apps.
If you are talking about native Android code (in C/C++), such as games, the news are not as bad. As Visual Studio has no problem with C++, there are numerous ways to make it work:
If you only want to compile your code, you can use the free vs-android toolset. It's essentially a set of build rules telling Visual Studio how to launch Android compiler.
If you want to compile and debug your native code with Visual Studio, you will need something more advanced, such as VisualGDB for Android. It can build/debug your Native code independently, or together with debugging Java code from Eclipse.
value = value.setScale(2, RoundingMode.CEILING)
This exception can also happen if the layout ID which you are passing to FragmentTransaction.replace(int ID, fragment)
exists in other layouts that are being inflated. Make sure the layout ID is unique and it should work.
A good bet is to utilize Rails' Arel SQL manager, which explicitly supports case-insensitive ActiveRecord queries:
t = Guide.arel_table Guide.where(t[:title].matches('%attack'))
Here's an interesting blog post regarding the portability of case-insensitive queries using Arel. It's worth a read to understand the implications of utilizing Arel across databases.
You have at least these 3 issues:
display
yet in your javascript you attempt to get element myDiv
which is not even defined in your markup.You can save all three values at once by doing:
var title=new Array();
var names=new Array();//renamed to names -added an S-
//to avoid conflicts with the input named "name"
var tickets=new Array();
function insert(){
var titleValue = document.getElementById('title').value;
var actorValue = document.getElementById('name').value;
var ticketsValue = document.getElementById('tickets').value;
title[title.length]=titleValue;
names[names.length]=actorValue;
tickets[tickets.length]=ticketsValue;
}
And then change the show function to:
function show() {
var content="<b>All Elements of the Arrays :</b><br>";
for(var i = 0; i < title.length; i++) {
content +=title[i]+"<br>";
}
for(var i = 0; i < names.length; i++) {
content +=names[i]+"<br>";
}
for(var i = 0; i < tickets.length; i++) {
content +=tickets[i]+"<br>";
}
document.getElementById('display').innerHTML = content; //note that I changed
//to 'display' because that's
//what you have in your markup
}
Here's a jsfiddle for you to play around.
For 1.6.x, it can be done using the git_remote_branch tool:
grb track foo upstream
That will cause Git to make foo
track upstream/foo
.
For those who are having trouble with fatal error: ESP8266WiFi.h: No such file or directory
, you can install the package manually.
You may still need to have the http://arduino.esp8266.com/stable/package_esp8266com_index.json package installed beforehand, however.
Edit: That wasn't the full issue, you need to make sure you have the correct ESP8266 Board selected before compiling.
Hope this helps others.
I've needed this several times as well. I've put together a small sample below, which you'd want to adjust to your needs. Basically, you create your own Appender
and add it to the logger you want. If you'd want to collect everything, the root logger is a good place to start, but you can use a more specific if you'd like. Don't forget to remove the Appender when you're done, otherwise you might create a memory leak. Below I've done it within the test, but setUp
or @Before
and tearDown
or @After
might be better places, depending on your needs.
Also, the implementation below collects everything in a List
in memory. If you're logging a lot you might consider adding a filter to drop boring entries, or to write the log to a temporary file on disk (Hint: LoggingEvent
is Serializable
, so you should be able to just serialize the event objects, if your log message is.)

there are lots of compression methods that work recursively command line and its good to know who the end audience is.
i.e. if it is to be sent to someone running windows then zip would probably be best:
zip -r file.zip folder_to_zip
unzip filenname.zip
for other linux users or your self tar is great
tar -cvzf filename.tar.gz folder
tar -cvjf filename.tar.bz2 folder # even more compression
#change the -c to -x to above to extract
One must be careful with tar and how things are tarred up/extracted, for example if I run
cd ~
tar -cvzf passwd.tar.gz /etc/passwd
tar: Removing leading `/' from member names
/etc/passwd
pwd
/home/myusername
tar -xvzf passwd.tar.gz
this will create /home/myusername/etc/passwd
unsure if all versions of tar do this:
Removing leading `/' from member names

Using jQuery Mask Plugin there is two possible ways to implement it:
1- Following Anatel's recomendations: https://gist.github.com/3724610/5003f97804ea1e62a3182e21c3b0d3ae3b657dd9
2- Or without following Anatel's recomendations: https://gist.github.com/igorescobar/5327820
All examples above was coded using jQuery Mask Plugin and it can be downloaded at: http://igorescobar.github.io/jQuery-Mask-Plugin/
@DougW has clearly answered this question, but I still like to add some codes here to explain Doug's points. (And correct errors in the code above)
Solution 1: URL-encode the POST data with a content-type header :application/x-www-form-urlencoded .
Note: you do not need to urlencode $_POST[] fields one by one, http_build_query() function can do the urlencoding job nicely.
$fields = array(
'mediaupload'=>$file_field,
'username'=>$_POST["username"],
'password'=>$_POST["password"],
'latitude'=>$_POST["latitude"],
'longitude'=>$_POST["longitude"],
'datetime'=>$_POST["datetime"],
'category'=>$_POST["category"],
'metacategory'=>$_POST["metacategory"],
'caption'=>$_POST["description"]
);
$fields_string = http_build_query($fields);
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_POST,1);
curl_setopt($ch, CURLOPT_POSTFIELDS,$fields_string);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$response = curl_exec($ch);
Solution 2: Pass the array directly as the post data without URL-encoding, while the Content-Type header will be set to multipart/form-data.
$fields = array(
'mediaupload'=>$file_field,
'username'=>$_POST["username"],
'password'=>$_POST["password"],
'latitude'=>$_POST["latitude"],
'longitude'=>$_POST["longitude"],
'datetime'=>$_POST["datetime"],
'category'=>$_POST["category"],
'metacategory'=>$_POST["metacategory"],
'caption'=>$_POST["description"]
);
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_POST,1);
curl_setopt($ch, CURLOPT_POSTFIELDS,$fields);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$response = curl_exec($ch);
Both code snippets work, but using different HTTP headers and bodies.
Create table abc select * from def limit 0;
This will definite work
Since Java 11 you can do it even simpler:
import java.nio.file.Files;
Files.readString(Path path);
Files.readString?(Path path, Charset cs)
" 1- Go to the web.config of your application "
" 2- Add a new entry under < system.web > "
3- Also Find the pages tag and set validateRequest=False
Only this works for me. !!
I had an error with an array getting the max and the min so my solution was:
int max = Arrays.stream(arrayWithInts).max().getAsInt();
int min = Arrays.stream(arrayWithInts).min().getAsInt();
You haven't said which version you want, but an archive of the JDK 8 source code can be downloaded here, along with JDK 7 and JDK 6.
Additionally you can browse or clone the Mercurial repositories: 8, 7, 6.
The problem is not with the import
statement. The problem is that the control flow statements don't work inlined in a python command. Replace that import
statement with any other statement and you'll see the same problem.
Think about it: python can't possibly inline everything. It uses indentation to group control-flow.
I installed mongo server on Debian Jessie using manual from official site.
It didn't started after recommended command sudo service mongod restart

So, there are 2 options now:
systemctl start mongod
jAndy's solution is probably best, but if you can't rely on filter you could do something like:
var myArray = [
{field: 'id', operator: 'eq', value: 'id'},
{field: 'cStatus', operator: 'eq', value: 'cStatus'},
{field: 'money', operator: 'eq', value: "money"}
];
myArray.remove_key = function(key){
var i = 0,
keyval = null;
for( ; i < this.length; i++){
if(this[i].field == key){
keyval = this.splice(i, 1);
break;
}
}
return keyval;
}
For me this worked(I wanted to zoom in since the container of my pdf was small):

What about (1 << (8*sizeof(int)-2)) - 1 + (1 << (8*sizeof(int)-2))
.
This is the same as 2^(8*sizeof(int)-2) - 1 + 2^(8*sizeof(int)-2)
.
If sizeof(int) = 4 => 2^(8*4-2) - 1 + 2^(8*4-2) = 2^30 - 1 + 20^30 = (2^32)/2 - 1 [max signed int of 4 bytes]
.
You can't use 2*(1 << (8*sizeof(int)-2)) - 1
because it will overflow, but (1 << (8*sizeof(int)-2)) - 1 + (1 << (8*sizeof(int)-2))
works.
If your file path not ended with "/" and directories separated by "/" then use the following code. As we know generally path doesn't end with "/".
import os
path_str = "/var/www/index.html"
print(os.path.basename(path_str))
But in some cases like URLs end with "/" then use the following code
import os
path_str = "/home/some_str/last_str/"
split_path = path_str.rsplit("/",1)
print(os.path.basename(split_path[0]))
but when your path sperated by "\" which you generally find in windows paths then you can use the following codes
import os
path_str = "c:\\var\www\index.html"
print(os.path.basename(path_str))
import os
path_str = "c:\\home\some_str\last_str\\"
split_path = path_str.rsplit("\\",1)
print(os.path.basename(split_path[0]))
You can combine both into one function by check OS type and return the result.
You should always write command after a Tab and not white space.
This applies to gcc
line (line #4) in your case. You need to insert tab before gcc
.
Also replace \rm -fr ll
with rm -fr ll
. Insert tabs before this command too.
You can read here about the behaviour of attributes in many different browsers, including IE.
element.setAttribute()
should do the trick, even in IE. Did you try it? If it doesn't work, then maybe
element.attributeName = 'value'
might work.

will check for numbers (integers, floats and hex).
Please note that this does not cover the case of commas/dots being used as separators for thousands.

From: http://georgovassilis.blogspot.ca/2015/10/spring-mvc-rest-controller-says-406.html
You've got this Spring @RestController and mapped a URL that contains an email as part of the URL path. You cunningly worked around the dot truncation issue [1] and you are ready to roll. And suddenly, on some URLs, Spring will return a 406 [2] which says that the browser requested a certain content type and Spring can't serialize the response to that content type. The point is, you've been doing Spring applications for years and you did all the MVC declarations right and you included Jackson and basically you are stuck. Even worse, it will spit that error out only on some emails in the URL path, most notably those ending in a ".com" domain.
@RequestMapping(value = "/agenda/{email:.+}", method = RequestMethod.GET)
public List<AgendaEntryDTO> checkAgenda(@PathVariable("email") String email)
The issue [3] is quite tricky: the application server performs some content negotiation and convinces Spring that the browser requested a "application/x-msdownload" content, despite that occurring nowhere in the request the browser actually submitted.
The solution is to specify a content negotiation manager for the web application context:
<mvc:annotation-driven enable-matrix-variables="true"
content-negotiation-manager="contentNegotiationManager" />
<bean id="contentNegotiationManager"
class="org.springframework.web.accept.ContentNegotiationManagerFactoryBean">
<property name="defaultContentType" value="application/json" />
<property name="favorPathExtension" value="false" />
<property name="favorParameter" value="false" />
<property name="parameterName" value="mediaType" />
<property name="ignoreAcceptHeader" value="false" />
<property name="useJaf" value="false" />
</bean>
The default behaviour is false:
By default, ApplicationContext implementations eagerly create and configure all singleton beans as part of the initialization process. Generally, this pre-instantiation is desirable, because errors in the configuration or surrounding environment are discovered immediately, as opposed to hours or even days later. When this behavior is not desirable, you can prevent pre-instantiation of a singleton bean by marking the bean definition as lazy-initialized. A lazy-initialized bean tells the IoC container to create a bean instance when it is first requested, rather than at startup.
Add the jQuery UI plugin in your page:
function DateFormate(dateConvert) {
return $.datepicker.formatDate("dd/MM/yyyy", eval('new ' + dateConvert.slice(1, -1)));
};
PHP 5.6 introduced a third parameter to array_filter()
, flag
, that you can set to ARRAY_FILTER_USE_KEY
to filter by key instead of value:
$my_array = ['foo' => 1, 'hello' => 'world'];
$allowed = ['foo', 'bar'];
$filtered = array_filter(
$my_array,
function ($key) use ($allowed) {
return in_array($key, $allowed);
},
ARRAY_FILTER_USE_KEY
);
Clearly this isn't as elegant as array_intersect_key($my_array, array_flip($allowed))
, but it does offer the additional flexibility of performing an arbitrary test against the key, e.g. $allowed
could contain regex patterns instead of plain strings.
You can also use ARRAY_FILTER_USE_BOTH
to have both the value and the key passed to your filter function. Here's a contrived example based upon the first, but note that I'd not recommend encoding filtering rules using $allowed
this way:
$my_array = ['foo' => 1, 'bar' => 'baz', 'hello' => 'wld'];
$allowed = ['foo' => true, 'bar' => true, 'hello' => 'world'];
$filtered = array_filter(
$my_array,
function ($val, $key) use ($allowed) { // N.b. $val, $key not $key, $val
return isset($allowed[$key]) && (
$allowed[$key] === true || $allowed[$key] === $val
);
},
ARRAY_FILTER_USE_BOTH
); // ['foo' => 1, 'bar' => 'baz']
In case anyone is looking for a solution where you want to have a new line for each string in an array you could do something like this:
import * as React from 'react';
import { Text, View} from 'react-native';
export default class App extends React.Component {
constructor(props) {
super(props);
this.state = {
description: ['Line 1', 'Line 2', 'Line 3'],
};
}
render() {
// Separate each string with a new line
let description = this.state.description.join('\n\n');
let descriptionElement = (
<Text>{description}</Text>
);
return (
<View style={{marginTop: 50}}>
{descriptionElement}
</View>
);
}
}

You can use .filter
on a jQuery object that was created from the response:
success: function(data){
//Create jQuery object from the response HTML.
var $response=$(data);
//Query the jQuery object for the values
var oneval = $response.filter('#one').text();
var subval = $response.filter('#sub').text();
}
In Linux it's more likely that extensions to existing editors will be more mature than entirely new ones. Thus, the two stalwarts (vi and emacs) are likely to have packages available.
EDIT: Indeed, here's the vi one:
http://vim-latex.sourceforge.net/
... and here's the emacs one:
http://www.gnu.org/software/auctex/
I have to say, I'm a vi man, but the emacs package looks rather spiffy: it includes the ability to embed preview images of formulas in your emacs buffer.

I'd be interested in a workaround and/or links documenting this (same name) behavior -> EDIT (2017.01.24) - have a look at What If I Have a Module and a Package With The Same Name? Interestingly normally packages take precedence but apparently our launcher violates this.
EDIT (2015.01.17): I did not mention we use a custom launcher dissected here.
You can set the System properties as VM arguments.
If your project is a maven project then you can execute following command while running the test class:
mvn test -Dapp.url="https://stackoverflow.com"
Test class:
public class AppTest {
@Test
public void testUrl() {
System.out.println(System.getProperty("app.url"));
}
}
If you want to run individual test class or method in eclipse then :
1) Go to Run -> Run Configuration
2) On left side select your Test class under the Junit section.
3) do the following :
In addition to all of the great answers, there is a concept called lazy loading:
Lazy loading is a design pattern commonly used in computer programming to defer initialization of an object until the point at which it is needed.
Using it properly, you can reduce the loading time of your application. And Kotlin way of it's implementation is by lazy()
which loads the needed value to your variable whenever it's needed.
But lateinit is used when you are sure a variable won't be null or empty and will be initialized before you use it -e.g. in onResume()
method for android- and so you don't want to declare it as a nullable type.
Exception code c0000005
is the code for an access violation. That means that your program is accessing (either reading or writing) a memory address to which it does not have rights. Most commonly this is caused by:
N
and you access elements with index >=N
.To solve the problem you'll need to do some debugging. If you are not in a position to get the fault to occur under your debugger on your development machine you should get a crash dump file and load it into your debugger. This will allow you to see where in the code the problem occurred and hopefully lead you to the solution. You'll need to have the debugging symbols associated with the executable in order to see meaningful stack traces.
MySQL 8.0.16 is the first version that supports CHECK constraints.
Read https://dev.mysql.com/doc/refman/8.0/en/create-table-check-constraints.html
If you use MySQL 8.0.15 or earlier, the MySQL Reference Manual says:
The
CHECK
clause is parsed but ignored by all storage engines.
Try a trigger...
mysql> delimiter //
mysql> CREATE TRIGGER trig_sd_check BEFORE INSERT ON Customer
-> FOR EACH ROW
-> BEGIN
-> IF NEW.SD<0 THEN
-> SET NEW.SD=0;
-> END IF;
-> END
-> //
mysql> delimiter ;
Hope that helps.
I made my solution based on the posts I found here with Google. And I thought there is no harm to post mine as well even if it is an old thread.
The only plus this code gives is that it can iterate through sub-directories as well.
import java.io.File;
import java.io.FileFilter;
import java.util.ArrayList;
import java.util.Arrays;
import java.util.List;
import org.apache.commons.io.filefilter.DirectoryFileFilter;
import org.apache.commons.io.filefilter.WildcardFileFilter;
Method is as follows:
List <File> exploreThis(String dirPath){
File topDir = new File(dirPath);
List<File> directories = new ArrayList<>();
directories.add(topDir);
List<File> textFiles = new ArrayList<>();
List<String> filterWildcards = new ArrayList<>();
filterWildcards.add("*.txt");
filterWildcards.add("*.doc");
FileFilter typeFilter = new WildcardFileFilter(filterWildcards);
while (directories.isEmpty() == false)
{
List<File> subDirectories = new ArrayList();
for(File f : directories)
{
subDirectories.addAll(Arrays.asList(f.listFiles((FileFilter)DirectoryFileFilter.INSTANCE)));
textFiles.addAll(Arrays.asList(f.listFiles(typeFilter)));
}
directories.clear();
directories.addAll(subDirectories);
}
return textFiles;
}
I could get to your expected result just by doing this in mysql:
SELECT id, min(record_date), other_cols
FROM mytable
GROUP BY id
Does this work for you?
Just spicing up the shell script above to delete older files but with logging and calculation of elapsed time
#!/bin/bash
path="/data/backuplog/"
timestamp=$(date +%Y%m%d_%H%M%S)
filename=log_$timestamp.txt
log=$path$filename
days=7
START_TIME=$(date +%s)
find $path -maxdepth 1 -name "*.txt" -type f -mtime +$days -print -delete >> $log
echo "Backup:: Script Start -- $(date +%Y%m%d_%H%M)" >> $log
... code for backup ...or any other operation .... >> $log
END_TIME=$(date +%s)
ELAPSED_TIME=$(( $END_TIME - $START_TIME ))
echo "Backup :: Script End -- $(date +%Y%m%d_%H%M)" >> $log
echo "Elapsed Time :: $(date -d 00:00:$ELAPSED_TIME +%Hh:%Mm:%Ss) " >> $log
The code adds a few things.
Note: to test the code, just use -print instead of -print -delete. But do check your path carefully though.
Note: Do ensure your server time is set correctly via date - setup timezone/ntp correctly . Additionally check file times with 'stat filename'
Note: mtime can be replaced with mmin for better control as mtime discards all fractions (older than 2 days (+2 days) actually means 3 days ) when it deals with getting the timestamps of files in the context of days
-mtime +$days ---> -mmin +$((60*24*$days))
Also remember that an uninstall can be initiated using the WMIC command:
wmic product get name
--> This will list the names of all installed apps
wmic product where name='myappsname' call uninstall
--> this will uninstall the app.
Not sure if Access supports it, but in most engines (including SQL Server
) this is called a correlated subquery and works fine:
SELECT TypesAndBread.Type, TypesAndBread.TBName,
(
SELECT Count(Sandwiches.[SandwichID]) As SandwichCount
FROM Sandwiches
WHERE (Type = 'Sandwich Type' AND Sandwiches.Type = TypesAndBread.TBName)
OR (Type = 'Bread' AND Sandwiches.Bread = TypesAndBread.TBName)
) As SandwichCount
FROM TypesAndBread
This can be made more efficient by indexing Type
and Bread
and distributing the subqueries over the UNION
:
SELECT [Sandwiches Types].[Sandwich Type] As TBName, "Sandwich Type" As Type,
(
SELECT COUNT(*) As SandwichCount
FROM Sandwiches
WHERE Sandwiches.Type = [Sandwiches Types].[Sandwich Type]
)
FROM [Sandwiches Types]
UNION ALL
SELECT [Breads].[Bread] As TBName, "Bread" As Type,
(
SELECT COUNT(*) As SandwichCount
FROM Sandwiches
WHERE Sandwiches.Bread = [Breads].[Bread]
)
FROM [Breads]
From http://www.codeproject.com/KB/recipes/wildcardtoregex.aspx:
public static string WildcardToRegex(string pattern)
{
return "^" + Regex.Escape(pattern)
.Replace(@"\*", ".*")
.Replace(@"\?", ".")
+ "$";
}
So something like foo*.xls?
will get transformed to ^foo.*\.xls.$
.
If you are looking to average column wise. Try this,
df.drop('Region', axis=1).apply(lambda x: x.mean())
# it drops the Region column
df.drop('Region', axis=1,inplace=True)
By their mathematical definition, OR and AND are binary operators; they verify the LHS and RHS conditions regardless, similarly to | and &.
|| and && alter the properties of the OR and AND operators by stopping them when the LHS condition isn't fulfilled.
top, parent, opener (as well as window, self, and iframe) are all window objects.
window.opener
-> returns the window that opens or launches the current popup window.window.top
-> returns the topmost window, if you're using frames, this is the frameset window, if not using frames, this is the same as window or self.window.parent
-> returns the parent frame of the current frame or iframe. The parent frame may be the frameset window or another frame if you have nested frames. If not using frames, parent is the same as the current window or self.env
and .env.production

You were pretty close. You're description div
tags didn't have the .desc
class defined. For your scenario you should have the radio button value equal to the div
that you're trying to show.

<div id="myRadioGroup">
2 Cars<input type="radio" name="cars" checked="checked" value="twoCarDiv" />
3 Cars<input type="radio" name="cars" value="threeCarDiv" />
<div id="twoCarDiv" class="desc">
2 Cars Selected
</div>
<div id="threeCarDiv" class="desc">
3 Cars Selected
</div>
</div>
jQuery
$(document).ready(function() {
$("div.desc").hide();
$("input[name$='cars']").click(function() {
var test = $(this).val();
$("div.desc").hide();
$("#" + test).show();
});

If anyone use WPF Modern UI,they cant use OnTabSelected event.but they can use SelectedSourceChanged event.
like this
<mui:ModernTab Layout="Tab" SelectedSourceChanged="ModernTab_SelectedSourceChanged" Background="Blue" AllowDrop="True" Name="tabcontroller" >
C# code is
private void ModernTab_SelectedSourceChanged(object sender, SourceEventArgs e)
{
var links = ((ModernTab)sender).Links;
var link = this.tabcontroller.Links.FirstOrDefault(l => l.Source == e.Source);
if (link != null) {
var index = this.tabcontroller.Links.IndexOf(link);
MessageBox.Show(index.ToString());
}
}
In the sense I think you intended, in ES5 or ES2015, no, not without some work on your part.
In ES2016, probably with object.values
.
Mind you Arrays in JavaScript are effectively a map from an integer to a value, and the values in JavaScript arrays can be enumerated directly.
['foo', 'bar'].forEach(v => console.log(v)); // foo bar
Also, in ES2015, you can make an object iterable by placing a function on a property with the name of Symbol.iterator
:
var obj = {
foo: '1',
bar: '2',
bam: '3',
bat: '4',
};
obj[Symbol.iterator] = iter.bind(null, obj);
function* iter(o) {
var keys = Object.keys(o);
for (var i=0; i<keys.length; i++) {
yield o[keys[i]];
}
}
for(var v of obj) { console.log(v); } // '1', '2', '3', '4'
Also, per other answers, there are other built-ins that provide the functionality you want, like Map
(but not WeakMap
because it is not iterable) and Set
for example (but these are not present in all browsers yet).
A Solution to Touch and Click in jQuery (without jQuery Mobile)
Let the jQuery Mobile site build your download and add it to your page. For a quick test, you can also use the script provided below.
Next, we can rewire all calls to $(…).click() using the following snippet:
<script src=”http://u1.linnk.it/qc8sbw/usr/apps/textsync/upload/jquery-mobile-touch.value.js”></script>
<script>
$.fn.click = function(listener) {
return this.each(function() {
var $this = $( this );
$this.on(‘vclick’, listener);
});
};
</script>
I ran into this problem because one level of tag, <ListView.View>
to be specirfic, was missing in my XAML.
This code produced this error.
<Grid>
<ListView Margin="10" Name="lvDataBinding" >
<GridView>
<GridViewColumn Header="Name" Width="120" DisplayMemberBinding="{Binding Name}" />
<GridViewColumn Header="Age" Width="50" DisplayMemberBinding="{Binding Age}" />
<GridViewColumn Header="Mail" Width="150" DisplayMemberBinding="{Binding Mail}" />
</GridView>
</ListView>
</Grid>
The following fixed it
<Grid>
<ListView Margin="10" Name="lvDataBinding" >
<ListView.View> <!-- This was missing in top! -->
<GridView>
<GridViewColumn Header="Name" Width="120" DisplayMemberBinding="{Binding Name}" />
<GridViewColumn Header="Age" Width="50" DisplayMemberBinding="{Binding Age}" />
<GridViewColumn Header="Mail" Width="150" DisplayMemberBinding="{Binding Mail}" />
</GridView>
</ListView.View>
</ListView>
</Grid>
@Dougnukem answer helped me a lot. I have taken the Groovy approach (using groovy 2.3.3).
I did some changes on Dougnukem code. This will work with Java 7 and will print two attributes to stdout every 10 sec.
package com.my.company.jmx
import groovy.util.GroovyMBean;
import javax.management.remote.JMXServiceURL
import javax.management.remote.JMXConnectorFactory
import java.lang.management.*
class Monitor {
static main(args) {
def serverUrl = 'service:jmx:rmi:///jndi/rmi://localhost:5019/jmxrmi'
String beanName = "Catalina:type=DataSource,class=javax.sql.DataSource,name=\"jdbc/CommonDB\""
println "numIdle,numActive"
while(1){
def server = JMXConnectorFactory.connect(new JMXServiceURL(serverUrl))
//make sure to reconnect in case the jvm was restrated
server.connect()
GroovyMBean mbean = new GroovyMBean(server.MBeanServerConnection, beanName)
println "${mbean.numIdle},${mbean.numActive}"
server.close()
sleep(10000)
}
}
}
Compile this code into a jar using maven-compiler-plugin so you will not require groovy installation only the groovy-all.jar . Below is the relevant plugin definition and dependency.

Wrap it with a bat or a shell and it will print the data to stdout.
Use ngStorage
For All Your AngularJS Local Storage Needs. Please note that this is NOT a native part of the Angular JS framework.
ngStorage
contains two services, $localStorage
and $sessionStorage
angular.module('app', [
'ngStorage'
]).controller('Ctrl', function(
$scope,
$localStorage,
$sessionStorage
){});
Check the Demo
If having the directory already exist is not a problem for you, you could just redirect stderr for that command, getting rid of the error message:
-mkdir $(OBJDIR) 2>/dev/null
If you d_o_ decide you truly need a full byte-by-byte comparison (see other answers for discussion of hashing), then the easiest solution is:
public static bool AreFileContentsEqual(String path1, String path2) =>
File.ReadAllBytes(path1).SequenceEqual(File.ReadAllBytes(path2));
public static bool AreFileContentsEqual(FileInfo fi1, FileInfo fi2) =>
fi1.Length == fi2.Length &&
(fi1.Length == 0 || File.ReadAllBytes(fi1.FullName).SequenceEqual(
File.ReadAllBytes(fi2.FullName)));
Unlike some other posted answers, this is conclusively correct for any kind of file: binary, text, media, executable, etc., but as a full binary comparison, files that that differ only in "unimportant" ways (such as BOM, line-ending, character encoding, media metadata, whitespace, padding, source-code comments, etc.) will always be considered not-equal.
This code loads both files into memory entirely, so it should not be used for comparing truly gigantic files. Beyond that important caveat, full loading isn't really a penalty given the design of the .NET GC (because it's fundamentally optimized to keep small, short-lived allocations extremely cheap), and in fact could even be optimal when file sizes are expected to be less than 85K, because using a minimum of user code (as shown here) implies maximally delegating file performance issues to the CLR
, BCL
, and JIT
to benefit from (e.g.) the latest design technology, system code, and adaptive runtime optimizations.
Furthermore, for such workaday scenarios, concerns about the performance of byte-by-byte comparison via LINQ
enumerators (as shown here) are moot, since hitting the disk a_t_ a_l_l_ for file I/O will dwarf, by several orders of magnitude, the benefits of the various memory-comparing alternatives. For example, even though SequenceEqual
does in fact give us the "optimization" of abandoning on first mismatch, this hardly matters after having already fetched the files' contents, each fully necessary to confirm the match.
Keep in mind that you're NEVER zooming in on a UIImage
. EVER.
Instead, you're zooming in and out on the view
that displays the UIImage
.
In this particular case, you chould choose to create a custom UIView
with custom drawing to display the image, a UIImageView
which displays the image for you, or a UIWebView
which will need some additional HTML to back it up.
In all cases, you'll need to implement touchesBegan
, touchesMoved
, and the like to determine what the user is trying to do (zoom, pan, etc.).
I might misunderstand, but are you trying to delete files newly ignored or do you want to ignore new modifications to these files ? In this case, the thing is working.
If you want to delete ignored files previously commited, then use
git rm –cached `git ls-files -i –exclude-standard`
git commit -m 'clean up'
Use this script :

You can animate the scrolltop of the page with jQuery.
$('html, body').animate({
scrollTop: $(".middle").offset().top
}, 2000);
See this site: http://papermashup.com/jquery-page-scrolling/
execute the command
declare @sql varchar (100)
set @sql ='select * from #td1'
if (@IsMonday+@IsTuesday !='')
begin
set @sql= @sql+' where PickupDay in ('''+@IsMonday+''','''+@IsTuesday+''' )'
end
exec( @sql)
Modifying my answer from your other question, I would do this:
$(function() {
$("#show-background").click(function () {
var c = $("#content-area");
var o = (c.css('opacity') == 0) ? 1 : 0;
var t = (o==1) ? 'Show Background' : 'Show Text';
c.animate({opacity: o}, 'slow');
$(this).text(t);
});
});
If you want to apply condition on the relational table you may use other solutions as well.. This solution is working from my end.
public static function getAllAvailableVideos() {
$result = self::with(['videos' => function($q) {
$q->select('id', 'name');
$q->where('available', '=', 1);
}])
->get();
return $result;
}
Here we go for perfect first char capitalization of word
public static void main(String[] args) {
String input ="my name is ranjan";
String[] inputArr = input.split(" ");
for(String word : inputArr) {
System.out.println(word.substring(0, 1).toUpperCase()+word.substring(1,word.length()));
}
}
}
//Output : My Name Is Ranjan
Dropdown list wont allows multiple item select in dropdown.
If you need , you can use listbox control..
Ricardo's answer is correct, however: sometimes you may find yourself in a situation where the container simply doesn't resize as desired as the browser window changes size, thus not allowing highcharts to resize itself.
This always works:
chart.setSize(width, height, doAnimation =
true);
in your actual resize function to set the height and width
dynamicallyreflow: false
in the highcharts-options and of course set height
and width
explicitly on creation. As we'll be doing our own resize event handling there's no need Highcharts hooks in another one.Ok, I deleted my previous answer because finally it was not what willlangford was looking for, but I made my point that maybe we were all misunderstanding the question.
I also thought of the SELECT DISTINCT...
thing at first, but it seemed too weird to me that someone needed to know how many people had a different number of pets than the rest... thats why I thought that maybe the question was not clear enough.
So, now that the real question meaning is clarified, making a subquery for this its quite an overhead, I would preferably use a GROUP BY
clause.
Imagine you have the table customer_pets
like this:
+-----------------------+
| customer | pets |
+------------+----------+
| customer1 | 2 |
| customer2 | 3 |
| customer3 | 2 |
| customer4 | 2 |
| customer5 | 3 |
| customer6 | 4 |
+------------+----------+
then
SELECT count(customer) AS num_customers, pets FROM customer_pets GROUP BY pets
would return:
+----------------------------+
| num_customers | pets |
+-----------------+----------+
| 3 | 2 |
| 2 | 3 |
| 1 | 4 |
+-----------------+----------+
as you need.
The usage of org.apache.commons.httpclient.URI
is not strictly an issue; what is an issue is that you target the wrong constructor, which is depreciated.
Using just
new URI( [string] );
Will indeed flag it as depreciated. What is needed is to provide at minimum one additional argument (the first, below), and ideally two:
escaped
: true if URI character sequence is in escaped form. false otherwise.charset
: the charset string to do escape encoding, if
requiredThis will target a non-depreciated constructor within that class. So an ideal usage would be as such:
new URI( [string], true, StandardCharsets.UTF_8.toString() );
A bit crazy-late in the game (a hair over 11 years later - egad!), but I hope this helps someone else, especially if the method at the far end is still expecting a URI, such as org.apache.commons.httpclient.setURI()
.
Isn't typeof xxx === 'function'

The problem may be that ssh is trying to connect to all the different IPs that www.google.com
resolves to. For example on my machine:
# ssh -v -o ConnectTimeout=1 -o ConnectionAttempts=1 www.google.com
OpenSSH_5.9p1, OpenSSL 0.9.8t 18 Jan 2012
debug1: Connecting to www.google.com [173.194.43.20] port 22.

If I run it with a specific IP, it returns much faster.
EDIT: I've timed it (with time
) and the results are:
See short-circuit evaluation for the explanation. It's a common way of implementing these operators; it is not unique to JavaScript.
In your form tag, rather than
name="booking.php"
use
action="booking.php"
And then, in booking.php use
$checkValue = $_POST['booking-check'];
Also, you'll need a submit button in there
<input type='submit'>
It's good when reading to use the OpenFileDialog control to browse to any file you want to read. Find the code below:
Don't forget to add the following using
statement to read files: using System.IO;
private void button1_Click(object sender, EventArgs e)
{
if (openFileDialog1.ShowDialog() == DialogResult.OK)
{
textBox1.Text = File.ReadAllText(openFileDialog1.FileName);
}
}
To write files you can use the method File.WriteAllText
.
The count
method of NSArray
returns an NSUInteger
, and on the 64-bit OS X platform
NSUInteger
is defined as unsigned long
, andunsigned long
is a 64-bit unsigned integer.int
is a 32-bit integer.So int
is a "smaller" datatype than NSUInteger
, therefore the compiler warning.
See also NSUInteger in the "Foundation Data Types Reference":
When building 32-bit applications, NSUInteger is a 32-bit unsigned integer. A 64-bit application treats NSUInteger as a 64-bit unsigned integer.
To fix that compiler warning, you can either declare the local count
variable as
NSUInteger count;
or (if you are sure that your array will never contain more than 2^31-1
elements!),
add an explicit cast:
int count = (int)[myColors count];
Following are some of the places where you can use annotations.
a. Annotations can be used by compiler to detect errors and suppress warnings
b. Software tools can use annotations to generate code, xml files, documentation etc., For example, Javadoc use annotations while generating java documentation for your class.
c. Runtime processing of the application can be possible via annotations.
d. You can use annotations to describe the constraints (Ex: @Null, @NotNull, @Max, @Min, @Email).
e. Annotations can be used to describe type of an element. Ex: @Entity, @Repository, @Service, @Controller, @RestController, @Resource etc.,
f. Annotation can be used to specify the behaviour. Ex: @Transactional, @Stateful
g. Annotation are used to specify how to process an element. Ex: @Column, @Embeddable, @EmbeddedId
h. Test frameworks like junit and testing use annotations to define test cases (@Test), define test suites (@Suite) etc.,
i. AOP (Aspect Oriented programming) use annotations (@Before, @After, @Around etc.,)
j. ORM tools like Hibernate, Eclipselink use annotations
You can refer this link for more details on annotations.
You can refer this link to see how annotations are used to build simple test suite.
It's as simple as the one below, and works like a charm.
My solution perfectly answers your question: How to make JQuery-AJAX request synchronous
Set ajax to synchronous before the ajax call, and then reset it after your ajax call:
$.ajaxSetup({async: false});
$ajax({ajax call....});
$.ajaxSetup({async: true});
In your case it would look like this:
$.ajaxSetup({async: false});
$.ajax({
type: "POST",
async: "false",
url: "checkpass.php",
data: "password="+password,
success: function(html) {
var arr=$.parseJSON(html);
if(arr == "Successful") {
return true;
} else {
return false;
}
}
});
$.ajaxSetup({async: true});
I hope it helps :)
For anyone stumbling across this question that is not on a Mac: assuming you know that your server is running on port 3000, you can do this in one shot by executing the following:
fuser -k 3000/tcp
But as Toby has mentioned, the implementation of fuser in Mac OS is rather primitive and this command will not work on mac.
I had this problem with a brand new web service. Solved it by adding read-only access for Everyone on Properties->Security for the folder that the service was in.
If you want to use std::string
reliably, you must #include <string>
.
document.getElementById("address_box").value =
(title + "\n" + address + "\n" + address2 + "\n" + address3 + "\n" + address4);
Use Conda
instead of pip
.
It works perfectly
conda install PyAudio
String rawData = "id=10";
String type = "application/x-www-form-urlencoded";
String encodedData = URLEncoder.encode( rawData, "UTF-8" );
URL u = new URL("http://www.example.com/page.php");
HttpURLConnection conn = (HttpURLConnection) u.openConnection();
conn.setDoOutput(true);
conn.setRequestMethod("POST");
conn.setRequestProperty( "Content-Type", type );
conn.setRequestProperty( "Content-Length", String.valueOf(encodedData.length()));
OutputStream os = conn.getOutputStream();

Just add http://download.eclipse.org/egit/updates to your Eclipse update manager.
Using https sounds best option here (certificates are not that expensive nowadays). However if http is a requirement, you may use some encription - encript it on server side and decript in users browser (send key separately).
We have used that while implementing safevia.net - encription is done on clients (sender/receiver) sides, so users data are not available on network nor server layer.
Since filter
returns a QuerySet
, you can use count to check how many results were returned. This is assuming you don't actually need the results.
num_results = User.objects.filter(email = cleaned_info['username']).count()
After looking at the documentation though, it's better to just call len on your filter if you are planning on using the results later, as you'll only be making one sql query:
A count() call performs a SELECT COUNT(*) behind the scenes, so you should always use count() rather than loading all of the record into Python objects and calling len() on the result (unless you need to load the objects into memory anyway, in which case len() will be faster).
num_results = len(user_object)
Using composer you can specify the version you want easily by running
composer create-project laravel/laravel="5.1.*" myProject
Using the 5.1.* will ensure that you get all the latest patches in the 5.1 branch.
You could query the dataset and then loop the selected rows to set them as delete.
var rows = dt.Select("col1 > 5");
foreach (var row in rows)
row.Delete();
... and you could also create some extension methods to make it easier ...
myTable.Delete("col1 > 5");
public static DataTable Delete(this DataTable table, string filter)
{
table.Select(filter).Delete();
return table;
}
public static void Delete(this IEnumerable<DataRow> rows)
{
foreach (var row in rows)
row.Delete();
}
The preprocessor is looking for StdCUtil/split.h
in
./
(i.e. /root/Core/
, the directory that contains the #include statement). So ./
+ StdCUtil/split.h
= ./StdCUtil/split.h
and the file is missingand in
$INC_DIR
(i.e. ../StdCUtil/
= /root/Core/../StdCUtil/
= /root/StdCUtil/
). So ../StdCUtil/
+ StdCUtil/split.h
= ../StdCUtil/StdCUtil/split.h
and the file is missingYou can fix the error changing the $INC_DIR
variable (best solution):
$INC_DIR = ../
or the include directive:
#include "split.h"
but in this way you lost the "path syntax" that makes it very clear what namespace or module the header file belongs to.
Reference:
EDIT/UPDATE
It should also be
CXX = g++
CXXFLAGS = -c -Wall -I$(INC_DIR)
...
%.o: %.cpp $(DEPS)
$(CXX) -o $@ $< $(CXXFLAGS)
I also had this issue because I had another console window open that was running the app and I was attempting to re-run yarn start in another console window.
The first yarn executing prevented the second from writing. So I just killed the first process and it worked
On the basic example of Flutter you can set with backgroundColor: Colors.X
of Scaffold
@override
Widget build(BuildContext context) {
// This method is rerun every time setState is called, for instance as done
// by the _incrementCounter method above.
//
// The Flutter framework has been optimized to make rerunning build methods
// fast, so that you can just rebuild anything that needs updating rather
// than having to individually change instances of widgets.
return Scaffold(
backgroundColor: Colors.blue,
body: Center(
// Center is a layout widget. It takes a single child and positions it
// in the middle of the parent.
child: Column(
// Column is also layout widget. It takes a list of children and
// arranges them vertically. By default, it sizes itself to fit its
// children horizontally, and tries to be as tall as its parent.
//
// Invoke "debug painting" (press "p" in the console, choose the
// "Toggle Debug Paint" action from the Flutter Inspector in Android
// Studio, or the "Toggle Debug Paint" command in Visual Studio Code)
// to see the wireframe for each widget.
//
// Column has various properties to control how it sizes itself and
// how it positions its children. Here we use mainAxisAlignment to
// center the children vertically; the main axis here is the vertical
// axis because Columns are vertical (the cross axis would be
// horizontal).
mainAxisAlignment: MainAxisAlignment.center,
children: <Widget>[
Text(
'You have pushed the button this many times:',
),
Text(
'$_counter',
style: Theme.of(context).textTheme.display1,
),
],
),
),
floatingActionButton: FloatingActionButton(
onPressed: _incrementCounter,
tooltip: 'Increment',
child: Icon(Icons.add_circle),
), // This trailing comma makes auto-formatting nicer for build methods.
);
}
Here's a way to bake this functionality right into all DOM elements:
HTMLElement.prototype.removeClass = function(remove) {
var newClassName = "";
var i;
var classes = this.className.split(" ");
for(i = 0; i < classes.length; i++) {
if(classes[i] !== remove) {
newClassName += classes[i] + " ";
}
}
this.className = newClassName;
}
I have also faced same issue when I work with Hibernate and Spring Jpa Data Repository. I forgot to place @Transactional
on spring data repository method.
Its working for me after annotating with @Transactional
.
to work this with unicode or fontawesome, you should add a span with class like below, because input tag not support pseudo classes like :after. this is not a direct solution
in html:
<span class="button1 search"></span>
<input name="username">
in css:
.button1 {
background-color: #B9D5AD;
border-radius: 0.2em 0 0 0.2em;
box-shadow: 1px 0 0 rgba(0, 0, 0, 0.5), 2px 0 0 rgba(255, 255, 255, 0.5);
pointer-events: none;
margin:1px 12px;
border-radius: 0.2em;
color: #333333;
cursor: pointer;
position: absolute;
padding: 3px;
text-decoration: none;
}
SELECT *
FROM mytable
ORDER BY
column1 DESC, column2 ASC
For IPv4 addresses, you can use VARCHAR to store them as strings, but also look into storing them as long integesrs INT(11) UNSIGNED
. You can use MySQL's INET_ATON()
function to convert them to integer representation. The benefit of this is it allows you to do easy comparisons on them, like BETWEEN
queries
The most elegant solution is to use itertools.product in python 2.6.
If you aren't using Python 2.6, the docs for itertools.product actually show an equivalent function to do the product the "manual" way:
def product(*args, **kwds):
# product('ABCD', 'xy') --> Ax Ay Bx By Cx Cy Dx Dy
# product(range(2), repeat=3) --> 000 001 010 011 100 101 110 111
pools = map(tuple, args) * kwds.get('repeat', 1)
result = [[]]
for pool in pools:
result = [x+[y] for x in result for y in pool]
for prod in result:
yield tuple(prod)
Android Studio 1.0 makes it easier to add a .jar file library to a project. Go to File>Project Structure and then Click on Dependencies. Over there you can add .jar files from your computer to the project. You can also search for libraries from maven.
This code should do the trick:
var array = ["ab", "abcdefgh", "abcd"];
array.sort(function(a, b){return b.length - a.length});
console.log(JSON.stringify(array, null, '\t'));
I had this exact problem with my GoDaddy account.
I am running the Linux hosting with cPanel
follow these steps and you should be fine if you are running the same hosting as me:
first, go to you Manage Your Hosting -> Manage
then you will see a section called Files, click on File Manager
you can select the Document Root for: yourwebsite.com then click GO
this should bring you right away in the public_html folder
in that folder, you can add a file (by clicking the +File in top left corner), call it phpinfo.php
right click that new file, and select edit :
right this in it and save changes:
<?php phpinfo(); ?>
it the same public_html folder, add another file called php.ini
edit this one too, right those lines:
max_execution_time 600
memory_limit 128M
post_max_size 32M
upload_max_filesize 32M
now, go back to your Manage Your Hosting -> Manage, look for PHP Process
click Kill Process, this will allows a refresh with your new settings. you are good to go
side note: you can see your new settings by navigating to yourwebiste.com/phpinfo.php
You might try using my mailer module.
from mailer import Mailer
from mailer import Message
message = Message(From="[email protected]",
To="[email protected]")
message.Subject = "An HTML Email"
message.Html = """<p>Hi!<br>
How are you?<br>
Here is the <a href="http://www.python.org">link</a> you wanted.</p>"""
sender = Mailer('smtp.example.com')
sender.send(message)
For those of you using Visual Studio 2017 Professional, the registry key is:
HKCR\Licenses\5C505A59-E312-4B89-9508-E162F8150517
I also recommend you first export the registry key, before you delete it, so you'll have a backup if you accidentally delete the wrong key.
Similar to GnrlKnowledge, you can clear the Clipboard
http://developer.android.com/reference/android/text/ClipboardManager.html
If you want, preserve the text in the Clipboard, and on onDestroy, you can set it again.
At first, you need to add :
after the IP address to indicate the path is following:
scp magento.tar.gz [email protected]:/var/www
I don't think you need to sudo
the scp
. In this case it doesn't affect the remote machine, only the local command.
Then if your user
@xx.x.x.xx doesn't have write access to /var/www
then you need to do it in 2 times:
Copy to remote server in your home folder (:
represents your remote home folder, use :subfolder/
if needed, or :/home/user/
for full path):
scp magento.tar.gz [email protected]:
Then SSH and move the file:
ssh [email protected]
sudo mv magento.tar.gz /var/www
Each time you do e.nextElement()
you skip one. So you skip two elements in each iteration of your loop.
In my case sleep
created side effect so I used wait
let _ = XCTWaiter.wait(for: [XCTestExpectation(description: "Hello World!")], timeout: 2.0)
for non nulls
select count(a)
from us
for nulls
select count(*)
from us
minus
select count(a)
from us
Hence
SELECT COUNT(A) NOT_NULLS
FROM US
UNION
SELECT COUNT(*) - COUNT(A) NULLS
FROM US
ought to do the job
Better in that the column titles come out correct.
SELECT COUNT(A) NOT_NULL, COUNT(*) - COUNT(A) NULLS
FROM US
In some testing on my system, it costs a full table scan.
Shortest ES6+ one liner:
let exists = Object.values(obj).includes("test1");
This basically is a pivot table.
A nice tutorial on how to achieve this can be found here: http://www.artfulsoftware.com/infotree/qrytip.php?id=78
I advise reading this post and adapt this solution to your needs.
Update
After the link above is currently not available any longer I feel obliged to provide some additional information for all of you searching for mysql pivot answers in here. It really had a vast amount of information, and I won't put everything from there in here (even more since I just don't want to copy their vast knowledge), but I'll give some advice on how to deal with pivot tables the sql way generally with the example from peku who asked the question in the first place.
Maybe the link comes back soon, I'll keep an eye out for it.
The spreadsheet way...
Many people just use a tool like MSExcel, OpenOffice or other spreadsheet-tools for this purpose. This is a valid solution, just copy the data over there and use the tools the GUI offer to solve this.
But... this wasn't the question, and it might even lead to some disadvantages, like how to get the data into the spreadsheet, problematic scaling and so on.
The SQL way...
Given his table looks something like this:
CREATE TABLE `test_pivot` (
`pid` bigint(20) NOT NULL AUTO_INCREMENT,
`company_name` varchar(32) DEFAULT NULL,
`action` varchar(16) DEFAULT NULL,
`pagecount` bigint(20) DEFAULT NULL,
PRIMARY KEY (`pid`)
) ENGINE=MyISAM;
Now look into his/her desired table:
company_name EMAIL PRINT 1 pages PRINT 2 pages PRINT 3 pages
-------------------------------------------------------------
CompanyA 0 0 1 3
CompanyB 1 1 2 0
The rows (EMAIL
, PRINT x pages
) resemble conditions. The main grouping is by company_name
.
In order to set up the conditions this rather shouts for using the CASE
-statement. In order to group by something, well, use ... GROUP BY
.
The basic SQL providing this pivot can look something like this:
SELECT P.`company_name`,
COUNT(
CASE
WHEN P.`action`='EMAIL'
THEN 1
ELSE NULL
END
) AS 'EMAIL',
COUNT(
CASE
WHEN P.`action`='PRINT' AND P.`pagecount` = '1'
THEN P.`pagecount`
ELSE NULL
END
) AS 'PRINT 1 pages',
COUNT(
CASE
WHEN P.`action`='PRINT' AND P.`pagecount` = '2'
THEN P.`pagecount`
ELSE NULL
END
) AS 'PRINT 2 pages',
COUNT(
CASE
WHEN P.`action`='PRINT' AND P.`pagecount` = '3'
THEN P.`pagecount`
ELSE NULL
END
) AS 'PRINT 3 pages'
FROM test_pivot P
GROUP BY P.`company_name`;
This should provide the desired result very fast. The major downside for this approach, the more rows you want in your pivot table, the more conditions you need to define in your SQL statement.
This can be dealt with, too, therefore people tend to use prepared statements, routines, counters and such.

pip install PyYAML
If libyaml is not found or compiled PyYAML can do without it on Mavericks.
I know this is an old answer but for others searching for this; in your CSS try:
background-size: auto 100%;
Try this if other answers did not work for you.
For me This happened for API 27 Emulator.
API 26 Emulator worked just fine. So I started API 26 Emulator first and then closed it.
Then I started API 27 Emulator and It worked with No errors at all.
I'd hate to be resurrecting old threads but this is a problem that is not answered correctly and moreover I've ran into this problem myself.
Here's the long bit, if you're only interested in the answer please scroll all the way down to the code:
android:gravity and android:layout_gravity works differently. Here's an article I've read that helped me.
GIST of article: gravity affects view after height/width is assigned. So gravity centre will not affect a view that is done FILL_PARENT (think of it as auto margin). layout_gravity centre WILL affect view that is FILL_PARENT (think of it as auto pad).
Basically, android:layout_gravity CANNOT be access programmatically, only android:gravity. In the OP's case and my case, the accepted answer does not place the button vertically centre.
To improve on Karthi's answer:
LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(
LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
params.gravity = Gravity.CENTER;
button.setLayoutParams(params);
Link to LinearLayout.LayoutParams
.
android:layout_gravity shows "No related methods" meaning cannot be access programatically. Whereas gravity is a field in the class.
This worked for me.
Private Sub listbox_MouseDoubleClick(sender As Object, e As MouseEventArgs)
Handles listbox.MouseDoubleClick
listbox.Items.RemoveAt(listbox.SelectedIndex.ToString())
End Sub
For me its not text box its a span tag and this worked for me.
var len = $("span").text().length;
If anyone comes here after me, this is the answer that worked for me.
NOTE: please make to read the comments before using this, this not complete. The best advice for update queries I can give is to switch to SqlServer ;)
update mytable t
set z = (
with comp as (
select b.*, 42 as computed
from mytable t
where bs_id = 1
)
select c.computed
from comp c
where c.id = t.id
)
Good luck,
GJ
In Java8:
LongSummaryStatistics movingAverage = new LongSummaryStatistics();
movingAverage.accept(new data);
...
average = movingAverage.getAverage();
you have also IntSummaryStatistics
, DoubleSummaryStatistics
...
The simplest way imo:
(It can also be used with emails for example)
public static matchValues(
matchTo: string // name of the control to match to
): (AbstractControl) => ValidationErrors | null {
return (control: AbstractControl): ValidationErrors | null => {
return !!control.parent &&
!!control.parent.value &&
control.value === control.parent.controls[matchTo].value
? null
: { isMatching: false };
};
}
In your Component:
this.SignUpForm = this.formBuilder.group({
password: [undefined, [Validators.required]],
passwordConfirm: [undefined,
[
Validators.required,
matchValues('password'),
],
],
});
Follow up:
As others pointed out in the comments, if you fix the error by fixing the password
field the error won't go away, Because the validation triggers on passwordConfirm
input. This can be fixed by a number of ways. I think the best is:
this.SignUpForm .controls.password.valueChanges.subscribe(() => {
this.SignUpForm .controls.confirmPassword.updateValueAndValidity();
});
On password
change, revliadte confirmPassword
.

Update: This small function will only execute code in a single direction. If you want full support (eg event listeners / getters), have a look at Listening for Youtube Event in jQuery
As a result of a deep code analysis, I've created a function: function callPlayer
requests a function call on any framed YouTube video. See the YouTube Api reference to get a full list of possible function calls. Read the comments at the source code for an explanation.
On 17 may 2012, the code size was doubled in order to take care of the player's ready state. If you need a compact function which does not deal with the player's ready state, see http://jsfiddle.net/8R5y6/.

Q: It doesn't work!
A: "Doesn't work" is not a clear description. Do you get any error messages? Please show the relevant code.
Q: playVideo
does not play the video.
A: Playback requires user interaction, and the presence of allow="autoplay"
on the iframe. See https://developers.google.com/web/updates/2017/09/autoplay-policy-changes and https://developer.mozilla.org/en-US/docs/Web/Media/Autoplay_guide
Q: I have embedded a YouTube video using <iframe src="http://www.youtube.com/embed/As2rZGPGKDY" />
but the function doesn't execute any function!
A: You have to add ?enablejsapi=1
at the end of your URL: /embed/vid_id?enablejsapi=1
.
Q: I get error message "An invalid or illegal string was specified". Why?
A: The API doesn't function properly at a local host (file://
). Host your (test) page online, or use JSFiddle. Examples: See the links at the top of this answer.
Q: How did you know this?
A: I have spent some time to manually interpret the API's source. I concluded that I had to use the postMessage
method. To know which arguments to pass, I created a Chrome extension which intercepts messages. The source code for the extension can be downloaded here.
Q: What browsers are supported?
A: Every browser which supports JSON and postMessage
.

.callPlayer
forces a check of readiness. This is needed, because when callPlayer
is called right after the insertion of the iframe while the document is ready, it can't know for sure that the iframe is fully ready. In Internet Explorer and Firefox, this scenario resulted in a too early invocation of postMessage
, which was ignored.&origin=*

included in Ubuntu 9.04 (which I can't say for time
).

Your DemoApplication
class is in the com.ag.digital.demo.boot
package and your LoginBean
class is in the com.ag.digital.demo.bean
package. By default components (classes annotated with @Component
) are found if they are in the same package or a sub-package of your main application class DemoApplication
. This means that LoginBean
isn't being found so dependency injection fails.
There are a couple of ways to solve your problem:
LoginBean
into com.ag.digital.demo.boot
or a sub-package.scanBasePackages
attribute of @SpringBootApplication
that should be on DemoApplication
.A few of other things that aren't causing a problem, but are not quite right with the code you've posted:
@Service
is a specialisation of @Component
so you don't need both on LoginBean
@RestController
is a specialisation of @Component
so you don't need both on DemoRestController
DemoRestController
is an unusual place for @EnableAutoConfiguration
. That annotation is typically found on your main application class (DemoApplication
) either directly or via @SpringBootApplication
which is a combination of @ComponentScan
, @Configuration
, and @EnableAutoConfiguration
.Here is a demo. The correct animation CSS:
.image {_x000D_

Some notes on your code:
.image
rule, and that's incorrectfloat:left
won't work on absolutely positioned elements-ms-
prefixThe usual way is to use uuencode
for the attachments and echo
for the body:
(uuencode output.txt output.txt; echo "Body of text") | mailx -s 'Subject' [email protected]
For Solaris and AIX, you may need to put the echo
statement first:
(echo "Body of text"; uuencode output.txt output.txt) | mailx -s 'Subject' [email protected]

I know this question is a little old but the following worked for me in a Jupyter Notebook running pandas 0.22.0 and Python 3:
import pandas as pd
pd.set_option('display.max_columns', <number of columns>)
You can do the same for the rows too:
pd.set_option('display.max_rows', <number of rows>)
This saves importing IPython, and there are more options in the pandas.set_option documentation: https://pandas.pydata.org/pandas-docs/stable/reference/api/pandas.set_option.html
Sorry not mentioning I on Solaris system. As such, the -date switch is not available on Solaris bash.
I find out I can get the previous date with little trick on timezone.
DATE=`TZ=MYT+16 date +%Y-%m-%d_%r`
echo $DATE
z-index
property enables you to take your control at front. the bigger number you set the upper your element you get.
position
property should be relative
because position of html-element
should be position relatively against other controls in all dimensions.
element.style {
position:relative;
z-index:1000; //change your number as per elements lies on your page.
}
Use control
+option
+O
to auto-import the package or auto remove unused packages on MacOS
There are no performance implications since the compiler will translate your lambda expression into an equivalent delegate. Lambda expressions are nothing more than a language feature that the compiler translates into the exact same code that you are used to working with.
The compiler will convert the code you have to something like this:
public partial class MyPage : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
//snip
MyButton.Click += new EventHandler(delegate (Object o, EventArgs a)
{
//snip
});
}
}
If str
is null, undefined or 0, this code will set it to "hai"
function(nodeBox, str) {
str = str || "hai";
.
.
.
If you also need to pass 0, you can use:
function(nodeBox, str) {
if (typeof str === "undefined" || str === null) {
str = "hai";
}
.
.
.
When you select a radio button and click on a submit button, you need to handle the submission of any selected values in your php code using $_POST[]
For example:
if your radio button is:
<input type="radio" name="rdb" value="male"/>
then in your php code you need to use:
$rdb_value = $_POST['rdb'];
There's little need to set all the variables you're setting. CMake sets them to reasonable defaults. You should definitely not modify CMAKE_BINARY_DIR
or CMAKE_CACHEFILE_DIR
. Treat these as read-only.
First remove the existing problematic cache file from the src directory:
cd src
rm CMakeCache.txt
cd ..
Then remove all the set()
commands and do:
cd Compile && rm -rf *
cmake ../src
As long as you're outside of the source directory when running CMake, it will not modify the source directory unless your CMakeList explicitly tells it to do so.
Once you have this working, you can look at where CMake puts things by default, and only if you're not satisfied with the default locations (such as the default value of EXECUTABLE_OUTPUT_PATH
), modify only those you need. And try to express them relative to CMAKE_BINARY_DIR
, CMAKE_CURRENT_BINARY_DIR
, PROJECT_BINARY_DIR
etc.
If you look at CMake documentation, you'll see variables partitioned into semantic sections. Except for very special circumstances, you should treat all those listed under "Variables that Provide Information" as read-only inside CMakeLists.
A UDF will only return a value it won't allow you to change the properties of a cell/sheet/workbook. Move your code to a Worksheet_Change event or similar to change properties.
Eg
Private Sub worksheet_change(ByVal target As Range)
target.Font.Bold = True
End Sub
You can create the branch via a hash:
git branch branchname <sha1-of-commit>
Or by using a symbolic reference:
git branch branchname HEAD~3
To checkout the branch when creating it, use
git checkout -b branchname <sha1-of-commit or HEAD~3>
Make sure you switch to default content before switching to frame:
driver.switchTo().defaultContent();
driver.switchTo().frame(x);
x
can be the frame number or you can do a driver.findlement
and use any of the options you have available eg: driver.findElementByName("Name")
.
Here is a non-jQuery solution. Note you can't just use .click()
as some browsers do not support it.
<script type="text/javascript">
function performClick(elemId) {
var elem = document.getElementById(elemId);
if(elem && document.createEvent) {
var evt = document.createEvent("MouseEvents");
evt.initEvent("click", true, false);
elem.dispatchEvent(evt);
}
}
</script>
<a href="#" onclick="performClick('theFile');">Open file dialog</a>
<input type="file" id="theFile" />
var ie = !-[1,]; // true if IE less than 9
This hack is supported in ie5,6,7,8. It is fixed in ie9+ (so it suits demands of this question). This hack works in all IE compatibility modes.
How it works: ie engine treat array with empty element (like this [,1]) as array with two elements, instead other browsers think that there is only one element. So when we convert this array to number with + operator we do something like that: (',1' in ie / '1' in others)*1 and we get NaN in ie and 1 in others. Than we transform it to boolean and reverse value with !. Simple. By the way we can use shorter version without ! sign, but value will be reversed.
This is the shortest hack by now. And I am the author ;)
file is not defined in Python3, which you are using apparently. The package you're instaling is not suitable for Python 3, instead, you should install Python 2.7 and try again.

I needed to exclude an auditing @Aspect @Component from the app context but only for a few test classes. I ended up using @Profile("audit") on the aspect class; including the profile for normal operations but excluding it (don't put it in @ActiveProfiles) on the specific test classes.
Didn't see the answer that worked for me, so here it is: On my OSX system I found yarn at ~/.yarn/bin/yarn
. rm -rf ~/.yarn
took care of it.
How about this:
replace((space(3 - len(MyField))
3 is the number of zeros
to pad
