Removing only decimal part can be done as follows:
number.replace(/(\.\d+)+/,'');
This would convert 13.6667px into 13px (leaving units px untouched).
Various components of SQL Server (Data, Logs, SSAS, SSIS, etc) have a default directory. The setting for this can be found in the registry. Read more here:
http://technet.microsoft.com/en-us/library/ms143547%28SQL.90%29.aspx
So if you created a database using just CREATE DATABASE MyDatabaseName
it would be created at the path specified in one of the settings above.
Now, if the admin / installer changed the default path, then the default path for the instance is stored in the registry at
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SQL Server\[INSTANCENAME]\Setup
If you know the name of the instance then you can query the registry. This example is SQL 2008 specific - let me know if you need the SQL2005 path as well.
DECLARE @regvalue varchar(100)
EXEC master.dbo.xp_regread @rootkey='HKEY_LOCAL_MACHINE',
@key='SOFTWARE\Microsoft\Microsoft SQL Server\MSSQL10.MSSQLServer\Setup',
@value_name='SQLDataRoot',
@value=@regvalue OUTPUT,
@output = 'no_output'
SELECT @regvalue as DataAndLogFilePath
Each database can be created overriding the server setting in a it's own location when you issue the CREATE DATABASE DBName
statement with the appropriate parameters. You can find that out by executing sp_helpdb
exec sp_helpdb 'DBName'
Mini tip:
I had the following scenario:
<a href="/page/">My link text
:after
</a>
I hided the text with font-size: 0, so I could use a FontAwesome icon for it. This worked on Chrome 36, Firefox 31 and IE9+.
I wouldn't recommend color: transparent because the text stil exists and is selectable. Using line-height: 0px didn't allow me to use :after. Maybe because my element was a inline-block.
Visibility: hidden: Didn't allow me to use :after.
text-indent: -9999px;: Also moved the :after element
i simply had to run spotlight search and execute the Docker application under /Applications folder which brew cask install
created. Once this was run it asked to complete installation. I was then able to run docker ps
Had the same problem. This worked for me -
$('selector').once().click(function() {});
Hope this helps someone.
I post you a piece of code which show a way how to solve the problem. As exemple I'm reading a file. You could use this method for another operation, but you need to implements the kill() method so that the main operation will be interrupted.
hope it helps

In my situation I've been using :uuid

I have a patch that I've used in a Rails 4.1 app to let me continue using the legacy key generator (and hence backwards session compatibility with Rails 3), by allowing the secret_key_base to be blank.
Rails::Application.class_eval do
# the key_generator will then use ActiveSupport::LegacyKeyGenerator.new(config.secret_token)
fail "I'm sorry, Dave, there's no :validate_secret_key_config!" unless instance_method(:validate_secret_key_config!)
def validate_secret_key_config! #:nodoc:
config.secret_token = secrets.secret_token
if config.secret_token.blank?
raise "Missing `secret_token` for '#{Rails.env}' environment, set this value in `config/secrets.yml`"
end
end
end
I've since reformatted the patch are submitted it to Rails as a Pull Request
To save hours of coding time, use a jquery plug-in already optimized for embedded video iframes.
I spent a couple days trying to integrate Vimeo's moogaloop API with jquery tools unsuccessfully. See this list for a handful of easier options.
For Python2.7(windows32) I installed only pywin32-223. And I wrote simple python`s code:
import win32api
import time
import win32con
# simulate the pressing-DOWN "ARROW key" of 200 times
for i in range(200):
time.sleep(0.5)
win32api.keybd_event(0x28, 0,0,0)
time.sleep(.05)
win32api.keybd_event(0x28,0 ,win32con.KEYEVENTF_KEYUP ,0)
It can be checked if you run the code and immediately go to the notepad window (where the text already exists) and place the cursor on the top line.

If someone wants to implement using directives then, identify (or create) a div in the index.html (just under the body tag, or at same DOM level)
<div class="google-analytics"/>
and then add the following code in the directive
myApp.directive('googleAnalytics', function ( $location, $window ) {
return {
scope: true,
link: function (scope) {
scope.$on( '$routeChangeSuccess', function () {
$window._gaq.push(['_trackPageview', $location.path()]);
});
}
};
});
Very simple way in codeigniter to call a method of one controller to other controller
1. Controller A
class A extends CI_Controller {
public function __construct()
{
parent::__construct();
}
function custom_a()
{
}
}
2. Controller B
class B extends CI_Controller {
public function __construct()
{
parent::__construct();
}
function custom_b()
{
require_once(APPPATH.'controllers/a.php'); //include controller
$aObj = new a(); //create object
$aObj->custom_a(); //call function
}
}
I used these two commands and saved my problem

Adding a PATH definition into the user crontab with correct values will help... I've filled mine with this line on top (after comments, and before cron jobs):
PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
And it's enough to get all my scripts working... Include any custom path there if you need to.
these solutions are more faster (about 11%) than using numel
;)
for idx = reshape(array,1,[]),

The timing information that this post has referenced is incorrect and inaccurate due to a fundamental typo that was made (see comments stream below as well as the edit history - specifically look at the first version of this answer). Caveat Emptor.
I am not too sure I would go and use an enum as a full fledged class - this is an object oriented language, and one of the most basic tenets of object orientation is that a class should do one thing and do it well.
An enum is doing a pretty good job at being an enum, and a class is doing a good job as a class. Mixing the two I have a feeling will get you into trouble - for example, you can't pass an instance of an enum as a parameter to a method, primarily because you can't create an instance of an enum.
So, even though you might be able to enum.process() does not mean that you should.
In easy language, both versions are absolutely the same. Only difference is:
min.js is for websites (online)
.js is for developers, guys who needs to read, learn about or/and understand jquery codes, for ie plugin development (offline, local work).
Sublime CodeFormatter has formatting support for PHP, JavaScript/JSON/JSONP, HTML, CSS, Python. Although I haven't used CodeFormatter for very long, I have been impressed with it's JS, HTML, and CSS "beautifying" capabilities. I haven't tried using it with PHP (I don't do any PHP development) or Python (which I have no experience with) but both languages have many options in the .sublime-settings
file.
One note however, the settings aren't very easy to find. On Windows you will need to go to your %AppData%\Roaming\Sublime Text #\Packages\CodeFormatter\CodeFormatter.sublime-settings
. As I don't have a Mac I'm not sure where the settings file is on OS X.
As for a shortcut key, I added this key binding to my "Key Bindings - User
" file:
{
"keys": ["ctrl+k", "ctrl+d"],
"command": "code_formatter"
}
I use Ctrl + K, Ctrl + D because that's what Visual Studio uses for formatting. You can change it, of course, just remember that what you choose might conflict with some other feature's keyboard shortcut.
Update:
It seems as if the developers of Sublime Text CodeFormatter have made it easier to access the .sublime-settings
file. If you install CodeFormatter with the Package Control plugin, you can access the settings via the Preferences -> Package Settings -> CodeFormatter -> Settings - Default
and override those settings using the Preferences -> Package Settings -> CodeFormatter -> Settings - User
menu item.
XmlDocument.Attributes
perhaps? (Which has a method GetNamedItem that will presumably do what you want, although I've always just iterated the attribute collection)

You are right, the documentation lacks of those methods. However when I dug into rxjs repository, I found nice comments about tap (too long to paste here) and pipe operators:
/**
* Used to stitch together functional operators into a chain.
* @method pipe
* @return {Observable} the Observable result of all of the operators having
* been called in the order they were passed in.
*
* @example
*
* import { map, filter, scan } from 'rxjs/operators';
*
* Rx.Observable.interval(1000)
* .pipe(
* filter(x => x % 2 === 0),
* map(x => x + x),
* scan((acc, x) => acc + x)
* )
* .subscribe(x => console.log(x))
*/
Pipe: Used to stitch together functional operators into a chain. Before we could just do observable.filter().map().scan()
, but since every RxJS operator is a standalone function rather than an Observable's method, we need pipe()
to make a chain of those operators (see example above).
Tap: Can perform side effects with observed data but does not modify the stream in any way. Formerly called do()
. You can think of it as if observable was an array over time, then tap()
would be an equivalent to Array.forEach()
.
I believe I have found a better solution. The idea to change the function to python universal function (see documentation), which can exercise parallel computation under the hood.
One can write his own customised ufunc
in C, which surely is more efficient, or by invoking np.frompyfunc
, which is built-in factory method. After testing, this is more efficient than np.vectorize
:
f = lambda x, y: x * y
f_arr = np.frompyfunc(f, 2, 1)
vf = np.vectorize(f)
arr = np.linspace(0, 1, 10000)
%timeit f_arr(arr, arr) # 307ms
%timeit f_arr(arr, arr) # 450ms
I have also tested larger samples, and the improvement is proportional. For comparison of performances of other methods, see this post
A straightforward approach:
def round_time(dt, round_to_seconds=60):
"""Round a datetime object to any number of seconds
dt: datetime.datetime object
round_to_seconds: closest number of seconds for rounding, Default 1 minute.
"""
rounded_epoch = round(dt.timestamp() / round_to_seconds) * round_to_seconds
rounded_dt = datetime.datetime.fromtimestamp(rounded_epoch).astimezone(dt.tzinfo)
return rounded_dt
The straight answer is already in a duplicate question: Why does the jquery change event not trigger when I set the value of a select using val()?
As you probably know setting the value of the select doesn't trigger the change() event, if you're looking for an event that is fired when an element's value has been changed through JS there isn't one.
If you really want to do this I guess the only way is to write a function that checks the DOM on an interval and tracks changed values, but definitely don't do this unless you must (not sure why you ever would need to)
Added this solution:
Another possible solution would be to create your own .val()
wrapper function and have it trigger a custom event after setting the value through .val()
, then when you use your .val() wrapper to set the value of a <select>
it will trigger your custom event which you can trap and handle.
Be sure to return this
, so it is chainable in jQuery fashion
You can also use INT_MAX:
http://www.cplusplus.com/reference/climits/
it's equivalent to using numeric_limits.
One could install Git for Windows and subsequently run ssh-add
:
Step 3: Add your key to the ssh-agent
To configure the ssh-agent program to use your SSH key:
If you have GitHub for Windows installed, you can use it to clone repositories and not deal with SSH keys. It also comes with the Git Bash tool, which is the preferred way of running git commands on Windows.
Ensure ssh-agent is enabled:
If you are using Git Bash, turn on ssh-agent:
# start the ssh-agent in the background ssh-agent -s # Agent pid 59566
If you are using another terminal prompt, such as msysgit, turn on ssh-agent:
# start the ssh-agent in the background eval $(ssh-agent -s) # Agent pid 59566
Add your SSH key to the ssh-agent:
ssh-add ~/.ssh/id_rsa
Just use resize: none
textarea {
resize: none;
}
You can also decide to resize your textareas only horizontal or vertical, this way:
textarea { resize: vertical; }
textarea { resize: horizontal; }
Finally,
resize: both
enables the resize grabber.
This works for me. I'm using Identity 2.0, it looks like GetApplicationUser isn't there anymore.
var user = await UserManager.FindByIdAsync(User.Identity.GetUserId());
if (!string.IsNullOrEmpty(form["FirstName"]))
{
user.FirstName = form["FirstName"];
}
if (!string.IsNullOrEmpty(form["LastName"]))
{
user.LastName = form["LastName"];
}
IdentityResult result = await UserManager.UpdateAsync(user);
Since Nov 17, 2015 you have to authenticate users to make any (even such as "get some pictures who have specific hashtag") requests. See the Instagram Platform Changelog:
Apps created on or after Nov 17, 2015: All API endpoints require a valid access_token. Apps created before Nov 17, 2015: Unaffected by new API behavior until June 1, 2016.
this makes now all answers given here before June 1, 2016 no longer useful.

In your link function, do this:
// link function
function (scope, element, attrs) {
var myEl = angular.element(element[0].querySelector('.list-scrollable'));
}
Also, in your link function, don't name your scope
variable using a $
. That is an angular convention that is specific to built in angular services, and is not something that you want to use for your own variables.
By default git revert
refuses to revert a merge commit as what that actually means is ambiguous. I presume that your HEAD
is in fact a merge commit.
If you want to revert the merge commit, you have to specify which parent of the merge you want to consider to be the main trunk, i.e. what you want to revert to.
Often this will be parent number one, for example if you were on master
and did git merge unwanted
and then decided to revert the merge of unwanted
. The first parent would be your pre-merge master
branch and the second parent would be the tip of unwanted
.
In this case you could do:
git revert -m 1 HEAD
This worked for me:
jQuery('#tblPaging').dataTable({
"sort": true,

Simplest and most flexible solution so far it to use table display
:
HTML, left div comes first, right div comes second ... we read and write left to right, so it won't make any sense to place the divs right to left
<div class="container">
<div class="left">
left content flexible width
</div>
<div class="right">
right content fixed width
</div>
</div>
CSS:
.container {
display: table;
width: 100%;
}
.left {
display: table-cell;
width: (whatever you want: 100%, 150px, auto)
}??
.right {
display: table-cell;
width: (whatever you want: 100%, 150px, auto)
}
Cases examples:
// One div is 150px fixed width ; the other takes the rest of the width
.left {width: 150px} .right {width: 100%}
// One div is auto to its inner width ; the other takes the rest of the width
.left {width: 100%} .right {width: auto}
Depending on your exact requirements, you may do best with a jagged array of sorts with:
List<string>[] results = new { new List<string>(), new List<string>() };
Or you may do well with a list of lists or some other such construct.
Here is another option
$array = [1=>'one', 2=>'two', 3=>'there'];
$array = array_flip($array);
echo $array['one'];
You can calculate the checksum of a file by reading the binary data and using hashlib.md5().hexdigest()
. A function to do this would look like the following:
def File_Checksum_Dis(dirname):
if not os.path.exists(dirname):
print(dirname+" directory is not existing");
for fname in os.listdir(dirname):
if not fname.endswith('~'):
fnaav = os.path.join(dirname, fname);
fd = open(fnaav, 'rb');
data = fd.read();
fd.close();
print("-"*70);
print("File Name is: ",fname);
print(hashlib.md5(data).hexdigest())
print("-"*70);
you didn't complete your try
statement. You need and except
in there too.
@import("/path-to-your-styles.css");
That is the best way to include a css stylesheet within a css stylesheet using css.
To print to any printer on the network you can send a PJL/PCL print job directly to a network printer on port 9100.
Please have a look at the below link that should give a good start:
http://frank.zinepal.com/printing-directly-to-a-network-printer
Also, If there is a way to call Windows cmd you can use FTP put to print your page on 9100. Below link should give you details, I have used this method for HP printers but I believe it will work for other printers.

In case, like me, none of the above worked for you, I figured out a very stupid solution.
I'm using a HTC One X on a 2011 Macbook Pro. I just disabled NFC in Settings > Wireless & Networks > More > NFC and viola! Working normally.
For Xamarin.iOS you can use the following code to get contents of the file if file exists.
var documents = Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments);
var filename = Path.Combine(documents, "xyz.json");
if (File.Exists(filename))
{
var text =System.IO.File.ReadAllText(filename);
}
Assuming I understand what you mean:
If your UserControl
is in a library you can add this to you Toolbox using
Toolbox -> right click -> Choose Items -> Browse
Select your assembly with the UserControl
.
If the UserControl
is part of your project you only need to build the entire solution. After that, your UserControl
should appear in the toolbox.
In general, it is not possible to add a Control from Solution Explorer, only from the Toolbox.
The $.getJSON() method does an HTTP GET and not POST. You need to use $.post()
$.post(url, dataToBeSent, function(data, textStatus) {
//data contains the JSON object
//textStatus contains the status: success, error, etc
}, "json");
In that call, dataToBeSent
could be anything you want, although if are sending the contents of a an html form, you can use the serialize method to create the data for the POST from your form.
var dataToBeSent = $("form").serialize();
This happens because your click
handler fires before the value of the radio button changes. You need to listen to the change
event instead:
<input
type="radio"
name="optionsRadios"
id="optionsRadios2"
value=""
v-model="srStatus"
v-on:change="foo"> //here
Also, make sure you really want to call foo()
on ready... seems like maybe you don't actually want to do that.
ready:function(){
foo();
},

I came to this question but it turned out my problem was that I was using setInterval when I should have been using the angular $interval provider. This is also the case for setTimeout (use $timeout instead). I know it's not the answer to the OP's question, but it might help some, as it helped me.
One of the best approach if you do not want to return any columns from table2
is to use the NOT EXISTS
SELECT table1.id
FROM table1 T1
WHERE
NOT EXISTS (SELECT *
FROM table2 T2
WHERE T1.id = T2.user_one
OR T1.id = T2.user_two)
Semantically this says what you want to query: Select every row where there is no matching record in the second table.
MySQL is optimized for EXISTS
: It returns as soon as it finds the first matching record.
Have you heard of Duff's device? This is a great example of using switch fallthrough.
It's a feature that can be used and it can be abused, like almost all language features.
I am storing the date as 'DD-MON-YYYY format (10-Jun-2016) and below query works for me to search records between 2 dates.
select date, substr(date,8,11) || '-' || substr(date,4,4) || substr(date, 1,2), case
substr(date, 4,3)
when 'Jan' then strftime('%s', replace(substr(date,8,11) || '-' || substr(date,4,4) || substr(date, 1,2), 'Jan' , '01'))
when 'Feb' then strftime('%s', replace(substr(date,8,11) || '-' || substr(date,4,4) || substr(date, 1,2), 'Feb' , '02'))
when 'Mar' then strftime('%s', replace(substr(date,8,11) || '-' || substr(date,4,4) || substr(date, 1,2), 'Mar' , '03'))
when 'Apr' then strftime('%s', replace(substr(date,8,11) || '-' || substr(date,4,4) || substr(date, 1,2), 'Apr' , '04'))
when 'May' then strftime('%s', replace(substr(date,8,11) || '-' || substr(date,4,4) || substr(date, 1,2), 'May' , '05'))
when 'Jun' then strftime('%s', replace(substr(date,8,11) || '-' || substr(date,4,4) || substr(date, 1,2), 'Jun' , '06'))
when 'Jul' then strftime('%s', replace(substr(date,8,11) || '-' || substr(date,4,4) || substr(date, 1,2), 'Jul' , '07'))
when 'Aug' then strftime('%s', replace(substr(date,8,11) || '-' || substr(date,4,4) || substr(date, 1,2), 'Aug' , '08'))
when 'Sep' then strftime('%s', replace(substr(date,8,11) || '-' || substr(date,4,4) || substr(date, 1,2), 'Sep' , '09'))

I have no File -> Source Control menu in Visual Studio because I've never used TFS with this installation of Visual Studio.
My problem was I was opening a solution from the internet and the original author had forgotten to remove the TFS bindings, so every time I open the solution I'd get an annoying popup saying
"Go Offline
The Team Foundation Server http://some-other-guys-tfs-server/
is currently unavailable.
The solution will be opened offline."
To get rid of this, I deleted the .suo next to the .sln file, and then opened the .sln file in Notepad and deleted this entire section:
GlobalSection(TeamFoundationVersionControl) = preSolution
SccNumberOfProjects = 2
SccEnterpriseProvider = {xxxxx}
SccTeamFoundationServer = http://some-other-guys-tfs-server/
SccLocalPath0 = .
SccProjectUniqueName1 = xxDemo\\xxDemo.csproj
SccProjectName1 = xxDemo
SccLocalPath1 = xxDemo
EndGlobalSection
Save the .sln in Notepad and then open in Visual Studio, problem solved.
Update: Saveen Reddy has created a tool to do this. I haven't tried it though.
I have found this answer https://stackoverflow.com/a/47107135/3067148 also very helpful:
gradle dependencies
will list the dependencies and download them as a side-effect.
It's poor practice to force the user to do something they don't necessarily want to do. You can't ever really prevent them from closing the browser.
You can achieve a similar effect, though, by making a div
on your current web page to layer over top the rest of your controls so your form is the only thing accessible.

Change .img-responsive inside bootstrap.css to the following:
.img-responsive {
display: block;
max-width: 100%;
width: 100%;
height: auto;
}
For some reason adding width: 100% to the mix makes img-responsive work.
I would use the numpy library, which would allow you to do this for a list of numbers as well:
from numpy import array
a = array([1, 2, 3, 4, 5, 6,])
a[a < 2]
Go to Environmental Variables you will find this in Computer Properties->Advance system Setting->Environmental Variables -> Path
Add the path of your git installed int the system. eg: "C:\Program Files\Git\cmd"
Save it. Good to go now!!
If you are using reflection, you can get the Method object and then:
method.getDeclaringClass().getName()
To get the Method itself, you can probably use:
Class<?> c = Class.forName("class name");
Method method = c.getDeclaredMethod ("method name", parameterTypes)
Install the required version of Windows SDK or change the SDK version in the project property pages

If you do visual studio guide, you will resolve the problem.
I found out that in my version of git bash "2.24.0.windows.2" in my "home" folder under windows users, there will be a file called ".bash-history" with no file extension in that folder. It's only created after you exit from bash.
Here's my workflow:
If you really want points I guess you could make a batch file to do all this but this is good enough for me. Hope it helps someone.
Or you can do it like this!
def skip_elements(elements):
# Initialize variables
new_list = []
i = 0
# Iterate through the list
for words in elements:
# Does this element belong in the resulting list?
if i <= len(elements):
# Add this element to the resulting list
new_list.append(elements[i])
# Increment i
i += 2
return new_list
print(skip_elements(["a", "b", "c", "d", "e", "f", "g"])) # Should be ['a', 'c', 'e', 'g']
print(skip_elements(['Orange', 'Pineapple', 'Strawberry', 'Kiwi', 'Peach'])) # Should be ['Orange', 'Strawberry', 'Peach']
print(skip_elements([])) # Should be []
The easiest way would be to use path.resolve
:
path.resolve(__dirname, '..', '..');
When using
$("#content").load("content.html");
Then remember that you can not "debug" in chrome locally, because XMLHttpRequest cannot load -- This does NOT mean that it does not work, it just means that you need to test your code on same domain aka. your server
Important:
Make sure you're using System.Windows.Media.Brush
and not System.Drawing.Brush
They're not compatible and you'll get binding errors.
The color enumeration you need to use is also different
System.Windows.Media.Colors.Aquamarine (class name isColors
) <--- use this one System.Drawing.Color.Aquamarine (class name isColor
)
If in doubt use Snoop
and inspect the element's background property to look for binding errors - or just look in your debug log.

Ubuntu 16.04 comes with PHP7 as the standard, so there are no PHP5 packages
However if you like you can add a PPA to get those packages anyways:
Remove all the stock php packages
List installed php packages with dpkg -l | grep php| awk '{print $2}' |tr "\n" " "
then remove unneeded packages with sudo aptitude purge your_packages_here or if you want to directly remove them all use :
sudo aptitude purge `dpkg -l | grep php| awk '{print $2}' |tr "\n" " "`
Add the PPA
sudo add-apt-repository ppa:ondrej/php
Install your PHP Version
sudo apt-get update
sudo apt-get install php5.6
You can install php5.6 modules too ..
Verify your version
sudo php -v
Based on https://askubuntu.com/a/756186/532957 (thanks @AhmedJerbi)

Stealth Change in VS 2010 and .NET 4.0 and Later
No public installers with the RunInstallerAttribute.Yes attribute could be found
There is an alias change or compiler cleanup in .NET that may reveal this little tweak for your specific case.
If you have the following code …
RunInstaller(true) // old alias
You may need to update it to
RunInstallerAttribute(true) // new property spelling
It is like an alias changed under the covers at compile time or at runtime and you will get this error behavior. The above explicit change to RunInstallerAttribute(true) fixed it in all of our install scenarios on all machines.
After you add project or service installer then check for the “old” RunInstaller(true) and change it to the new RunInstallerAttribute(true)
You need to configure babel correctly in your project to use export default and export const foo
npm install --save-dev @babel/plugin-proposal-export-default-from
then add below configration in .babelrc
"plugins": [
"@babel/plugin-proposal-export-default-from"
]
Figured it out for myself in the end. It is simple, I was just missing the ** operator to unpack the dictionary
So my example becomes:
d = dict(p1=1, p2=2)
def f2(p1,p2):
print p1, p2
f2(**d)
There is a single quote in $submitsubject
or $submit_message
Why is this a problem?
The single quote char terminates the string in MySQL and everything past that is treated as a sql command. You REALLY don't want to write your sql like that. At best, your application will break intermittently (as you're observing) and at worst, you have just introduced a huge security vulnerability.
Imagine if someone submitted '); DROP TABLE private_messages;
in submit message.
Your SQL Command would be:
INSERT INTO private_messages (to_id, from_id, time_sent, subject, message)
VALUES('sender_id', 'id', now(),'subjet','');
DROP TABLE private_messages;
Instead you need to properly sanitize your values.
AT A MINIMUM you must run each value through mysql_real_escape_string()
but you should really be using prepared statements.
If you were using mysql_real_escape_string()
your code would look like this:
if($_POST['submit_message']){
if($_POST['form_subject']==""){
$submit_subject="(no subject)";
}else{
$submit_subject=mysql_real_escape_string($_POST['form_subject']);
}
$submit_message=mysql_real_escape_string($_POST['form_message']);
$sender_id = mysql_real_escape_string($_POST['sender_id']);
Here is a great article on prepared statements and PDO.
Do not use floats to store fixed-point, accuracy-required data. This example shows how to convert a float to NVARCHAR(50) properly, while also showing why it is a bad idea to use floats for precision data.
create table #f ([Column_Name] float)
insert #f select 9072351234
insert #f select 907235123400000000000
select
cast([Column_Name] as nvarchar(50)),
--cast([Column_Name] as int), Arithmetic overflow
--cast([Column_Name] as bigint), Arithmetic overflow
CAST(LTRIM(STR([Column_Name],50)) AS NVARCHAR(50))
from #f
Output
9.07235e+009 9072351234
9.07235e+020 907235123400000010000
You may notice that the 2nd output ends with '10000' even though the data we tried to store in the table ends with '00000'. It is because float
datatype has a fixed number of significant figures supported, which doesn't extend that far.
When you say
and nope, they don't have attributes: disabled="disabled" or readonly ;-)
Is this through viewing your html, the source code of the page, or the DOM?
If you inspect the DOM with Chrome or Firefox, then you will be able to see any attributes added to the input fields through javasript, or even an overlaying div
// Example: Adding a converter to a column (C#)
Style styleReading = new Style(typeof(TextBlock));
Setter s = new Setter();
s.Property = TextBlock.ForegroundProperty;
Binding b = new Binding();
b.RelativeSource = RelativeSource.Self;
b.Path = new PropertyPath(TextBlock.TextProperty);
b.Converter = new ReadingForegroundSetter();
s.Value = b;
styleReading.Setters.Add(s);
col.ElementStyle = styleReading;
Android changed how permissions work with Android 6.0 that's the reason for your errors. You have to actually request and check if the permission was granted by user to use. So permissions in manifest file will only work for api below 21. Check this link for a snippet of how permissions are requested in api23 http://android-developers.blogspot.nl/2015/09/google-play-services-81-and-android-60.html?m=1
Code:-
If (ActivityCompat.checkSelfPermission(MainActivity.this, Manifest.permission.READ_EXTERNAL_STORAGE) !=
PackageManager.PERMISSION_GRANTED) {
ActivityCompat.requestPermissions(MainActivity.this, new String[]{Manifest.permission.READ_EXTERNAL_STORAGE}, STORAGE_PERMISSION_RC);
return;
}`
` @Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
if (requestCode == STORAGE_PERMISSION_RC) {
if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {
//permission granted start reading
} else {
Toast.makeText(this, "No permission to read external storage.", Toast.LENGTH_SHORT).show();
}
}
}

i use dumpsys to catch if app is crashed and process is still active. situation i used it is to find about remote machine app is crashed or not.
dumpsys | grep myapp | grep "Application Error"
or
adb shell dumpsys | grep myapp | grep Error
or anything that helps...etc
if app is not running you will get nothing as result. When app is stoped messsage is shown on screen by android, process is still active and if you check via "ps" command or anything else, you will see process state is not showing any error or crash meaning. But when you click button to close message, app process will cleaned from process list. so catching crash state without any code in application is hard to find. but dumpsys helps you.

It's easy to achieve this is to just use an Intent like this: (I put the method in a custom class that takes in an Activity as a parameter so it can be called from any Fragment or Activity)
public class UIutils {
private Activity mActivity;
public UIutils(Activity activity){
mActivity = activity;
}
public void showPhoto(Uri photoUri){
Intent intent = new Intent();
intent.setAction(Intent.ACTION_VIEW);
intent.setDataAndType(photoUri, "image/*");
mActivity.startActivity(intent);
}
}
Then to use it just do this:
imageView.setOnClickListener(v1 -> new UIutils(getActivity()).showPhoto(Uri.parse(imageURI)));
I use this with an Image URL but it can be used with stored files as well. If you are accessing images form the phones memory you should use a content provider.
I solved the problem. When I registered the OCX files, I ran it with the Command Window that had been executed as an administrator.
Use the is_user_logged_in
function:
if ( is_user_logged_in() ) {
// your code for logged in user
} else {
// your code for logged out user
}
If you know that you will only have that one querystring variable you can simply do:
var dest = location.search.replace(/^.*?\=/, '');
API keys are just one way of authenticating users of web services.
Arg!!! After playing around either doing this in your Cell

or setting the cell.layoutMargins = UIEdgeInsetsZero;

First of all, you can't pass to alert
second argument, use concatenation instead
alert("Input is " + inputValue);

return { input: '' };_x000D_
},_x000D_
_x000D_

The general syntax, as depicted already is:
std::vector<std::vector<int> > v (A_NUMBER, std::vector <int> (OTHER_NUMBER, DEFAULT_VALUE))
Here, the vector 'v' can be visualised as a two dimensional array, with 'A_NUMBER' of rows, with 'OTHER_NUMBER' of columns with their initial value set to 'DEFAULT_VALUE'.
Also it can be written like this:
std::vector <int> line(OTHER_NUMBER, DEFAULT_VALUE)
std::vector<std::vector<int> > v(A_NUMBER, line)
Inputting values in a 2-D vector is similar to inputting values in a 2-D array:
for(int i = 0; i < A_NUMBER; i++) {
for(int j = 0; j < OTHER_NUMBER; j++) {
std::cin >> v[i][j]
}
}
Examples have already been stated in other answers....!
public class StructMain implements Serializable {
public int id;
public String name;
public String lastName;
}
this my item . implement Serializable and create ArrayList
ArrayList<StructMain> items =new ArrayList<>();
and put in Bundle
Bundle bundle=new Bundle();
bundle.putSerializable("test",items);
and create a new Intent that put Bundle to Intent
Intent intent=new Intent(ActivityOne.this,ActivityTwo.class);
intent.putExtras(bundle);
startActivity(intent);
for receive bundle insert this code
Bundle bundle = getIntent().getExtras();
ArrayList<StructMain> item = (ArrayList<StructMain>) bundle.getSerializable("test");
Use Hosts Commander. It's simple and powerful. Translated description (from russian) here.
hosts add another.dev 192.168.1.1 # Remote host
hosts add test.local # 127.0.0.1 used by default
hosts set myhost.dev # new comment
hosts rem *.local
hosts enable local*
hosts disable localhost
...and many others...
Usage:
hosts - run hosts command interpreter
hosts <command> <params> - execute hosts command
Commands:
add <host> <aliases> <addr> # <comment> - add new host
set <host|mask> <addr> # <comment> - set ip and comment for host
rem <host|mask> - remove host
on <host|mask> - enable host
off <host|mask> - disable host
view [all] <mask> - display enabled and visible, or all hosts
hide <host|mask> - hide host from 'hosts view'
show <host|mask> - show host in 'hosts view'
print - display raw hosts file
format - format host rows
clean - format and remove all comments
rollback - rollback last operation
backup - backup hosts file
restore - restore hosts file from backup
recreate - empty hosts file
open - open hosts file in notepad
An interesting side effect of this causes a problem when starting runnable jar files in the command prompt.
If you try (in a command prompt):
jarfile.jar parameter
No joy, because this is being translated to the following (which doesn't work):
javaw.exe -jar jarfile.jar parameter
However, the following command does work:
java.exe -jar jarfile.jar parameter
If you change the association in file manager as described above to:
"C:\Program Files\Java\j2re1.4.2_04\bin\java.exe" -jar "%1" %*
Then you can type:
jarfile.jar parameter
in the command prompt and it will now work!
EDIT:(However you then get a black console window when you run a form based (non console) Java app, so this is not an ideal solution)
If you run these jar files by double clicking them in windows, no parameters will be passed so your Java code needs to handle the stack overflow exception and include a "press a key" function at the end or the window will just disappear.
In order to pass a parameter in windows you have to create a shortcut to the jar file, which includes the parameter in the target line (right click on the shortcut and select properties) you can not add parameters to the jar file icon itself in this way.
There isn't a single, consistent solution here, but you would have the same problem with any other console application.
There is a windows freeware application called "bat to exe" which you can use to create an exe file from a .bat file with the apropriate command line in it. you can also embed the jar file in the exe with this application, and make it clean it up when it has finished running, so this may be a more elegant solution.

Yes, you can run PHP in an HTML page.
I have successfully executed PHP code in my HTML files for many years. (For the curious, this is because I have over 8,000 static HTML files created by me and others over the last 20 years and I didn't want to lose search engine ranking by changing them and, more importantly, I have too many other things to work on).

To run HTML using FastCGI/PHP, try adding this code to the .htaccess file for the directory the script is in:
Options +ExecCGI
AddHandler fcgid-script .html
FCGIWrapper /usr/local/cpanel/cgi-sys/php5 .html
You can add additional lines for other file extensions if needed.
Another nice little method is to include the current directory in your load path with
$:.unshift('.')
You could push it onto the $: ($LOAD_PATH) array but unshift will force it to load your current working directory before the rest of the load path.
Once you've added your current directory in your load path you don't need to keep specifying
require './tokenizer'
and can just go back to using
require 'tokenizer'
If @Maleki's answer isn't working for you, check and see if you have an .editorconfig
file in your project folder.
For example the Angular CLI generates one with a new project that looks like this
# Editor configuration, see http://editorconfig.org
root = true
[*]
charset = utf-8
indent_style = space
indent_size = 2
insert_final_newline = true
trim_trailing_whitespace = true
[*.md]
max_line_length = off
trim_trailing_whitespace = false
Changing the indent_size
here is required as it seems it will override anything in your .vscode
workspace or user settings.
In your example propertyInfo.GetValue(this, null)
should work. Consider altering GetNamesAndTypesAndValues()
as follows:
public void GetNamesAndTypesAndValues()
{
foreach (PropertyInfo propertyInfo in allClassProperties)
{
Console.WriteLine("{0} [type = {1}] [value = {2}]",
propertyInfo.Name,
propertyInfo.PropertyType,
propertyInfo.GetValue(this, null));
}
}
You can't do this without JavaScript. Stackoverflow is using the jQuery JavaScript library which attachs functions to HTML elements on page load.
Here's how you could do it with vanilla JavaScript:
<textarea onkeydown="if (event.keyCode == 13) { this.form.submit(); return false; }"></textarea>
Keycode 13 is the enter key.
Here's how you could do it with jQuery like as Stackoverflow does:
<textarea class="commentarea"></textarea>
with
$(document).ready(function() {
$('.commentarea').keydown(function(event) {
if (event.which == 13) {
this.form.submit();
event.preventDefault();
}
});
});
Or you can use this:
^(?:part[12]|(part)1,\12)$
The use of http.createClient
is now deprecated. You can pass Headers in options collection as below.
var options = {
hostname: 'example.com',
path: '/somePath.php',
method: 'GET',
headers: {'Cookie': 'myCookie=myvalue'}
};
var results = '';
var req = http.request(options, function(res) {
res.on('data', function (chunk) {
results = results + chunk;
//TODO
});
res.on('end', function () {
//TODO
});
});
req.on('error', function(e) {
//TODO
});
req.end();
The biggest benefit is that the code is more succinct. The VS editor will also have the IntelliSense support that some of the other view engines don't have.
Declarative HTML Helpers also look pretty cool as doing HTML helpers within C# code reminds me of custom controls in ASP.NET. I think they took a page from partials but with the inline code.
So some definite benefits over the asp.net view engine.
With contrast to a view engine like spark though:
Spark is still more succinct, you can keep the if's and loops within a html tag itself. The markup still just feels more natural to me.
You can code partials exactly how you would do a declarative helper, you'd just pass along the variables to the partial and you have the same thing. This has been around with spark for quite awhile.
Go to http://www.anindya.com/php-5-4-3-and-php-5-3-13-x64-64-bit-for-windows/ and download the cURL version that corresponds to your PHP version under "Fixed curl extensions:".
So if you have PHP 5.3.13, download "php_curl-5.3.13-VC9-x64.zip". Try the "VC" version first. Then replace the php_curl.dll in ext folder. This worked for me.
If you mean to create a new form when a button is clicked, the below code may be of some use to you:
private void settingsButton_Click(Object sender, EventArgs e)
{
// Create a new instance of the Form2 class
Form2 settingsForm = new Form2();
// Show the settings form
settingsForm.Show();
}
From here, you could also use the 'Show Dialog' method
data-keyboard="false" data-backdrop="static" in your html code for start of modal Box div
Kyle's solution worked perfectly fine for me so I made my research in order to avoid any Js and CSS, but just sticking with HTML.
Adding a value of selected
to the item we want to appear as a header forces it to show in the first place as a placeholder.
Something like:
<option selected disabled>Choose here</option>
The complete markup should be along these lines:
<select>
<option selected disabled>Choose here</option>
<option value="1">One</option>
<option value="2">Two</option>
<option value="3">Three</option>
<option value="4">Four</option>
<option value="5">Five</option>
</select>
You can take a look at this fiddle, and here's the result:
If you do not want the sort of placeholder text to appear listed in the options once a user clicks on the select box just add the hidden
attribute like so:
<select>
<option selected disabled hidden>Choose here</option>
<option value="1">One</option>
<option value="2">Two</option>
<option value="3">Three</option>
<option value="4">Four</option>
<option value="5">Five</option>
</select>
Check the fiddle here and the screenshot below.
Here is the solution:
<select>
<option style="display:none;" selected>Select language</option>
<option>Option 1</option>
<option>Option 2</option>
</select>
Putty usually comes with the "plink" utility.
This is essentially the "ssh" command line command implemented as a windows .exe.
It pretty well documented in the putty manual under "Using the command line tool plink".
You just need to wrap a command like:
plink root@myserver /etc/backups/do-backup.sh
in a .bat script.
You can also use common shell constructs, like semicolons to execute multiple commands. e.g:
plink read@myhost ls -lrt /home/read/files;/etc/backups/do-backup.sh
for those who are using alphine linux, apk add openldap-dev
After the C# 6.0 (including) you can use nameof expression:
using Stuff = Some.Cool.Functionality
class C {
static int Method1 (string x, int y) {}
static int Method1 (string x, string y) {}
int Method2 (int z) {}
string f<T>() => nameof(T);
}
var c = new C()
nameof(C) -> "C"
nameof(C.Method1) -> "Method1"
nameof(C.Method2) -> "Method2"
nameof(c.Method1) -> "Method1"
nameof(c.Method2) -> "Method2"
nameof(z) -> "z" // inside of Method2 ok, inside Method1 is a compiler error
nameof(Stuff) = "Stuff"
nameof(T) -> "T" // works inside of method but not in attributes on the method
nameof(f) -> “f”
nameof(f<T>) -> syntax error
nameof(f<>) -> syntax error
nameof(Method2()) -> error “This expression does not have a name”
Note! nameof
not get the underlying object's runtime Type, it is just the compile-time argument. If a method accepts an IEnumerable then nameof simply returns "IEnumerable", whereas the actual object could be "List".
Others have mentioned the relevel
command which is the best solution if you want to change the base level for all analyses on your data (or are willing to live with changing the data).
If you don't want to change the data (this is a one time change, but in the future you want the default behavior again), then you can use a combination of the C
(note uppercase) function to set contrasts and the contr.treatments
function with the base argument for choosing which level you want to be the baseline.
For example:
lm( Sepal.Width ~ C(Species,contr.treatment(3, base=2)), data=iris )

Underlying cause:
Content scripts are executed in an "isolated world" environment.
Solution::
To access functions/variables of the page context ("main world") you have to inject the code into the page itself using DOM. Same thing if you want to expose your functions/variables to the page context (in your case it's the state()
method).
Note in case communication with the page script is needed:
Use DOM CustomEvent
handler. Examples: one, two, and three.
Note in case chrome
API is needed in the page script:
Since chrome.*
APIs can't be used in the page script, you have to use them in the content script and send the results to the page script via DOM messaging (see the note above).
Safety warning:
A page may redefine or augment/hook a built-in prototype so your exposed code may fail if the page did it in an incompatible fashion. If you want to make sure your exposed code runs in a safe environment then you should either a) declare your content script with "run_at": "document_start" and use Methods 2-3 not 1, or b) extract the original native built-ins via an empty iframe, example. Note that with document_start
you may need to use DOMContentLoaded
event inside the exposed code to wait for DOM.
This is the easiest/best method when you have lots of code. Include your actual JS code in a file within your extension, say script.js
. Then let your content script be as follows (explained here: Google Chome “Application Shortcut” Custom Javascript):
var s = document.createElement('script');
// TODO: add "script.js" to web_accessible_resources in manifest.json
s.src = chrome.runtime.getURL('script.js');
s.onload = function() {
this.remove();
};
(document.head || document.documentElement).appendChild(s);
Note: For security reasons, Chrome prevents loading of js files. Your file must be added as a "web_accessible_resources"
item (example) :
// manifest.json must include:
"web_accessible_resources": ["script.js"],
If not, the following error will appear in the console:
Denying load of chrome-extension://[EXTENSIONID]/script.js. Resources must be listed in the web_accessible_resources manifest key in order to be loaded by pages outside the extension.
This method is useful when you want to quickly run a small piece of code. (See also: How to disable facebook hotkeys with Chrome extension?).
var actualCode = `// Code here.
// If you want to use a variable, use $ and curly braces.
// For example, to use a fixed random number:
var someFixedRandomValue = ${ Math.random() };
// NOTE: Do not insert unsafe variables in this way, see below
// at "Dynamic values in the injected code"
`;
var script = document.createElement('script');
script.textContent = actualCode;
(document.head||document.documentElement).appendChild(script);
script.remove();
Note: template literals are only supported in Chrome 41 and above. If you want the extension to work in Chrome 40-, use:
var actualCode = ['/* Code here. Example: */' + 'alert(0);',
'// Beware! This array have to be joined',
'// using a newline. Otherwise, missing semicolons',
'// or single-line comments (//) will mess up your',
'// code ----->'].join('\n');
For a big chunk of code, quoting the string is not feasible. Instead of using an array, a function can be used, and stringified:
var actualCode = '(' + function() {
// All code is executed in a local scope.
// For example, the following does NOT overwrite the global `alert` method
var alert = null;
// To overwrite a global variable, prefix `window`:
window.alert = null;
} + ')();';
var script = document.createElement('script');
script.textContent = actualCode;
(document.head||document.documentElement).appendChild(script);
script.remove();
This method works, because the +
operator on strings and a function converts all objects to a string. If you intend on using the code more than once, it's wise to create a function to avoid code repetition. An implementation might look like:
function injectScript(func) {
var actualCode = '(' + func + ')();'
...
}
injectScript(function() {
alert("Injected script");
});
Note: Since the function is serialized, the original scope, and all bound properties are lost!
var scriptToInject = function() {
console.log(typeof scriptToInject);
};
injectScript(scriptToInject);
// Console output: "undefined"
Sometimes, you want to run some code immediately, e.g. to run some code before the <head>
element is created. This can be done by inserting a <script>
tag with textContent
(see method 2/2b).
An alternative, but not recommended is to use inline events. It is not recommended because if the page defines a Content Security policy that forbids inline scripts, then inline event listeners are blocked. Inline scripts injected by the extension, on the other hand, still run. If you still want to use inline events, this is how:
var actualCode = '// Some code example \n' +
'console.log(document.documentElement.outerHTML);';
document.documentElement.setAttribute('onreset', actualCode);
document.documentElement.dispatchEvent(new CustomEvent('reset'));
document.documentElement.removeAttribute('onreset');
Note: This method assumes that there are no other global event listeners that handle the reset
event. If there is, you can also pick one of the other global events. Just open the JavaScript console (F12), type document.documentElement.on
, and pick on of the available events.
Occasionally, you need to pass an arbitrary variable to the injected function. For example:
var GREETING = "Hi, I'm ";
var NAME = "Rob";
var scriptToInject = function() {
alert(GREETING + NAME);
};
To inject this code, you need to pass the variables as arguments to the anonymous function. Be sure to implement it correctly! The following will not work:
var scriptToInject = function (GREETING, NAME) { ... };
var actualCode = '(' + scriptToInject + ')(' + GREETING + ',' + NAME + ')';
// The previous will work for numbers and booleans, but not strings.
// To see why, have a look at the resulting string:
var actualCode = "(function(GREETING, NAME) {...})(Hi, I'm ,Rob)";
// ^^^^^^^^ ^^^ No string literals!
The solution is to use JSON.stringify
before passing the argument. Example:
var actualCode = '(' + function(greeting, name) { ...
} + ')(' + JSON.stringify(GREETING) + ',' + JSON.stringify(NAME) + ')';
If you have many variables, it's worthwhile to use JSON.stringify
once, to improve readability, as follows:
...
} + ')(' + JSON.stringify([arg1, arg2, arg3, arg4]) + ')';
There is a difference between window.innerHeight
and document.documentElement.clientHeight
. The first includes the height of the horizontal scrollbar.
Here's a quick and dirty solution for one, or a few, renamed and modified files that are uncommitted.
Let's say the file was named foo
and now it's named bar
:
Rename bar
to a temp name:
mv bar side
Checkout foo
:
git checkout HEAD foo
Rename foo
to bar
with Git:
git mv foo bar
Now rename your temporary file back to bar
.
mv side bar
This last step is what gets your changed content back into the file.
While this can work, if the moved file is too different in content from the original git will consider it more efficient to decide this is a new object. Let me demonstrate:

This is actually a modified version of the selected answer in order to support Unicode characters but I don't have enough reputation to comment there.
CREATE FUNCTION SPLIT_STRING(str VARCHAR(255) CHARSET utf8, delim VARCHAR(12), pos INT) RETURNS varchar(255) CHARSET utf8
RETURN REPLACE(SUBSTRING(SUBSTRING_INDEX(str, delim, pos),
CHAR_LENGTH(SUBSTRING_INDEX(str, delim, pos-1)) + 1),
delim, '')
The modifications are the following:
utf8
utf8
CHAR_LENGTH()
instead of LENGTH()
to calculate the character length and not the byte length.If you want to show those number values as a time then change the format of the cell to Time.
And if you want to transform it to a text in another cell:
=TEXT(A1,"hh:mm:ss")
You are just supposed to provide the predict
method with the same 2D array, but with one value that you want to process (or more). In short, you can just replace
[0.58,0.76]
With
[[0.58,0.76]]
And it should work.
EDIT: This answer became popular so I thought I'd add a little more explanation about ML. The short version: we can only use predict
on data that is of the same dimensionality as the training data (X
) was.
In the example in question, we give the computer a bunch of rows in X
(with 2 values each) and we show it the correct responses in y
. When we want to predict
using new values, our program expects the same - a bunch of rows. Even if we want to do it to just one row (with two values), that row has to be part of another array.
Basically It is used in HeapOverflows or other reversing type Problems i.e. If you want to change a 64 bit ELF to 32 bit ELF and it is showing error while converting.

The argument is of length zero takes places when you get an output as an integer of length 0 and not a NULL output.i.e., integer(0).
You can further verify my point by finding the class of your output-
>class(output)
"integer"
Highlight the cell(s)/column which you want as Duration, right click on the mouse to "Format Cells". Go to "Custom" and look for "h:mm" if you want to input duration in hour and minutes format. If you want to include seconds as well, click on "h:mm:ss". You can even add up the total duration after that.
Hope this helps.

Such as;
<button type="button" class="btn btn-default" data-dismiss="modal">Send Form</button>
In this scenario, I prefer to create new branches for each issue. I use a prefix temp/ so I know that I can delete these branches later.
git checkout -b temp/bug1
Stage the files that fix bug1 and commit them.
git checkout -b temp/bug2
You can then cherry pick the commits from the respective branches as require and submit a pull request.
You can use %in%
data[data$Code %in% selected,]
Code Value
1 A 1
2 B 2
7 A 3
8 A 4
You can use switch like this:
XML Layout
<RadioGroup
android:id="@+id/RG"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<RadioButton
android:id="@+id/R1"
android:layout_width="wrap_contnet"
android:layout_height="wrap_content"
android:text="R1" />
<RadioButton
android:id="@+id/R2"
android:layout_width="wrap_contnet"
android:layout_height="wrap_content"
android:text="R2" />
</RadioGroup>
And JAVA Activity
switch (RG.getCheckedRadioButtonId()) {
case R.id.R1:
regAuxiliar = ultimoRegistro;
case R.id.R2:
regAuxiliar = objRegistro;
default:
regAuxiliar = null; // none selected
}
You will also need to implement an onClick function with button or setOnCheckedChangeListener function to get required functionality.
In addition to other answers which helped me, you can also add to surrounding div. In my case this was for sign on with user Name/Password fields.
<div (keyup.enter)="login()" class="container-fluid">
Based on 'Google JavaScript Style Guide'
File names must be all lowercase and may include underscores (_) or dashes (-), but no additional punctuation. Follow the convention that your project uses. Filenames’ extension must be .js.
By setting the Visibility of all items in Menu, the appbar menu or overflow menu will be Hide automatically
Example
private Menu menu_change_language;
...
...
@Override
public boolean onCreateOptionsMenu(Menu menu) {
...
...
menu_change_language = menu;
menu_change_language.findItem(R.id.menu_change_language).setVisible(true);
return super.onCreateOptionsMenu(menu);
}
Before going to other fragment use bellow code:
if(menu_change_language != null){
menu_change_language.findItem(R.id.menu_change_language)
.setVisible(false);
}
I had similar problem except that it happened without installing any plugin. I begin to get this dialog about source control every time I open the project + tons of windows popping up and floating which I had to close one by one.
Windows -> Rest Windows Layout, fixed it for me without any problems. It does bring the default setting which I don't mind at all :)
you can use the return
statement without any parameter to exit a function
def foo(element):
do something
if check is true:
do more (because check was succesful)
else:
return
do much much more...
or raise an exception if you want to be informed of the problem
def foo(element):
do something
if check is true:
do more (because check was succesful)
else:
raise Exception("cause of the problem")
do much much more...
Here's yet another way to skin this cat, using a dictionary to map new values onto the keys in the list:
def map_values(row, values_dict):
return values_dict[row]
values_dict = {'A': 1, 'B': 2, 'C': 3, 'D': 4}
df = pd.DataFrame({'INDICATOR': ['A', 'B', 'C', 'D'], 'VALUE': [10, 9, 8, 7]})
df['NEW_VALUE'] = df['INDICATOR'].apply(map_values, args = (values_dict,))
What's it look like:
df
Out[2]:
INDICATOR VALUE NEW_VALUE
0 A 10 1
1 B 9 2
2 C 8 3
3 D 7 4
This approach can be very powerful when you have many ifelse
-type statements to make (i.e. many unique values to replace).
And of course you could always do this:
df['NEW_VALUE'] = df['INDICATOR'].map(values_dict)
But that approach is more than three times as slow as the apply
approach from above, on my machine.
And you could also do this, using dict.get
:
df['NEW_VALUE'] = [values_dict.get(v, None) for v in df['INDICATOR']]
In SBT 0.13 and above, you can use the sbtVersion
task (as pointed out by @steffen) or about
command (as pointed out by @mark-harrah)
There's a difference how the sbtVersion
task works in and outside a SBT project. When in a SBT project, sbtVersion
displays the version of SBT used by the project and its subprojects.

There are 2 Reasons why we have to Normalize Input Features before Feeding them to Neural Network:
Reason 1: If a Feature
in the Dataset
is big in scale compared to others then this big scaled feature becomes dominating and as a result of that, Predictions of the Neural Network will not be Accurate.
Example: In case of Employee Data, if we consider Age and Salary, Age will be a Two Digit Number while Salary can be 7 or 8 Digit (1 Million, etc..). In that Case, Salary will Dominate the Prediction of the Neural Network. But if we Normalize those Features, Values of both the Features will lie in the Range from (0 to 1).
Reason 2: Front Propagation of Neural Networks involves the Dot Product of Weights with Input Features. So, if the Values are very high (for Image and Non-Image Data), Calculation of Output takes a lot of Computation Time as well as Memory. Same is the case during Back Propagation. Consequently, Model Converges slowly, if the Inputs are not Normalized.
Example: If we perform Image Classification, Size of Image will be very huge, as the Value of each Pixel ranges from 0 to 255. Normalization in this case is very important.
Mentioned below are the instances where Normalization is very important:
To check an ajax request you can use if (Request::ajax())
Note: If you are using laravel 5, then in the controller replace
use Illuminate\Http\Request;
with
use Request;
I hope it'll work.
Personally, one of the things I love about python is the tuple-dict combination. What you have here is effectively a 2d array (where x = fruit name and y = color), and I am generally a supporter of the dict of tuples for implementing 2d arrays, at least when something like numpy
or a database isn't more appropriate. So in short, I think you've got a good approach.
Note that you can't use dicts as keys in a dict without doing some extra work, so that's not a very good solution.
That said, you should also consider namedtuple(). That way you could do this:
>>> from collections import namedtuple
>>> Fruit = namedtuple("Fruit", ["name", "color"])
>>> f = Fruit(name="banana", color="red")
>>> print f
Fruit(name='banana', color='red')
>>> f.name
'banana'
>>> f.color
'red'
Now you can use your fruitcount dict:
>>> fruitcount = {Fruit("banana", "red"):5}
>>> fruitcount[f]
5
Other tricks:
>>> fruits = fruitcount.keys()
>>> fruits.sort()
>>> print fruits
[Fruit(name='apple', color='green'),
Fruit(name='apple', color='red'),
Fruit(name='banana', color='blue'),
Fruit(name='strawberry', color='blue')]
>>> fruits.sort(key=lambda x:x.color)
>>> print fruits
[Fruit(name='banana', color='blue'),
Fruit(name='strawberry', color='blue'),
Fruit(name='apple', color='green'),
Fruit(name='apple', color='red')]
Echoing chmullig, to get a list of all colors of one fruit, you would have to filter the keys, i.e.
bananas = [fruit for fruit in fruits if fruit.name=='banana']
Someone should mention that in the question there is a little trap. #ifdef
will only check if the following symbol has been defined via #define
or by command line, but its value (its substitution in fact) is irrelevant. You could even write
#define one
precompilers accept that.
But if you use #if
it's another thing.
#define one 0
#if one
printf("one evaluates to a truth ");
#endif
#if !one
printf("one does not evaluate to truth ");
#endif
will give one does not evaluate to truth
. The keyword defined
allows to get the desired behaviour.
#if defined(one)
is therefore equivalent to #ifdef
The advantage of the #if
construct is to allow a better handling of code paths, try to do something like that with the old #ifdef
/#ifndef
pair.
#if defined(ORA_PROC) || defined(__GNUC) && __GNUC_VERSION > 300
The safest way IMO is to point at the file in your run/debug config
-Dlog4j.configuration=file:mylogging.properties
! Be aware: when using the eclipse launch configurations the specification of the file:
protocol is mandatory.
In this way the logger will not catch any logging.properties that come before in the classpath nor the default one in the JDK.
Also, consider actually use the log4j.xml which has a richer expression syntax and will allow more things (log4j.xml tahe precedence over log4j.properties.
try this:
$("#mydate").datepicker("setDate",'1d');
You can set a default style for the entire workbook (all worksheets):
$objPHPExcel->getDefaultStyle()
->getBorders()
->getTop()
->setBorderStyle(PHPExcel_Style_Border::BORDER_THIN);
$objPHPExcel->getDefaultStyle()
->getBorders()
->getBottom()
->setBorderStyle(PHPExcel_Style_Border::BORDER_THIN);
$objPHPExcel->getDefaultStyle()
->getBorders()
->getLeft()
->setBorderStyle(PHPExcel_Style_Border::BORDER_THIN);
$objPHPExcel->getDefaultStyle()
->getBorders()
->getRight()
->setBorderStyle(PHPExcel_Style_Border::BORDER_THIN);
or
$styleArray = array(
'borders' => array(
'allborders' => array(
'style' => PHPExcel_Style_Border::BORDER_THIN
)
)
);
$objPHPExcel->getDefaultStyle()->applyFromArray($styleArray);
And this can be used for all style properties, not just borders.
But column autosizing is structural
rather than stylistic
, and has to be set for each column on each worksheet individually.
EDIT
Note that default workbook style only applies to Excel5 Writer
I managed to find network.http.connect.timeout for much older versions of Mozilla:
This preference was one of several added to allow low-level tweaking of the HTTP networking code. After a portion of the same code was significantly rewritten in 2001, the preference ceased to have any effect (as noted in all.js as early as September 2001).
Currently, the timeout is determined by the system-level connection establishment timeout. Adding a way to configure this value is considered low-priority.
It would seem that network.http.connect.timeout
hasn't done anything for some time.
I also saw references to network.http.request.timeout
, so I did a Google search. The results include lots of links to people recommending that others include it in about:config
in what appears to be a mistaken belief that it actually does something, since the same search turns up this about:config entries article:
Pref removed (unused). Previously: HTTP-specific network timeout. Default value is 120.
The same page includes additional information about network.http.connect.timeout
:
Pref removed (unused). Previously: determines how long to wait for a response until registering a timeout. Default value is 30.
Disclaimer: The information on the MozillaZine Knowledge Base may be incorrect, incomplete or out-of-date.

i was looking for some string bits conversion and got here, If the next case is for you take //it so... if you want to use the bits from a string into different bits maybe this example would help
$string="1001"; //this would be 2^0*1+....0...+2^3*1=1+8=9

$bit3=$string[1];
$bit2=$string[2];
$bit1=$string[3];//1
If you've tried all the solutions above and still doesn't resolve your issue.
This might not seemed related, but here's my take on it.
Try removing this from your Gradle dependency, I've spend 2 hours of my time because of this roadblock.
implementation "com.squareup.retrofit2:adapter-rxjava2:2.3.0"
Given points (X1,Y1) and (X2,Y2) then:

The easiest solution for the selected option in dropdown using PHP is following
<select class="form-control" name="currency_selling" required >
<option value="">Select Currency</option>
<option value="pkr" <?=$selected_currency == 'pkr' ? ' selected="selected"' : '';?> >PKR</option>
<option value="dollar" <?=$selected_currency == 'dollar' ? ' selected="selected"' : '';?> >USD</option>
<option value="pounds" <?=$selected_currency == 'pounds' ? ' selected="selected"' : '';?> >POUNDS</option>
<option value="dirham" <?=$selected_currency == 'dirham' ? ' selected="selected"' : '';?> >DRHM</option>
</select>
If you want to use numpy, you must define darr
to be a numpy array, not a list
:
import numpy as np
darr = np.array([1, 3.14159, 1e100, -2.71828])
print(darr.min())
darr.argmin()
will give you the index corresponding to the minimum.
The reason you were getting an error is because argmin
is a method understood by numpy arrays, but not by Python lists
.
I previously had this problem with my EC2 instance (I was serving couchdb to serve resources -- am considering Amazon's S3 for the future).
One thing to check (assuming Ec2) is that the couchdb port is added to your open ports within your security policy.
I specifically encountered
"[Errno 111] Connection refused"
over EC2 when the instance was stopped and started. The problem seems to be a pidfile race. The solution for me was killing couchdb (entirely and properly) via:
pkill -f couchdb
and then restarting with:
/etc/init.d/couchdb restart
You could use the ArrayUtils API to remove it in a "nice looking way". It implements many operations (remove, find, add, contains,etc) on Arrays.
Take a look. It has made my life simpler.
Simplest solution: The Oracle client is not installed on the remote server where the SSIS package is being executed.
Slightly less simple solution: The Oracle client is installed on the remote server, but in the wrong bit-count for the SSIS installation. For example, if the 64-bit Oracle client is installed but SSIS is being executed with the 32-bit dtexec
executable, SSIS will not be able to find the Oracle client.
The solution in this case would be to install the 32-bit Oracle client side-by-side with the 64-bit client.
There's no easy way (in terms of performance) to do what you want to do.
Reflection works with assemblys and types mainly so you'll have to get all the types of the assembly and query them for the right interface. Here's an example:
Assembly asm = Assembly.Load("MyAssembly");
Type[] types = asm.GetTypes();
Type[] result = types.where(x => x.GetInterface("IMyInterface") != null);
That will get you all the types that implement the IMyInterface in the Assembly MyAssembly
You may have to perform a diff and put document.getElementById('name')
code inside a condition, in case your component is something like this:
// using the new hooks API
function Comp(props) {
const { isLoading, data } = props;
useEffect(() => {
if (data) {
var name = document.getElementById('name').value;
}
}, [data]) // this diff is necessary
if (isLoading) return <div>isLoading</div>
return (
<div id='name'>Comp</div>
);
}
If diff is not performed then, you will get null
.
There`s my solution. It will compare arrays which also have objects and arrays. Elements can be stay in any positions. Example:
const array1 = [{a: 1}, {b: 2}, { c: 0, d: { e: 1, f: 2, } }, [1,2,3,54]];
const array2 = [{a: 1}, {b: 2}, { c: 0, d: { e: 1, f: 2, } }, [1,2,3,54]];
const arraysCompare = (a1, a2) => {
if (a1.length !== a2.length) return false;
const objectIteration = (object) => {
const result = [];
const objectReduce = (obj) => {
for (let i in obj) {
if (typeof obj[i] !== 'object') {
result.push(`${i}${obj[i]}`);
} else {
objectReduce(obj[i]);
}
}
};
objectReduce(object);
return result;
};
const reduceArray1 = a1.map(item => {
if (typeof item !== 'object') return item;
return objectIteration(item).join('');
});
const reduceArray2 = a2.map(item => {
if (typeof item !== 'object') return item;
return objectIteration(item).join('');
});
const compare = reduceArray1.map(item => reduceArray2.includes(item));
return compare.reduce((acc, item) => acc + Number(item)) === a1.length;
};
console.log(arraysCompare(array1, array2));
Though using find
command can be useful here, the shell itself provides options to achieve this requirement without any third party tools. The bash
shell provides an extended glob support option using which you can get the file names under recursive paths that match with the extensions you want.
The extended option is extglob
which needs to be set using the shopt
option as below. The options are enabled with the -s
support and disabled with he -u
flag. Additionally you could use couple of options more i.e. nullglob
in which an unmatched glob is swept away entirely, replaced with a set of zero words. And globstar
that allows to recurse through all the directories
shopt -s extglob nullglob globstar
Now all you need to do is form the glob expression to include the files of a certain extension which you can do as below. We use an array to populate the glob results because when quoted properly and expanded, the filenames with special characters would remain intact and not get broken due to word-splitting by the shell.
For example to list all the *.csv
files in the recursive paths
fileList=(**/*.csv)
The option **
is to recurse through the sub-folders and *.csv
is glob expansion to include any file of the extensions mentioned. Now for printing the actual files, just do
printf '%s\n' "${fileList[@]}"
Using an array and doing a proper quoted expansion is the right way when used in shell scripts, but for interactive use, you could simply use ls
with the glob expression as
ls -1 -- **/*.csv
This could very well be expanded to match multiple files i.e. file ending with multiple extension (i.e. similar to adding multiple flags in find
command). For example consider a case of needing to get all recursive image files i.e. of extensions *.gif
, *.png
and *.jpg
, all you need to is
ls -1 -- **/+(*.jpg|*.gif|*.png)
This could very well be expanded to have negate results also. With the same syntax, one could use the results of the glob to exclude files of certain type. Assume you want to exclude file names with the extensions above, you could do
excludeResults=()
excludeResults=(**/!(*.jpg|*.gif|*.png))
printf '%s\n' "${excludeResults[@]}"
The construct !()
is a negate operation to not include any of the file extensions listed inside and |
is an alternation operator just as used in the Extended Regular Expressions library to do an OR match of the globs.
Note that these extended glob support is not available in the POSIX bourne shell and its purely specific to recent versions of bash
. So if your are considering portability of the scripts running across POSIX and bash
shells, this option wouldn't be right.
This way optimizes for readability, but it's not as efficient in terms of database queries:
# Retrieve all topics, then use array subtraction to
# find the ones not in our list
Topic.all - @forums.map(&:id)

If you wanted to quickly create a new object to hold some data about a book. You would do something like this:
$book = new stdClass;
$book->title = "Harry Potter and the Prisoner of Azkaban";
$book->author = "J. K. Rowling";
$book->publisher = "Arthur A. Levine Books";
$book->amazon_link = "http://www.amazon.com/dp/0439136369/";
Please check the site - http://www.webmaster-source.com/2009/08/20/php-stdclass-storing-data-object-instead-array/ for more details.
It's actually something that can be done using a combination of the current stack-trace data, and reflection.
public void MyMethod()
{
StackTrace stackTrace = new System.Diagnostics.StackTrace();
StackFrame frame = stackTrace.GetFrames()[1];
MethodInfo method = frame.GetMethod();
string methodName = method.Name;
Type methodsClass = method.DeclaringType;
}
The 1
index on the StackFrame
array will give you the method which called MyMethod
You can use the CSS3 Linear Gradient property along with your background-image like this:
#landing-wrapper {
display:table;
width:100%;
background: linear-gradient( rgba(0, 0, 0, 0.5), rgba(0, 0, 0, 0.5) ), url('landingpagepic.jpg');
background-position:center top;
height:350px;
}
Here's a demo:
#landing-wrapper {_x000D_
display: table;_x000D_
width: 100%;_x000D_
background: linear-gradient(rgba(0, 0, 0, 0.5), rgba(0, 0, 0, 0.5)), url('http://placehold.it/350x150');_x000D_
background-position: center top;_x000D_

}
_x000D_

Yes, we can run docker in docker, we'll need to attach the unix sockeet "/var/run/docker.sock" on which the docker daemon listens by default as volume to the parent docker using "-v /var/run/docker.sock:/var/run/docker.sock". Sometimes, permissions issues may arise for docker daemon socket for which you can write "sudo chmod 757 /var/run/docker.sock".
And also it would require to run the docker in privileged mode, so the commands would be:
sudo chmod 757 /var/run/docker.sock
docker run --privileged=true -v /var/run/docker.sock:/var/run/docker.sock -it ...
As with all technologies, it has its ups and downs. If you are using an iframe to get around a properly developed site, then of course it is bad practice. However sometimes an iframe is acceptable.
One of the main problems with an iframe has to do with bookmarks and navigation. If you are using it to simply embed a page inside your content, I think that is fine. That is what an iframe is for.
However I've seen iframes abused as well. It should never be used as an integral part of your site, but as a piece of content within a site.
Usually, if you can do it without an iframe, that is a better option. I'm sure others here may have more information or more specific examples, it all comes down to the problem you are trying to solve.
With that said, if you are limited to HTML and have no access to a backend like PHP or ASP.NET etc, sometimes an iframe is your only option.

One easy way to select random items is to shuffle then slice.
import random
a = [1,2,3,4,5,6,7,8,9]
random.shuffle(a)
print a[:4] # prints 4 random variables
The Date constructor accepts any value. If the primitive [[value]] of the argument is number, then the Date that is created has that value. If primitive [[value]] is String, then the specification only guarantees that the Date constructor and the parse method are capable of parsing the result of Date.prototype.toString and Date.prototype.toUTCString()
A reliable way to set a Date is to construct one and use the setFullYear
and setTime
methods.
An example of that appears here: http://jibbering.com/faq/#parseDate
ECMA-262 r3 does not define any date formats. Passing string values to the Date constructor or Date.parse has implementation-dependent outcome. It is best avoided.
YYYY-MM-DD
can be parsed to a Date
with the following:-
/**Parses string formatted as YYYY-MM-DD to a Date object.
* If the supplied string does not match the format, an

You can easily convert miliseconds into seconds, minutes and hours.
val millis = **milliSecondsYouWantToConvert**
val seconds = (millis / 1000) % 60
val minutes = ((millis / 1000) / 60) % 60
val hours = ((millis / 1000) / 60) / 60
println("--------------------------------------------------------------------")
println(String.format("%02dh : %02dm : %02ds remaining", hours, minutes, seconds))
println("--------------------------------------------------------------------")
**RESULT :**
--------------------------------------------------------------------
01h : 23m : 37s remaining
--------------------------------------------------------------------
@erikkallen is close but not quite right.
theta_rad = atan2(y,x);
theta_deg = (theta_rad/M_PI*180) + (theta_rad > 0 ? 0 : 360);
This should work in C++: (depending on how fmod is implemented, it may be faster or slower than the conditional expression)
theta_deg = fmod(atan2(y,x)/M_PI*180,360);
Alternatively you could do this:
theta_deg = atan2(-y,-x)/M_PI*180 + 180;
since (x,y) and (-x,-y) differ in angles by 180 degrees.
Check your keystore file for first, in you example you creating file with name my-release-key.keystore. If its correct and really present in folder Users/bournewang/Documents/Project
check alias, in your example it is -alias alias_name, but in config you specified alias mike
The answers above were all assuming your Python distribution would have some third-party libraries in order to achieve the "one liner python ftpd" goal, but that is not the case of what @zio was asking. Also, SimpleHTTPServer involves web broswer for downloading files, it's not quick enough.
Python can't do ftpd by itself, but you can use netcat, nc
:
nc
is basically a built-in tool from any UNIX-like systems (even embedded systems), so it's perfect for "quick and temporary way to transfer files".
Step 1, on the receiver side, run:
nc -l 12345 | tar -xf -
this will listen on port 12345, waiting for data.
Step 2, on the sender side:
tar -cf - ALL_FILES_YOU_WANT_TO_SEND ... | nc $RECEIVER_IP 12345
You can also put pv
in the middle to monitor the progress of transferring:
tar -cf - ALL_FILES_YOU_WANT_TO_SEND ...| pv | nc $RECEIVER_IP 12345
After the transferring is finished, both sides of nc
will quit automatically, and job done.
The simplest way to get row counts per group is by calling .size()
, which returns a Series
:
df.groupby(['col1','col2']).size()
Usually you want this result as a DataFrame
(instead of a Series
) so you can do:
df.groupby(['col1', 'col2']).size().reset_index(name='counts')
If you want to find out how to calculate the row counts and other statistics for each group continue reading below.
Consider the following example dataframe:
In [2]: df
Out[2]:
col1 col2 col3 col4 col5 col6
0 A B 0.20 -0.61 -0.49 1.49
1 A B -1.53 -1.01 -0.39 1.82
2 A B -0.44 0.27 0.72 0.11
3 A B 0.28 -1.32 0.38 0.18
4 C D 0.12 0.59 0.81 0.66
5 C D -0.13 -1.65 -1.64 0.50
6 C D -1.42 -0.11 -0.18 -0.44
7 E F -0.00 1.42 -0.26 1.17
8 E F 0.91 -0.47 1.35 -0.34
9 G H 1.48 -0.63 -1.14 0.17
First let's use .size()
to get the row counts:
In [3]: df.groupby(['col1', 'col2']).size()
Out[3]:
col1 col2
A B 4
C D 3
E F 2
G H 1
dtype: int64
Then let's use .size().reset_index(name='counts')
to get the row counts:
In [4]: df.groupby(['col1', 'col2']).size().reset_index(name='counts')
Out[4]:
col1 col2 counts
0 A B 4
1 C D 3
2 E F 2
3 G H 1
When you want to calculate statistics on grouped data, it usually looks like this:
In [5]: (df
...: .groupby(['col1', 'col2'])
...: .agg({
...: 'col3': ['mean', 'count'],
...: 'col4': ['median', 'min', 'count']
...: }))
Out[5]:
col4 col3
median min count mean count
col1 col2
A B -0.810 -1.32 4 -0.372500 4
C D -0.110 -1.65 3 -0.476667 3
E F 0.475 -0.47 2 0.455000 2
G H -0.630 -0.63 1 1.480000 1
The result above is a little annoying to deal with because of the nested column labels, and also because row counts are on a per column basis.
To gain more control over the output I usually split the statistics into individual aggregations that I then combine using join
. It looks like this:
In [6]: gb = df.groupby(['col1', 'col2'])
...: counts = gb.size().to_frame(name='counts')
...: (counts
...: .join(gb.agg({'col3': 'mean'}).rename(columns={'col3': 'col3_mean'}))
...: .join(gb.agg({'col4': 'median'}).rename(columns={'col4': 'col4_median'}))
...: .join(gb.agg({'col4': 'min'}).rename(columns={'col4': 'col4_min'}))
...: .reset_index()
...: )
...:
Out[6]:
col1 col2 counts col3_mean col4_median col4_min
0 A B 4 -0.372500 -0.810 -1.32
1 C D 3 -0.476667 -0.110 -1.65
2 E F 2 0.455000 0.475 -0.47
3 G H 1 1.480000 -0.630 -0.63
The code used to generate the test data is shown below:
In [1]: import numpy as np
...: import pandas as pd
...:
...: keys = np.array([
...: ['A', 'B'],
...: ['A', 'B'],
...: ['A', 'B'],
...: ['A', 'B'],
...: ['C', 'D'],
...: ['C', 'D'],
...: ['C', 'D'],
...: ['E', 'F'],
...: ['E', 'F'],
...: ['G', 'H']
...: ])
...:
...: df = pd.DataFrame(
...: np.hstack([keys,np.random.randn(10,4).round(2)]),
...: columns = ['col1', 'col2', 'col3', 'col4', 'col5', 'col6']
...: )
...:
...: df[['col3', 'col4', 'col5', 'col6']] = \
...: df[['col3', 'col4', 'col5', 'col6']].astype(float)
...:
Disclaimer:
If some of the columns that you are aggregating have null values, then you really want to be looking at the group row counts as an independent aggregation for each column. Otherwise you may be misled as to how many records are actually being used to calculate things like the mean because pandas will drop NaN
entries in the mean calculation without telling you about it.
There is Task
exists, It is unnesscery using BackgroundWorker
, Task
is more simple. for example:
ProgressDialog.cs:
public partial class ProgressDialog : Form
{
public System.Windows.Forms.ProgressBar Progressbar { get { return this.progressBar1; } }
public ProgressDialog()
{
InitializeComponent();
}
public void RunAsync(Action action)
{
Task.Run(action);
}
}
Done! Then you can reuse ProgressDialog anywhere:
var progressDialog = new ProgressDialog();
progressDialog.Progressbar.Value = 0;
progressDialog.Progressbar.Maximum = 100;
progressDialog.RunAsync(() =>
{
for (int i = 0; i < 100; i++)
{
Thread.Sleep(1000)
this.progressDialog.Progressbar.BeginInvoke((MethodInvoker)(() => {
this.progressDialog.Progressbar.Value += 1;
}));
}
});
progressDialog.ShowDialog();
My modified support library supports using both View animations (i.e. <translate>, <rotate>
) and Object Animators (i.e. <objectAnimator>
) for Fragment Transitions. It is implemented with NineOldAndroids. Refer to my documentation on github for details.
You can use this:
Collections.sort(list, org.joda.time.DateTimeComparator.getInstance());
If someone wants expandable/collapsible version of the treeview from Vitaliy Bychik's answer, you can save some time :)
http://jsfiddle.net/mehmetatas/fXzHS/2/
$(function () {
$('.tree li').hide();
$('.tree li:first').show();
$('.tree li').on('click', function (e) {
var children = $(this).find('> ul > li');
if (children.is(":visible")) children.hide('fast');
else children.show('fast');
e.stopPropagation();
});
});
Here I will show you that how you can make a phone call from your activity. To make a call you have to put down this code in your app.
try {
Intent my_callIntent = new Intent(Intent.ACTION_CALL);
my_callIntent.setData(Uri.parse("tel:"+phn_no));
//here the word 'tel' is important for making a call...
startActivity(my_callIntent);
} catch (ActivityNotFoundException e) {
Toast.makeText(getApplicationContext(), "Error in your phone call"+e.getMessage(), Toast.LENGTH_LONG).show();
}
You should use a foreach loop, like this:
public static IEnumerable<int> StringToIntList(string str) {
if (String.IsNullOrEmpty(str))
yield break;
foreach(var s in str.Split(',')) {
int num;
if (int.TryParse(s, out num))
yield return num;
}
}
Note that like your original post, this will ignore numbers that couldn't be parsed.
If you want to throw an exception if a number couldn't be parsed, you can do it much more simply using LINQ:
return (str ?? "").Split(',').Select<string, int>(int.Parse);
[OOT]
A bit OOT, but this question is the most closest topic with my question.
Here is an example if you want to show Event where ALL participant meet certain requirement. Let's say, event where ALL the participant has fully paid. So, it WILL NOT return events which having one or more participants that haven't fully paid .
Simply use the whereDoesntHave
of the others 2 statuses.
Let's say the statuses are haven't paid at all [eq:1], paid some of it [eq:2], and fully paid [eq:3]
Event::whereDoesntHave('participants', function ($query) {
return $query->whereRaw('payment = 1 or payment = 2');
})->get();

I finally found the answer for 2019. You need to add 'IIS APPPOOL\DefaultAppPool' to the list of users that have security rights to the directory that is to be modified. Make sure they have full rights.
You need to set a height on the DIV. Otherwise it will keep expanding indefinitely.
Remember if you are starting the server from a service, it will start a different bash session so the ulimit won't be effective there. Try to put this in your script itself:
ulimit -c unlimited
It's the implementations that doesn't support multi-threading. Currently Google Gears is providing a way to use some form of concurrency by executing external processes but that's about it.
The new browser Google is supposed to release today (Google Chrome) executes some code in parallel by separating it in process.
The core language, of course can have the same support as, say Java, but support for something like Erlang's concurrency is nowhere near the horizon.
You'll need to keep the current value of the input in state (or pass changes in its value up to a parent via a callback function, or sideways, or <your app's state management solution here> such that it eventually gets passed back into your component as a prop) so you can derive the disabled prop for the button.
Example using state:
<meta charset="UTF-8">_x000D_
<script src="https://fb.me/react-0.13.3.js"></script>_x000D_
<script src="https://fb.me/JSXTransformer-0.13.3.js"></script>_x000D_
<div id="app"></div>_x000D_
<script type="text/jsx;harmony=true">void function() { "use strict";_x000D_
_x000D_
var App = React.createClass({_x000D_
getInitialState() {_x000D_
return {email: ''}_x000D_
},_x000D_
handleChange(e) {_x000D_
this.setState({email: e.target.value})_x000D_
},_x000D_
render() {_x000D_
return <div>_x000D_
<input name="email" value={this.state.email} onChange={this.handleChange}/>_x000D_
<button type="button" disabled={!this.state.email}>Button</button>_x000D_
</div>_x000D_
}_x000D_
})_x000D_
_x000D_
React.render(<App/>, document.getElementById('app'))_x000D_
_x000D_
}()</script>

ldapConnection is the server adres: ldap.example.com Ldap.Connection.Path is the path inside the ADS that you like to use insert in LDAP format.
OU=Your_OU,OU=other_ou,dc=example,dc=com
You start at the deepest OU working back to the root of the AD, then add dc=X for every domain section until you have everything including the top level domain
Now i miss a parameter to authenticate, this works the same as the path for the username
CN=username,OU=users,DC=example,DC=com
Check to see if the Andriod Device is installed on PC. See steps below. The 'Other device' will change to 'Andriod Device' once the USB drive is installed. The browse path should be \extras\google\usb_driver\ not the sub directories under it. Otherwise the installation will not find the package.
To install the Android USB driver on Windows 7 for the first time:
Connect your Android-powered device to your computer's USB port. Right-click on Computer from your desktop or Windows Explorer, and select Manage. Select Devices in the left pane. Locate and expand Other device in the right pane. Right-click the device name (such as Nexus S) and select Update Driver Software. This will launch the Hardware Update Wizard. Select Browse my computer for driver software and click Next. Click Browse and locate the USB driver folder. (The Google USB Driver is located in \extras\google\usb_driver.) Click Next to install the driver.
from PHP manual:
str_replace — Replace all occurrences of the search string with the replacement string
I would go down that route, and then convert from string to float - floatval
This happens quite very often to me.
Last time that happened I can remembered was caused by switching the Eclipse ADT (Google special edition) to Android Studio, and switching back. I basically tried all methods that I can found on stackoverflow which didn't work for me.
Eventually, I got the app working again (no more NoCalssDeffoundError) by switching my IDE to original Eclipse (Kepler) with ADT.
The or
operator returns the first operand if it is true, otherwise the second operand. So in your case your test is equivalent to if name == "Jesse"
.
The correct application of or
would be:
if (name == "Jesse") or (name == "jesse"):
You can add this in Post Model,
public function categories()
{
return $this->belongsToMany('App\Category','category_post','post_id','category_id');
}
category_post
indicate the table you want to use.
post_id
indicate the column where you want to store the posts id.
category_id
indicate the column where you want to store the categories id.
Here is Bjarne Stroustrup's wordings,
In C++, the definition of NULL is 0, so there is only an aesthetic difference. I prefer to avoid macros, so I use 0. Another problem with NULL is that people sometimes mistakenly believe that it is different from 0 and/or not an integer. In pre-standard code, NULL was/is sometimes defined to something unsuitable and therefore had/has to be avoided. That's less common these days.
If you have to name the null pointer, call it nullptr; that's what it's called in C++11. Then, "nullptr" will be a keyword.

You can use Apache commons-io for this task:
Refer to this method:
public static byte[] readFileToByteArray(File file) throws IOException
Update:
Java 7 way:
byte[] bytes = Files.readAllBytes(Paths.get(filename));
and if it is a text file and you want to convert it to String (change encoding as needed):
StandardCharsets.UTF_8.decode(ByteBuffer.wrap(bytes)).toString()
