I found a way to change the Application Output theme and everything that can't be edited from .css
.
If you use osX:
string dirpath = Directory.GetCurrentDirectory();
Prepend this dirpath to the filename to get the complete path.
As @Dan Puzey indicated in the comments, it would be better to use Path.Combine
Path.Combine(Directory.GetCurrentDirectory(), filename)
If all that's needed is to send html code inline in the code, we can use below
var app = express();
app.get('/test.html', function (req, res) {
res.header('Content-Type', 'text/html').send("<html>my html code</html>");
});
as others said Calendar.MONTH returns int and is zero indexed.
to get the current month as a String
use SimpleDateFormat.format()
method
Calendar cal = Calendar.getInstance();
System.out.println(new SimpleDateFormat("MMM").format(cal.getTime()));
returns NOV
The relational database uses a formal system of predicates to address data. The underlying physical implementation is of no substance and can vary to optimize for certain operations, but it must always assume the relational model. In layman's terms, that's just saying I know exactly how many values (attributes) each row (tuple) in my table (relation) has and now I want to exploit the fact accordingly, thoroughly and to it's extreme. That's the true nature of the beast.
Since we're obviously the generation that has had a relational upbringing, if you look at NoSQL database models from the perspective of the relational model, again in layman's terms, the first obvious difference is that no assumptions about the number of values a row can contain is ever made. This is really oversimplifying the matter and does not cleanly apply to the intricacies of the physical models of every NoSQL database, but it's the pinnacle of the relational model and the first assumption we have to leave behind or, if you'd rather, the biggest leap we have to make.
We can agree to two things that are true for every DBMS: it can store any kind of data and has enough mathematical underpinnings to make it possible to manage the data in any way imaginable. The reality is that you'll never want to make the mistake of putting any of the two points to the test, but rather just stick with what the actual DBMS was really made for. In layman's terms: respect the beast within!
(Please note that I've avoided comparing the (obviously) well founded standards revolving around the relational model against the many flavors provided by NoSQL databases. If you'd like, consider NoSQL databases as an umbrella term for any DBMS that does not completely assume the relational model, in exclusion to everything else. The differences are too many, but that's the principal difference and the one I think would be of most use to you to understand the two.)
$computer,$Speed,$Regcheck
will create an array, and run out-file
ones per variable = they get seperate lines. If you construct a single string using the variables first, it will show up a single line. Like this:
"$computer,$Speed,$Regcheck" | out-file -filepath C:\temp\scripts\pshell\dump.txt -append -width 200
Use git archive branch-index | tar -x -C your-folder-on-PC
to clone a branch to another folder. I think, then you can copy any file that you need
Return is how you exit out of a function body. You are using the correct approach.
I suppose, depending on how your application is structured, you could also use throw. That would typically require that your calls to your function are wrapped in a try / catch block.
The problem is that you forgot to import os. Add this line of code:
import os
And everything should be fine. Hope this helps!
We make sure we are working with a clean workspace by using a feature of the git plugin. You can add additional behaviors like 'Clean before checkout'. We use this as well for 'Prune stale remote-tracking branches'.
mkdir [-switch] foldername
-p
is a switch which is optional, it will create subfolder and parent folder as well even parent folder doesn't exist.
From the man page:
-p, --parents no error if existing, make parent directories as needed
Example:
mkdir -p storage/framework/{sessions,views,cache}
This will create subfolder sessions,views,cache inside framework folder irrespective of 'framework' was available earlier or not.
this query return last record for every Form_id:
SELECT m1.*
FROM messages m1 LEFT JOIN messages m2
ON (m1.Form_id = m2.Form_id AND m1.id < m2.id)
WHERE m2.id IS NULL;
Assuming you have GNU find:
find . -size +10000k -printf '%s %f\n'
If you want a constant width for the size field, you can do something like:
find . -size +10000k -printf '%10s %f\n'
Note that -size +1000k
selects files of at least 10,240,000 bytes (k
is 1024, not 1000). You said in a comment that you want files bigger than 1M; if that's 1024*1024 bytes, then this:
find . -size +1M ...
will do the trick -- except that it will also print the size and name of files that are exactly 1024*1024 bytes. If that matters, you could use:
find . -size +1048575c ...
You need to decide just what criterion you want.
Here is my solution. Works in most browsers
document.getElementById("scrollHere").scrollIntoView({behavior: "smooth"});
document.getElementById("end").scrollIntoView({behavior: "smooth"});
_x000D_
body {margin: 0px; display: block; height: 100%; background-image: linear-gradient(red, yellow);}_x000D_
.start {display: block; margin: 100px 10px 1000px 0px;}_x000D_
.end {display: block; margin: 0px 0px 100px 0px;}
_x000D_
<div class="start">Start</div>_x000D_
<div class="end" id="end">End</div>
_x000D_
if only 1 row, you can use join
Select t1.Col1, t1.Col2, t1.Col3, t2.Col4, t2.Col5 from Table1 t1 join Table2 t2;
I found a straight forward way of solving this, with the use of JSON.parse.
Let's assume the json below is inside the variable jsontext.
[
["Blankaholm", "Gamleby"],
["2012-10-23", "2012-10-22"],
["Blankaholm. Under natten har det varit inbrott", "E22 i med Gamleby. Singelolycka. En bilist har.],
["57.586174","16.521841"], ["57.893162","16.406090"]
]
The solution is this:
var parsedData = JSON.parse(jsontext);
Now I can access the elements the following way:
var cities = parsedData[0];
example : 1 and 2 table is available
1 table delete entry and select nor 2 table records and insert to no 1 table . when delete time no 1 table dont have second table records example emp id not available means this errors appeared
Solution with backward compatibility:
SEL requestSelector = NSSelectorFromString(@"requestWhenInUseAuthorization");
if ([CLLocationManager authorizationStatus] == kCLAuthorizationStatusNotDetermined &&
[self.locationManager respondsToSelector:requestSelector]) {
[self.locationManager performSelector:requestSelector withObject:NULL];
} else {
[self.locationManager startUpdatingLocation];
}
Setup NSLocationWhenInUseUsageDescription key in your Info.plist
A PHP array or object or other complex data structure cannot be transported or stored or otherwise used outside of a running PHP script. If you want to persist such a complex data structure beyond a single run of a script, you need to serialize it. That just means to put the structure into a "lower common denominator" that can be handled by things other than PHP, like databases, text files, sockets. The standard PHP function serialize
is just a format to express such a thing, it serializes a data structure into a string representation that's unique to PHP and can be reversed into a PHP object using unserialize
. There are many other formats though, like JSON or XML.
Take for example this common problem:
PHP and Javascript can only communicate via strings. You can pass the string "foo"
very easily to Javascript. You can pass the number 1
very easily to Javascript. You can pass the boolean values true
and false
easily to Javascript. But how do you pass this array to Javascript?
Array ( [1] => elem 1 [2] => elem 2 [3] => elem 3 )
The answer is serialization. In case of PHP/Javascript, JSON is actually the better serialization format:
{ 1 : 'elem 1', 2 : 'elem 2', 3 : 'elem 3' }
Javascript can easily reverse this into an actual Javascript array.
This is just as valid a representation of the same data structure though:
a:3:{i:1;s:6:"elem 1";i:2;s:6:"elem 2";i:3;s:7:" elem 3";}
But pretty much only PHP uses it, there's little support for this format anywhere else.
This is very common and well supported as well though:
<array>
<element key='1'>elem 1</element>
<element key='2'>elem 2</element>
<element key='3'>elem 3</element>
</array>
There are many situations where you need to pass complex data structures around as strings. Serialization, representing arbitrary data structures as strings, solves how to do this.
I was getting the same error when i switched to STS version 3.8.3 And imported my entire workspace to the new STS.
Apparently the "Boot Spring App" instance was defective. (i run from STS)
If this is your problem, Simply create the Boot run configuration again.
Add return false to the end of your click handler, this prevents the browser default handler occurring which attempts to redirect the page:
$('a').click(function() {
// do stuff
return false;
});
javascript:document.getElementsByClassName("video-stream html5-main-video")[0].playbackRate = 0.1;
you can put any number here just don't go to far so you don't overun your computer.
You can use following technique to dynamically load JS scripts and libraries on demand in your Angular project.
script.store.ts will contain the path of the script either locally or on a remote server and a name that will be used to load the script dynamically
interface Scripts {
name: string;
src: string;
}
export const ScriptStore: Scripts[] = [
{name: 'filepicker', src: 'https://api.filestackapi.com/filestack.js'},
{name: 'rangeSlider', src: '../../../assets/js/ion.rangeSlider.min.js'}
];
script.service.ts is an injectable service that will handle the loading of script, copy script.service.ts
as it is
import {Injectable} from "@angular/core";
import {ScriptStore} from "./script.store";
declare var document: any;
@Injectable()
export class ScriptService {
private scripts: any = {};
constructor() {
ScriptStore.forEach((script: any) => {
this.scripts[script.name] = {
loaded: false,
src: script.src
};
});
}
load(...scripts: string[]) {
var promises: any[] = [];
scripts.forEach((script) => promises.push(this.loadScript(script)));
return Promise.all(promises);
}
loadScript(name: string) {
return new Promise((resolve, reject) => {
//resolve if already loaded
if (this.scripts[name].loaded) {
resolve({script: name, loaded: true, status: 'Already Loaded'});
}
else {
//load script
let script = document.createElement('script');
script.type = 'text/javascript';
script.src = this.scripts[name].src;
if (script.readyState) { //IE
script.onreadystatechange = () => {
if (script.readyState === "loaded" || script.readyState === "complete") {
script.onreadystatechange = null;
this.scripts[name].loaded = true;
resolve({script: name, loaded: true, status: 'Loaded'});
}
};
} else { //Others
script.onload = () => {
this.scripts[name].loaded = true;
resolve({script: name, loaded: true, status: 'Loaded'});
};
}
script.onerror = (error: any) => resolve({script: name, loaded: false, status: 'Loaded'});
document.getElementsByTagName('head')[0].appendChild(script);
}
});
}
}
Inject this ScriptService
wherever you need it and load js libs like this
this.script.load('filepicker', 'rangeSlider').then(data => {
console.log('script loaded ', data);
}).catch(error => console.log(error));
You have to do the following:
a=a.replace("\n"," ");
a=a.trim();
String b[]=a.split("+");
int k=Integer.ValueOf(b[0]);
int l=Integer.ValueOf(b[1]);
int sum=k+l;
Create a link in /var/www/html
like this to fix the error:
sudo ln -s /usr/share/phpmyadmin /var/www/html
# This script fragment emits Cygwin rulez under bash/cygwin
if [[ $(uname -s) == CYGWIN* ]];then
echo Cygwin rulez
else
echo Unix is king
fi
If the 6 first chars of uname -s command is "CYGWIN", a cygwin system is assumed
Just use the . at the end of the git clone
command (being in that directory), like this:
cd your_dir_to_clone_in/
git clone [email protected]/somerepo/ .
After "AND" and after "OR" the QUERY has forgotten what it is all about.
I would also not know that it is about in any SQL / programming language.
if(SOMETHING equals "X" or SOMETHING equals "Y")
COLUMN NOT LIKE "A%" AND COLUMN NOT LIKE "B%"
How and where is
app.run()
used? After module definition or afterapp.config()
, afterapp.controller()
?
In your package.js E.g. /packages/dashboard/public/controllers/dashboard.js
Make it look like this
var app = angular.module('mean.dashboard', ['ui.bootstrap']);
app.controller('DashboardController', ['$scope', 'Global', 'Dashboard',
function($scope, Global, Dashboard) {
$scope.global = Global;
$scope.package = {
name: 'dashboard'
};
// ...
}
]);
app.run(function(editableOptions) {
editableOptions.theme = 'bs3'; // bootstrap3 theme. Can be also 'bs2', 'default'
});
Today (2.5 years after this answer) you can safely use Array.forEach
. As @ricosrealm suggests, decodeURIComponent
was used in this function.
function getJsonFromUrl(url) {
if(!url) url = location.search;
var query = url.substr(1);
var result = {};
query.split("&").forEach(function(part) {
var item = part.split("=");
result[item[0]] = decodeURIComponent(item[1]);
});
return result;
}
actually it's not that simple, see the peer-review in the comments, especially:
=
(@AndrewF)+
(added by me)For further details, see MDN article and RFC 3986.
Maybe this should go to codereview SE, but here is safer and regexp-free code:
function getJsonFromUrl(url) {
if(!url) url = location.href;
var question = url.indexOf("?");
var hash = url.indexOf("#");
if(hash==-1 && question==-1) return {};
if(hash==-1) hash = url.length;
var query = question==-1 || hash==question+1 ? url.substring(hash) :
url.substring(question+1,hash);
var result = {};
query.split("&").forEach(function(part) {
if(!part) return;
part = part.split("+").join(" "); // replace every + with space, regexp-free version
var eq = part.indexOf("=");
var key = eq>-1 ? part.substr(0,eq) : part;
var val = eq>-1 ? decodeURIComponent(part.substr(eq+1)) : "";
var from = key.indexOf("[");
if(from==-1) result[decodeURIComponent(key)] = val;
else {
var to = key.indexOf("]",from);
var index = decodeURIComponent(key.substring(from+1,to));
key = decodeURIComponent(key.substring(0,from));
if(!result[key]) result[key] = [];
if(!index) result[key].push(val);
else result[key][index] = val;
}
});
return result;
}
This function can parse even URLs like
var url = "?foo%20e[]=a%20a&foo+e[%5Bx%5D]=b&foo e[]=c";
// {"foo e": ["a a", "c", "[x]":"b"]}
var obj = getJsonFromUrl(url)["foo e"];
for(var key in obj) { // Array.forEach would skip string keys here
console.log(key,":",obj[key]);
}
/*
0 : a a
1 : c
[x] : b
*/
Your compiler may have a warning that it can generate if a base class function becomes hidden. If it does, enable it. That will catch const clashes and differences in parameter lists. Unfortunately this won't uncover a spelling error.
For example, this is warning C4263 in Microsoft Visual C++.
C programmers use the static attribute to hide variable and function declarations inside modules, much as you would use public and private declarations in Java and C++. C source files play the role of modules. Any global variable or function declared with the static attribute is private to that module. Similarly, any global variable or function declared without the static attribute is public and can be accessed by any other module. It is good programming practice to protect your variables and functions with the static attribute wherever possible.
You will have to use Array.find
or Array.filter
or Array.forEach
.
Since you value is array and you need position of element, you will have to iterate over it.
var data = [{"name":"placeHolder","section":"right"},{"name":"Overview","section":"left"},{"name":"ByFunction","section":"left"},{"name":"Time","section":"left"},{"name":"allFit","section":"left"},{"name":"allbMatches","section":"left"},{"name":"allOffers","section":"left"},{"name":"allInterests","section":"left"},{"name":"allResponses","section":"left"},{"name":"divChanged","section":"right"}];
var index = -1;
var val = "allInterests"
var filteredObj = data.find(function(item, i){
if(item.name === val){
index = i;
return i;
}
});
console.log(index, filteredObj);
_x000D_
var data = [{"name":"placeHolder","section":"right"},{"name":"Overview","section":"left"},{"name":"ByFunction","section":"left"},{"name":"Time","section":"left"},{"name":"allFit","section":"left"},{"name":"allbMatches","section":"left"},{"name":"allOffers","section":"left"},{"name":"allInterests","section":"left"},{"name":"allResponses","section":"left"},{"name":"divChanged","section":"right"}];
var val = "allInterests"
var index = data.findIndex(function(item, i){
return item.name === val
});
console.log(index);

Default Array.indexOf()
will match searchValue to current element and not its properties. You can refer Array.indexOf - polyfill on MDN
another method:
@echo off
for /f "useback delims=" %%_ in (%0) do (
if "%%_"=="___ATAD___" set $=
if defined $ echo(%%_
if "%%_"=="___DATA___" set $=1
)

I was facing this problem when trying to add a .NETStandard dependency to a .NET4.6.1 library, and compiling it in Linux with Mono 4.6.2 (the version that comes with Ubuntu 16.04).
I finally solved it today; the solution requires to do both of these things:
<TargetFrameworkVersion>v4.6.1</TargetFrameworkVersion>
to <TargetFrameworkVersion>v4.7.1</TargetFrameworkVersion>
in the .csproj file.You couldn't login because you did't get proper solt text at login time. There are two options, first is define static salt, second is if you want create dynamic salt than you have to store the salt somewhere (means in database) with associate with user. Than you concatenate user solt+password_hash string now with this you fire query with username in your database table.
Truth be told there are many, many resources explaining how to do this already out on the web:
Git: how to reverse-merge a commit?
Git: how to reverse-merge a commit?
Undoing Merges, from Git's blog (retrieved from archive.org's Wayback Machine)
So I guess I'll just summarize some of these:
git revert <merge commit hash>
This creates an extra "revert" commit saying you undid a merge
git reset --hard <commit hash *before* the merge>
This reset history to before you did the merge. If you have commits after the merge you will need to cherry-pick
them on to afterwards.
But honestly this guide here is better than anything I can explain, with diagrams! :)
You can use multiselect
function for this.
CriteriaBuilder cb=session.getCriteriaBuilder();
CriteriaQuery<Object[]> cquery=cb.createQuery(Object[].class);
Root<Car> root=cquery.from(User.class);
cquery.multiselect(root.get("id"),root.get("Name"));
Query<Object[]> q=session.createQuery(cquery);
List<Object[]> list=q.getResultList();
System.out.println("id Name");
for (Object[] objects : list) {
System.out.println(objects[0]+" "+objects[1]);
}
This is supported by hibernate 5. createCriteria
is deprecated in further version of hibernate. So you can use criteria builder
instead.
I found this really nifty open source ECMAScript compliant JS Engine completely written in C called duktape
Duktape is an embeddable Javascript engine, with a focus on portability and compact footprint.
Good luck!
You can just use:
> names(LIST)
[1] "A" "B"
Obviously the names of the first element is just
> names(LIST)[1]
[1] "A"
You only have to replace the WHERE with a LEFT JOIN:
SELECT CASE
WHEN S.Id IS NOT NULL AND S.Status = 1 AND ...) THEN 1
ELSE 0
END AS [Value]
FROM (SELECT @SiteId AS Id) R
LEFT JOIN Sites S ON S.Id = R.Id
This solution allows you to return default values for each column also, for example:
SELECT
CASE WHEN S.Id IS NULL THEN 0 ELSE S.Col1 END AS Col1,
S.Col2,
ISNULL(S.Col3, 0) AS Col3
FROM
(SELECT @Id AS Id) R
LEFT JOIN Sites S ON S.Id = R.Id AND S.Status = 1 AND ...
using (SqlConnection conn = new SqlConnection())
using (SqlCommand cmd = conn.CreateCommand())
{
cmd.CommandText = "INSERT INTO <table> (<date_column>) VALUES ('2010-01-01 12:00')";
cmd.ExecuteNonQuery();
}
It's been awhile since I wrote this stuff, so this may not be perfect. but the general idea is there.
WARNING: this is unsanitized. You should use parameters to avoid injection attacks.
EDIT: Since Jon insists.
On one of my sites I had to make a custom search by a lot of data some of it from custom fields here is how my $args look like for one of the options:
$args = array(
'meta_query' => $meta_query,
'tax_query' => array(
$query_tax
),
'posts_per_page' => 10,
'post_type' => 'ad_listing',
'orderby' => $orderby,
'order' => $order,
'paged' => $paged
);
where "$meta_query" is:
$key = "your_custom_key"; //custom_color for example
$value = "blue";//or red or any color
$query_color = array('key' => $key, 'value' => $value);
$meta_query[] = $query_color;
and after that:
query_posts($args);
so you would probably get more info here: http://codex.wordpress.org/Class_Reference/WP_Query and you can search for "meta_query" in the page to get to the info
Actually you can also make the Junit test a runnable Jar and call the runnable jar as java -jar
The problem is that your regex is a string, but html
is bytes:
>>> type(html)
<class 'bytes'>
Since python doesn't know how those bytes are encoded, it throws an exception when you try to use a string regex on them.
You can either decode
the bytes to a string:
html = html.decode('ISO-8859-1') # encoding may vary!
title = re.findall(pattern, html) # no more error
Or use a bytes regex:
regex = rb'<title>(,+?)</title>'
# ^
In this particular context, you can get the encoding from the response headers:
with urllib.request.urlopen(url) as response:
encoding = response.info().get_param('charset', 'utf8')
html = response.read().decode(encoding)
See the urlopen
documentation for more details.
See django docs for views.login(), you supply a 'next' value (as a hidden field) on the input form to redirect to after a successful login.
Put them into a list
and use merge
with Reduce
Reduce(function(x, y) merge(x, y, all=TRUE), list(df1, df2, df3))
# id v1 v2 v3
# 1 1 1 NA NA
# 2 10 4 NA NA
# 3 2 3 4 NA
# 4 43 5 NA NA
# 5 73 2 NA NA
# 6 23 NA 2 1
# 7 57 NA 3 NA
# 8 62 NA 5 2
# 9 7 NA 1 NA
# 10 96 NA 6 NA
You can also use this more concise version:
Reduce(function(...) merge(..., all=TRUE), list(df1, df2, df3))
Try using the onbeforeunload property, which will let the user choose whether he wants to navigate away from the page.
Example: https://developer.mozilla.org/en-US/docs/Web/API/Window.onbeforeunload
In HTML5 you can use sandbox property. Please see Pankrat's answer below. http://www.html5rocks.com/en/tutorials/security/sandboxed-iframes/
Browsing this comment section I came accross two different patterns answering the question. Sadly for SQL 2012, the second pattern doesn't work, so here's my "work around"
This is the easiest case you can encounter. Like many user pointed out, all you really need to do is add an Order By
at the end of the query
SELECT a FROM table1
UNION
SELECT a FROM table2
ORDER BY field1
or
SELECT a FROM table1 ORDER BY field1
UNION
SELECT a FROM table2 ORDER BY field1
Here's where it actually gets tricky. Using SQL 2012, I tried the top post and it doesn't work.
SELECT * FROM
(
SELECT table1.field1 FROM table1 ORDER BY table1.field1
) DUMMY_ALIAS1
UNION ALL
SELECT * FROM
(
SELECT table2.field1 FROM table2 ORDER BY table2.field1
) DUMMY_ALIAS2
Following the recommandation in the comment I tried this
SELECT * FROM
(
SELECT TOP 100 PERCENT table1.field1 FROM table1 ORDER BY table1.field1
) DUMMY_ALIAS1
UNION ALL
SELECT * FROM
(
SELECT TOP 100 PERCENT table2.field1 FROM table2 ORDER BY table2.field1
) DUMMY_ALIAS2
This code did compile but the DUMMY_ALIAS1
and DUMMY_ALIAS2
override the Order By
established in the Select
statement which makes this unusable.
The only solution that I could think of, that worked for me was not using a union and instead making the queries run individually and then dealing with them. So basically, not using a Union
when you want to Order By
Concerning the folders you mentioned:
/libs
is usually used for custom classes/functions/modules
/vendor
or /support
contains 3rd party libraries (added as git
sub-module when using git as source control)/spec
contains specifications for BDD tests./tests
contains the unit-tests for an application (using a testing
framework, see
here)NOTE: both /vendor
and /support
are deprecated since NPM introduced a clean package management. It's recommended to handle all 3rd-party dependencies using NPM and a package.json file
When building a rather large application, I recommend the following additional folders (especially if you are using some kind of MVC- / ORM-Framework like express or mongoose):
/models
contains all your ORM models (called Schemas
in mongoose)/views
contains your view-templates (using any templating language supported in express)/public
contains all static content (images, style-sheets, client-side JavaScript)
/assets/images
contains image files/assets/pdf
contains static pdf files/css
contains style sheets (or compiled output by a css engine)/js
contains client side JavaScript/controllers
contain all your express routes, separated by module/area of your application (note: when using the bootstrapping functionality of express, this folder is called /routes
)I got used to organize my projects this way and i think it works out pretty well.
Update for CoffeeScript-based Express applications (using connect-assets):
/app
contains your compiled JavaScript/assets/
contains all client-side assets that require compilation
/assets/js
contains your client-side CoffeeScript files/assets/css
contains all your LESS/Stylus style-sheets/public/(js|css|img)
contains your static files that are not handled by any compilers/src
contains all your server-side specific CoffeeScript files/test
contains all unit testing scripts (implemented using a testing-framework of your choice)/views
contains all your express views (be it jade, ejs or any other templating engine)Distributed (a)synchronous computing.
A real world example could be an application-wide notification framework, which sends mails to the stakeholders at various points during the course of application usage. So the application would act as a Producer
by create a Message
object, putting it on a particular Queue
, and moving forward.
There would be a set of Consumer
s who would subscribe to the Queue
in question, and would take care handling the Message
sent across. Note that during the course of this transaction, the Producer
s are decoupled from the logic of how a given Message
would be handled.
Messaging frameworks (ActiveMQ and the likes) act as a backbone to facilitate such Message
transactions by providing MessageBroker
s.
System.out.println(Name + " " + Income);
Is that what you mean? That will put a space between the name and the income?
You can also use position fixed css property.
<!-- html code -->
<div class="box" id="myElement"></div>

I'm a little confused about custom made completion handlers. In your example:
Say you have a download function to download a file from network,and want to be notified when download task has finished.
typealias CompletionHandler = (success:Bool) -> Void
func downloadFileFromURL(url: NSURL,completionHandler: CompletionHandler) {
// download code.
let flag = true // true if download succeed,false otherwise
completionHandler(success: flag)
}
Your // download code
will still be ran asynchronously. Why wouldn't the code go straight to your let flag = true
and completion Handler(success: flag)
without waiting for your download code to be finished?
Following one is working fine with moments js 2.10 and above
$.fn.dataTableExt.afnFiltering.push(
function( settings, data, dataIndex ) {
var min = $('#min-date').val()
var max = $('#max-date').val()
var createdAt = data[0] || 0; // Our date column in the table
//createdAt=createdAt.split(" ");
var startDate = moment(min, "DD/MM/YYYY");
var endDate = moment(max, "DD/MM/YYYY");
var diffDate = moment(createdAt, "DD/MM/YYYY");
//console.log(startDate);
if (
(min == "" || max == "") ||
(diffDate.isBetween(startDate, endDate))
) { return true; }
return false;
}
);
You can also do this with hooks.
function MyComponent (props) {
const [isActive, setActive] = useState(false);
const toggleClass = () => {
setActive(!isActive);
};
return (
<div
className={isActive ? 'your_className': null}
onClick={toggleClass}
>
<p>{props.text}</p>
</div>
);
}
xCode just copy all crashes logs. If you want to speed-up: delete number of crash reports after you analyze it, directly in this window.

1) I added libxml file to the Build Phases.follow this link
2) I added Other Linker Flags as -ObjC
(For both project and test project targets)
3) I setup Header Search Path as "${SDKROOT}/usr/include/libxml2"
(Don't forget double quote in either side) (For both project and test project targets)
One of them will solve the issue. If not you have to apply all three of the above.
Just put your data into an Object like this:
var myObject = new Object();
myObject.name = "John";
myObject.age = 12;
myObject.pets = ["cat", "dog"];
Afterwards stringify it via:
var myString = JSON.stringify(myObject);
You don't need jQuery for this. It's pure JS.
Your problem may have been due to a deficiency in an earlier version of Swift or of the Xcode Beta. Working with Xcode Version 6.0 (6A279r) on August 21, 2014, your code works as expected with this output:
column: 0 row: 0 value:1.0 column: 0 row: 1 value:4.0 column: 0 row: 2 value:7.0 column: 1 row: 0 value:2.0 column: 1 row: 1 value:5.0 column: 1 row: 2 value:8.0 column: 2 row: 0 value:3.0 column: 2 row: 1 value:6.0 column: 2 row: 2 value:9.0
I just copied and pasted your code into a Swift playground and defined two constants:
let NumColumns = 3, NumRows = 3
Set up a trap (you can trap several signals with one handler):
signal (SIGQUIT, my_handler); signal (SIGINT, my_handler);
Handle the signal however you want, but be aware of limitations and gotchas:
void my_handler (int sig) { /* Your code here. */ }
To access a variable in a class, you must use $this->myVar
instead of $this->$myvar
.
And, you should use access identifier to declare a variable instead of var
.
Please read the doc here.
As I learned, no one of those several solutions are perfects. Using a favicon generator is indeed a good solution but their number is overwhelming and it's hard to choose. I d'like to add that if you want your website to be PWA enabled, you need to provide also a 512x512 icon as stated by Google Devs :
icons including a 192px and a 512px version
I didn't met a lot of favicon generators enforcing that criteria (firebase does, but there is a lot of things it doesn't do). So the solution must be a mix of many other solutions.
I don't know, today at the begining of 2020 if providing a 16x16, 32x32 still relevant. I guess it still matters in certain context like, for example, if your users still use IE for some reason (this stills happen in some privates companies which doesn't migrate to a newer browser for some reasons)
Here is what worked in my case. Might be less performance intensive.
$('#myelement').siblings('input').first().focus();
There's actually a good reason:
The non-static access does not always work, for reasons of ambiguity.
Suppose we have two classes, A and B, the latter being a subclass of A, with static fields with the same name:
public class A {
public static String VALUE = "Aaa";
}
public class B extends A {
public static String VALUE = "Bbb";
}
Direct access to the static variable:
A.VALUE (="Aaa")
B.VALUE (="Bbb")
Indirect access using an instance (gives a compiler warning that VALUE should be statically accessed):
new B().VALUE (="Bbb")
So far, so good, the compiler can guess which static variable to use, the one on the superclass is somehow farther away, seems somehow logical.
Now to the point where it gets tricky: Interfaces can also have static variables.
public interface C {
public static String VALUE = "Ccc";
}
public interface D {
public static String VALUE = "Ddd";
}
Let's remove the static variable from B, and observe following situations:
B implements C, D
B extends A implements C
B extends A implements C, D
B extends A implements C
where A implements D
B extends A implements C
where C extends D
The statement new B().VALUE
is now ambiguous, as the compiler cannot decide which static variable was meant, and will report it as an error:
error: reference to VALUE is ambiguous
both variable VALUE in C and variable VALUE in D match
And that's exactly the reason why static variables should be accessed in a static way.
var singleClickTimer = 0; //define a var to hold timer event in parent scope
jqueryElem.click(function(e){ //using jquery click handler
if (e.detail == 1) { //ensure this is the first click
singleClickTimer = setTimeout(function(){ //create a timer
alert('single'); //run your single click code
},250); //250 or 1/4th second is about right
}
});
jqueryElem.dblclick(function(e){ //using jquery dblclick handler
clearTimeout(singleClickTimer); //cancel the single click
alert('double'); //run your double click code
});
Hey I also got the same problem on my server. I just changed the following things :
change php.ini
to...
memory_limit = 128M
and add to httpd.conf
RLimitMEM 1073741824 2147483648
and restart apache & i removed the error :
There are several way to do it, may decide to go the native way by downloading a VM application for linux and the install Mac OS in your VM and then download the Xcode application for mac But the true is i tried this path but it was really long so i decide to get sencha touch and phonegap for mobile phone,here the sencha-touch is a javascript framework that will help you in developing the interfaces and the phonegap is also javascript library which will help to access the feature of your Iphone or any oher mobile platform I'm using sencha-touch and phonegap ,its really work for me
You shouldn't use strcpy()
to copy a std::string
, only use it for C-Style strings.
If you want to copy a
to b
then just use the =
operator.
string a = "text";
string b = "image";
b = a;
I actually got this error because I was checking InnerHtml for some content that was generated dynamically - i.e. a control that is runat=server.
To solve this I had to remove the "static" keyword on my method, and it ran fine.
I see a lot of REST APIs that don't handle parameters well. One example that comes up often is when the URI includes personally identifiable information.
http://software.danielwatrous.com/design-principles-for-rest-apis/
I think a corollary question is when a parameter shouldn't be a parameter at all, but should instead be moved to the HEADER or BODY of the request.
I realize this question is over a year old, but I just stumbled across it in dealing with a similar problem and thought I would share another potential solution in case it might help a future traveler (or myself, when I forget this later and find myself flopping around on StackOverflow between screams and throwings of the nearest object on my desk).
In my case I was able to get the effect I wanted by using a DataGridTemplateColumn instead of a DataGridComboBoxColumn, a la the following snippet. [caveat: I'm using .NET 4.0, and what I've been reading leads me to believe the DataGrid has done a lot of evolving, so YMMV if using earlier version]
<DataGridTemplateColumn Header="Identifier_TEMPLATED">
<DataGridTemplateColumn.CellEditingTemplate>
<DataTemplate>
<ComboBox IsEditable="False"
Text="{Binding ComponentIdentifier,Mode=TwoWay,UpdateSourceTrigger=PropertyChanged}"
ItemsSource="{Binding Path=ApplicableIdentifiers, Mode=OneWay, UpdateSourceTrigger=PropertyChanged}" />
</DataTemplate>
</DataGridTemplateColumn.CellEditingTemplate>
<DataGridTemplateColumn.CellTemplate>
<DataTemplate>
<TextBlock Text="{Binding ComponentIdentifier}" />
</DataTemplate>
</DataGridTemplateColumn.CellTemplate>
</DataGridTemplateColumn>
var dataSource = lst!=null && lst.Any() ? lst : null;

Just in case someone comes here trying to know how to create a tuple assigning each part of the string "Quattro" and "TT" to an element of the list, it would be like this

I noticed that all the answers here use inline onClick
handlers. It's generally recommended to keep HTML and Javascript separate.
Here's an answer that adds a click event listener directly to the button. When it's clicked, it calls location.reload which causes the page to reload with the current URL.
const refreshButton = document.querySelector('.refresh-button');_x000D_
_x000D_
const refreshPage = () => {_x000D_
location.reload();_x000D_
}_x000D_

Never try to edit to @_ variable!!!! They must be not touched.. Or you get some unsuspected effect. For example...
my $size=1234;
sub sub1{
$_[0]=500;
}
sub1 $size;
Before call sub1 $size contain 1234. But after 500(!!) So you Don't edit this value!!! You may pass two or more values and change them in subroutine and all of them will be changed! I've never seen this effect described. Programs I've seen also leave @_ array readonly. And only that you may safely pass variable don't changed internal subroutine You must always do that:
sub sub2{
my @m=@_;
....
}
assign @_ to local subroutine procedure variables and next worked with them. Also in some deep recursive algorithms that returun array you may use this approach to reduce memory used for local vars. Only if return @_ array the same.

In this answer I copy Dennis Williamson's answer and modify it slightly to allow a vast speed increase when piping a column of many timestamps to the script. For example, piping 1000 timestamps to the original script with xargs -n1 on my machine took 6.929s as opposed to 0.027s with this modified version:
#!/bin/bash
LANG=C
if [[ -z "$1" ]]
then
if [[ -p /dev/stdin ]] # input from a pipe
then
cat - | gawk '{ print strftime("%c", $1); }'
else
echo "No timestamp given." >&2
exit
fi
else
date -d @$1 +%c
fi
input type="submit"
is the best way to have a submit button in a form. The downside of this is that you cannot put anything other than text as its value. The button element can contain other HTML elements and content.
Try putting type="submit"
instead of type="button"
in your button
element (source).
Pay particular attention however to the following from that page:
If you use the button element in an HTML form, different browsers will submit different values. Internet Explorer will submit the text between the
<button>
and</button>
tags, while other browsers will submit the content of the value attribute. Use the input element to create buttons in an HTML form.
I faced the same 415
http error when sending objects, serialized into JSON, via PUT/PUSH requests to my JAX-rs services, in other words my server was not able to de-serialize the objects from JSON.
In my case, the server was able to serialize successfully the same objects in JSON when sending them into its responses.
As mentioned in the other responses I have correctly set the Accept
and Content-Type
headers to application/json
, but it doesn't suffice.
Solution
I simply forgot a default constructor with no parameters for my DTO objects. Yes this is the same reasoning behind @Entity objects, you need a constructor with no parameters for the ORM to instantiate objects and populate the fields later.
Adding the constructor with no parameters to my DTO objects solved my issue. Here follows an example that resembles my code:
Wrong
@XmlRootElement
@XmlAccessorType(XmlAccessType.FIELD)
public class NumberDTO {
public NumberDTO(Number number) {
this.number = number;
}
private Number number;
public Number getNumber() {
return number;
}
public void setNumber(Number string) {
this.number = string;
}
}
Right
@XmlRootElement
@XmlAccessorType(XmlAccessType.FIELD)
public class NumberDTO {
public NumberDTO() {
}
public NumberDTO(Number number) {
this.number = number;
}
private Number number;
public Number getNumber() {
return number;
}
public void setNumber(Number string) {
this.number = string;
}
}
I lost hours, I hope this'll save yours ;-)
Here is how it works for me with no Servlet use.
Let's say I am trying to access web.xml in project/WebContent/WEB-INF/web.xml
In project property Source-tab add source folder by pointing to the parent container for WEB-INF folder (in my case WebContent )
Now let's use class loader:
InputStream inStream = class.getClass().getClassLoader().getResourceAsStream("Web-INF/web.xml")
It's as simple as return false;
ex.
jQuery("li a:eq(0)").click(function(){
return false;
})
or
jQuery("#menu a").click(function(){
return false;
})
As csgillespie said. stringsAsFactors is default on TRUE, which converts any text to a factor. So even after deleting the text, you still have a factor in your dataframe.
Now regarding the conversion, there's a more optimal way to do so. So I put it here as a reference :
> x <- factor(sample(4:8,10,replace=T))
> x
[1] 6 4 8 6 7 6 8 5 8 4
Levels: 4 5 6 7 8
> as.numeric(levels(x))[x]
[1] 6 4 8 6 7 6 8 5 8 4
To show it works.
The timings :
> x <- factor(sample(4:8,500000,replace=T))
> system.time(as.numeric(as.character(x)))
user system elapsed
0.11 0.00 0.11
> system.time(as.numeric(levels(x))[x])
user system elapsed
0 0 0
It's a big improvement, but not always a bottleneck. It gets important however if you have a big dataframe and a lot of columns to convert.
SOAPAction is required in SOAP 1.1 but can be empty ("").
See https://www.w3.org/TR/2000/NOTE-SOAP-20000508/#_Toc478383528
"The header field value of empty string ("") means that the intent of the SOAP message is provided by the HTTP Request-URI."
Try setting SOAPAction=""
On Xcode 8
the methods are converted to properties, so the following works with Swift
:
override public var supportedInterfaceOrientations: UIInterfaceOrientationMask {
return UIInterfaceOrientationMask.portrait
}
override public var preferredInterfaceOrientationForPresentation: UIInterfaceOrientation {
return UIInterfaceOrientation.portrait
}
override public var shouldAutorotate: Bool {
return true
}
Another alternative is to nest conditions
<ng-container *ngIf="foo === 1;else second"></ng-container>
<ng-template #second>
<ng-container *ngIf="foo === 2;else third"></ng-container>
</ng-template>
<ng-template #third></ng-template>
fname = "feed.txt"
feed = open(fname, 'r')
num_lines = len(feed.splitlines())
num_words = 0
num_chars = 0
for line in lines:
num_words += len(line.split())
And in case you come here, like I did, looking to do the same thing for plots in a Julia notebook in Jupyter, using Plots, you can use:
IJulia.clear_output(true)
so for a kind of animated plot of multiple runs
if nrun==1
display(plot(x,y)) # first plot
else
IJulia.clear_output(true) # clear the window (as above)
display(plot!(x,y)) # plot! overlays the plot
end
Without the clear_output call, all plots appear separately.
There is NNCron for Windows. IT can schedule jobs to be run periodically.
As other answers have pointed, on UNIX systems the numbers represent CPU load averages over 1/5/15 minute periods. But on Linux (and consequently Android), what it represents is something different.
After a kernel patch dating back to 1993 (a great in-depth article on the subject), in Linux the load average numbers no longer strictly represent the CPU load: as the calculation accounts not only for CPU bound processes, but also for processes in uninterruptible wait state - the original goal was to account for I/O bound processes this way, to represent more of a "system load" than just CPU load. The issue is that since 1993 the usage of uninterruptible state has grown in Linux kernel, and it no longer typically represents an I/O bound process. The problem is further exacerbated by some Linux devs using uninterruptible waits as an easy wait to avoid accommodating signals in their implementations. As a result, in Linux (and Android) we can see skewed high load average numbers that do not objectively represent the real load. There are Android user reports about unreasonable high load averages contrasting low CPU utilization. For example, my old Android phone (with 2 CPU cores) normally shown average load of ~12 even when the system and CPUs were idle. Hence, average load numbers in Linux (Android) does not turn out to be a reliable performance metric.
the plus works just fine, i personally prefer using the concat function.
var s = string.Concat(string 1, string 2, string, 3, etc)
Float won't convert into NVARCHAR directly, first we need to convert float into money datatype and then convert into NVARCHAR, see the examples below.
SELECT CAST(CAST(1234567890.1234 AS FLOAT) AS NVARCHAR(100))
output
1.23457e+009
SELECT CAST(CAST(CAST(1234567890.1234 AS FLOAT) AS MONEY) AS NVARCHAR(100))
output
1234567890.12
In Example2 value is converted into float to NVARCHAR
For MySql:
GROUP BY
DATE(`your_date_field`),
HOUR(`your_date_field`),
FLOOR( MINUTE(`your_date_field`) / 10);
See answer from Gary Makin. And you need change the format or data. Because the data that you have do not fit under the chosen format. For example this code works correct:
let dateFormatter = NSDateFormatter()
dateFormatter.dateFormat = "MM-dd-yyyy"
let dateObj = dateFormatter.dateFromString("10 10 2001")
print("Dateobj: \(dateObj)")
For people who find this via search engines, you do not need VBA. You can just:
1.) select the query or table with your mouse
2.) click export data from the ribbon
3.) click excel from the export subgroup
4.) follow the wizard to select the output file and location.
personally i'd suggest (for readability):
$('<div>');
some numbers on the suggestions so far (safari 3.2.1 / mac os x):
var it = 50000;
var start = new Date().getTime();
for (i = 0; i < it; ++i) {
// test creation of an element
// see below statements
}
var end = new Date().getTime();
alert( end - start );
var e = $( document.createElement('div') ); // ~300ms
var e = $('<div>'); // ~3100ms
var e = $('<div></div>'); // ~3200ms
var e = $('<div/>'); // ~3500ms

You need to give a function to be called after the time delay as the second argument to after
:
after(delay_ms, callback=None, *args)
Registers an alarm callback that is called after a given time.
So what you really want to do is this:
tiles_letter = ['a', 'b', 'c', 'd', 'e']
def add_letter():
rand = random.choice(tiles_letter)
tile_frame = Label(frame, text=rand)
tile_frame.pack()
root.after(500, add_letter)
tiles_letter.remove(rand) # remove that tile from list of tiles
root.after(0, add_letter) # add_letter will run as soon as the mainloop starts.
root.mainloop()
You also need to schedule the function to be called again by repeating the call to after
inside the callback function, since after
only executes the given function once. This is also noted in the documentation:
The callback is only called once for each call to this method. To keep calling the callback, you need to reregister the callback inside itself
Note that your example will throw an exception as soon as you've exhausted all the entries in tiles_letter
, so you need to change your logic to handle that case whichever way you want. The simplest thing would be to add a check at the beginning of add_letter
to make sure the list isn't empty, and just return
if it is:
def add_letter():
if not tiles_letter:
return
rand = random.choice(tiles_letter)
tile_frame = Label(frame, text=rand)
tile_frame.pack()
root.after(500, add_letter)
tiles_letter.remove(rand) # remove that tile from list of tiles
Live-Demo: repl.it
That's the correct usage, but perhaps the spaces in the path name are messing things up for some reason.
You may want to run the program under cmd.exe as well so you can see any output from flow.exe that might be indicating an error.
This is discouraged (if you want to create/distribute a clean Docker image), since the PATH
variable is set by /etc/profile
script, the value can be overridden.
head /etc/profile
:
if [ "`id -u`" -eq 0 ]; then
PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin"
else
PATH="/usr/local/bin:/usr/bin:/bin:/usr/local/games:/usr/games"
fi
export PATH
At the end of the Dockerfile, you could add:
RUN echo "export PATH=$PATH" > /etc/environment
So PATH is set for all users.
Ok, Yet another ugly solution:
Create a function in Papa like:
protected function call2Granpa() {
return parent::__construct();
}
Then in Kiddo you use:
parent::call2Granpa();
//instead of calling constructor in Papa.
I think it could work... I haven't test it, so I'm not sure if the objects are created correctly.
I used this approach but with non-constructor functions.
To chime in with another solution - I found that the "listen for bounds_changed event and then set new zoom" approach didn't work reliably for me. I think that I was sometimes calling fitBounds
before the map had been fully initialized, and the initialization was causing a bounds_changed event that would use up the listener, before fitBounds
changed the boundaries and zoom level. I ended up with this code, which seems to work so far:
// If there's only one marker, or if the markers are all super close together,
// `fitBounds` can zoom in too far. We want to limit the maximum zoom it can
// use.
//
// `fitBounds` is asynchronous, so we need to wait until the bounds have
// changed before we know what the new zoom is, using an event handler.
//
// Sometimes this handler gets triggered by a different event, before
// `fitBounds` takes effect; that particularly seems to happen if the map
// hasn't been fully initialized yet. So we don't immediately remove the
// listener; instead, we wait until the 'idle' event, and remove it then.
//
// But 'idle' might happen before 'bounds_changed', so we can't set up the
// removal handler immediately. Set it up in the first event handler.
var removeListener = null;
var listener = google.maps.event.addListener(map, 'bounds_changed', () => {
console.log(map.getZoom());
if (map.getZoom() > 15) {
map.setZoom(15);
}
if (!removeListener) {
removeListener = google.maps.event.addListenerOnce(map, 'idle', () => {
console.log('remove');
google.maps.event.removeListener(listener);
});
}
});
You can also capitalize the first letter of the match using \I1
and \I2
etc instead of $1
and $2
.
An example of how to implement it:
public bool ValidateSocialSecNumber(string socialSecNumber)
{
//Accepts only 10 digits, no more no less. (Like Mike's answer)
Regex pattern = new Regex(@"(?<!\d)\d{10}(?!\d)");
if(pattern.isMatch(socialSecNumber))
{
//Do something
return true;
}
else
{
return false;
}
}
You could've also done it in another way by e.g. using Match
and then wrapping a try-catch block around the pattern matching. However, if a wrong input is given quite often, it's quite expensive to throw an exception. Thus, I prefer the above way, in simple cases at least.
Most used way is, anonymous declaration
Button send = (Button) findViewById(R.id.buttonSend);
send.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// handle click
}
});
Also you can create View.OnClickListener object and set it to button later, but you still need to override onClick method for example
View.OnClickListener listener = new View.OnClickListener(){
@Override
public void onClick(View v) {
// handle click
}
}
Button send = (Button) findViewById(R.id.buttonSend);
send.setOnClickListener(listener);
When your activity implements OnClickListener interface you must override onClick(View v) method on activity level. Then you can assing this activity as listener to button, because it already implements interface and overrides the onClick() method
public class MyActivity extends Activity implements View.OnClickListener{
@Override
public void onClick(View v) {
// handle click
}
@Override
public void onCreate(Bundle b) {
Button send = (Button) findViewById(R.id.buttonSend);
send.setOnClickListener(this);
}

(imho) 4-th approach used when multiple buttons have same handler, and you can declare one method in activity class and assign this method to multiple buttons in xml layout, also you can create one method for one button, but in this case I prefer to declare handlers inside activity class.
As inspiredlife explained, you can figure out whats happening using mail
command.
If you don't want to delete bunch of unrelated / auto-generated messages one by one (like me), simply run the command below to get rid of all messages:
echo -n > /var/mail/yourusername
I'm not sure about g++, but if you're using GNU Make then "make -j N" (where N is the number of threads make can create) will allow make to run multple g++ jobs at the same time (so long as the files do not depend on each other).
The recommended way is to create your own component, such as MyAppText. MyAppText would be a simple component that renders a Text component using your universal style and can pass through other props, etc.

You can reach your goals too without jQuery with normal JavaScript.
Now the newBtn is linkes with the html_btn and you can style your new btn like you want :D
Changing the datatype to varbinary seems to work the best for me.

Dim WS as Worksheet
Set WS = Sheets.Add
You don't have to know where it's located, or what it's name is, you just refer to it as WS.
If you still want to do this the "old fashioned" way, try this:
Sheets.Add.Name = "Test"
I had the same issue, testing a bunch of different examples, and tried all the possible solutions. What finally got it working for me was when I added a @Path("")
over the class line, I had left that out.
This can be achieved by using constructor function instead of literal
var o = new function() {
this.foo = "it";
this.bar = this.foo + " works"
}
alert(o.bar)
Keep the breaks - you're less likely to run into trouble if/when you edit the code later if the breaks are already in place.
Having said that, it's considered by many (including me) to be bad practice to return from the middle of a function. Ideally a function should have one entry point and one exit point.
To start all the containers:
docker restart $(docker ps -a -q)
Use sudo if you don't have permission to perform this:
sudo docker restart $(sudo docker ps -a -q)

You just need to add an "A" record in the DNS manager on Godaddy. In that "A" record put your IP from dreamhost.
I know this works since I'm doing the very same thing.

's answer below; this feature now exists in C#
var @switch = new Dictionary<Type, Action> {
{ typeof(Type1), () => ... },
{ typeof(Type2), () => ... },
{ typeof(Type3), () => ... },
};
@switch[typeof(MyType)]();
It's a little less flexible as you can't fall through cases, continue etc. But I rarely do so anyway.
Here is a more generalized solution that prints all elements of x the vector x in this format:
x=randperm(3);
s = repmat('%d,',1,length(x));
s(end)=[]; %Remove trailing comma
disp(sprintf(['Answer: (' s ')'], x))
$(document).ready(function() {
$('#Button').click(function() {
$(this).addClass('active');
});
});
should do the trick. unless you're loading the button with ajax. In which case you could do:
$('#Button').live('click', function() {...
Also remember not to use the same id more than once in your html code.

Does not matter for inner joins
Matters for outer joins
a. WHERE
clause: After joining. Records will be filtered after join has taken place.
b. ON
clause - Before joining. Records (from right table) will be filtered before joining. This may end up as null in the result (since OUTER join).
Example: Consider the below tables:
1. documents:
| id | name |
--------|-------------|
| 1 | Document1 |
| 2 | Document2 |
| 3 | Document3 |
| 4 | Document4 |
| 5 | Document5 |
2. downloads:
| id | document_id | username |
|------|---------------|----------|
| 1 | 1 | sandeep |
| 2 | 1 | simi |
| 3 | 2 | sandeep |
| 4 | 2 | reya |
| 5 | 3 | simi |
a) Inside WHERE
clause:
SELECT documents.name, downloads.id
FROM documents
LEFT OUTER JOIN downloads
ON documents.id = downloads.document_id
WHERE username = 'sandeep'
For above query the intermediate join table will look like this.
| id(from documents) | name | id (from downloads) | document_id | username |
|--------------------|--------------|---------------------|-------------|----------|
| 1 | Document1 | 1 | 1 | sandeep |
| 1 | Document1 | 2 | 1 | simi |
| 2 | Document2 | 3 | 2 | sandeep |
| 2 | Document2 | 4 | 2 | reya |
| 3 | Document3 | 5 | 3 | simi |
| 4 | Document4 | NULL | NULL | NULL |
| 5 | Document5 | NULL | NULL | NULL |
After applying the `WHERE` clause and selecting the listed attributes, the result will be:
| name | id |
|--------------|----|
| Document1 | 1 |
| Document2 | 3 |
b) Inside JOIN
clause
SELECT documents.name, downloads.id
FROM documents
LEFT OUTER JOIN downloads
ON documents.id = downloads.document_id
AND username = 'sandeep'
For above query the intermediate join table will look like this.
| id(from documents) | name | id (from downloads) | document_id | username |
|--------------------|--------------|---------------------|-------------|----------|
| 1 | Document1 | 1 | 1 | sandeep |
| 2 | Document2 | 3 | 2 | sandeep |
| 3 | Document3 | NULL | NULL | NULL |
| 4 | Document4 | NULL | NULL | NULL |
| 5 | Document5 | NULL | NULL | NULL |
Notice how the rows in `documents` that did not match both the conditions are populated with `NULL` values.
After Selecting the listed attributes, the result will be:
| name | id |
|------------|------|
| Document1 | 1 |
| Document2 | 3 |
| Document3 | NULL |
| Document4 | NULL |
| Document5 | NULL |
You can create your own custom auth schemas that use the Authorization:
header - for example, this is how OAuth works.
As a general rule, if servers or proxies don't understand the values of standard headers, they will leave them alone and ignore them. It is creating your own header keys that can often produce unexpected results - many proxies will strip headers with names they don't recognise.
Having said that, it is possibly a better idea to use cookies to transmit the token, rather than the Authorization:
header, for the simple reason that cookies were explicitly designed to carry custom values, whereas the specification for HTTP's built in auth methods does not really say either way - if you want to see exactly what it does say, have a look here.
The other point about this is that many HTTP client libraries have built-in support for Digest and Basic auth but may make life more difficult when trying to set a raw value in the header field, whereas they will all provide easy support for cookies and will allow more or less any value within them.
Spend some time to make it working for me.

I found good online regex testing tool. Covered my regex with tests:
They are signals that application developers use. The kernel shouldn't ever send these to a process. You can send them using kill(2)
or using the utility kill(1)
.
If you intend to use signals for synchronization you might want to check real-time signals (there's more of them, they are queued, their delivery order is guaranteed etc).
For modern Python versions (3.4+), Path(__file__).name
should be more idiomatic. Also, Path(__file__).stem
gives you the script name without the .py
extension.
It's really a matter of opinion. In your example, System.out.println(5)
would be slightly more efficient, as you only refer to the number once and never change it. As was said in a comment, int
is a primitive type and not a reference - thus it doesn't take up much space. However, you might want to set actual reference variables to null only if they are used in a very complicated method. All local reference variables are garbage collected when the method they are declared in returns.
In my use case, I wanted to asynchronously retrieve a url, and then follow that url to an external resource in a new window. A directive seemed overkill because I don't need reusability, so I simply did:
<button (click)="navigateToResource()">Navigate</button>
And in my component.ts
navigateToResource(): void {
this.service.getUrl((result: any) => window.open(result.url));
}
Routing to a link indirectly like this will likely trigger the browser's popup blocker.

This is the same answer that Aaron Bertrand provided but it wasn't placed in an answer.
the error can be due to one of several missing package. Below command will install several packages like g++, gcc, etc.

Do not use more than one style attribute. Just seperate styles in the style attribute with ;
It is a block of inline CSS, so think of this as you would do CSS in a separate stylesheet.
So in this case its:
style="height:100px;width:100px;"
You can use this for any CSS style, so if you wanted to change the colour of the text to white:
style="height:100px;width:100px;color:#ffffff"
and so on.
However, it is worth using inline CSS sparingly, as it can make code less manageable in future. Using an external stylesheet may be a better option for this. It depends really on your requirements. Inline CSS does make for quicker coding.

Unicode escapes only work in unicode strings, so this
a="\u2026"
is actually a string of 6 characters: '\', 'u', '2', '0', '2', '6'.
To make unicode out of this, use decode('unicode-escape')
:
a="\u2026"
print repr(a)
print repr(a.decode('unicode-escape'))
## '\\u2026'
## u'\u2026'

All of the answers above (apart from Martin Andersson's) create a new list without the desired items, rather than removing the items from the original list.
>>> import random, timeit
>>> a = list(range(5)) * 1000
>>> random.shuffle(a)
>>> b = a
>>> print(b is a)
True
>>> b = [x for x in b if x != 0]
>>> print(b is a)
False
>>> b.count(0)
0
>>> a.count(0)
1000
>>> b = a
>>> b = filter(lambda a: a != 2, x)
>>> print(b is a)
False
This can be important if you have other references to the list hanging around.
To modify the list in place, use a method like this
>>> def removeall_inplace(x, l):
... for _ in xrange(l.count(x)):
... l.remove(x)
...
>>> removeall_inplace(0, b)
>>> b is a
True
>>> a.count(0)
0
As far as speed is concerned, results on my laptop are (all on a 5000 entry list with 1000 entries removed)
So the .remove loop is about 100x slower........ Hmmm, maybe a different approach is needed. The fastest I've found is using the list comprehension, but then replace the contents of the original list.
>>> def removeall_replace(x, l):
.... t = [y for y in l if y != x]
.... del l[:]
.... l.extend(t)
Think about it as array of array.
If you do this str[x][y], then there is array of length x where each element in turn contains array of length y. In java its not necessary for second dimension to have same length. So for x=i you can have y=m and x=j you can have y=n
For this your declaration looks like
String[][] test = new String[4][]; test[0] = new String[3]; test[1] = new String[2];
etc..
$file = Get-Item -Path "c:/foo/foobar.txt"
$file.Name
Works with both relative an absolute paths
Check this link . You were missing .

Use DATEADD in your WHERE clause:
...
WHERE date < DATEADD(day, -30, GETDATE())
You can also use abbreviation d

Monkey is right, according to the link given by monkey
Basically it's a way to map a combined/minified file back to an unbuilt state. When you build for production, along with minifying and combining your JavaScript files, you generate a source map which holds information about your original files. When you query a certain line and column number in your generated JavaScript you can do a lookup in the source map which returns the original location.
I am not sure if it is angular's fault that no map files were generated. But you can turn off source map files by unchecking this option in chrome console setting
They are as they were. That one key is JUST DELETED
As is the norm in Python there are several ways to do this. In all examples assume: lst = [1, 2, 3, 4, 5]
for index, element in enumerate(lst):
# do the things that need doing here
This is also the safest option in my opinion because the chance of going into infinite recursion has been eliminated. Both the item and its index are held in variables and there is no need to write any further code to access the item.
for
)for index in range(len(lst)): # or xrange
# you will have to write extra code to get the element
while
)index = 0
while index < len(lst):
# you will have to write extra code to get the element
index += 1 # escape infinite recursion
As explained before, there are other ways to do this that have not been explained here and they may even apply more in other situations. e.g using itertools.chain
with for. It handles nested loops better than the other examples.
Each database's implementation but you can probably guess that they all solve common problems in more or less the same way. If you are using MSSQL have a look at the execution plan that is generated. You can do this by turning on the profiler and executions plans. This will give you a text version when you run the command.
I am not sure what version of MSSQL you are using but you can get a graphical one in SQL Server 2000 in the query analyzer. I am sure that this functionality is lurking some where in SQL Server Studio Manager in later versions.
Have a look at the exeuction plan. As far as possible avoid table scans unless of course your table is small in which case a table scan is faster than using an index. Read up on the different join operations that each different scenario produces.
`ALTER TABLE `table_name` CHANGE `column_name`
timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP
ON UPDATE CURRENT_TIMESTAMP
Can be used to update the timestamp on update.
You could use preg_split
instead of explode
and split on [ ]+
(one or more spaces). But I think in this case you could go with preg_match_all
and capturing:
preg_match_all('/[ ]php[ ]+\S+[ ]+(\S+)/', $input, $matches);
$result = $matches[1];
The pattern matches a space, php
, more spaces, a string of non-spaces (the path), more spaces, and then captures the next string of non-spaces. The first space is mostly to ensure that you don't match php
as part of a user name but really only as a command.
An alternative to capturing is the "keep" feature of PCRE. If you use \K
in the pattern, everything before it is discarded in the match:
preg_match_all('/[ ]php[ ]+\S+[ ]+\K\S+/', $input, $matches);
$result = $matches[0];
I would use preg_match()
. I do something similar for many of my system management scripts. Here is an example:
$test = "user 12052 0.2 0.1 137184 13056 ? Ss 10:00 0:00 php /home/user/public_html/utilities/runProcFile.php cust1 cron
user 12054 0.2 0.1 137184 13064 ? Ss 10:00 0:00 php /home/user/public_html/utilities/runProcFile.php cust3 cron
user 12055 0.6 0.1 137844 14220 ? Ss 10:00 0:00 php /home/user/public_html/utilities/runProcFile.php cust4 cron

user 12059 0.3 0.1 135112 13000 ? Ss 10:00 0:00 php /home/user/public_html/utilities/runProcFile.php cust16 cron

root 12070 0.0 0.0 103240 828 pts/1 R+ 10:00 0:00 grep utilities";
$lines = explode("\n", $test);
foreach($lines as $line){
if(preg_match("/.php[\s+](cust[\d]+)[\s+]cron/i", $line, $matches)){
print_r($matches);
}
}
The above prints:
Array
(
[0] => .php cust1 cron
[1] => cust1
)
Array
(
[0] => .php cust3 cron
[1] => cust3
)
Array
(
[0] => .php cust4 cron
[1] => cust4
)
Array
(
[0] => .php cust89 cron
[1] => cust89
)
Array
(
[0] => .php cust435 cron
[1] => cust435
)
Array
(
[0] => .php cust16 cron
[1] => cust16
)
You can set $test
to equal the output from exec. the values you are looking for would be in the if
statement under the foreach
. $matches[1]
will have the custx value.
The Python idiom for opening a file and reading it line-by-line is:
with open('filename') as f:
for line in f:
do_something(line)
The file will be automatically closed at the end of the above code (the with
construct takes care of that).
Finally, it is worth noting that line
will preserve the trailing newline. This can be easily removed using:
line = line.rstrip()
You need to make sure the frame is fully loaded the best way to do it is to use onload:
<iframe id="nesgt" src="" onload="custom()"></iframe>
function custom(){
document.getElementById("nesgt").contentWindow.document;
}
this function will run automatically when the iframe is fully loaded.
it could be done with setTimeout but we can't get the exact time of the frame load.
hope this helps someone.
The problem with all methods indicated here is that you can't be sure that a method doesn't exist.
In Python you can intercept the dot calling through __getattr__
and __getattribute__
, making it possible to create method "at runtime"
Example:
class MoreMethod(object):
def some_method(self, x):
return x
def __getattr__(self, *args):
return lambda x: x*2
If you execute it, you can call non-existing methods in the object dictionary...
>>> o = MoreMethod()
>>> o.some_method(5)
5
>>> dir(o)
['__class__', '__delattr__', '__dict__', '__doc__', '__format__', '__getattr__', '__getattribute__', '__hash__', '__init__', '__module__', '__new__', '__reduce__', '__reduce_ex__', '__repr__', '__setattr__', '__sizeof__', '__str__', '__subclasshook__', '__weakref__', 'some_method']
>>> o.i_dont_care_of_the_name(5)
10
And it's why you use the Easier to ask for forgiveness than permission paradigms in Python.
In your 'test' directive Html tag, the attribute name of the function should not be camelCased, but dash-based.
so - instead of :
<test color1="color1" updateFn="updateFn()"></test>
write:
<test color1="color1" update-fn="updateFn()"></test>
This is angular's way to tell the difference between directive attributes (such as update-fn function) and functions.

Look into twitter cards.
The trick is not in the button but rather the page you are sharing. Twitter Cards pull the image from the meta tags similar to facebook
sharing.
Example:
<meta name="twitter:card" content="summary_large_image">
<meta name="twitter:site" content="@site_username">
<meta name="twitter:title" content="Top 10 Things Ever">
<meta name="twitter:description" content="Up than 200 characters.">
<meta name="twitter:creator" content="@creator_username">
<meta name="twitter:image" content="http://placekitten.com/250/250">
<meta name="twitter:domain" content="YourDomain.com">
You could add the time component
WHERE mydate<='2008-11-25 23:59:59'
but that might fail on DST switchover dates if mydate is '2008-11-25 24:59:59', so it's probably safest to grab everything before the next date:
WHERE mydate < '2008-11-26 00:00:00'

Simple way to do it in jQuery :
/* The elements we'll bind the shortcut keys to. */
var elements = "body, input, select, checkbox, textarea";
/* Bind the key short-cut 'Ctrl+S' to the save function. */
$(elements).bind ("keydown", "ctrl+space", function (e) {
// Prevent the default operation.
e.preventDefault ();
// Stop processing if we're already doing something.
console.log ("That's right , you pressed correct shortcut!");
});
Most methods for storing a dictionary use JSON, Pickle, or line reading. Providing you're not editing the dictionary outside of Python, this simple method should suffice for even complex dictionaries. Although Pickle will be better for larger dictionaries.
x = {1:'a', 2:'b', 3:'c'}
f = 'file.txt'
print(x, file=open(f,'w')) # file.txt >>> {1:'a', 2:'b', 3:'c'}
y = eval(open(f,'r').read())
print(x==y) # >>> True

In Java 8 and later, we have the java.time framework built into Java 8 and later. These new classes supplant the troublesome old java.util.Date/.Calendar classes. The new classes are inspired by the highly successful Joda-Time framework, intended as its successor, similar in concept but re-architected. Defined by JSR 310. Extended by the ThreeTen-Extra project. See the Tutorial.
Be aware that java.time is capable of nanosecond resolution (9 decimal places in fraction of second), versus the millisecond resolution (3 decimal places) of both java.util.Date & Joda-Time. So when formatting to display only 3 decimal places, you could be hiding data.
If you want to eliminate any microseconds or nanoseconds from your data, truncate.
Instant instant2 = instant.truncatedTo( ChronoUnit.MILLIS ) ;
The java.time classes use ISO 8601 format by default when parsing/generating strings. A Z
at the end is short for Zulu
, and means UTC.
An Instant
represents a moment on the timeline in UTC with resolution of up to nanoseconds. Capturing the current moment in Java 8 is limited to milliseconds, with a new implementation in Java 9 capturing up to nanoseconds depending on your computer’s hardware clock’s abilities.
Instant instant = Instant.now (); // Current date-time in UTC.
String output = instant.toString ();
2016-05-06T23:24:25.694Z
Replace the T
in the middle with a space, and the Z
with nothing, to get your desired output.
String output = instant.toString ().replace ( "T" , " " ).replace( "Z" , "" ; // Replace 'T', delete 'Z'. I recommend leaving the `Z` or any other such [offset-from-UTC][7] or [time zone][7] indicator to make the meaning clear, but your choice of course.
2016-05-06 23:24:25.694
As you don't care about including the offset or time zone, make a "local" date-time unrelated to any particular locality.
String output = LocalDateTime.now ( ).toString ().replace ( "T", " " );
The highly successful Joda-Time library was the inspiration for the java.time framework. Advisable to migrate to java.time when convenient.
The ISO 8601 format includes milliseconds, and is the default for the Joda-Time 2.4 library.
System.out.println( "Now: " + new DateTime ( DateTimeZone.UTC ) );
When run…
Now: 2013-11-26T20:25:12.014Z
Also, you can ask for the milliseconds fraction-of-a-second as a number, if needed:
int millisOfSecond = myDateTime.getMillisOfSecond ();
I was facing an issue where Slick carousel wasn't refreshing on new data, it was appending new slides to previous ones, I found an answer which solved my problem, it's very simple.
try unslick, then assign your new data which is being rendered inside slick carousel, and then initialize slick again. these were the steps for me:
jQuery('.class-or-#id').slick('unslick');
myData = my-new-data;
jQuery('.class-or-#id').slick({slick options});
Note: check slick website for syntax just in case. also make sure you are not using unslick before slick is even initialized, what that means is simply initialize (like this jquery('.my-class').slick({options}
); the first ajax call and once it is initialized then follow above steps, you may wanna use if else
as a quick fix to this question, make sure your compile Sdk verion, your buildtoolsversion, your appcompat, and finally your support library are all running on the same sdk version, for further clarity take a look at the image i just uploaded. Cheers. Follow the red annotations and get rid of that trouble.
you can try this too And it will work:
DECLARE
a NUMBER;
b NUMBER;
BEGIN
a :=: a; --this will take input from user
b :=: b;
DBMS_OUTPUT.PUT_LINE('a = '|| a);
DBMS_OUTPUT.PUT_LINE('b = '|| b);
END;
class User: Decodable {
var name: String
var email: String
var token: String
enum CodingKeys: String, CodingKey {
case name
case email
case token
}
public required init(from decoder: Decoder) throws {
let container = try decoder.container(keyedBy: CodingKeys.self)
self.name = try container.decode(String.self, forKey: .name)
self.email = try container.decode(String.self, forKey: .email)
self.token = try container.decode(String.self, forKey: .token)
}
}
Alamofire.request("url.endpoint/path", method: .get, parameters: params, encoding: URLEncoding.queryString, headers: nil)

let users = try JSONDecoder().decode([User].self, from: response.data!)

works

}, [props.items]);

The problem might be in the rest of the html, the part that you didn't post.
With this example (I just closed the open tags):
<a class="item" ng-href="#/catalog/90d9650a36988e5d0136988f03ab000f/category/DATABASE_SERVERS/service/90cefc7a42b3d4df0142b52466810026" href="#/catalog/90d9650a36988e5d0136988f03ab000f/category/DATABASE_SERVERS/service/90cefc7a42b3d4df0142b52466810026">
<div class="col-lg-2 col-sm-3 col-xs-4 item-list-image">
<img ng-src="csa/images/library/Service_Design.png" src="csa/images/library/Service_Design.png">
</div>
<div class="col-lg-8 col-sm-9 col-xs-8">
<div class="col-xs-12">
<p>
<strong class="ng-binding">Smoke Sequential</strong>
</p>
</div>
</div>
</a>
I was able to find the element without trouble with:
driver.findElement(By.linkText("Smoke Sequential")).click();
If there is more text inside the element, you could try a find by partial link text:
driver.findElement(By.partialLinkText("Sequential")).click();
Here is a function that takes in another function and outputs a version that runs async.
var async = function (func) {
return function () {
var args = arguments;
setTimeout(function () {
func.apply(this, args);
}, 0);
};
};
It is used as a simple way to make an async function:
var anyncFunction = async(function (callback) {
doSomething();
callback();
});
This is different from @fider's answer because the function itself has its own structure (no callback added on, it's already in the function) and also because it creates a new function that can be used.
imageToBase64 = (URL) => {
let image;
image = new Image();
image.crossOrigin = 'Anonymous';
image.addEventListener('load', function() {
let canvas = document.createElement('canvas');
let context = canvas.getContext('2d');
canvas.width = image.width;
canvas.height = image.height;
context.drawImage(image, 0, 0);
try {
localStorage.setItem('saved-image-example', canvas.toDataURL('image/png'));
} catch (err) {
console.error(err)
}
});
image.src = URL;
};
imageToBase64('image URL')
You can try using dictionary as:-
NSDictionary *infoDictionary = [[NSBundle mainBundle]infoDictionary];
NSString *buildVersion = infoDictionary[(NSString*)kCFBundleVersionKey];
NSString *bundleName = infoDictionary[(NSString *)kCFBundleNameKey]
Try:
s = filter(str.isalnum, s)
in Python3:
s = ''.join(filter(str.isalnum, s))
Edit: realized that the OP wants to replace non-chars with '*'. My answer does not fit
long add;
mem = (void*)malloc(1024 +15);
add = (long)mem;
add = add - (add % 16);//align to 16 byte boundary
ptr = (whatever*)(add);
I created a library that facilitates initial/demo data loading in a Spring Boot application. You can find it at https://github.com/piotrpolak/spring-boot-data-fixtures
Once the data fixtures starter is on the classpath, it will automatically try to load DICTIONARY
data upon application startup (this behavior can be controlled by properties) - all you need to do is to register a bean implementing DataFixture
.
I find loading initial data by code superior to loading it using SQL scripts:
Example data fixture:
/**
* You can have as many fixture classes as you want.
* @Order annotation is respected for the fixtures belonging to the same set.
* You can make your demo database to be incrementally updated with fresh data
* each time the application is redeployed - all you need to do is to write
* a good condition in `canBeLoaded()` method.
*/
@Component
public class InitialDataFixture implements DataFixture {
private final LanguageRepository languageRepository;
// ...
@Override
public DataFixtureSet getSet() {
return DataFixtureSet.DICTIONARY;
}
/**
* We want to make sure the fixture is applied once and once only.
* A more sophisticated condition can be used to create incremental demo data
* over time without the need to reset the QA database (for example).
*/
@Override
public boolean canBeLoaded() {
return languageRepository.size() == 0;
}
/**
* The actual application of the fixture.
* Assuming that data fixtures are registered as beans, this method can call
* other services and/or repositories.
*/
@Override
public void load() {
languageRepository.saveAll(Arrays.asList(
new Language("en-US"), new Language("pl-PL")));
}
}
The concept is inspired by the Symfony Doctrine Data Fixtures bundle.
Found this today, made a few tweaks and combined the features of the other answers while updating it to bootstrap 3.x. NB: This answer requires jQuery.
In html:
<div id="form_errors" class="alert alert-danger fade in" style="display:none">
In JS:
<script>
//http://stackoverflow.com/questions/10082330/dynamically-create-bootstrap-alerts-box-through-javascript
function bootstrap_alert(elem, message, timeout) {
$(elem).show().html('<div class="alert"><button type="button" class="close" data-dismiss="alert" aria-hidden="true">×</button><span>'+message+'</span></div>');
if (timeout || timeout === 0) {
setTimeout(function() {
$(elem).alert('close');
}, timeout);
}
};
</script>?
Then you can invoke this either as:
bootstrap_alert('#form_errors', 'This message will fade out in 1 second', 1000)
bootstrap_alert('#form_errors', 'User must dismiss this message manually')
Lots of answers available, speed is irrelevant for such small functions unless you are calling them a few hundred thousand times in a short period of time. For me, a regular expression is best, but keep it in a closure so you don't build it every time:
Simple version:
function vowelTest(s) {
return (/^[aeiou]$/i).test(s);
}
More efficient version:
var vowelTest = (function() {
var re = /^[aeiou]$/i;
return function(s) {
return re.test(s);
}
})();
Returns true
if s
is a single vowel (upper or lower case) and false
for everything else.
From Firefox 33 onwards you can call getBoundingClientRect() and it will work normally, i.e. in the question above it will return 300 x 100.
Firefox 33 will be released on 14th October 2014 but the fix is already in Firefox nightlies if you want to try it out.
You could also use Django Crispy Forms, it's a great tool to define forms in case you'd like to use some CSS framework like Bootstrap or Foundation. And it's easy to specify classes for your form fields there.
Your form class would like this then:
from django import forms
from crispy_forms.helper import FormHelper
from crispy_forms.layout import Layout, Div, Submit, Field
from crispy_forms.bootstrap import FormActions
class SampleClass(forms.Form):
name = forms.CharField(max_length=30)
age = forms.IntegerField()
django_hacker = forms.BooleanField(required=False)
helper = FormHelper()
helper.form_class = 'your-form-class'
helper.layout = Layout(
Field('name', css_class='name-class'),
Field('age', css_class='age-class'),
Field('django_hacker', css-class='hacker-class'),
FormActions(
Submit('save_changes', 'Save changes'),
)
)
The steps you listed will work, but there's a longer way that gives you more options:
git checkout dmgr2 # gets you "on branch dmgr2"
git fetch origin # gets you up to date with origin
git merge origin/master
The fetch
command can be done at any point before the merge
, i.e., you can swap the order of the fetch and the checkout, because fetch
just goes over to the named remote (origin
) and says to it: "gimme everything you have that I don't", i.e., all commits on all branches. They get copied to your repository, but named origin/branch
for any branch named branch
on the remote.
At this point you can use any viewer (git log
, gitk
, etc) to see "what they have" that you don't, and vice versa. Sometimes this is only useful for Warm Fuzzy Feelings ("ah, yes, that is in fact what I want") and sometimes it is useful for changing strategies entirely ("whoa, I don't want THAT stuff yet").
Finally, the merge
command takes the given commit, which you can name as origin/master
, and does whatever it takes to bring in that commit and its ancestors, to whatever branch you are on when you run the merge
. You can insert --no-ff
or --ff-only
to prevent a fast-forward, or merge only if the result is a fast-forward, if you like.
When you use the sequence:
git checkout dmgr2
git pull origin master
the pull
command instructs git to run git fetch
, and then the moral equivalent of git merge origin/master
. So this is almost the same as doing the two steps by hand, but there are some subtle differences that probably are not too concerning to you. (In particular the fetch
step run by pull
brings over only origin/master
, and it does not update the ref in your repo:1 any new commits winds up referred-to only by the special FETCH_HEAD
reference.)
If you use the more-explicit git fetch origin
(then optionally look around) and then git merge origin/master
sequence, you can also bring your own local master
up to date with the remote, with only one fetch
run across the network:
git fetch origin
git checkout master
git merge --ff-only origin/master
git checkout dmgr2
git merge --no-ff origin/master
for instance.
1This second part has been changed—I say "fixed"—in git 1.8.4, which now updates "remote branch" references opportunistically. (It was, as the release notes say, a deliberate design decision to skip the update, but it turns out that more people prefer that git update it. If you want the old remote-branch SHA-1, it defaults to being saved in, and thus recoverable from, the reflog. This also enables a new git 1.9/2.0 feature for finding upstream rebases.)
I use MVVM, so I created some attached properties of my own, using Thomas's as a reference. It does sorting on one column at a time when you click on the header, toggling between Ascending and Descending. It sorts from the very beginning using the first column. And it shows Win7/8 style glyphs.
Normally, all you have to do is set the main property to true (but you have to explicitly declare the GridViewColumnHeaders):
<Window xmlns:local="clr-namespace:MyProjectNamespace">
<Grid>
<ListView local:App.EnableGridViewSort="True" ItemsSource="{Binding LVItems}">
<ListView.View>
<GridView>
<GridViewColumn DisplayMemberBinding="{Binding Property1}">
<GridViewColumnHeader Content="Prop 1" />
</GridViewColumn>
<GridViewColumn DisplayMemberBinding="{Binding Property2}">
<GridViewColumnHeader Content="Prop 2" />
</GridViewColumn>
</GridView>
</ListView.View>
</ListView>
</Grid>
<Window>
If you want to sort on a different property than the display, than you have to declare that:
<GridViewColumn DisplayMemberBinding="{Binding Property3}"
local:App.GridViewSortPropertyName="Property4">
<GridViewColumnHeader Content="Prop 3" />
</GridViewColumn>
Here's the code for the attached properties, I like to be lazy and put them in the provided App.xaml.cs:

You'll have to pass the new ordinal position to insert
using len
in this case:
In [62]:
a=[1,2,3,4]
a.insert(len(a),5)
a
Out[62]:
[1, 2, 3, 4, 5]
There is one last language feature where the distinction is important. Consider the following function:
def foo(*positional, **keywords):
print "Positional:", positional
print "Keywords:", keywords
The *positional
argument will store all of the positional arguments passed to foo()
, with no limit to how many you can provide.
>>> foo('one', 'two', 'three')
Positional: ('one', 'two', 'three')
Keywords: {}
The **keywords
argument will store any keyword arguments:
>>> foo(a='one', b='two', c='three')
Positional: ()
Keywords: {'a': 'one', 'c': 'three', 'b': 'two'}
And of course, you can use both at the same time:
>>> foo('one','two',c='three',d='four')
Positional: ('one', 'two')
Keywords: {'c': 'three', 'd': 'four'}
These features are rarely used, but occasionally they are very useful, and it's important to know which arguments are positional or keywords.
There's the Managed Script Plugin which provides an easy way of managing user scripts. It also adds a build step action which allows you to select which user script to execute.
public class MyExceptionClass : Exception
{
public MyExceptionClass(string message,
Exception innerException): base(message, innerException)

You can pass inner exception to one of the constructors.
Thinking about a Map with 2 keys immediately compelled me to use a user-defined key, and that would probably be a Class. Following is the key Class:
public class MapKey {
private Object key1;
private Object key2;
public Object getKey1() {
return key1;
}
public void setKey1(Object key1) {
this.key1 = key1;
}
public Object getKey2() {
return key2;
}
public void setKey2(Object key2) {
this.key2 = key2;
}
}
// Create first map entry with key <A,B>.
MapKey mapKey1 = new MapKey();
mapKey1.setKey1("A");
mapKey1.setKey2("B");
I simply use this jQuery trick:
$("a:focus").attr('data-id');
It gets the focused a
element and gets the data-id
attribute from it.
