You need to extract the base64 image data from that string, decode it and then you can save it to disk, you don't need GD since it already is a png.
$data = 'data:image/png;base64,AAAFBfj42Pj4';
list($type, $data) = explode(';', $data);
list(, $data) = explode(',', $data);
$data = base64_decode($data);
file_put_contents('/tmp/image.png', $data);
And as a one-liner:
$data = base64_decode(preg_replace('#^data:image/\w+;base64,#i', '', $data));
An efficient method for extracting, decoding, and checking for errors is:
if (preg_match('/^data:image\/(\w+);base64,/', $data, $type)) {
$data = substr($data, strpos($data, ',') + 1);
$type = strtolower($type[1]); // jpg, png, gif
if (!in_array($type, [ 'jpg', 'jpeg', 'gif', 'png' ])) {
throw new \Exception('invalid image type');
}
$data = str_replace( ' ', '+', $data );
$data = base64_decode($data);
if ($data === false) {
throw new \Exception('base64_decode failed');
}
} else {
throw new \Exception('did not match data URI with image data');
}
file_put_contents("img.{$type}", $data);
You can use it as follows,
<td>
<input type="submit" name="save" class="noborder" id="save" value="Save" alt="Save"
tabindex="4" />
</td>
<td>
<input type="submit" name="publish" class="noborder" id="publish" value="Publish"
alt="Publish" tabindex="5" />
</td>
And in PHP,
<?php
if($_POST['save'])
{
//Save Code
}
else if($_POST['publish'])
{
//Publish Code
}
?>
Regarding point 2 I'm using a simple batch file that is populating PATH
or other environment variables for me. Therefore, there is no pollution of environment variables by default. This batch file is accessible from everywhere so I can type:
c:\>mybatchfile
-- here all env. are available
c:\>php file.php

I have experienced this problem too while developing an application for a customer that wanted to have videos offline available from their application. I have written a blogpost about why the app I worked on for months wouldn't show up in the play store for my device (post can be found here). I found the same as @Greg Hewgill found: Cache partition limitations on some devices.
The journey didn't stop for me there. The customer wanted to have these videos in the application and didn't want the quality of the video to be decreased. After some research I figured out that using expansion files was the perfect solution to our problem.
To share my knowledge with the Android community I held a talk at droidconNL 2012 about expansion files. I created a presentation and sample code to illustrate how easy it can be to start using expansion files. For any of you out there wanting to use expansion files to solve this problem feel free to check out the post containing the presentation and the sample code
Modern Solution
The result is that the circle never gets distorted and the text stays exactly in the middle of the circle - vertically and horizontally.
.circle {
background: gold;
width: 40px;
height: 40px;
border-radius: 50%;
display: flex; /* or inline-flex */
align-items: center;
justify-content: center;
}
_x000D_
<div class="circle">text</div>
_x000D_
Simple and easy to use. Enjoy!
Rather than worry about dealing with the keyboard, why not just accept any input, lowercase or uppercase and convert the string to uppercase?
The following code should help:
EditText edit = (EditText)findViewById(R.id.myEditText);
String input;
....
input = edit.getText();
input = input.toUpperCase(); //converts the string to uppercase
This is user-friendly since it is unnecessary for the user to know that you need the string in uppercase. Hope this helps.
1). You can use getter methods from WC_Order
and WC_Abstract_Order
classes on the WC_Order
object instance like:
// Get an instance of the WC_Order Object from the Order ID (if required)
$order = wc_get_order( $order_id );
// Get the Customer ID (User ID)
$customer_id = $order->get_customer_id(); // Or $order->get_user_id();
// Get the WP_User Object instance
$user = $order->get_user();
// Get the WP_User roles and capabilities
$user_roles = $user->roles;
// Get the Customer billing email
$billing_email = $order->get_billing_email();
// Get the Customer billing phone
$billing_phone = $order->get_billing_phone();
// Customer billing information details
$billing_first_name = $order->get_billing_first_name();
$billing_last_name = $order->get_billing_last_name();
$billing_company = $order->get_billing_company();
$billing_address_1 = $order->get_billing_address_1();
$billing_address_2 = $order->get_billing_address_2();
$billing_city = $order->get_billing_city();
$billing_state = $order->get_billing_state();
$billing_postcode = $order->get_billing_postcode();
$billing_country = $order->get_billing_country();
// Customer shipping information details
$shipping_first_name = $order->get_shipping_first_name();
$shipping_last_name = $order->get_shipping_last_name();
$shipping_company = $order->get_shipping_company();
$shipping_address_1 = $order->get_shipping_address_1();
$shipping_address_2 = $order->get_shipping_address_2();
$shipping_city = $order->get_shipping_city();
$shipping_state = $order->get_shipping_state();
$shipping_postcode = $order->get_shipping_postcode();
$shipping_country = $order->get_shipping_country();
2). You can also use the WC_Order
get_data()
method, to get an unprotected data array from Order meta data like:
// Get an instance of the WC_Order Object from the Order ID (if required)
$order = wc_get_order( $order_id );
// Get the Order meta data in an unprotected array
$data = $order->get_data(); // The Order data
$order_id = $data['id'];
$order_parent_id = $data['parent_id'];
// Get the Customer ID (User ID)
$customer_id = $data['customer_id'];
## BILLING INFORMATION:
$billing_email = $data['billing']['email'];
$billing_phone = $order_data['billing']['phone'];
$billing_first_name = $data['billing']['first_name'];
$billing_last_name = $data['billing']['last_name'];
$billing_company = $data['billing']['company'];
$billing_address_1 = $data['billing']['address_1'];
$billing_address_2 = $data['billing']['address_2'];
$billing_city = $data['billing']['city'];
$billing_state = $data['billing']['state'];
$billing_postcode = $data['billing']['postcode'];
$billing_country = $data['billing']['country'];
## SHIPPING INFORMATION:
$shipping_first_name = $data['shipping']['first_name'];
$shipping_last_name = $data['shipping']['last_name'];
$shipping_company = $data['shipping']['company'];
$shipping_address_1 = $data['shipping']['address_1'];
$shipping_address_2 = $data['shipping']['address_2'];
$shipping_city = $data['shipping']['city'];
$shipping_state = $data['shipping']['state'];
$shipping_postcode = $data['shipping']['postcode'];
$shipping_country = $data['shipping']['country'];
Now to get the user account data (from an Order ID):
1). You can use the methods from WC_Customer
Class:
// Get the user ID from an Order ID
$user_id = get_post_meta( $order_id, '_customer_user', true );
// Get an instance of the WC_Customer Object from the user ID
$customer = new WC_Customer( $user_id );
$username = $customer->get_username(); // Get username
$user_email = $customer->get_email(); // Get account email
$first_name = $customer->get_first_name();
$last_name = $customer->get_last_name();
$display_name = $customer->get_display_name();
// Customer billing information details (from account)
$billing_first_name = $customer->get_billing_first_name();
$billing_last_name = $customer->get_billing_last_name();
$billing_company = $customer->get_billing_company();
$billing_address_1 = $customer->get_billing_address_1();
$billing_address_2 = $customer->get_billing_address_2();
$billing_city = $customer->get_billing_city();
$billing_state = $customer->get_billing_state();
$billing_postcode = $customer->get_billing_postcode();
$billing_country = $customer->get_billing_country();
// Customer shipping information details (from account)
$shipping_first_name = $customer->get_shipping_first_name();
$shipping_last_name = $customer->get_shipping_last_name();
$shipping_company = $customer->get_shipping_company();
$shipping_address_1 = $customer->get_shipping_address_1();
$shipping_address_2 = $customer->get_shipping_address_2();
$shipping_city = $customer->get_shipping_city();
$shipping_state = $customer->get_shipping_state();
$shipping_postcode = $customer->get_shipping_postcode();
$shipping_country = $customer->get_shipping_country();
2). The WP_User
object (WordPress):
// Get the user ID from an Order ID
$user_id = get_post_meta( $order_id, '_customer_user', true );
// Get the WP_User instance Object
$user = new WP_User( $user_id );
$username = $user->username; // Get username
$user_email = $user->email; // Get account email
$first_name = $user->first_name;
$last_name = $user->last_name;
$display_name = $user->display_name;
// Customer billing information details (from account)
$billing_first_name = $user->billing_first_name;
$billing_last_name = $user->billing_last_name;
$billing_company = $user->billing_company;
$billing_address_1 = $user->billing_address_1;
$billing_address_2 = $user->billing_address_2;
$billing_city = $user->billing_city;
$billing_state = $user->billing_state;
$billing_postcode = $user->billing_postcode;
$billing_country = $user->billing_country;
// Customer shipping information details (from account)
$shipping_first_name = $user->shipping_first_name;
$shipping_last_name = $user->shipping_last_name;
$shipping_company = $user->shipping_company;
$shipping_address_1 = $user->shipping_address_1;
$shipping_address_2 = $user->shipping_address_2;
$shipping_city = $user->shipping_city;
$shipping_state = $user->shipping_state;
$shipping_postcode = $user->shipping_postcode;
$shipping_country = $user->shipping_country;

To use multiple files from node_modules in html, the best way I've found is to put them to an array and then loop on them to make them visible for web clients, for example to use filepond modules from node_modules:
const filePondModules = ['filepond-plugin-file-encode', 'filepond-plugin-image-preview', 'filepond-plugin-image-resize', 'filepond']
filePondModules.forEach(currentModule => {
let module_dir = require.resolve(currentModule)
.match(/.*\/node_modules\/[^/]+\//)[0];
app.use('/' + currentModule, express.static(module_dir + 'dist/'));
})
And then in the html (or layout) file, just call them like this :
<link rel="stylesheet" href="/filepond/filepond.css">
<link rel="stylesheet" href="/filepond-plugin-image-preview/filepond-plugin-image-preview.css">
...
<script src="/filepond-plugin-image-preview/filepond-plugin-image-preview.js" ></script>
<script src="/filepond-plugin-file-encode/filepond-plugin-file-encode.js"></script>
<script src="/filepond-plugin-image-resize/filepond-plugin-image-resize.js"></script>
<script src="/filepond/filepond.js"></script>
EDIT [Added suggestion from Dan Nissenbaum]:
By one convention, .hpp files are used when the prototypes are defined in the header itself. Such definitions in headers are useful in case of templates, since the compiler generates the code for each type only on template instantiation. Hence, if they are not defined in header files, their definitions will not be resolved at link time from other compilation units. If your project is a C++ only project that makes heavy use of templates, this convention will be useful.
Certain template libraries that adhere to this convention provide headers with .hpp extensions to indicate that they do not have corresponding .cpp files.
another convention is to use .h for C headers and .hpp for C++; a good example would be the boost library.
Quote from Boost FAQ,
File extensions communicate the "type" of the file, both to humans and to computer programs. The '.h' extension is used for C header files, and therefore communicates the wrong thing about C++ header files. Using no extension communicates nothing and forces inspection of file contents to determine type. Using '.hpp' unambiguously identifies it as C++ header file, and works well in actual practice. (Rainer Deyke)

If for some reason it's still not working. First option for Laravel The second option for any application
FIRST OPTION:
As in the example above, we create middleware
php artisan make:middleware Cors
Add the following code to app/Http/Middleware/Cors.php
:
public function handle($request, Closure $next)
{
return $next($request)
->header('Access-Control-Allow-Origin', '*')
->header('Access-Control-Allow-Methods', 'GET, POST, PUT, PATCH, DELETE, OPTIONS')
->header('Access-Control-Allow-Headers', 'Authorization,Accept,Origin,DNT,X-CustomHeader,Keep-Alive,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type,Content-Range,Range');
}
Look closely, the amount of data in the header ->header('Access-Control-Allow-Headers',
Step three, add middleware to $routeMiddleware
array in app/Http/Kernel.php
protected $routeMiddleware = [
....
'cors' => \App\Http\Middleware\Cors::class,
];
SECOND OPTION:
Open the nginx.conf settings for your domain.
sudo nano /etc/nginx/sites-enabled/your-domain.conf
Inside the server settings server { listen 80; .... }
please add the following code:
add_header 'Access-Control-Allow-Origin' '*';
add_header 'Access-Control-Allow-Credentials' 'true';
add_header 'Access-Control-Allow-Headers' 'Authorization,Accept,Origin,DNT,X-CustomHeader,Keep-Alive,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type,Content-Range,Range';
add_header 'Access-Control-Allow-Methods' 'GET,POST,OPTIONS,PUT,DELETE,PATCH';

$mac = exec($macCommandString);
return ['ip' => $ipaddress, 'mac' => $mac];
}
I know this is an older question, but I wanted to post an answer for users with the same question:
curl -H 'Cache-Control: no-cache' http://www.example.com
This curl command servers in its header request to return non-cached data from the web server.
The below piece worked for me:
>>>import imp;
>>>fp, pathname, description = imp.find_module("/home/test_module");
>>>test_module = imp.load_module("test_module", fp, pathname, description);
>>>print test_module.print_hello();
if you want to import in shell-script:
python -c '<above entire code in one line>'
And what about: require_relative *Dir['relative path']
?
Warning: A component is changing an uncontrolled input of type text to be controlled. Input elements should not switch from uncontrolled to controlled (or vice versa). Decide between using a controlled or uncontrolled input element for the lifetime of the component.
Solution : Check if value is not undefined
React / Formik / Bootstrap / TypeScript
example :
{ values?.purchaseObligation.remainingYear ?
<Input
tag={Field}
name="purchaseObligation.remainingYear"
type="text"
component="input"
/> : null
}
This should get you for starting with two letters and ending with two numbers.
[A-Za-z]{2}(.*)[0-9]{2}
If you know it will always be just two and two you can
[A-Za-z]{2}[0-9]{2}
For posix (Linux, BSD, etc... only need /proc directory to be mounted) it's easier to work with os files in /proc. It's pure python, no need to call shell programs outside.
Works on python 2 and 3 ( The only difference (2to3) is the Exception tree, therefore the "except Exception", which I dislike but kept to maintain compatibility. Also could've created a custom exception.)
#!/usr/bin/env python
import os
import sys
for dirname in os.listdir('/proc'):
if dirname == 'curproc':
continue
try:
with open('/proc/{}/cmdline'.format(dirname), mode='rb') as fd:
content = fd.read().decode().split('\x00')
except Exception:
continue
for i in sys.argv[1:]:
if i in content[0]:
print('{0:<12} : {1}'.format(dirname, ' '.join(content)))
Sample Output (it works like pgrep):
phoemur ~/python $ ./pgrep.py bash
1487 : -bash
1779 : /bin/bash
You can validate that and much more by using an XML schema language, like XSD.
If you mean conditionally, within code, then XPath is worth a look as well.
Please do not use the variant with delete
- it makes a hole in the array as it does not re-index the elements after the deleted item.
> Array.prototype.remove=function(v){
... delete this[this.indexOf(v)]
... };
[Function]
> var myarray=["3","24","55","2"];
undefined
> myarray.remove("55");
undefined
> myarray
[ '3', '24', , '2' ]
Just add parameters, split by comma:
UPDATE tablename SET column1 = "value1", column2 = "value2" ....

Flutter is designed to use the latest Android version installed. So if you have an incomplete download of the latest Android, Flutter will try to use that.
So either complete the installation or delete the complete installation. You can find the Android versions at: /home/{user}/Android/Sdk/platforms/android-29/android.jar
Calling
$state.go($state.current, {myParam: newValue}, {notify: false});
will still reload the controller, meaning you will lose state data.
To avoid it, simply declare the parameter as dynamic:
$stateProvider.state({
name: 'myState',
url: '/my_state?myParam',
params: {
myParam: {
dynamic: true, // <----------
}
},
...
});
Then you don't even need the notify
, just calling
$state.go($state.current, {myParam: newValue})
suffices. Neato!
From the documentation:
When
dynamic
istrue
, changes to the parameter value will not cause the state to be entered/exited. The resolves will not be re-fetched, nor will views be reloaded.This can be useful to build UI where the component updates itself when the param values change.
The easiest way I've found to place objects on the left is using FlowLayout.
JPanel panel = new JPanel(new FlowLayout(FlowLayout.LEFT));
adding a component normally to this panel will place it on the left
The most significant advantage of shared libraries is that there is only one copy of code loaded in memory, no matter how many processes are using the library. For static libraries each process gets its own copy of the code. This can lead to significant memory wastage.
OTOH, a advantage of static libraries is that everything is bundled into your application. So you don't have to worry that the client will have the right library (and version) available on their system.
To have a consistent flow of the images on different devices, you'd have to specify the width and height value for each carousel image item, for instance here in my example the image would take the full width but with a height of "400px" (you can specify your personal value instead)
<div class="item">
<img src="image.jpg" style="width:100%; height: 400px;">
</div>
strtotime returns the current timestamp and date is to format timestamp
$date=strtotime(date("h:i:sa"))+900;//15*60=900 seconds
$date=date("h:i:sa",$date);
This will add 15 mins to the current time
This error can also occur when you try to connect to http while the server is on https.
It was a bit confusing because my get-requests were OK, the problem was only present with post-requests.

Put the entire script into a template string, with {SERVERNAME} placeholders. Then edit the string using:
SET @SQL_SCRIPT = REPLACE(@TEMPLATE, '{SERVERNAME}', @DBNAME)
and then run it with
EXECUTE (@SQL_SCRIPT)
It's hard to believe that, in the course of three years, nobody noticed that my code doesn't work!
You can't EXEC
multiple batches. GO
is a batch separator, not a T-SQL statement. It's necessary to build three separate strings, and then to EXEC
each one after substitution.
I suppose one could do something "clever" by breaking the single template string into multiple rows by splitting on GO
; I've done that in ADO.NET code.
And where did I get the word "SERVERNAME" from?
Here's some code that I just tested (and which works):
DECLARE @DBNAME VARCHAR(255)
SET @DBNAME = 'TestDB'
DECLARE @CREATE_TEMPLATE VARCHAR(MAX)
DECLARE @COMPAT_TEMPLATE VARCHAR(MAX)
DECLARE @RECOVERY_TEMPLATE VARCHAR(MAX)
SET @CREATE_TEMPLATE = 'CREATE DATABASE {DBNAME}'
SET @COMPAT_TEMPLATE='ALTER DATABASE {DBNAME} SET COMPATIBILITY_LEVEL = 90'
SET @RECOVERY_TEMPLATE='ALTER DATABASE {DBNAME} SET RECOVERY SIMPLE'
DECLARE @SQL_SCRIPT VARCHAR(MAX)
SET @SQL_SCRIPT = REPLACE(@CREATE_TEMPLATE, '{DBNAME}', @DBNAME)
EXECUTE (@SQL_SCRIPT)
SET @SQL_SCRIPT = REPLACE(@COMPAT_TEMPLATE, '{DBNAME}', @DBNAME)
EXECUTE (@SQL_SCRIPT)
SET @SQL_SCRIPT = REPLACE(@RECOVERY_TEMPLATE, '{DBNAME}', @DBNAME)
EXECUTE (@SQL_SCRIPT)

Instead of having to add the top

, left
, and right
classes to every <td>
, all I have to do is add top row
to the top <tr>
, bottom row
to the bottom <tr>
, and row
to every <tr>
in between. Is there anything wrong with this solution? Are there any cross-platform issues I should be aware of?
Negative numbers mean that you count from the right instead of the left. So, list[-1]
refers to the last element, list[-2]
is the second-last, and so on.
You can also install it using conda (tested on Ubuntu):
conda create --name csharp
conda activate csharp
conda install -c conda-forge mono
var origParseFloat = parseFloat;
parseFloat = function(str) {
alert("And I'm in your floats!");
return origParseFloat(str);
}
There is now a built-in way to do this as of version 6.5.2

this post was made a while ago, but it provides an answer that did not solve the problem regarding reaching the limit of requests in an iteration for me, so I publish this, to help who else has not served.
My environment happened in Ionic 3.
Instead of making a "pause" in the iteration, I ocurred the idea of ??iterating with a timer
, this timer has the particularity of executing the code that would go in the iteration, but will run every so often until it is reached the maximum count of the "Array" in which we want to iterate.
In other words, we will consult the Google API in a certain time so that it does not exceed the limit allowed in milliseconds.
// Code to start the timer
this.count= 0;
let loading = this.loadingCtrl.create({
content: 'Buscando los mejores servicios...'
});
loading.present();
this.interval = setInterval(() => this.getDistancias(loading), 40);
// Function that runs the timer, that is, query Google API
getDistancias(loading){
if(this.count>= this.datos.length){
clearInterval(this.interval);
} else {
var sucursal = this.datos[this.count];
this.calcularDistancia(this.posicion, new LatLng(parseFloat(sucursal.position.latitude),parseFloat(sucursal.position.longitude)),sucursal.codigo).then(distancia => {
}).catch(error => {
console.log('error');
console.log(error);
});
}
this.count += 1;
}
calcularDistancia(miPosicion, markerPosicion, codigo){
return new Promise(async (resolve,reject) => {
var service = new google.maps.DistanceMatrixService;
var distance;
var duration;
service.getDistanceMatrix({
origins: [miPosicion, 'salida'],
destinations: [markerPosicion, 'llegada'],
travelMode: 'DRIVING',
unitSystem: google.maps.UnitSystem.METRIC,
avoidHighways: false,
avoidTolls: false
}, function(response, status){
if (status == 'OK') {
var originList = response.originAddresses;
var destinationList = response.destinationAddresses;
try{
if(response != null && response != undefined){
distance = response.rows[0].elements[0].distance.value;
duration = response.rows[0].elements[0].duration.text;
resolve(distance);
}
}catch(error){
console.log("ERROR GOOGLE");
console.log(status);
}
}
});
});
}
I hope this helps!
I'm sorry for my English, I hope it's not an inconvenience, I had to use the Google translator.

The shortest and easiest answer is: you shouldn't vertically center things in webpages. HTML and CSS simply are not created with that in mind. They are text formatting languages, not user interface design languages.
That said, this is the best way I can think of. However, this will NOT WORK in Internet Explorer 7 and below!
<style>
html, body {
height: 100%;
}
#tableContainer-1 {
height: 100%;
width: 100%;
display: table;
}
#tableContainer-2 {
vertical-align: middle;
display: table-cell;
height: 100%;
}
#myTable {
margin: 0 auto;
}
</style>
<div id="tableContainer-1">
<div id="tableContainer-2">
<table id="myTable" border>
<tr><td>Name</td><td>J W BUSH</td></tr>
<tr><td>Proficiency</td><td>PHP</td></tr>
<tr><td>Company</td><td>BLAH BLAH</td></tr>
</table>
</div>
</div>
Its undefined
because, console.log(response)
runs before doCall(urlToCall);
is finished. You have to pass in a callback function aswell, that runs when your request is done.
First, your function. Pass it a callback:
function doCall(urlToCall, callback) {
urllib.request(urlToCall, { wd: 'nodejs' }, function (err, data, response) {
var statusCode = response.statusCode;
finalData = getResponseJson(statusCode, data.toString());
return callback(finalData);
});
}
Now:
var urlToCall = "http://myUrlToCall";
doCall(urlToCall, function(response){
// Here you have access to your variable
console.log(response);
})
@Rodrigo, posted a good resource in the comments. Read about callbacks in node and how they work. Remember, it is asynchronous code.

The ASCII table is arranged so that the value of the character '9'
is nine greater than the value of '0'
; the value of the character '8'
is eight greater than the value of '0'
; and so on.
So you can get the int value of a decimal digit char by subtracting '0'
.
char x = '9';
int y = x - '0'; // gives the int value 9
What you're asking about is multiple inheritance, and it's very problematic for a number of reasons. Multiple inheritance was specifically avoided in Java; the choice was made to support multiple interface implementation, instead, which is the appropriate workaround.
A workaround is to transpose the DataFrame
and iterate over the rows.
for column_name, column in df.transpose().iterrows():
print column_name
What's you've got there should be fine to work, but there is no actual "Is Mobile/Tablet" media query so you're always going to be stuck.
There are media queries for common breakpoints , but with the ever changing range of devices they're not guaranteed to work moving forwards.
The idea is that your site maintains the same brand across all sizes, so you should want the styles to cascade across the breakpoints and only update the widths and positioning to best suit that viewport.
To further the answer above, using Modernizr with a no-touch test will allow you to target touch devices which are most likely tablets and smart phones, however with the new releases of touch based screens that is not as good an option as it once was.
ITroubs answer doesn't deal with the left over seconds when you want to use this code to convert an amount of seconds to a time format like hours : minutes : seconds
Here is what I did to deal with this: (This also adds a leading zero to one-digit minutes and seconds)
$seconds = 3921; //example
$hours = floor($seconds / 3600);
$mins = floor(($seconds - $hours*3600) / 60);
$s = $seconds - ($hours*3600 + $mins*60);
$mins = ($mins<10?"0".$mins:"".$mins);
$s = ($s<10?"0".$s:"".$s);
$time = ($hours>0?$hours.":":"").$mins.":".$s;
$time will contain "1:05:21" in this example.
Go back in to where you added the jar. I believe its the libraries tab, I don't have Eclipse open but that sounds right. to the left of the jar file you added there should be an arrow pointing right, click that and 3 or 4 options expand, one of them being the source file of the library. Click on that and click edit(I think you can also double click it) then locate the file or folder on your hard disk, you probably have to click apply or okay and you're good to go, same with javadoc and i think the last one is native libraries. I don't pay much attention when I'm in there anymore if you couldn't tell. That's what you were asking, right?
emplace_back
shouldn't take an argument of type vector::value_type
, but instead variadic arguments that are forwarded to the constructor of the appended item.
template <class... Args> void emplace_back(Args&&... args);
It is possible to pass a value_type
which will be forwarded to the copy constructor.
Because it forwards the arguments, this means that if you don't have rvalue, this still means that the container will store a "copied" copy, not a moved copy.
std::vector<std::string> vec;
vec.emplace_back(std::string("Hello")); // moves
std::string s;
vec.emplace_back(s); //copies
But the above should be identical to what push_back
does. It is probably rather meant for use cases like:
std::vector<std::pair<std::string, std::string> > vec;
vec.emplace_back(std::string("Hello"), std::string("world"));
// should end up invoking this constructor:
//template<class U, class V> pair(U&& x, V&& y);
//without making any copies of the strings
I think this is because you are using client software and not the server.
mysql
is client mysqld
is the serverTry:
sudo service mysqld start
To check that service is running use: ps -ef | grep mysql | grep -v grep
.
Uninstalling:
sudo apt-get purge mysql-server
sudo apt-get autoremove
sudo apt-get autoclean
Re-Installing:
sudo apt-get update
sudo apt-get install mysql-server
Backup entire folder before doing this:

You need to create a popover instance that has the html option enabled (place this in your javascript file after the popover JS code):

To make a fill completely transparent, fill="transparent"

Yes, it is asking for the application/executable that is capable of creating Javadoc. There is a javadoc

I always liked going after it directly:

if (isNaN(day) || isNaN(month) || isNaN(year))
return null;
var result = new Date(year, (month - 1), day);

This error occurred for me when using window.location.reload()

There is no such font as “Calibri (Body)”. You probably saw this string in Microsoft Word font selection menu, but it’s not a font name (see e.g. the explanation Font: +body (in W07)).
So use just font-family: Calibri
or, better, font-family: Calibri, sans-serif
. (There is no adequate backup font for Calibri, but the odds are that when Calibri is not available, the browser’s default sans-serif font suits your design better than the browser’s default font, which is most often a serif font.)
you should man date
first
date +%Y-%m-%d
date +%Y-%m-%d -d yesterday
Based on the answer from Luis, you can do something more like the default findBy method.
First, create a default repository class that is going to be used by all your entities.
/* $config is the entity manager configuration object. */
$config->setDefaultRepositoryClassName( 'MyCompany\Repository' );
Or you can edit this in config.yml
doctrine: orm: default_repository_class: MyCompany\Repository
Then:
<?php
namespace MyCompany;
use Doctrine\ORM\EntityRepository;
class Repository extends EntityRepository {
public function findByNot( array $criteria, array $orderBy = null, $limit = null, $offset = null )
{
$qb = $this->getEntityManager()->createQueryBuilder();
$expr = $this->getEntityManager()->getExpressionBuilder();
$qb->select( 'entity' )
->from( $this->getEntityName(), 'entity' );
foreach ( $criteria as $field => $value ) {
// IF INTEGER neq, IF NOT notLike
if($this->getEntityManager()->getClassMetadata($this->getEntityName())->getFieldMapping($field)["type"]=="integer") {
$qb->andWhere( $expr->neq( 'entity.' . $field, $value ) );
} else {
$qb->andWhere( $expr->notLike( 'entity.' . $field, $qb->expr()->literal($value) ) );
}
}
if ( $orderBy ) {
foreach ( $orderBy as $field => $order ) {
$qb->addOrderBy( 'entity.' . $field, $order );
}
}
if ( $limit )
$qb->setMaxResults( $limit );
if ( $offset )
$qb->setFirstResult( $offset );
return $qb->getQuery()
->getResult();
}
}
The usage is the same than the findBy method, example:
$entityManager->getRepository( 'MyRepo' )->findByNot(
array( 'status' => Status::STATUS_DISABLED )
);
If you are using Underscore.js or Lodash, there is a function 'omit' that will do it.
http://underscorejs.org/#omit
var thisIsObject= {
'Cow' : 'Moo',
'Cat' : 'Meow',
'Dog' : 'Bark'
};
_.omit(thisIsObject,'Cow'); //It will return a new object
=> {'Cat' : 'Meow', 'Dog' : 'Bark'} //result
If you want to modify the current object, assign the returning object to the current object.
thisIsObject = _.omit(thisIsObject,'Cow');
With pure JavaScript, use:
delete thisIsObject['Cow'];
Another option with pure JavaScript.
thisIsObject.cow = undefined;
thisIsObject = JSON.parse(JSON.stringify(thisIsObject ));

},
{
image:require('../../../src/assets/group/kids_room2.png')
}

}
]
}
when press the button-(i select image random number betwenn 0-2))
let setImage=>(){
//set new dynamic image
this.setState({newimage:this.state.randomImages[Math.floor(Math.random() * 3)];
})
}

source={this.state.newimage}

You can create your <script>
element with an "onload" handler, and that will be called when the script has been loaded and evaluated by the browser.
var script = document.createElement('script');
script.onload = function() {
alert("Script loaded and ready");
};
script.src = "http://whatever.com/the/script.js";
document.getElementsByTagName('head')[0].appendChild(script);
You can't do it synchronously.
edit — it's been pointed out that, true to form, IE doesn't fire a "load" event on <script>
tags being loaded/evaluated. Thus I suppose the next thing to do would be to fetch the script with an XMLHttpRequest and then eval()
it yourself. (Or, I suppose, stuff the text into a <script>
tag you add; the execution environment of eval()
is affected by the local scope, so it won't necessarily do what you want it to do.)
edit — As of early 2013, I'd strongly advise looking into a more robust script loading tool like Requirejs. There are a lot of special cases to worry about. For really simple situations, there's yepnope, which is now built into Modernizr.
For anyone looking for a clean way to encode a POST request in Swift 5.
You don’t need to deal with manually adding percent encoding.
Use URLComponents
to create a GET request URL. Then use query
property of that URL to get properly percent escaped query string.
let url = URL(string: "https://example.com")!
var components = URLComponents(url: url, resolvingAgainstBaseURL: false)!
components.queryItems = [
URLQueryItem(name: "key1", value: "NeedToEscape=And&"),
URLQueryItem(name: "key2", value: "vålüé")
]
let query = components.url!.query
The query
will be a properly escaped string:
key1=NeedToEscape%3DAnd%26&key2=v%C3%A5l%C3%BC%C3%A9
Now you can create a request and use the query as HTTPBody:
var request = URLRequest(url: url)
request.httpMethod = "POST"
request.httpBody = Data(query.utf8)
Now you can send the request.
I came here because I had the same problem.
What was the problem for me was that the procedure was defined in the package body, but not in the package header.
I was executing my function with a lose BEGIN END statement.
If you want to make a row (or subset of rows) non-selectable, implement the UITableViewDelegate
method -tableView:willSelectRowAtIndexPath:
(also mentioned by TechZen). If the indexPath
should be not be selectable, return nil
, otherwise return the indexPath
. To get the default selection behavior, you just return the indexPath
passed to your delegate
method, but you can also alter the row selection by returning a different indexPath
.
example:
- (NSIndexPath *)tableView:(UITableView *)tableView willSelectRowAtIndexPath:(NSIndexPath *)indexPath {
// rows in section 0 should not be selectable
if ( indexPath.section == 0 ) return nil;
// first 3 rows in any section should not be selectable
if ( indexPath.row <= 2 ) return nil;
// By default, allow row to be selected
return indexPath;
}
You are using a transaction; autocommit does not disable transactions, it just makes them automatically commit at the end of the statement.
What is happening is, some other thread is holding a record lock on some record (you're updating every record in the table!) for too long, and your thread is being timed out.
You can see more details of the event by issuing a
SHOW ENGINE INNODB STATUS
after the event (in sql
editor). Ideally do this on a quiet test-machine.
In iOS 7 status bar appearance depends on UIViewController
as default. To hide status bar globally, in info.plist
use NO
value for UIViewControllerBasedStatusBarAppearance
key and use UIApplication
's setStatusBarHidden
method with YES
BOOL
value.
Simple and easy way to see database content within Android studio.
You can use a very simple Android Studio's feature Database Inspector. Where you can inspect, query, and modify your app’s databases using the new Database Inspector. For example, you can debug your running app by modifying values in your database and testing those changes on the device in real-time without leaving Android Studio.
To get started, deploy your app to a device running API level 26 or higher and select View > Tool Windows > Database Inspector from the menu bar.
First, install Database Navigator plugin in Android Studio
Second, Restart Android Studio
Third, save the database into the default location like: (C:\Users\User Name\Documents\AndroidStudio\DeviceExplorer\emulator or device\data\data\package name\databases)
Fourth, Connect saved dbname_db file in Database Navigator
Give same DB file path that is used in step Third
i.e (C:\Users\User Name\Documents\AndroidStudio\DeviceExplorer\emulator or device\data\data\package name\databases\package naem\dbname_db)
Finally, just test DB connection and open console and do whatever you want to do.
If you want to refresh DB just repeat step Second and just save it or refresh.
HAPPY CODING!!!!!
Foreword: Without arguing that if else
is the way to go, we can still play with and find pleasure in language-enabled constructs.
The following If
construct is available in my github.com/icza/gox
library with lots of other methods, being the gox.If
type.
Go allows to attach methods to any user-defined types, including primitive types such as bool
. We can create a custom type having bool
as its underlying type, and then with a simple type conversion on the condition, we have access to its methods. Methods that receive and select from the operands.
Something like this:
type If bool
func (c If) Int(a, b int) int {
if c {
return a
}
return b
}
How can we use it?
i := If(condition).Int(val1, val2) // Short variable declaration, i is of type int
|-----------| \
type conversion \---method call
For example a ternary doing max()
:
i := If(a > b).Int(a, b)
A ternary doing abs()
:
i := If(a >= 0).Int(a, -a)
This looks cool, it's simple, elegant, and efficient (it's also eligible for inlining).
One downside compared to a "real" ternary operator: it always evaluates all operands.
To achieve deferred and only-if-needed evaluation, the only option is to use functions (either declared functions or methods, or function literals), which are only called when / if needed:
func (c If) Fint(fa, fb func() int) int {
if c {
return fa()
}
return fb()
}
Using it: Let's assume we have these functions to calculate a
and b
:
func calca() int { return 3 }
func calcb() int { return 4 }
Then:
i := If(someCondition).Fint(calca, calcb)
For example, the condition being current year > 2020:
i := If(time.Now().Year() > 2020).Fint(calca, calcb)
If we want to use function literals:
i := If(time.Now().Year() > 2020).Fint(
func() int { return 3 },
func() int { return 4 },
)
Final note: if you would have functions with different signatures, you could not use them here. In that case you may use a function literal with matching signature to make them still applicable.
For example if calca()
and calcb()
would have parameters too (besides the return value):
func calca2(x int) int { return 3 }
func calcb2(x int) int { return 4 }
This is how you could use them:
i := If(time.Now().Year() > 2020).Fint(
func() int { return calca2(0) },
func() int { return calcb2(0) },
)
Try these examples on the Go Playground.
No, you can't change iPad's host file(without jailbreak), but can workaround.
Here is my scenario:
192.168.2.1
, running a web appI am going to test the web app running in my Mac via iPad, but I can't access directly to it.
The solution works for me:
Port
(mostly 8888
) and toggle Enable transparent HTTP proxying
.Now you can visit your web app in iPad.
Of course you can use other proxy tools like Squid or Varnish in Linux, or fiddler in Wondows.
If the number of fields in the CSV is constant then you could do something like this:
select a[1], a[2], a[3], a[4]
from (
select regexp_split_to_array('a,b,c,d', ',')
) as dt(a)
For example:
=> select a[1], a[2], a[3], a[4] from (select regexp_split_to_array('a,b,c,d', ',')) as dt(a);
a | a | a | a
---+---+---+---
a | b | c | d
(1 row)
If the number of fields in the CSV is not constant then you could get the maximum number of fields with something like this:
select max(array_length(regexp_split_to_array(csv, ','), 1))
from your_table
and then build the appropriate a[1], a[2], ..., a[M]
column list for your query. So if the above gave you a max of 6, you'd use this:
select a[1], a[2], a[3], a[4], a[5], a[6]
from (
select regexp_split_to_array(csv, ',')
from your_table
) as dt(a)
You could combine those two queries into a function if you wanted.
For example, give this data (that's a NULL in the last row):
=> select * from csvs;
csv
-------------
1,2,3
1,2,3,4
1,2,3,4,5,6
(4 rows)
=> select max(array_length(regexp_split_to_array(csv, ','), 1)) from csvs;
max
-----
6

Since your delimiter is a simple fixed string, you could also use string_to_array
instead of regexp_split_to_array
:
select ...
from (
select string_to_array(csv, ',')
from csvs
) as dt(a);
Thanks to Michael for the reminder about this function.
You really should redesign your database schema to avoid the CSV column if at all possible. You should be using an array column or a separate table instead.
I've recently stumbled upon the following solution to this problem:
Source: Multiple versions of Chrome
...this is registry data problem: How to do it then (this is an example for 2.0.172.39 and 3.0.197.11, I'll try it with next versions as they will come, let's assume I've started with Chrome 2):
Install Chrome 2, you'll find it
Application Data
folder, since I'm from Czech Republic and my name is Bronislav Klucka the path looks like this:C:\Documents and Settings\Bronislav Klucka\Local Settings\Data aplikací\Google\Chrome
and run Chrome
Open registry and save
[HKEY_CURRENT_USER\Software\Google\Update\Clients\{8A69D345-D564-463c-AFF1-A69D9E530F96}] [HKEY_CURRENT_USER\Software\Google\Update\ClientState\{8A69D345-D564-463c-AFF1-A69D9E530F96}]
keys, put them into one chrome2.reg file and copy this file next to
chrome.exe
(ChromeDir\Application)Rename Chrome folder to something else (e.g. Chrome2)
Install Chrome 3, it will install to Chrome folder again and run Chrome
- Save the same keys (there are changes due to different version) and save it to the
chrome3.reg
file next tochrome.exe
file of this new version againRename the folder again (e.g. Chrome3)
the result would be that there is no Chrome dir (only Chrome2 and Chrome3)
Go to the Application folder of Chrome2, create
chrome.bat
file with this content:@echo off regedit /S chrome2.reg START chrome.exe -user-data-dir="C:\Docume~1\Bronis~1\LocalS~1\Dataap~1\Google\Chrome2\User Data" rem START chrome.exe -user-data-dir="C:\Documents and Settings\Bronislav Klucka\Local Settings\Data aplikací\Google\Chrome2\User Data"
the first line is generic batch command, the second line will update registry with the content of
chrome2.reg
file, the third lines starts Chrome pointing to passed directory, the 4th line is commented and will not be run.Notice short name format passed as
-user-data-dir
parameter (the full path is at the 4th line), the problem is that Chrome using this parameter has a problem with diacritics (Czech characters)Do 7. again for Chrome 3, update paths and reg file name in bat file for Chrome 3
Try running both bat files, seems to be working, both versions of Chrome are running simultaneously.
Updating: Running "About" dialog displays correct version, but an error while checking for new one. To correct that do (I'll explain form Chrome2 folder): 1. rename Chrome2 to Chrome 2. Go to Chrome/Application folder 3. run chrome2.reg file 4. run chrome.exe (works the same for Chrome3) now the version checking works. There has been no new version of Chrome since I've find this whole solution up. But I assume that update will be downloaded to this folder so all you need to do is to update reg file after update and rename Chrome folder back to Chrome2. I'll update this post after successful Chrome update.

I think, that in this case using PYTHONPATH is a better thing, mostly because it doesn't introduce (questionable) unneccessary code.
After all, if you think of it, your user doesn't need that sys.path
thing, because your package will get installed into site-packages, because you will be using a packaging system.
If the user chooses to run from a "local copy", as you call it, then I've observed, that the usual practice is to state, that the package needs to be added to PYTHONPATH manually, if used outside the site-packages.
My favorite method for doing this is to write it out as a batch script to combine both user variables and system variables into a single backup file like so, create an environment-backup.bat
file and put in it:
@echo off
:: RegEdit can only export into a single file at a time, so create two temporary files.
regedit /e "%CD%\environment-backup1.reg" "HKEY_CURRENT_USER\Environment"
regedit /e "%CD%\environment-backup2.reg" "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Environment"
:: Concatenate into a single file and remove temporary files.
type "%CD%\environment-backup1.reg" "%CD%\environment-backup2.reg" > environment-backup.reg
del "%CD%\environment-backup1.reg"
del "%CD%\environment-backup2.reg"
This creates environment-backup.reg
which you can use to re-import existing environment variables. This will add & override new variables, but not delete existing ones :)
boolean entered = false, last;
while (( entered |= last = ( condition ) )) {
// Do while
} if ( !entered ) {
// Else
}
You'r welcome.
If you would like to execute the parent controller's parentmethod function inside a child controller, call it:
$scope.$parent.parentmethod();
You can try it over here
The function time.NewTicker
makes a channel that sends a periodic message, and provides a way to stop it. Use it something like this (untested):
ticker := time.NewTicker(5 * time.Second)
quit := make(chan struct{})
go func() {
for {
select {
case <- ticker.C:
// do stuff
case <- quit:
ticker.Stop()
return
}
}
}()
You can stop the worker by closing the quit
channel: close(quit)
.
Though I don't see much point, here it is:
for i in xrange(0, len(prices)):
exec("price%d = %s" % (i + 1, repr(prices[i])));
Do git help gitignore

Are you using the userdir mod?
In that case the thing is that PHP5 seems to be disabling running scripts from that location by default and you have to comment out the following lines:
<IfModule mod_userdir.c>
<Directory /home/*/public_html>
php_admin_flag engine Off
</Directory>
</IfModule>
in /etc/apache2/mods-enabled/php5.conf

The Node.js package is available in the LTS release and the current release. It’s your choice to select which version you want to install on the system as per your requirements.
Use Current Release: At the last update of this tutorial, Node.js 13 is the current Node.js release available.
sudo apt-get install curl
curl -sL https://deb.nodesource.com/setup_13.x | sudo -E bash -
Use LTS Release: At the last update of this tutorial, Node.js 12.x is the LTS release available.
sudo apt-get install curl
curl -sL https://deb.nodesource.com/setup_12.x | sudo -E bash -
You can successfully add Node.js PPA to the Ubuntu system. Now execute the below command to install Node.js on and Ubuntu using apt-get. This will also install NPM with Node.js. This command also installs many other dependent packages on your system.
sudo apt-get install nodejs
After installing Node.js, verify and check the installed version. You can find more details about the current version on the Node.js official website.
node -v
v13.0.1
Also, check the npm version:
npm -v

If you need digits (after separator), you can simply split number and count length second part (after point).
function countDigits(number) {
var sp = (number + '').split('.');
if (sp[1] !== undefined) {
return sp[1].length;
} else {
return 0;
}
}
You should use profiles.
<profiles>
<profile>
<id>otherOutputDir</id>
<build>
<directory>yourDirectory</directory>
</build>
</profile>
</profiles>
And start maven with your profile
mvn compile -PotherOutputDir
If you really want to define your directory from the command line you could do something like this (NOT recommended at all) :
<properties>
<buildDirectory>${project.basedir}/target</buildDirectory>
</properties>
<build>
<directory>${buildDirectory}</directory>
</build>
And compile like this :
mvn compile -DbuildDirectory=test
That's because you can't change the target directory by using -Dproject.build.directory
How to include the jars of your project into your runnable jar:
I'm using Eclipse Version: 3.7.2 running on Ubuntu 12.10. I'll also show you how to make the build.xml
so you can do the ant jar
from command line and create your jar with other imported jars extracted into it.
Basically you ask Eclipse to construct the build.xml that imports your libraries into your jar for you.
Fire up Eclipse and make a new Java project, make a new package 'mypackage', add your main class: Runner
Put this code in there.
Now include the mysql-connector-java-5.1.28-bin.jar
from Oracle which enables us to write Java to connect to the MySQL database. Do this by right clicking the project -> properties -> java build path -> Add External Jar -> pick mysql-connector-java-5.1.28-bin.jar.
Run the program within eclipse, it should run, and tell you that the username/password is invalid which means Eclipse is properly configured with the jar.
In Eclipse go to File
-> Export
-> Java
-> Runnable Jar File
. You will see this dialog:
Make sure to set up the 'save as ant script' checkbox. That is what makes it so you can use the commandline to do an ant jar
later.
Then go to the terminal and look at the ant script:
So you see, I ran the jar and it didn't error out because it found the included mysql-connector-java-5.1.28-bin.jar
embedded inside Hello.jar
.
Look inside Hello.jar: vi Hello.jar
and you will see many references to com/mysql/jdbc/stuff.class
To do ant jar
on the commandline to do all this automatically: Rename buildant.xml
to build.xml
, and change the target name from create_run_jar
to jar
.
Then, from within MyProject
you type ant jar
and boom. You've got your jar inside MyProject. And you can invoke it using java -jar Hello.jar
and it all works.
If you call this function then you easily get the client's IP address. I have already used this in my existing project:
public function getUserIpAddr(){
$ipaddress = '';
if (isset($_SERVER['HTTP_CLIENT_IP']))
$ipaddress = $_SERVER['HTTP_CLIENT_IP'];
else if(isset($_SERVER['HTTP_X_FORWARDED_FOR']))
$ipaddress = $_SERVER['HTTP_X_FORWARDED_FOR'];
else if(isset($_SERVER['HTTP_X_FORWARDED']))
$ipaddress = $_SERVER['HTTP_X_FORWARDED'];
else if(isset($_SERVER['HTTP_FORWARDED_FOR']))
$ipaddress = $_SERVER['HTTP_FORWARDED_FOR'];
else if(isset($_SERVER['HTTP_FORWARDED']))
$ipaddress = $_SERVER['HTTP_FORWARDED'];
else if(isset($_SERVER['REMOTE_ADDR']))
$ipaddress = $_SERVER['REMOTE_ADDR'];
else
$ipaddress = 'UNKNOWN';
return $ipaddress;
}
Getting EXIF data from a JPEG image involves:
use the JavaScript Date()
object. There are a number of ways to get the time, date, timestamps, etc from the object. (Reference)
function myFunction() {
var d = new Date();
var timeStamp = d.getTime(); // Number of ms since Jan 1, 1970
// OR:
var currentTime = d.toLocaleTimeString(); // "12:35 PM", for instance
}
select group_id,
listagg(name, ',') within group (order by name) as names
over (partition by group_id)
from demotable
group by group_id
If you take a look at @types/node-fetch you will see the body definition
export class Body {
bodyUsed: boolean;
body: NodeJS.ReadableStream;
json(): Promise<any>;
json<T>(): Promise<T>;
text(): Promise<string>;
buffer(): Promise<Buffer>;
}
That means that you could use generics in order to achieve what you want. I didn't test this code, but it would looks something like this:
import { Actor } from './models/actor';
fetch(`http://swapi.co/api/people/1/`)
.then(res => res.json<Actor>())
.then(res => {
let b:Actor = res;
});

Yes you can do it yourself. It is just a matter of grabbing the sources of the page and parsing them the way you want.
There are various possibilities. A good combo is using python-requests (built on top of urllib2, it is urllib.request
in Python3) and BeautifulSoup4, which has its methods to select elements and also permits CSS selectors:
import requests
from BeautifulSoup4 import BeautifulSoup as bs
request = requests.get("http://foo.bar")
soup = bs(request.text)
some_elements = soup.find_all("div", class_="myCssClass")
Some will prefer xpath parsing or jquery-like pyquery, lxml or something else.
When the data you want is produced by some JavaScript, the above won't work. You either need python-ghost or Selenium. I prefer the latter combined with PhantomJS, much lighter and simpler to install, and easy to use:
from selenium import webdriver
client = webdriver.PhantomJS()
client.get("http://foo")
soup = bs(client.page_source)
I would advice to start your own solution. You'll understand Scrapy's benefits doing so.

You can import react-native-elements and use the font-awesome icons to your react native app
Install
npm install --save react-native-elements
then import that where you want to use icons
import { Icon } from 'react-native-elements'
Use it like
render() {
return(
<Icon
reverse
name='ios-american-football'
type='ionicon'
color='#517fa4'
/>
);
}
One way of doing it is to use the ClientScriptManager
:
Page.ClientScript.RegisterStartupScript(
GetType(),
"MyKey",
"Myfunction();",
true);
I had this problem with only with redirectMode="ResponseRewrite"
(redirectMode="ResponseRedirect"
worked fine) and none of the above solutions helped my resolve the issue. However, once I changed the server's application pool's "Managed Pipeline Mode" from "Classic" to "Integrated" the custom error page appeared as expected.
An understanding of the Iterator pattern will be helpful for you. I recommend reading the same.
At a high level the iterator pattern can be used to provide a standard way of iterating through collections of any type. We have 3 participants in the iterator pattern, the actual collection (client), the aggregator and the iterator. The aggregate is an interface/abstract class that has a method that returns an iterator. Iterator is an interface/abstract class that has methods allowing us to iterate through a collection.
In order to implement the pattern we first need to implement an iterator to produce a concrete that can iterate over the concerned collection (client) Then the collection (client) implements the aggregator to return an instance of the above iterator.
So basically in c#, IEnumerable is the abstract aggregate and IEnumerator is the abstract Iterator. IEnumerable has a single method GetEnumerator that is responsible for creating an instance of IEnumerator of the desired type. Collections like Lists implement the IEnumerable.
Example.
Lets suppose that we have a method getPermutations(inputString)
that returns all the permutations of a string and that the method returns an instance of IEnumerable<string>
In order to count the number of permutations we could do something like the below.
int count = 0;
var permutations = perm.getPermutations(inputString);
foreach (string permutation in permutations)
{
count++;
}
The c# compiler more or less converts the above to
using (var permutationIterator = perm.getPermutations(input).GetEnumerator())
{
while (permutationIterator.MoveNext())
{
count++;
}
}
If you have any questions please don't hesitate to ask.
You can use this in python3:
exec(open(filename).read())
I have implemented callback/delegate support in Java using reflection. Details and working source are available on my website.
How It Works
We have a principle class named Callback with a nested class named WithParms. The API which needs the callback will take a Callback object as a parameter and, if neccessary, create a Callback.WithParms as a method variable. Since a great many of the applications of this object will be recursive, this works very cleanly.
With performance still a high priority to me, I didn't want to be required to create a throwaway object array to hold the parameters for every invocation - after all in a large data structure there could be thousands of elements, and in a message processing scenario we could end up processing thousands of data structures a second.
In order to be threadsafe the parameter array needs to exist uniquely for each invocation of the API method, and for efficiency the same one should be used for every invocation of the callback; I needed a second object which would be cheap to create in order to bind the callback with a parameter array for invocation. But, in some scenarios, the invoker would already have a the parameter array for other reasons. For these two reasons, the parameter array did not belong in the Callback object. Also the choice of invocation (passing the parameters as an array or as individual objects) belongs in the hands of the API using the callback enabling it to use whichever invocation is best suited to it's inner workings.
The WithParms nested class, then, is optional and serves two purposes, it contains the parameter object array needed for the callback invocations, and it provides 10 overloaded invoke() methods (with from 1 to 10 parameters) which load the parameter array and then invoke the callback target.

The most upvoted answer is not implementing a real slide in/out (or down/up), as:
translateY(-100%)
and then suddenly disappears, causing another glitch on the elements below it.You can implement a slide in and slide out like so:
my-component.ts
import { animate, style, transition, trigger } from '@angular/animations';
@Component({
...
animations: [
trigger('slideDownUp', [
transition(':enter', [style({ height: 0 }), animate(500)]),
transition(':leave', [animate(500, style({ height: 0 }))]),
]),
],
})
my-component.html
<div @slideDownUp *ngIf="isShowing" class="box">
I am the content of the div!
</div>
my-component.scss
.box {
overflow: hidden;
}
<p><b> BOLD TEXT </b> not in bold </p>;
Include the text you want to be in bold between <b>...</b>
Try this code
HashMap<String, String> map = new HashMap<String, String>();
map.put("EmpID", EmpID);
map.put("UnChecked", "1");
Olof's answer is good, but it needs one more thing before it's perfect. In the comments below his answer, dacwe (correctly) points out that his implementation violates the Compare/Equals contract for Sets. If you try to call contains or remove on an entry that's clearly in the set, the set won't recognize it because of the code that allows entries with equal values to be placed in the set. So, in order to fix this, we need to test for equality between the keys:
static <K,V extends Comparable<? super V>> SortedSet<Map.Entry<K,V>> entriesSortedByValues(Map<K,V> map) {
SortedSet<Map.Entry<K,V>> sortedEntries = new TreeSet<Map.Entry<K,V>>(
new Comparator<Map.Entry<K,V>>() {
@Override public int compare(Map.Entry<K,V> e1, Map.Entry<K,V> e2) {
int res = e1.getValue().compareTo(e2.getValue());
if (e1.getKey().equals(e2.getKey())) {
return res; // Code will now handle equality properly
} else {
return res != 0 ? res : 1; // While still adding all entries
}
}
}
);
sortedEntries.addAll(map.entrySet());
return sortedEntries;
}
"Note that the ordering maintained by a sorted set (whether or not an explicit comparator is provided) must be consistent with equals if the sorted set is to correctly implement the Set interface... the Set interface is defined in terms of the equals operation, but a sorted set performs all element comparisons using its compareTo (or compare) method, so two elements that are deemed equal by this method are, from the standpoint of the sorted set, equal." (http://docs.oracle.com/javase/6/docs/api/java/util/SortedSet.html)
Since we originally overlooked equality in order to force the set to add equal valued entries, now we have to test for equality in the keys in order for the set to actually return the entry you're looking for. This is kinda messy and definitely not how sets were intended to be used - but it works.
If you have access to a unix server that's always up, you can set a cron job to GET

Gradle looks for gradle.properties
files in these places:
GRADLE_USER_HOME
environment variable, which if not set defaults to USER_HOME/.gradle

.I used to use Firebug, until Internet Explorer 8 came out. I'm not a huge fan of Internet Explorer, but after spending some time with the built-in developer tools, which includes a really nice debugger, it seems pointless to use anything else. I have to tip my hat to Microsoft they did a fantastic job on this tool.
You want to iterate backwards through using a counter instead of foreach. If you iterate forwards you have to adjust the counter as you delete items.
for(int i=listBox1.Items.Count - 1; i > -1; i--) {
{
if(listBox1.Items[i].Contains("OBJECT"))
{
listBox1.Items.RemoveAt(i);
}
}
So this has happened a couple of times just recently. As a .Net dev, using VisualStudio I changed my build name from SomeThing
to Something
as the DLL name but this does not change the .csproj file which stays SomeThing.csproj
The Dockerfile uses linux case-sensitive filenames, so the newly autogenerated Dockerfile was trying to copy Something.csproj
which it couldn't find. So manually renaming that file (making it lowercase) got it all working
But...here's a cautionary warning. This filename change on my Windows laptop does not get picked up by Git so the repo source was still SomeThing.csproj
on the repo and during the CI/CD process, the Docker build failed for the same reasons...
I had to change the filename directly as a commit on the repo....nasty little workaround but got me going
tl;dr If on Windows O/S check for filename case sensitivity and be aware local file renames do not get picked up as Git change so make sure your repo is also modified if using CI/CD
If you write only equal condition just: Select Case columns1 When 0 then 'Value1' when 1 then 'Value2' else 'Unknown' End
If you want to write greater , Less then or equal you must do like this: Select Case When [ColumnsName] >0 then 'value1' When [ColumnsName]=0 Or [ColumnsName]<0 then 'value2' Else 'Unkownvalue' End

Thanks Mr.Buntha Khin
For List<List<List<x>>>
and so on, use
list.SelectMany(x => x.SelectMany(y => y)).ToList();
This has been posted in a comment, but it does deserves a separate reply in my opinion.
You can try it out http://api.jquery.com/mouseover/ on the jQuery doc page. It's a nice little, interactive demo that makes it very clear and you can actually see for yourself.
In short, you'll notice that a mouse over event occurs on an element when you are over it - coming from either its child OR parent element, but a mouse enter event only occurs when the mouse moves from the parent element to the element.
Normally you want to perform this check atomically with using the result, so stat()
is useless. Instead, open()
the file read-only first and use fstat()
. If it's a directory, you can then use fdopendir()
to read it. Or you can try opening it for writing to begin with, and the open will fail if it's a directory. Some systems (POSIX 2008, Linux) also have an O_DIRECTORY
extension to open
which makes the call fail if the name is not a directory.
Your method with opendir()
is also good if you want a directory, but you should not close it afterwards; you should go ahead and use it.
WARNING! THIS WILL DELETE THE ENTIRE GIT HISTORY FOR YOUR SUBMODULE. ONLY DO THIS IF YOU CREATED THE SUBMODULE BY ACCIDENT. CERTAINLY NOT WHAT YOU WANT TO DO IN MOST CASES.
I think you have to go inside week1 folder and delete the .git folder:
sudo rm -Rf .git
then go back to top level folder and do:
git add .
then do a commit and push the code.
You can create an html page with a form, having method="post" and action="yourdesiredurl" and open it with your browser.
As an alternative, there are some browser plugins for developers that allow you to do that, like Web Developer Toolbar for Firefox
a_list = []
b_list = []
for i in range(1,100):
a_list.append(random.randint(1,100))
for i in range(1,100):
a_list.append(random.randint(101,200))
[sum(x) for x in zip(a_list , b_list )]
You shall proceed with ent.delete(0,"end")
instead of using 'END', use 'end' inside quotation.
secret = randrange(1,100)
print(secret)
def res(real, secret):
if secret==eval(real):
showinfo(message='that is right!')
real.delete(0, END)
def guess():
ge = Tk()
ge.title('guessing game')
Label(ge, text="what is your guess:").pack(side=TOP)
ent = Entry(ge)
ent.pack(side=TOP)
btn=Button(ge, text="Enter", command=lambda: res(ent.get(),secret))
btn.pack(side=LEFT)
ge.mainloop()
This shall solve your problem
Alternative "fake" solution if you have a list with options similar in text length (page select for example):
padding-left: calc(50% - 1em);
This works in Chrome, Firefox and Edge. The trick is here to push the text from the left to the center, then substract the half of length in px, em or whatever of the option text.
Best solution IMO (in 2017) is still replacing the select via JS and build your own fake select-box with divs or whatever and bind click events on it for cross-browser support.
As of ES 7, mapping types have been removed. You can read more details here
If you are using Ruby On Rails this means that you may need to remove document_type
from your model or concern.
As an alternative to mapping types one solution is to use an index per document type.
Before:
module Searchable
extend ActiveSupport::Concern
included do
include Elasticsearch::Model
include Elasticsearch::Model::Callbacks
index_name [Rails.env, Rails.application.class.module_parent_name.underscore].join('_')
document_type self.name.downcase
end
end
After:
module Searchable
extend ActiveSupport::Concern
included do
include Elasticsearch::Model
include Elasticsearch::Model::Callbacks
index_name [Rails.env, Rails.application.class.module_parent_name.underscore, self.name.downcase].join('_')
end
end

You can use tail
:
$ foo="1234567890"
$ echo -n $foo | tail -c 3
890
A somewhat roundabout way to get the last three characters would be to say:
echo $foo | rev | cut -c1-3 | rev
If you are using posix sed
Selection for any case for a pattern (converting the searched pattern with this sed than use the converted pattern in you wanted command using regex:
echo "${MyOrgPattern} | sed "s/[aA]/[aA]/g;s/[bB]/[bB]/g;s/[cC]/[cC]/g;s/[dD]/[dD]/g;s/[eE]/[eE]/g;s/[fF]/[fF]/g;s/[gG]/[gG]/g;s/[hH]/[hH]/g;s/[iI]/[iI]/g;s/[jJ]/[jJ]/g;s/[kK]/[kK]/g;s/[lL]/[lL]/g;s/[mM]/[mM]/g;s/[nN]/[nN]/g;s/[oO]/[oO]/g;s/[pP]/[pP]/g;s/[qQ]/[qQ]/g;s/[rR]/[rR]/g;s/[sS]/[sS]/g;s/[tT]/[tT]/g;s/[uU]/[uU]/g;s/[vV]/[vV]/g;s/[wW]/[wW]/g;s/[xX]/[xX]/g;s/[yY]/[yY]/g;s/[zZ]/[zZ]/g" | read -c MyNewPattern
YourInputStreamCommand | egrep "${MyNewPattern}"
convert in lower case
sed "s/[aA]/a/g;s/[bB]/b/g;s/[cC]/c/g;s/[dD]/d/g;s/[eE]/e/g;s/[fF]/f/g;s/[gG]/g/g;s/[hH]/h/g;s/[iI]/i/g;s/j/[jJ]/g;s/[kK]/k/g;s/[lL]/l/g;s/[mM]/m/g;s/[nN]/n/g;s/[oO]/o/g;s/[pP]/p/g;s/[qQ]/q/g;s/[rR]/r/g;s/[sS]/s/g;s/[tT]/t/g;s/[uU]/u/g;s/[vV]/v/g;s/[wW]/w/g;s/[xX]/x/g;s/[yY]/y/g;s/[zZ]/z/g"
same for uppercase replace lower letter between // by upper equivalent in the sed
Have fun
I did this for an array of objects. Its basically creating new keys in the same array and unsetting the old keys.
public function transform($key, $results)
{
foreach($results as $k=>$result)
{
if( property_exists($result, $key) )
{
$results[$result->$key] = $result;
unset($results[$k]);
}
}
return $results;
}
A somewhat common use case for creating an empty file is to trigger something else happening in a different process in the absence of more sophisticated in process communication. In this case, it can help to have the file creation be atomic from the outside world's point of view (particularly if the thing being triggered is going to delete the file to "consume" the trigger).
So it can help to create a junk name (Guid.NewGuid.ToString()) in the same directory as the file you want to create, and then do a File.Move from the temporary name to your desired name. Otherwise triggered code which checks for file existence and then deletes the trigger may run into race conditions where the file is deleted before it is fully closed out.
Having the temp file in the same directory (and file system) gives you the atomicity you may want. This gives something like.
public void CreateEmptyFile(string path)
{
string tempFilePath = Path.Combine(Path.GetDirectoryName(path),
Guid.NewGuid.ToString());
using (File.Create(tempFilePath)) {}
File.Move(tempFilePath, path);
}
Suppose you have a project called "TestProject" on Eclipse and your workspace folder is located at E:/eclipse/workspace. When you build an Eclipse project, your classpath is then e:/eclipse/workspace/TestProject
. When you try to read "staedteliste.txt", you're trying to access the file at e:/eclipse/workspace/TestProject/staedteliste.txt
.
If you want to have a separate folder for your project, then create the Files folder under TestProject and then access the file with (the relative path) /Files/staedteliste.txt
. If you put the file under the src folder, then you have to access it using /src/staedteliste.txt
. A Files folder inside the src folder would be /src/Files/staedteliste.txt
Instead of using the the relative path you can use the absolute one by adding e:/eclipse/workspace/
at the beginning, but using the relative path is better because you can move the project without worrying about refactoring as long as the project folder structure is the same.
I think you are casting in the wrong direction though... if the method returns a list of TestA
objects, then it really isn't safe to cast them to TestB
.
Basically you are asking the compiler to let you perform TestB
operations on a type TestA
that does not support them.
I believe this happens because you use the different versions of the same class on client and server. It can be different data fields or methods
Use:
$('#example').dataTable({
aLengthMenu: [
[25, 50, 100, 200, -1],
[25, 50, 100, 200, "All"]
],
iDisplayLength: -1
});
Or if using 1.10+
$('#example').dataTable({
paging: false
});
The option you should use is iDisplayLength:
$('#adminProducts').dataTable({
'iDisplayLength': 100
});
$('#table').DataTable({
"lengthMenu": [ [5, 10, 25, 50, -1], [5, 10, 25, 50, "All"] ]
});
It will Load by default all entries.
$('#example').dataTable({
aLengthMenu: [
[25, 50, 100, 200, -1],
[25, 50, 100, 200, "All"]
],
iDisplayLength: -1
});
Or if using 1.10+
$('#example').dataTable({
paging: false
});
If you want to load by default 25 not all do this.
$('#example').dataTable({
aLengthMenu: [
[25, 50, 100, 200, -1],
[25, 50, 100, 200, "All"]
],
});

getDay()
returns the day of the week. To get the date, use date.getDate()
. getMonth()
retrieves the month, but month is zero based, so using getMonth()+1
should give you the right month. Time value seems to be ok here, albeit the hour is 23 here (GMT+1). If you want universal values, add UTC
to the methods (e.g. date.getUTCFullYear()
, date.getUTCHours()
)
var timestamp = 1301090400,
date = new Date(timestamp * 1000),
datevalues = [
date.getFullYear(),
date.getMonth()+1,
date.getDate(),
date.getHours(),
date.getMinutes(),
date.getSeconds(),
];
alert(datevalues); //=> [2011, 3, 25, 23, 0, 0]

I needed to do both:
You can call a reset function before appending. Something like this:
function resetNewReviewBoardForm() {
$("#Description").val('');
$("#PersonName").text('');
$("#members").empty(); //this one what worked in my case
$("#EmailNotification").val('False');
}
You should target the smallest, not the largest, supported pixel resolution by the devices your app can run on.
Say if there's an actual Mac computer that can run OS X 10.9 and has a native screen resolution of only 1280x720 then that's the resolution you should focus on. Any higher and your game won't correctly run on this device and you could as well remove that device from your supported devices list.
You can rely on upscaling to match larger screen sizes, but you can't rely on downscaling to preserve possibly important image details such as text or smaller game objects.
The next most important step is to pick a fitting aspect ratio, be it 4:3 or 16:9 or 16:10, that ideally is the native aspect ratio on most of the supported devices. Make sure your game only scales to fit on devices with a different aspect ratio.
You could scale to fill but then you must ensure that on all devices the cropped areas will not negatively impact gameplay or the use of the app in general (ie text or buttons outside the visible screen area). This will be harder to test as you'd actually have to have one of those devices or create a custom build that crops the view accordingly.
Alternatively you can design multiple versions of your game for specific and very common screen resolutions to provide the best game experience from 13" through 27" displays. Optimized designs for iMac (desktop) and a Macbook (notebook) devices make the most sense, it'll be harder to justify making optimized versions for 13" and 15" plus 21" and 27" screens.
But of course this depends a lot on the game. For example a tile-based world game could simply provide a larger viewing area onto the world on larger screen resolutions rather than scaling the view up. Provided that this does not alter gameplay, like giving the player an unfair advantage (specifically in multiplayer).
You should provide @2x images for the Retina Macbook Pro and future Retina Macs.
Your code is working just fine, you have to declare javscript method before DOM ready.
Just my 2 cents. I would create a solution which records exactly what changed, very similar to transient's solution.
My ChangesTable would simple be:
DateTime | WhoChanged | TableName | Action | ID |FieldName | OldValue
1) When an entire row is changed in the main table, lots of entries will go into this table, BUT that is very unlikely, so not a big problem (people are usually only changing one thing) 2) OldVaue (and NewValue if you want) have to be some sort of epic "anytype" since it could be any data, there might be a way to do this with RAW types or just using JSON strings to convert in and out.
Minimum data usage, stores everything you need and can be used for all tables at once. I'm researching this myself right now, but this might end up being the way I go.
For Create and Delete, just the row ID, no fields needed. On delete a flag on the main table (active?) would be good.
from sys import version_info, api_version, version, hexversion
print(f"sys.version: {version}")
print(f"sys.api_version: {api_version}")
print(f"sys.version_info: {version_info}")
print(f"sys.hexversion: {hexversion}")
output
sys.version: 3.6.5 (v3.6.5:f59c0932b4, Mar 28 2018, 17:00:18) [MSC v.1900 64 bit (AMD64)] sys.api_version: 1013 sys.version_info: sys.version_info(major=3, minor=6, micro=5, releaselevel='final', serial=0) sys.hexversion: 50726384
Looks like one way to handle this in Rails 2.3 (since update_without_callbacks is gone, etc.), would be to use update_all, which is one of the methods that skips callbacks as per section 12 of the Rails Guide to validations and callbacks.
Also, note that if you are doing something in your after_ callback, that does a calculation based on many association (i.e. a has_many assoc, where you also do accepts_nested_attributes_for), you will need to reload the association, in case as part of the save, one of its members was deleted.
If you are using Clojure, you have another option:
(defn map-entry
[k v]
(clojure.lang.MapEntry/create k v))
I resolved the problem by following these steps:
Select the project - Right click - java build path.
In source tab - you change the src
to src/main/java
.
Eclipse will reorder all the project.
I have a perfect solution for this problem. After doing following simple steps you will be able to Import your source codes in Eclipse!
First of all, the reason why you can not Import your project into Eclipse workstation is that you do not have .project and .classpath file.
Now we know why this happens, so all we need to do is to create .project and .classpath file inside the project file. Here is how you do it:
First create .classpath file:
copy paste following codes and save it:
<?xml version="1.0" encoding="UTF-8"?>
<classpath>
<classpathentry kind="src" path="src"/>
<classpathentry kind="con" path="org.eclipse.jdt.launching.JRE_CONTAINER"/>
<classpathentry kind="output" path="bin"/>
</classpath>
Then create .project file:
copy paste following codes:
<?xml version="1.0" encoding="UTF-8"?>
<projectDescription>
<name>HereIsTheProjectName</name>
<comment></comment>
<projects>
</projects>
<buildSpec>
<buildCommand>
<name>org.eclipse.jdt.core.javabuilder</name>
<arguments>
</arguments>
</buildCommand>
</buildSpec>
<natures>
<nature>org.eclipse.jdt.core.javanature</nature>
</natures>
</projectDescription>
you have to change the name field to your project name. you can do this in line 3 by changing HereIsTheProjectName to your own project name. then save it.
That is all, Enjoy!!
It is to mark the parameter as optional.
This way will work for sure, I hope it helps:
CREATE TABLE fruits(
id SERIAL PRIMARY KEY,
name VARCHAR NOT NULL
);
INSERT INTO fruits(id,name) VALUES(DEFAULT,'apple');
or
INSERT INTO fruits VALUES(DEFAULT,'apple');
You can check this the details in the next link: http://www.postgresqltutorial.com/postgresql-serial/
In at least Postgres, you can use the alias name in the group by clause:
SELECT itemName as ItemName1, substring(itemName, 1,1) as FirstLetter, Count(itemName) FROM table1 GROUP BY ItemName1, FirstLetter;
I wouldn't recommend renaming an alias as a change in capitalization, that causes confusion.
By creating the increment table you should be aware not to delete inserted rows. reason for this is to avoid storing large dumb data in db with ID-s in it. Otherwise in case of mysql restart it would get max existing row and continue increment from that point as mention in documentation http://dev.mysql.com/doc/refman/5.0/en/innodb-auto-increment-handling.html
It depends how much you want to customize the alert dialog. I have different steps in order to customize the alert dialog. Please visit: https://stackoverflow.com/a/33439849/5475941
public void schedule(TimerTask task,long delay)
Schedules the specified task for execution after the specified delay.
you want:
public void schedule(TimerTask task, long delay, long period)
Schedules the specified task for repeated fixed-delay execution, beginning after the specified delay. Subsequent executions take place at approximately regular intervals separated by the specified period.
You can use regular expressions for extracting the number from string. Lets check it. Suppose this is the string mixing text and numbers 'stack12345overflow569'. This one should work:
select regexp_replace('stack12345overflow569', '[[:alpha:]]|_') as numbers from dual;
which will return "12345569".
also you can use this one:
select regexp_replace('stack12345overflow569', '[^0-9]', '') as numbers,
regexp_replace('Stack12345OverFlow569', '[^a-z and ^A-Z]', '') as characters
from dual
which will return "12345569" for numbers and "StackOverFlow" for characters.

What I did was to create a canvas element that I then position in front of the image map. Then, whenever an area is moused-over, I call a func that gets the coord string for that shape and the shape-type. If it's a poly I use the coords to draw an outline on the canvas. If it's a rect I draw a rect outline. You could easily add code to deal with circles.
You could also set the opacity of the canvas to less than 100% before filling the poly/rect/circle. You could also change the reliance on a global for the canvas's context - this would mean you could deal with more than 1 image-map on the same page.

You can try this modal:https://github.com/xue2han/react-dynamic-modal It is stateless and can be rendered only when needed.So it is very easy to use.Just like this:
class MyModal extends Component{
render(){
const { text } = this.props;
return (
<Modal
onRequestClose={this.props.onRequestClose}
openTimeoutMS={150}
closeTimeoutMS={150}
style={customStyle}>
<h1>What you input : {text}</h1>
<button onClick={ModalManager.close}>Close Modal</button>
</Modal>
);
}
}
class App extends Component{
openModal(){
const text = this.refs.input.value;
ModalManager.open(<MyModal text={text} onRequestClose={() => true}/>);
}
render(){
return (
<div>
<div><input type="text" placeholder="input something" ref="input" /></div>
<div><button type="button" onClick={this.openModal.bind(this)}>Open Modal </button> </div>
</div>
);
}
}
ReactDOM.render(<App />,document.getElementById('main'));
This iterator form is 10-15% faster than using integer indexing:
# python2 only
if str is bytes:
from itertools import izip as zip
def is_sorted(l):
return all(a <= b for a, b in zip(l, l[1:]))
toLocaleString is good, but doesn't work on all browsers. I usually use currencyFormatter.js (https://osrec.github.io/currencyFormatter.js/). It's pretty lightweight, and contains all the currency and locale definitions right out of the box. It's also good at formatting unusually formatted currencies, such as the INR (which groups numbers in lakhs and crores etc). Also no dependencies!
OSREC.CurrencyFormatter.format(2534234, { currency: 'INR' });
// Returns ? 25,34,234.00
OSREC.CurrencyFormatter.format(2534234, { currency: 'EUR' });
// Returns 2.534.234,00 €
OSREC.CurrencyFormatter.format(2534234, { currency: 'EUR', locale: 'fr' });
// Returns 2 534 234,00 €
You can get the values for the width and height of the browser using the following:
$(window).height();
$(window).width();
To get notified when the browser is resized, use this bind callback:
$(window).resize(function() {
// Do something
});
Proxies can make this a little tricky, make sure to check out ProxyFix (Flask docs) if you are using one. Take a look at request.environ
in your particular environment. With nginx I will sometimes do something like this:
from flask import request
request.environ.get('HTTP_X_REAL_IP', request.remote_addr)
When proxies, such as nginx, forward addresses, they typically include the original IP somewhere in the request headers.
Update See the flask-security implementation. Again, review the documentation about ProxyFix before implementing. Your solution may vary based on your particular environment.
This worked for me:
It starts showing compilation errors in the code.
Have you looked into the BluetoothAdapter
Android class? You set up one device as a server and the other as a client. It may be possible (although I haven't looked into it myself) to connect multiple clients to the server.
I have had success connecting a BlueTooth audio device to a phone while it also had this BluetoothAdapter
connection to another phone, but I haven't tried with three phones. At least this tells me that the Bluetooth radio can tolerate multiple simultaneous connections :)
With a project previously created in Xcode3, I see an intermediate directory under build/
called Foo.build
where Foo
is my project's name, and then in that are the directories you'd expect (Debug-iphonesimulator, Release-iphoneos, etc, assuming you've done a build of that type) containing the object files and products.
Now, I suspect that if you start a new project in Xcode4, the default location is under DerivedData, but if you open an Xcode3 project in Xcode4, then Xcode4 uses the build/ directory (as described above). So, there are several correct answers. :-) Under the File menu, Project Settings, you can see you can customize how XCode works in this regard as much or as little as you like.
Note that you can build your own cross-platform library in python using conditional imports. e.g.
import platform
if platform.system() == 'Linux':
import LinuxMac
mac_address = LinuxMac.get_mac_address()
elif platform.system() == 'Windows':
# etc
This will allow you to use os.system calls or platform-specific libraries.
I am running node.js on Windows with npm. The trick is simply use cygwin. I followed the howto under https://github.com/joyent/node/wiki/Building-node.js-on-Cygwin-(Windows) . But make sure that you use version 0.4.11 of nodejs or npm will fail!
It isn't valid to have the same ID twice, that's why #name
only finds the first one.
You can try:
$("#form2 input").val('Hello World!');
Or,
$("#form2 input[name=name]").val('Hello World!');
If you're stuck with an invalid page and want to select all #name
s, you can use the attribute selector on the id:
$("input[id=name]").val('Hello World!');
This snippet works in IE7 at least
<!DOCTYPE html>
<html>
<head>
<meta charset=utf-8 />
<title>Test</title>
<style>
#foo {
position: fixed;
bottom: 0;
right: 0;
}
</style>
</head>
<body>
<div id="foo">Hello World</div>
</body>
</html>
Add to your settings.py
:
LOGGING = {
'version': 1,
'disable_existing_loggers': False,
'handlers': {
'file': {
'level': 'DEBUG',
'class': 'logging.FileHandler',
'filename': 'debug.log',
},
},
'loggers': {
'django': {
'handlers': ['file'],
'level': 'DEBUG',
'propagate': True,
},
},
}
And it will create a file called debug.log
in the root of your.

I prefer to use Vanilla JS
let chatWrapper = document.querySelector('#chat-messages');
chatWrapper.scrollTo(0, chatWrapper.offsetHeight );
where element.scrollTo(x-coord, y-coord)
Add a class .disabled
and use this CSS:
?.disabled {border: 1px solid #999; color: #333; opacity: 0.5;}
.disabled option {color: #000; opacity: 1;}?
I am the creator of PowerMock so obviously I must recommend that! :-)
PowerMock extends both EasyMock and Mockito with the ability to mock static methods, final and even private methods. The EasyMock support is complete, but the Mockito plugin needs some more work. We are planning to add JMock support as well.
PowerMock is not intended to replace other frameworks, rather it can be used in the tricky situations when other frameworks does't allow mocking. PowerMock also contains other useful features such as suppressing static initializers and constructors.
The most important difference is that robocopy
will (usually) retry when an error occurs, while xcopy
will not. In most cases, that makes robocopy
far more suitable for use in a script.
Addendum: for completeness, there is one known edge case issue with robocopy; it may silently fail to copy files or directories whose names contain invalid UTF-16 sequences. If that's a problem for you, you may need to look at third-party tools, or write your own.
Because not all variables are of a serializable nature.
So if the Object can exists on memory but not on disk, then the Object can't be serializable, because the machine can't restore the memory map when deserialization.
Fro example, you can't serialize a Stream
object.
You can not serialize a Connection
object, because it's state also dependent on the remote site.
In UWP:
await Launcher.LaunchUriAsync(new Uri("http://google.com"));
It is 2019, and here is what is working -
despite advice here and there, what I found on the internet halfway documented is using setuptools_scm
, passed as options to setuptools.setup
. This will include any data files that are versioned on your VCS, be it git or any other, to the wheel package, and will make "pip install" from the git repository to bring those files along.
So, I just added these two lines to the setup call on "setup.py". No extra installs or import required:
setup_requires=['setuptools_scm'],
include_package_data=True,
No need to manually list package_data, or in a MANIFEST.in file - if it is versioned, it is included in the package. The docs on "setuptools_scm" put emphasis on creating a version number from the commit position, and disregard the really important part of adding the data files. (I can't care less if my intermediate wheel file is named "*0.2.2.dev45+g3495a1f" or will use the hardcoded version number "0.3.0dev0" I've typed in - but leaving crucial files for the program to work behind is somewhat important)
For this, I prefer to keep a correct HTML semantic, and to use a CSS simple as possible.
Something like this would do the job :
label{
display: block;
float: left;
width : 120px;
}
One drawback however : you might have to pick the right label width for each form, and this is not easy if your labels can be dynamic (I18N labels for instance).
