Improved Lukas Knuth's version:
public class TweakedWebView extends WebView {
private ZoomButtonsController zoomButtons;
public TweakedWebView(Context context) {
super(context);
init();
}
public TweakedWebView(Context context, AttributeSet attrs) {
super(context, attrs);
init();
}
public TweakedWebView(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
init();
}
private void init() {
getSettings().setBuiltInZoomControls(true);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) {
getSettings().setDisplayZoomControls(false);
} else {
try {
Method method = getClass()
.getMethod("getZoomButtonsController");
zoomButtons = (ZoomButtonsController) method.invoke(this);
} catch (Exception e) {
// pass
}
}
}
@Override
public boolean onTouchEvent(MotionEvent ev) {
boolean result = super.onTouchEvent(ev);
if (zoomButtons != null) {
zoomButtons.setVisible(false);
zoomButtons.getZoomControls().setVisibility(View.GONE);
}
return result;
}
}
As an alternative, if you put a space between the date and time, DateTime.Parse
will recognize the format for you. That's about as simple as you can get it. (If ParseExact
was still not being recognized)
There are a number of ways to do this:
onerror
in an img
, like <img src="http://www.example.com/singlepixel.gif" onerror="alert('Connection dead');" />
.This method could also fail if the source image is moved / renamed, and would generally be an inferior choice to the ajax option.
So there are several different ways to try and detect this, none perfect, but in the absence of the ability to jump out of the browser sandbox and access the user's net connection status directly, they seem to be the best options.
Handling events with React elements is very similar to handling events on DOM elements. There are some syntactic differences:
- React events are named using camelCase, rather than lowercase.
- With JSX you pass a function as the event handler, rather than a string.
So as mentioned in React documentation, they quite similar to normal HTML when it comes to Event Handling, but event names in React using camelcase, because they are not really HTML, they are JavaScript, also, you pass the function while we passing function call in a string format for HTML, they are different, but the concepts are pretty similar...
Look at the example below, pay attention to the way event get passed to the function:
function ActionLink() {
function handleClick(e) {
e.preventDefault();
console.log('The link was clicked.');
}
return (
<a href="#" onClick={handleClick}>
Click me
</a>
);
}
See official API documentation https://api.jquery.com/selected-selector/
This good works:
$( "select" ).on('change',function() {
var str = "";
// For multiple choice
$( "select option:selected" ).each(function() {
str += $( this ).val() + " ";
});
});
and
$( "select" ).on('change',function() {
// For unique choice
var selVal = $( "select option:selected" ).val();
});
and be easy for unique choice
var SelVal = $( "#idSelect option:selected" ).val();
You can get rid of the first line. You don't need import java.lang.*;
Just change your 5th line to:
public static void main(String [] args) throws Exception
I got the same problem, in my case I was using svn tortoise with the application I mean. Using the cmd shell of windows in root mode I applied svn cleanup and then svn update.... Then you can comeback to the application mode aand it will work perfectly!
Change the active scheme Device from Simulator to Generic iOS Device
There is a good answer for this and I'm surprised it hasn't been mentioned. With a few lines you can handle dates, models, and everything else.
Make a custom encoder that can handle models:
from django.forms import model_to_dict
from django.core.serializers.json import DjangoJSONEncoder
from django.db.models import Model
class ExtendedEncoder(DjangoJSONEncoder):
def default(self, o):
if isinstance(o, Model):
return model_to_dict(o)
return super().default(o)
Now use it when you use json.dumps
json.dumps(data, cls=ExtendedEncoder)
Now models, dates and everything can be serialized and it doesn't have to be in an array or serialized and unserialized. Anything you have that is custom can just be added to the default
method.
You can even use Django's native JsonResponse this way:
from django.http import JsonResponse
JsonResponse(data, encoder=ExtendedEncoder)
Warning: if you insert numbers one row at a time, you'll end up executing N commands where N is the number of rows you need to insert.
You can get this down to O(log N) by using a temporary table (see below for inserting numbers from 10000 to 10699):
mysql> CREATE TABLE `tmp_keys` (`k` INTEGER UNSIGNED, PRIMARY KEY (`k`));
Query OK, 0 rows affected (0.11 sec)
mysql> INSERT INTO `tmp_keys` VALUES (0),(1),(2),(3),(4),(5),(6),(7);
Query OK, 8 rows affected (0.03 sec)
Records: 8 Duplicates: 0 Warnings: 0
mysql> INSERT INTO `tmp_keys` SELECT k+8 from `tmp_keys`;
Query OK, 8 rows affected (0.02 sec)
Records: 8 Duplicates: 0 Warnings: 0
mysql> INSERT INTO `tmp_keys` SELECT k+16 from `tmp_keys`;
Query OK, 16 rows affected (0.03 sec)
Records: 16 Duplicates: 0 Warnings: 0
mysql> INSERT INTO `tmp_keys` SELECT k+32 from `tmp_keys`;
Query OK, 32 rows affected (0.03 sec)
Records: 32 Duplicates: 0 Warnings: 0
mysql> INSERT INTO `tmp_keys` SELECT k+64 from `tmp_keys`;
Query OK, 64 rows affected (0.03 sec)
Records: 64 Duplicates: 0 Warnings: 0
mysql> INSERT INTO `tmp_keys` SELECT k+128 from `tmp_keys`;
Query OK, 128 rows affected (0.05 sec)
Records: 128 Duplicates: 0 Warnings: 0
mysql> INSERT INTO `tmp_keys` SELECT k+256 from `tmp_keys`;
Query OK, 256 rows affected (0.03 sec)
Records: 256 Duplicates: 0 Warnings: 0
mysql> INSERT INTO `tmp_keys` SELECT k+512 from `tmp_keys`;
Query OK, 512 rows affected (0.11 sec)
Records: 512 Duplicates: 0 Warnings: 0
mysql> INSERT INTO inttable SELECT k+10000 FROM `tmp_keys` WHERE k<700;
Query OK, 700 rows affected (0.16 sec)
Records: 700 Duplicates: 0 Warnings: 0
edit: fyi, unfortunately this won't work with a true temporary table with MySQL 5.0 as it can't insert into itself (you could bounce back and forth between two temporary tables).
edit: You could use a MEMORY storage engine to prevent this from actually being a drain on the "real" database. I wonder if someone has developed a "NUMBERS" virtual storage engine to instantiate virtual storage to create sequences such as this. (alas, nonportable outside MySQL)
This function work like a charm
function toggle_full_screen()
{
if ((document.fullScreenElement && document.fullScreenElement !== null) || (!document.mozFullScreen && !document.webkitIsFullScreen))
{
if (document.documentElement.requestFullScreen){
document.documentElement.requestFullScreen();
}
else if (document.documentElement.mozRequestFullScreen){ /* Firefox */
document.documentElement.mozRequestFullScreen();
}
else if (document.documentElement.webkitRequestFullScreen){ /* Chrome, Safari & Opera */
document.documentElement.webkitRequestFullScreen(Element.ALLOW_KEYBOARD_INPUT);
}
else if (document.msRequestFullscreen){ /* IE/Edge */
document.documentElement.msRequestFullscreen();
}
}
else
{
if (document.cancelFullScreen){
document.cancelFullScreen();
}
else if (document.mozCancelFullScreen){ /* Firefox */
document.mozCancelFullScreen();
}
else if (document.webkitCancelFullScreen){ /* Chrome, Safari and Opera */
document.webkitCancelFullScreen();
}
else if (document.msExitFullscreen){ /* IE/Edge */
document.msExitFullscreen();
}
}
}
To use it just call:
toggle_full_screen();
The bytes int can hold depends on what you compiled it for, so when you compile your program for 32 bit processors, it holds numbers from 2^32/2 to -2^32/2+1, while compiled for 64 bit it can hold from 2^64/2 to -2^64/2+1. int32 will always hold 2^32 values.
Edit : Ignore my answer, I didn't see C#. My answer was intended for C and C++. I've never used C#
It formats the string as two uppercase hexadecimal characters.
In more depth, the argument "X2"
is a "format string" that tells the ToString()
method how it should format the string. In this case, "X2" indicates the string should be formatted in Hexadecimal.
byte.ToString()
without any arguments returns the number in its natural decimal representation, with no padding.
Microsoft documents the standard numeric format strings which generally work with all primitive numeric types' ToString()
methods. This same pattern is used for other types as well: for example, standard date/time format strings can be used with DateTime.ToString()
.
in devices which has Android 4.3 and above you should follow these steps:
How to enable Developer Options:
Launch Settings menu.
Find the open the ‘About Device’ menu.
Scroll down to ‘Build Number’.
Next, tap on the ‘build number’ section seven times.
After the seventh tap you will be told that you are now a developer.
Go back to Settings menu and the Developer Options menu will now be displayed.
In order to enable the USB Debugging you will simply need to open Developer Options, scroll down and tick the box that says ‘USB Debugging’. That’s it.
We can easily do that in css3. We have to simply use @import statement. The following video easily describes the way how to do that. so go ahead and watch it out.
I had to solve a similar problem--I wanted certain styles to only apply to mobile devices in landscape mode. Essentially the fonts and line spacing looked fine in every other context, so I just needed the one exception for mobile landscape. This media query worked perfectly:
@media all and (max-width: 600px) and (orientation:landscape)
{
/* styles here */
}
Use str = ""+a+b+c;
Here the first +
is String
concat, so the result will be a String
. Note where the ""
lies is important.
Or (maybe) better, use a StringBuilder
.
If you facing this issue at the workplace. This might be the solution for you.
pip install -U <package_name> --user --proxy=<your proxy>
I have a similar problem and I resolved in this way:
@RequestMapping(value = "{siteCode}/**/{fileName}.{fileExtension}")
public HttpEntity<byte[]> getResource(@PathVariable String siteCode,
@PathVariable String fileName, @PathVariable String fileExtension,
HttpServletRequest req, HttpServletResponse response ) throws IOException {
String fullPath = req.getPathInfo();
// Calling http://localhost:8080/SiteXX/images/argentine/flag.jpg
// fullPath conentent: /SiteXX/images/argentine/flag.jpg
}
Note that req.getPathInfo()
will return the complete path (with {siteCode}
and {fileName}.{fileExtension}
) so you will have to process conveniently.
I had a PFX file and needed to create KEY file for NGINX, so I did this:
openssl pkcs12 -in file.pfx -out file.key -nocerts -nodes
Then I had to edit the KEY file and remove all content up to -----BEGIN PRIVATE KEY-----
. After that NGINX accepted the KEY file.
Try the 'requests' module, it's much simpler.
#pip install requests for installation
import requests

Yor $.post
has no data. You need to pass the form data. You can use serialize()
to post the form data. Try this
$("#post-btn").click(function(){
$.post("process.php", $('#reg-form').serialize() ,function(data){
alert(data);
});
});
rake gitlab:import:repos might be a more suitable method for mass importing:
repos_path
(/home/git/repositories/group/repo.git
). Directory name must end in .git
and be under a group or user namespace.bundle exec rake gitlab:import:repos
The owner will the first admin, and a group will get created if not already existent.

You don't necessarily have to choose between the two paradigms. You can write software with an OO architecture using many functional concepts. FP and OOP are orthogonal in nature.
Take for example C#. You could say it's mostly OOP, but there are many FP concepts and constructs. If you consider Linq, the most important constructs that permit Linq to exist are functional in nature: lambda expressions.
Another example, F#. You could say it's mostly FP, but there are many OOP concepts and constructs available. You can define classes, abstract classes, interfaces, deal with inheritance. You can even use mutability when it makes your code clearer or when it dramatically increases performance.
Many modern languages are multi-paradigm.
As I'm in the same boat (OOP background, learning FP), I'd suggest you some readings I've really appreciated:
Functional Programming for Everyday .NET Development, by Jeremy Miller. A great article (although poorly formatted) showing many techniques and practical, real-world examples of FP on C#.
Real-World Functional Programming, by Tomas Petricek. A great book that deals mainly with FP concepts, trying to explain what they are, when they should be used. There are many examples in both F# and C#. Also, Petricek's blog is a great source of information.
A little late reply, but what I found in Notepad++ v7.8.6 is, on RMB (Right Mouse Button), on selection text, it gives an option called "Style token" where it shows "Using 1st/2nd/3rd/4th/5th style" to highlight the selected text in different pre-defined colors
Sets the editor data. The data must be provided in the raw format (HTML). CKEDITOR.instances.editor1.setData( 'Put your Data.' ); refer this page
To my knowledge, there isn't a built-in then()
method in javascript
(at the time of this writing).
It appears that whatever it is that doSome("task")
is returning has a method called then
.
If you log the return result of doSome()
to the console, you should be able to see the properties of what was returned.
console.log( myObj.doSome("task") ); // Expand the returned object in the
// console to see its properties.
UPDATE (As of ECMAScript6) :-
The .then()
function has been included to pure javascript.
From the Mozilla documentation here,
The then() method returns a Promise. It takes two arguments: callback functions for the success and failure cases of the Promise.
The Promise object, in turn, is defined as
The Promise object is used for deferred and asynchronous computations. A Promise represents an operation that hasn't completed yet, but is expected in the future.
That is, the Promise
acts as a placeholder for a value that is not yet computed, but shall be resolved in the future. And the .then()
function is used to associate the functions to be invoked on the Promise when it is resolved - either as a success or a failure.
You have to put java in lower case and you have to add .class!
java HelloWorld2.class
You can stringify the JSON Object with JSON.stringify(jsonObject) and receive it on controller as String.
In the Controller, you can use the javax.json to convert and manipulate this.
Download and add the .jar to the project libs and import the JsonObject.
To create an json object, you can use
JsonObjectBuilder job = Json.createObjectBuilder();
job.add("header1", foo1);
job.add("header2", foo2);
JsonObject json = job.build();
To read it from String, you can use
JsonReader jr = Json.createReader(new StringReader(jsonString));
JsonObject json = jsonReader.readObject();
jsonReader.close();
Font's don't have a color; only when using the font you can set the color of the component. For example, when using a JTextArea:
JTextArea txt = new JTextArea();
Font font = new Font("Verdana", Font.BOLD, 12);
txt.setFont(font);
txt.setForeground(Color.BLUE);
According to this link, the createFont() method creates a new Font object with a point size of 1 and style PLAIN. So, if you want to increase the size of the Font, you need to do this:
Font font = Font.createFont(Font.TRUETYPE_FONT, new File("A.ttf"));
return font.deriveFont(12f);
According to nginx documentation
there is no syntax for NOT matching a regular expression. Instead, match the target regular expression and assign an empty block, then use location / to match anything else
So you could define something like
location ~ (dir1|file2\.php) {
# empty
}
location / {
rewrite ^/(.*) http://example.com/$1 permanent;
}
Package php-dom is a virtual package provided by:
php7.1-xml 7.1.3+-3+deb.sury.org~xenial+1
php7.0-xml 7.0.17-3+deb.sury.org~xenial+1
php5.6-xml 5.6.30-9+deb.sury.org~xenial+1
You should explicitly select one to install.
In case anyone using 5.6 versions then go with this way
sudo apt-get install php5.6-xml
For Php Ver PHP7, Ubuntu:
sudo apt-get install php7.1-xml
or by
yum install php-xml
Using UIAppearance you can change it for all headers in your application like this:
UITableViewHeaderFooterView.appearance().backgroundColor = theme.subViewBackgroundColor
You can filter
an array with a closure:
var myList = [1, 2, 3, 4]
var filtered = myList.filter { $0 == 3 } // <= returns [3]
And you can count an array:
filtered.count // <= returns 1
So you can determine if an array includes your element by combining these:
myList.filter { $0 == 3 }.count > 0 // <= returns true if the array includes 3
If you want to find the position, I don't see fancy way, but you can certainly do it like this:
var found: Int? // <= will hold the index if it was found, or else will be nil
for i in (0..x.count) {
if x[i] == 3 {
found = i
}
}
EDIT
While we're at it, for a fun exercise let's extend Array
to have a find
method:
extension Array {
func find(includedElement: T -> Bool) -> Int? {
for (idx, element) in enumerate(self) {
if includedElement(element) {
return idx
}
}
return nil
}
}
Now we can do this:
myList.find { $0 == 3 }
// returns the index position of 3 or nil if not found

With Java9, one can make use of the iterate(int seed, IntPredicate hasNext,IntUnaryOperator next)
as follows:-
List<Integer> indexes = IntStream
.iterate(word.indexOf(c), index -> index >= 0, index -> word.indexOf(c, index + 1))
.boxed()
.collect(Collectors.toList());
System.out.printlnt(indexes);
Is there a name to describe this idiom?
In UML it is called aggregation. It differs from composition in that the member object is not owned by the referring class. In C++ you can implement aggregation in two different ways, through references or pointers.
I am assuming it is to prevent the possibly large overhead of copying a big complex object?
No, that would be a really bad reason to use this. The main reason for aggregation is that the contained object is not owned by the containing object and thus their lifetimes are not bound. In particular the referenced object lifetime must outlive the referring one. It might have been created much earlier and might live beyond the end of the lifetime of the container. Besides that, the state of the referenced object is not controlled by the class, but can change externally. If the reference is not const
, then the class can change the state of an object that lives outside of it.
Is this generally good practice? Are there any pitfalls to this approach?
It is a design tool. In some cases it will be a good idea, in some it won't. The most common pitfall is that the lifetime of the object holding the reference must never exceed the lifetime of the referenced object. If the enclosing object uses the reference after the referenced object was destroyed, you will have undefined behavior. In general it is better to prefer composition to aggregation, but if you need it, it is as good a tool as any other.
Based on Martin Atkins' solution, here is a complete, concise pure-Angular solution:
(function() {
var initInjector = angular.injector(['ng']);
var $http = initInjector.get('$http');
$http.get('/config.json').then(
function (response) {
angular.module('config', []).constant('CONFIG', response.data);
angular.element(document).ready(function() {
angular.bootstrap(document, ['myApp']);
});
}
);
})();
This solution uses a self-executing anonymous function to get the $http service, request the config, and inject it into a constant called CONFIG when it becomes available.
Once completely, we wait until the document is ready and then bootstrap the Angular app.
This is a slight enhancement over Martin's solution, which deferred fetching the config until after the document is ready. As far as I know, there is no reason to delay the $http call for that.
Unit Testing
Note: I have discovered this solution does not work well when unit-testing when the code is included in your app.js
file. The reason for this is that the above code runs immediately when the JS file is loaded. This means the test framework (Jasmine in my case) doesn't have a chance to provide a mock implementation of $http
.
My solution, which I'm not completely satisfied with, was to move this code to our index.html
file, so the Grunt/Karma/Jasmine unit test infrastructure does not see it.

As someone that has ran into this problem constantly with java repositories on Windows, the best solution is to install Cygwin (https://www.cygwin.com/) and use its git installation under all > devel > git.
The reason this is the best solution I have come across is since Cygwin manages the long path names so other provided commands benefit. Ex: find, cp and rm. Trust me, the real problem begins when you have to delete path names that are too long in Windows.
As the table owner you need to grant SELECT access on the underlying tables to the user you are running the SELECT statement as.

I came here with the same above message, but from Azure DevOps.
In my case, I was using docker-compose, not just docker, and writing the build pipeline in yaml.
- task: DockerCompose@0
displayName: 'Push services'
inputs:
azureSubscription: '$(Parameters.azureSubscriptionEndpoint)'
azureContainerRegistry: '$(Parameters.azureContainerRegistry)'
dockerComposeFile: '$(Parameters.dockerComposeFile)'
additionalDockerComposeFiles: |
docker-compose.release.yml
docker-compose.ci.yml
dockerComposeFileArgs: 'PublishFolder=publish'
action: 'Push services'
additionalImageTags: '$(Build.BuildId)'
includeLatestTag: true
The message I got was specifically saying that it was trying to push to docker.io, which was not what I wanted. I had intended this to go to my Azure Container Registry.
Thing that was missing was this line under inputs:
containerregistrytype: Azure Container Registry
The existing pipeline wizard that built the yaml above did not have this line at all. Hopefully this helps someone else pulling their hair out over Azure DevOps.
When you “add” something in Git, you add it to the staging area. When you commit, you then commit what’s in the staging area, meaning it’s possible to commit only a sub-set of changed files at any one time.
In your case, you want to add the folder to the staging area, and then just do a normal commit:
$ git add foldername
$ git commit -m 'Helpful commit message'
The 'as' notation in c# 3.0 is very clean. Since all session variables are nullable objects, this lets you grab the value and put it into your own typed variable without worry of throwing an exception. Most objects can be handled this way.
string mySessionVar = Session["mySessionVar"] as string;
My concept is that you should pull your Session variables into local variables and then handle them appropriately. Always assume your Session variables could be null and never cast them into a non-nullable type.
If you need a non-nullable typed variable you can then use TryParse to get that.
int mySessionInt;
if (!int.TryParse(mySessionVar, out mySessionInt)){
// handle the case where your session variable did not parse into the expected type
// e.g. mySessionInt = 0;
}
You can enable SSL on XAMPP by creating self signed certificates and then installing those certificates. Type the below commands to generate and move the certificates to ssl folders.
openssl genrsa -des3 -out server.key 1024
openssl req -new -key server.key -out server.csr
cp server.key server.key.org
openssl rsa -in server.key.org -out server.key
openssl x509 -req -days 365 -in server.csr -signkey server.key -out server.crt
cp server.crt /opt/lampp/etc/ssl.crt/domainname.crt
cp server.key /opt/lampp/etc/ssl.key/domainname.key
(Use sudo with each command if you are not the super user)
Now, Check that mod_ssl is enabled in [XAMPP_HOME]/etc/httpd.conf:
LoadModule ssl_module modules/mod_ssl.so
Add a virtual host, in this example "localhost.domainname.com" by editing [XAMPP_HOME]/etc/extra/httpd-ssl.conf as follows:
<virtualhost 127.0.1.4:443>
ServerName localhost.domainname.com
ServerAlias localhost.domainname.com *.localhost.domainname.com
ServerAdmin admin@localhost
DocumentRoot "/opt/lampp/htdocs/"
DirectoryIndex index.php
ErrorLog /opt/lampp/logs/domainname.local.error.log
CustomLog /opt/lampp/logs/domainname.local.access.log combined
SSLEngine on
SSLCipherSuite ALL:!ADH:!EXPORT56:RC4+RSA:+HIGH:+MEDIUM:+LOW:+SSLv2:+EXP:+eNULL
SSLCertificateFile /opt/lampp/etc/ssl.crt/domainname.crt
SSLCertificateKeyFile /opt/lampp/etc/ssl.key/domainname.key
<directory /opt/lampp/htdocs/>
Options Indexes FollowSymLinks
AllowOverride All
Order allow,deny
Allow from all
</directory>
BrowserMatch ".*MSIE.*" nokeepalive ssl-unclean-shutdown downgrade-1.0 force-response-1.0
</virtualhost>
Add the following entry to /etc/hosts:
127.0.1.4 localhost.domainname.com
Now, try installing the certificate/ try importing certificate to browser. I have checked this and this worked on Ubuntu.
Before running the command try entering:
export JAVA_HOME="path_to_java_home"
Where path_to_java_home
is the folder where your bin/java
is.
If java is properly installed you can find it's location, by using the command:
readlink -f $(which java)
Don't forget to remove bin/java

I had a similar problem when deploying one of my portlets. The portlet has been developed for Liferay 6.2 on Windows. My runtime environment is Tomcat 7 running on JRE 1.6 (JRockit 1.6). I have recently migrated to Eclipse 2019-3. I checked my Java Build Path (Project->Properties, Libraries tab). I noticed that the Apache Tomcat that is specified in the list of JARs and class folders on the build path was unbound. I selected that item. I clicked on the Edit button. Server Libary dialog was opened. I selected the correct Apache Tomcat. After applying the change, I redeployed the portlet and the problem was resolved.
Sometimes you may need to delete the problematic portlet from the [Tomcat]/webapps
directory before deploying the corrected portlet. Also, sometimes I have experienced that deployment of a portlet takes more than usual, and redeploying it resolves the issue.
Size of a pointer should be 8 byte on any 64-bit C/C++ compiler, but not necessarily size of int.
You can use StringEscapeUtils from Apache Commons Logging utility or escape manually using code for each character.
I now found solution by using mysqli
instead of mysql
.
<?php
// enable error reporting
mysqli_report(MYSQLI_REPORT_ERROR | MYSQLI_REPORT_STRICT);
//connect to database
$connection = mysqli_connect("hostname", "user", "password", "db", "port");
//run the store proc
$result = mysqli_query($connection, "CALL StoreProcName");
//loop the result set
while ($row = mysqli_fetch_array($result)){
echo $row[0] . " - " . + $row[1];
}
I found that many people seem to have a problem with using mysql_connect, mysql_query and mysql_fetch_array
.
This is with jQuery.
$('#selectFormElement').change( function() {
$('#hiddenFormElement').val('newValue');
} );
In the html
<select id="selectFormElement" name="..."> ... </select>
<input type="hidden" name="..." id="hiddenFormElement" />
To expand on the accepted answer, I just wanted to provide another reason why real
? user
+ sys
.
Keep in mind that real
represents actual elapsed time, while user
and sys
values represent CPU execution time. As a result, on a multicore system, the user
and/or sys
time (as well as their sum) can actually exceed the real time. For example, on a Java app I'm running for class I get this set of values:
real 1m47.363s
user 2m41.318s
sys 0m4.013s
just type
attrib -h -r -s /s /d j:*.*
where j is the drive letter... unlocks all the locked stuff in j drive
if u want to make it specific..then go to a specific location using cmd and then type
attrib -h -r -s /s /d "foldername"
it can also be used to lock drives or folders just alter "-" with "+"
attrib +h +r +s /s /d "foldername"
You can also use JSONObject class from json.org to this will convert your HashMap to JSON string which is well formatted
Example:
Map<String,Object> map = new HashMap<>();
map.put("myNumber", 100);
map.put("myString", "String");
JSONObject json= new JSONObject(map);
String result= json.toString();
System.out.print(result);
result:
{'myNumber':100, 'myString':'String'}
Your can also get key from it like
System.out.print(json.get("myNumber"));
result:
100
Fixing Error code 1206: The number of locks exceeds the lock table size.
In my case, I work with MySQL Workbench (5.6.17) running on Windows with WampServer 2.5.
For Windows/WampServer you have to edit the my.ini file (not the my.cnf file)
To locate this file go to Menu Server/Server Status (in MySQL Workbench) and look under Server Directories/ Base Directory
In my.ini file there are defined sections for different settings, look for section [mysqld] (create it if it does not exist) and add the command: innodb_buffer_pool_size=4G
[mysqld]
innodb_buffer_pool_size=4G
The size of the buffer_pool file will depend on your specific machine, in most cases, 2G or 4G will fix the problem.
Remember to restart the server so it takes the new configuration, it corrected the problem for me.
Hope it helps!
This might not be a suitable solution for the console, but Rails has a method for this problem: Logger#silence

Sure, find where -Werror
is set and remove that flag. Then warnings will be only warnings.
Even better:

FROM dbo.EvenRows AS o
CROSS JOIN (SELECT c = COUNT(*) FROM dbo.EvenRows) AS c
) AS x
WHERE rn IN ((c + 1)/2, (c + 2)/2);

imread is depreciated after version 1.2.0! So to solve this issue I had to install version 1.1.0.
pip install scipy==1.1.0
I realize this is an old thread but wanted to post a solution similar to your request for a function (just ran into the similar issue myself trying to format an entire table to percentage labels).
Assume you have a df with 5 character columns you want to convert. First, I create a table containing the names of the columns I want to manipulate:
col_to_convert <- data.frame(nrow = 1:5
,col = c("col1","col2","col3","col4","col5"))
for (i in 1:max(cal_to_convert$row))
{
colname <- col_to_convert$col[i]
colnum <- which(colnames(df) == colname)
for (j in 1:nrow(df))
{
df[j,colnum] <- as.numericdf(df[j,colnum])
}
}
This is not ideal for large tables as it goes cell by cell, but it would get the job done.
Below is a semester long course distilled in a few paragraphs.
Object-Oriented Analysis and Design (OOAD) is actually based on not just two but four principles. They are:
Abstraction: means that you only incorporate those features of an entity which are required in your application. So, if every bank account has an opening date but your application doesn't need to know an account's opening date, then you simply don't add the OpeningDate field in your Object-Oriented Design (of the BankAccount class). †Abstraction in OOAD has nothing to do with abstract classes in OOP.
Per the principle of Abstraction, your entities are an abstraction of what they are in the real world. This way, you design an abstraction of Bank Account down to only that level of detail that is needed by your application.
Inheritance: is more of a coding-trick than an actual principle. It saves you from re-writing those functionalities that you have written somewhere else. However, the thinking is that there must be a relation between the new code you are writing and the old code you are wanting to re-use. Otherwise, nobody prevents you from writing an Animal class which is inheriting from BankAccount, even if it is totally non-sensical.
Just like you may inherit your parents' wealth, you may inherit fields and methods from your parent class. So, taking everything that parent class has and then adding something more if need be, is inheritance. Don't go looking for inheritance in your Object Oriented Design. Inheritance will naturally present itself.
Polymorphism: is a consequence of inheritance. Inheriting a method from the parent is useful, but being able to modify a method if the situation demands, is polymorphism. You may implement a method in the subclass with exactly the same signature as in parent class so that when called, the method from child class is executed. This is the principle of Polymorphism.
Encapsulation: implies bundling the related functionality together and giving access to only the needful. Encapsulation is the basis of meaningful class designing in Object Oriented Design, by:
Another simplified answer is here.
† People who argue that "Abstraction of OOAD results in the abstract keyword of OOP"... Well that is incorrect.
Example: When you design a University in an application using object oriented principles, you only design an "abstraction" of the university. Even though there is usually one cash dispensing ATM in almost every university, you may not incorporate that fact if it's not needed for your application. And now though you have designed only an abstraction of the university, you are not required to put abstract in your class declaration. Your abstract design of university will be a normal class in your application.
I normally use the HttpPostedFileBase parameter only in Mvc Controllers. When dealing with ApiControllers try checking the HttpContext.Current.Request.Files property for incoming files instead:
[HttpPost]
public string UploadFile()
{
var file = HttpContext.Current.Request.Files.Count > 0 ?
HttpContext.Current.Request.Files[0] : null;
if (file != null && file.ContentLength > 0)
{
var fileName = Path.GetFileName(file.FileName);
var path = Path.Combine(
HttpContext.Current.Server.MapPath("~/uploads"),
fileName
);
file.SaveAs(path);
}
return file != null ? "/uploads/" + file.FileName : null;
}
I changed the content-type to "text/html" instead of "application/json" server side before returning the response. Described it in a blog post, where other solutions have also been added:
http://blog.degree.no/2012/09/jquery-json-ie8ie9-treats-response-as-downloadable-file/
SQL Plus will format the columns to hold the maximum possible value, which in this case is 255 characters.
To confirm that your output does not actually contain those extra spaces, try this:
SELECT
'/' || TRIM(A) || '/' AS COLUMN_A
,'/' || TRIM(B) || '/' AS COLUMN_B
FROM
MY_TABLE;
If the '/' characters are separated from your output, then that indicates that it's not spaces, but some other whitespace character that got in there (tabs, for example). If that is the case, then it is probably an input validation issue somewhere in your application.
However, the most likely scenario is that the '/' characters will in fact touch the rest of your strings, thus proving that the whitespace is actually trimmed.
If you wish to output them together, then the answer given by Quassnoi should do it.
If it is purely a display issue, then the answer given by Tony Andrews should work fine.

A quick hack while debugging that works without having to import pprint
would be to join the list on '\n'
.
>>> lst = ['foo', 'bar', 'spam', 'egg']
>>> print '\n'.join(lst)
foo
bar
spam
egg
You can create a folder name as Resources within the project using Solution Explorer,then you can paste a file within the Resources.
private void Form1_Load(object sender, EventArgs e) {
string appName = Environment.CurrentDirectory;
int l = appName.Length;
int h = appName.LastIndexOf("bin");
string ll = appName.Remove(h);
string g = ll + "Resources\\sample.txt";
System.Diagnostics.Process.Start(g);
}
If you have an Instance of the EditText available at the point in your code where you want add whitespace, then this code below will work. There may be some things to consider, for example the code below may trigger any TextWatcher you have set to this EditText, idk for sure, just saying, but this will work when trying to append blank space like this: " ", hasn't worked.
messageInputBox.dispatchKeyEvent(new KeyEvent(0, 0, 0, KeyEvent.KEYCODE_SPACE, 0, 0, 0, 0,

Do you have two connections at the same time? If so, close every time you don't need it.
Suppose you have a data frame(say df) with columns "x" and "y", you can find mean of column (x or y) using:
1.Using mean() function
z<-mean(df$x)
2.Using the column name(say x) as a variable using attach()
function
attach(df)
mean(x)
When done you can call detach()
to remove "x"
detach()
3.Using with()
function, it lets you use columns of data frame as distinct variables.
z<-with(df,mean(x))
You can use the XML Instance Generator which is part of the Sun/Oracle Multi-Schema Validator.
It's README.txt states:
Sun XML Generator is a Java tool to generate various XML instances from several kinds of schemas. It supports DTD, RELAX Namespace, RELAX Core, TREX, and a subset of W3C XML Schema Part 1. [...]
This is a command-line tool that can generate both valid and invalid instances from schemas. It can be used for generating test cases for XML applications that need to conform to a particular schema.
Download and unpack xmlgen.zip
from the msv download page and run the following command to get detailed usage instructions:
java -jar xmlgen.jar -help
The tool appears to be released under a BSD license; the source code is accessible from here

EDIT: chardet seems to be unmantained but most of the answer applies. Check https://pypi.org/project/charset-normalizer/ for an alternative
Correctly detecting the encoding all times is impossible.
(From chardet FAQ:)
However, some encodings are optimized for specific languages, and languages are not random. Some character sequences pop up all the time, while other sequences make no sense. A person fluent in English who opens a newspaper and finds “txzqJv 2!dasd0a QqdKjvz” will instantly recognize that that isn't English (even though it is composed entirely of English letters). By studying lots of “typical” text, a computer algorithm can simulate this kind of fluency and make an educated guess about a text's language.
There is the chardet library that uses that study to try to detect encoding. chardet is a port of the auto-detection code in Mozilla.
You can also use UnicodeDammit. It will try the following methods:
Using an RDP connection file you can set the alternate shell to be your application; the file syntax is like
alternate shell:s:c:\winnt\system32\notepad.exe
and you pass that as a command-line argument to mstsc.exe; this similar to chrissr's solution, but without affecting every RDP session you launch. A fuller summary of settings here.
I know this was quite a while ago, however I have a little extra to add:
This is not possible in HTML5 or any previous specs, nor is it proposed in HTML5.1 yet. I have made a request to the public-html-comments

As an extra added benefit, this also means you can allow selection of the <optgroups>
themselves. This might be useful if you had, for example, nested categories where the categories go into heavy detail and you want to allow users to select higher up in the hierarchy.
This will all work without JavaScript, however you might wish to add some to hide the radio buttons and then change the background color of the selected item or something.
Bear in mind, this is far from a perfect solution, but if you absolutely need a nested select with reasonable cross-browser compatibility, this is probably as close as you're going to get.
This function will convert integer to binary in C#:
public static string ToBinary(int N)
{
int d = N;
int q = -1;
int r = -1;
string binNumber = string.Empty;
while (q != 1)
{
r = d % 2;
q = d / 2;
d = q;
binNumber = r.ToString() + binNumber;
}
binNumber = q.ToString() + binNumber;
return binNumber;
}
There is no default database for user. There is default database for current session.
You can get it using DATABASE() function -
SELECT DATABASE();
And you can set it using USE statement -
USE database1;
You should set it manually - USE db_name
, or in the connection string.

If you're looking for a Facebook like scroll bar, then I'd highly recommend you take a look at this one:
I think you want to do this instead:
from __future__ import with_statement
with open("out.txt","wt") as file_out:
with open("in.txt") as file_in:
for line in file_in:
file_out.write(line)
It is possible to do (in the deployed repository)
git fetch
git checkout origin/master -- path/to/file
The fetch will download all the recent changes, but it will not put it in your current checked out code (working area).
The checkout will update the working tree with the particular file from the downloaded changes (origin/master
).
At least this works for me for those little small typo fixes, where it feels weird to create a branch etc just to change one word in a file.
I faced a similar problem, on my Windows computer, please do check that you have set the Environment Variables correctly.
To check that Environment variable is set correctly:
Open cmd.exe
Type Python and press return
(a) If it outputs the version of python then the environment variables are set correctly.
(b) If it outputs "no such program or file name" then your environment variable are not set correctly.
To set environment variable:
If you have correct variables already set; then you are calling the file inside the python interpreter.
I won't repost the other answers because they're all correct, but I'll just add that you can't use switch for more "complicated" statements, eg: to test if a value is "greater than 3", "between 4 and 6", etc. If you need to do something like that, stick to using if
statements, or if there's a particularly strong need for switch
then it's possible to use it back to front:
switch (true) {
case ($value > 3) :
// value is greater than 3
break;
case ($value >= 4 && $value <= 6) :
// value is between 4 and 6
break;
}
but as I said, I'd personally use an if
statement there.
pip
is designed to upgrade python packages and not to upgrade python itself. pip

To get a type that implements io.Reader
from a []byte
slice, you can use bytes.NewReader
in the bytes
package:
r := bytes.NewReader(byteData)
This will return a value of type bytes.Reader
which implements the io.Reader
(and io.ReadSeeker
) interface.
Don't worry about them not being the same "type". io.Reader
is an interface and can be implemented by many different types. To learn a little bit more about interfaces in Go, read Effective Go: Interfaces and Types.
You may find that you have to link with the math libraries on whatever system you're using, something like:
gcc -o myprog myprog.c -L/path/to/libs -lm
^^^ - this bit here.
Including headers lets a compiler know about function declarations but it does not necessarily automatically link to the code required to perform that function.
Failing that, you'll need to show us your code, your compile command and the platform you're running on (operating system, compiler, etc).
The following code compiles and links fine:
#include <math.h>
int main (void) {
int max = sqrt (9);
return 0;
}
Just be aware that some compilation systems depend on the order in which libraries are given on the command line. By that, I mean they may process the libraries in sequence and only use them to satisfy unresolved symbols at that point in the sequence.
So, for example, given the commands:
gcc -o plugh plugh.o -lxyzzy
gcc -o plugh -lxyzzy plugh.o
and plugh.o
requires something from the xyzzy
library, the second may not work as you expect. At the point where you list the library, there are no unresolved symbols to satisfy.
And when the unresolved symbols from plugh.o
do appear, it's too late.
how about making the heading a list-element with different styles like so
<ul>
<li class="heading">heading</li>
<li>list item</li>
<li>list item</li>
<li>list item</li>
<li>list item</li>
</ul>
and the CSS
ul .heading {font-weight: normal; list-style: none;}
additionally, use a reset CSS to set margins and paddings right on the ul and li. here's a good reset CSS. once you've reset the margins and paddings, you can apply some margin on the list-elements other than the one's with the heading class, to indent them.

My manifest does not reference any themes... it should not have to AFAIK
Sure it does. Nothing is going to magically apply Theme.Styled
to an activity. You need to declare your activities -- or your whole application -- is using Theme.Styled
, e.g., :
<application
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme="@style/Theme.Styled">
The main problem was that you were opening/closing files repeatedly inside your loop.
Try this approach:
with open('new.txt') as text_file, open('xyz.txt', 'w') as myfile:
for line in text_file:
var1, var2 = line.split(",");
myfile.write(var1+'\n')
We open both files at once and because we are using with
they will be automatically closed when we are done (or an exception occurs). Previously your output file was repeatedly openend inside your loop.
We are also processing the file line-by-line, rather than reading all of it into memory at once (which can be a problem when you deal with really big files).
Note that write()
doesn't append a newline ('\n'
) so you'll have to do that yourself if you need it (I replaced your writelines()
with write()
as you are writing a single item, not a list of items).
When opening a file for r
read, the 'r'
is optional since it's the default mode.
It is a little late but it might help someone. I created a procedure sometimes back which does the following using T-SQL:

Edit: Thanks Marc, read up on the struct vs class issue and you're right, thank you!
I tend to use the following method for doing what you describe, using a static method of JSon.Net:
MyObject deserializedObject = JsonConvert.DeserializeObject<MyObject>(json);
Link: Serializing and Deserializing JSON with Json.NET
For the Objects list, may I suggest using generic lists out made out of your own small class containing attributes
and position
class. You can use the Point
struct in System.Drawing
(System.Drawing.Point
or System.Drawing.PointF
for floating point numbers) for you X and Y.
After object creation it's much easier to get the data you're after vs. the text parsing you're otherwise looking at.
Here is complete demo code to understand client side and server side process. you can copy paste it and just replace google site key and google secret key.

if(!empty($_REQUEST))
{
// echo '<pre>'; print_r($_REQUEST); die('END');
$post = [
'secret' => 'Your Secret key',
'response' => $_REQUEST['g-recaptcha-response'],
];
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,"https://www.google.com/recaptcha/api/siteverify");
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($post));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$server_output = curl_exec($ch);
curl_close ($ch);
echo '<pre>'; print_r($server_output); die('ss');

Example with Unix-style file name:
COPY (SELECT * FROM tbl) TO '/var/lib/postgres/myfile1.csv' format csv;
Read the manual about COPY
(link to version 8.2).
You have to use an absolute path for the target file. Be sure to double quote file names with spaces. Example for MS Windows:
COPY (SELECT * FROM tbl)
TO E'"C:\\Documents and Settings\\Tech\Desktop\\myfile1.csv"' format csv;
In PostgreSQL 8.2, with standard_conforming_strings = off
per default, you need to double backslashes, because \
is a special character and interpreted by PostgreSQL. Works in any version. It's all in the fine manual:
filename
The absolute path name of the input or output file. Windows users might need to use an
E''
string and double backslashes used as path separators.
Or the modern syntax with standard_conforming_strings = on
(default since Postgres 9.1):
COPY tbl -- short for (SELECT * FROM tbl)
TO '"C:\Documents and Settings\Tech\Desktop\myfile1.csv"' (format csv);
Or you can also use forward slashes for filenames under Windows.
An alternative is to use the meta-command \copy
of the default terminal client psql
.
You can also use a GUI like pgadmin and copy / paste from the result grid to Excel for small queries.

Similar solution for MySQL:
The ISO is probably pre-pidded. You'll need to delete the key from the setup files. It should then ask you for a key during installation.
Regex if you want to ensure URL starts with HTTP/HTTPS:
https?:\/\/(www\.)?[-a-zA-Z0-9@:%._\+~#=]{1,256}\.[a-zA-Z0-9()]{1,6}\b([-a-zA-Z0-9()@:%_\+.~#?&//=]*)
If you do not require HTTP protocol:
[-a-zA-Z0-9@:%._\+~#=]{1,256}\.[a-zA-Z0-9()]{1,6}\b([-a-zA-Z0-9()@:%_\+.~#?&//=]*)
To try this out see http://regexr.com?37i6s, or for a version which is less restrictive http://regexr.com/3e6m0.
Example JavaScript implementation:
var expression = /[-a-zA-Z0-9@:%._\+~#=]{1,256}\.[a-zA-Z0-9()]{1,6}\b([-a-zA-Z0-9()@:%_\+.~#?&//=]*)?/gi;_x000D_

Update
My recomendation would be to shred the XML into relations and do searches and joins on the resulted relation, in a set oriented fashion, rather than the procedural fashion of searching specific nodes in the XML. Here is a simple XML query that shreds out the nodes and attributes of interest:
select x.value(N'../../../../@stepId', N'int') as StepID
, x.value(N'../../@id', N'int') as ComponentID
, x.value(N'@nom',N'nvarchar(100)') as Nom
, x.value(N'@valeur', N'nvarchar(100)') as Valeur
from @x.nodes(N'/xml/box/components/component/variables/variable') t(x)
However, if you must use an XPath that retrieves exactly the value of interest:
select x.value(N'@valeur', N'nvarchar(100)') as Valeur
from @x.nodes(N'/xml/box[@stepId=sql:variable("@stepID")]/
components/component[@id = sql:variable("@componentID")]/
variables/variable[@nom="Enabled"]') t(x)
If the stepID and component ID are columns, not variables, the you should use sql:column() instead of sql:variable in the XPath filters. See Binding Relational Data Inside XML Data.
And finaly if all you need is to check for existance you can use the exist() XML method:
select @x.exist(
N'/xml/box[@stepId=sql:variable("@stepID")]/
components/component[@id = sql:variable("@componentID")]/
variables/variable[@nom="Enabled" and @valeur="Yes"]')
I was using below command
git clone -b branch-name https://<username>@bitbucket.org/<repository>.git
Issue got resolved after adding password with username (see below command):
git clone -b branch-name https://<username>:<password>@bitbucket.org/<repository>.git
In case anyone missed the comments on the original question, you can use built-in methods (works as of Moment 1.7):
const startOfMonth = moment().clone().startOf('month').format('YYYY-MM-DD hh:mm');
const endOfMonth = moment().clone().endOf('month').format('YYYY-MM-DD hh:mm');

Define versionName in AndroidManifest.xml
android:versionName="5.1.5"
Inside android{...}
block in build.gradle
of app level :
defaultConfig {
applicationId "com.example.autoincrement"
minSdkVersion 18
targetSdkVersion 23
multiDexEnabled true
def version = getIncrementationVersionName()
versionName version
}
Outside android{...}
block in build.gradle
of app level :
def getIncrementedVersionName() {
List<String> runTasks = gradle.startParameter.getTaskNames();
//find version name in manifest
def manifestFile = file('src/main/AndroidManifest.xml')
def matcher = Pattern.compile('versionName=\"(\\d+)\\.(\\d+)\\.(\\d+)\"').matcher(manifestFile.getText())
matcher.find()
//extract versionName parts
def firstPart = Integer.parseInt(matcher.group(1))
def secondPart = Integer.parseInt(matcher.group(2))
def thirdPart = Integer.parseInt(matcher.group(3))
//check is runTask release or not
// if release - increment version
for (String item : runTasks) {
if (item.contains("assemble") && item.contains("Release")) {
thirdPart++
if (thirdPart == 10) {
thirdPart = 0;
secondPart++
if (secondPart == 10) {
secondPart = 0;
firstPart++
}
}
}
}
def versionName = firstPart + "." + secondPart + "." + thirdPart
// update manifest
def manifestContent = matcher.replaceAll('versionName=\"' + versionName + '\"')
manifestFile.write(manifestContent)
println "incrementVersionName = " + versionName
return versionName
}
After create singed APK :
android:versionName="5.1.6"
Note : If your versionName different from my, you need change regex and extract parts logic.
Actually, you should avoid using this
when using react hooks. It causes side effects. That's why react team create react hooks
.
If you remove codes that tries to bind this
, you can just simply pass setName
of Parent
to Child
and call it in handleChange
. Cleaner code!
function Parent() {
const [Name, setName] = useState("");
return <div> {Name} :
<Child setName={setName} ></Child>
</div>
}
function Child(props) {
const [Name, setName] = useState("");
function handleChange(ele) {
setName(ele.target.value);
props.setName(ele.target.value);
}
return (<div>
<input onChange={handleChange} value={Name}></input>
</div>);
}
Moreover, you don't have to create two copies of Name
(one in Parent
and the other one in Child
). Stick to "Single Source of Truth" principle, Child
doesn't have to own the state Name
but receive it from Parent
. Cleanerer node!
function Parent() {
const [Name, setName] = useState("");
return <div> {Name} :
<Child setName={setName} Name={Name}></Child>
</div>
}
function Child(props) {
function handleChange(ele) {
props.setName(ele.target.value);
}
return (<div>
<input onChange={handleChange} value={props.Name}></input>
</div>);
}
CancelAsync
doesn't actually abort your thread or anything like that. It sends a message to the worker thread that work should be cancelled via BackgroundWorker.CancellationPending
. Your DoWork delegate that is being run in the background must periodically check this property and handle the cancellation itself.
The tricky part is that your DoWork delegate is probably blocking, meaning that the work you do on your DataSource must complete before you can do anything else (like check for CancellationPending). You may need to move your actual work to yet another async delegate (or maybe better yet, submit the work to the ThreadPool
), and have your main worker thread poll until this inner worker thread triggers a wait state, OR it detects CancellationPending.

If DVI to SVG is an option, you can also use dvisvgm to convert a DVI file to an SVG file. This works perfectly for instance for LaTeX formulas (with option --no-fonts
):
dvisvgm --no-fonts input.dvi -o output.svg
There is also pdf2svg which uses poppler and Cairo to convert a pdf into SVG. When I tried this, the SVG was perfectly rendered in inkscape
.
You would use JodaTime for that. Java.util.Date is very limited regarding TimeZone.
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>
I don't think you can design the if-then-else construct without taking the design for other constructs into account. I think it's a good principle that each expression should be an element, and its subexpressions should be child elements. There are then questions about whether the name of an element should reflect the type of expression it is, or its role relative to the parent. Or you can do both:
<if>
<condition>
<equals>
<number>2</number>
<number>3</number>
<equals>
<condition>
<then>
<string>Mary</string>
</then>
<else>
<concat>
<string>John</string>
<string>Smith</string>
</concat>
</else>
</if>
But you can sometimes get away with a design that omits the role-names (condition, then else) and relies on positional significance of elements relative to their parent. It depends a bit on how much you want to keep it concise.
For long arrays
s = np.empty(len(var))
s[:] = np.nan
for x in set(var):
x_positions = np.where(var==x)
s[x_positions[0][0]]=x
sorted_var=s[~np.isnan(s)]
Unfortunately MSTest STILL only really has the ExpectedException attribute (just shows how much MS cares about MSTest) which IMO is pretty awful because it breaks the Arrange/Act/Assert pattern and it doesnt allow you to specify exactly which line of code you expect the exception to occur on.
When I'm using (/forced by a client) to use MSTest I always use this helper class:
public static class AssertException
{
public static void Throws<TException>(Action action) where TException : Exception
{
try
{
action();
}
catch (Exception ex)
{
Assert.IsTrue(ex.GetType() == typeof(TException), "Expected exception of type " + typeof(TException) + " but type of " + ex.GetType() + " was thrown instead.");
return;
}
Assert.Fail("Expected exception of type " + typeof(TException) + " but no exception was thrown.");
}
public static void Throws<TException>(Action action, string expectedMessage) where TException : Exception
{
try
{
action();
}
catch (Exception ex)
{
Assert.IsTrue(ex.GetType() == typeof(TException), "Expected exception of type " + typeof(TException) + " but type of " + ex.GetType() + " was thrown instead.");
Assert.AreEqual(expectedMessage, ex.Message, "Expected exception with a message of '" + expectedMessage + "' but exception with message of '" + ex.Message + "' was thrown instead.");
return;
}
Assert.Fail("Expected exception of type " + typeof(TException) + " but no exception was thrown.");
}
}
Example of usage:
AssertException.Throws<ArgumentNullException>(() => classUnderTest.GetCustomer(null));
For my case, I was trying to execute procedure code in MySQL, and due to some issue with server in which Server can't figure out where to end the statement I was getting Error Code 1064. So I wrapped the procedure with custom DELIMITER and it worked fine.
For example, Before it was:
DROP PROCEDURE IF EXISTS getStats;
CREATE PROCEDURE `getStats` (param_id INT, param_offset INT, param_startDate datetime, param_endDate datetime)
BEGIN
/*Procedure Code Here*/
END;
After putting DELIMITER it was like this:
DROP PROCEDURE IF EXISTS getStats;
DELIMITER $$
CREATE PROCEDURE `getStats` (param_id INT, param_offset INT, param_startDate datetime, param_endDate datetime)
BEGIN
/*Procedure Code Here*/
END;
$$
DELIMITER ;
I suppose because you didn't specify plugin version so it triggers the download of associated metadata in order to get the last one.
Otherwise did you try to force local repo usage using -o ?
With the plugin: jQuery Selection Box. You can do this:
var myOptions = {
"Value 1" : "Text 1",
"Value 2" : "Text 2",
"Value 3" : "Text 3"
}
$("#myselect2").addOption(myOptions, false);
The answer that has 50 votes doesn't check for date in only checks for months. That answer is not correct. The code below works.
var dateFrom = "01/08/2017";
var dateTo = "01/10/2017";
var dateCheck = "05/09/2017";
var d1 = dateFrom.split("/");
var d2 = dateTo.split("/");
var c = dateCheck.split("/");
var from = new Date(d1); // -1 because months are from 0 to 11
var to = new Date(d2);
var check = new Date(c);
alert(check > from && check < to);
This is the code posted in another answer and I have changed the dates and that's how I noticed it doesn't work
var dateFrom = "02/05/2013";
var dateTo = "02/09/2013";
var dateCheck = "07/07/2013";
var d1 = dateFrom.split("/");
var d2 = dateTo.split("/");
var c = dateCheck.split("/");
var from = new Date(d1[2], parseInt(d1[1])-1, d1[0]); // -1 because months are from 0 to 11
var to = new Date(d2[2], parseInt(d2[1])-1, d2[0]);
var check = new Date(c[2], parseInt(c[1])-1, c[0]);
alert(check > from && check < to);
This worked for me to return an array of strings from my config:
var allowedMethods = Configuration.GetSection("AppSettings:CORS-Settings:Allow-Methods")
.Get<string[]>();
My configuration section looks like this:
"AppSettings": {
"CORS-Settings": {
"Allow-Origins": [ "http://localhost:8000" ],
"Allow-Methods": [ "OPTIONS","GET","HEAD","POST","PUT","DELETE" ]
}
}
You can do:
import matplotlib.pyplot as plt
x = [1,2,3,4,5]
y = [2,1,3,6,7]
plt.plot(x, y, style='.-')
plt.show()
This will return a graph with the data points marked with a dot
if you want to call controller from form action that time used following code:
<form action="{{ action('SchoolController@getSchool') }}" >
Here SchoolController
is a controller name and getSchool
is a method name, you must use get
or post
before method name which should be same as in form tag.
You have to load jdbc driver
. Consider below Code.
try {
Class.forName("com.mysql.jdbc.Driver");
// connect way #1
String url1 = "jdbc:mysql://localhost:3306/aavikme";
String user = "root";
String password = "aa";
conn1 = DriverManager.getConnection(url1, user, password);
if (conn1 != null) {
System.out.println("Connected to the database test1");
}
// connect way #2
String url2 = "jdbc:mysql://localhost:3306/aavikme?user=root&password=aa";
conn2 = DriverManager.getConnection(url2);
if (conn2 != null) {
System.out.println("Connected to the database test2");
}
// connect way #3
String url3 = "jdbc:mysql://localhost:3306/aavikme";
Properties info = new Properties();
info.put("user", "root");
info.put("password", "aa");
conn3 = DriverManager.getConnection(url3, info);
if (conn3 != null) {
System.out.println("Connected to the database test3");
}
} catch (SQLException ex) {
System.out.println("An error occurred. Maybe user/password is invalid");
ex.printStackTrace();
} catch (ClassNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
If you mean returning multiple values, you can either return a class/struct containing the values you want to return, or use the "out" keyword on your parameters, like so:
public void Foo(int input, out int output1, out string output2, out string errors) {
// set out parameters inside function
}
The sort
command prints the result of the sorting operation to standard output by default. In order to achieve an "in-place" sort, you can do this:
sort -o file file
This overwrites the input file
with the sorted output. The -o
switch, used to specify an output, is defined by POSIX, so should be available on all version of sort
:
-o Specify the name of an output file to be used instead of the standard output. This file can be the same as one of the input files.
If you are unfortunate enough to have a version of sort
without the -o
switch (Luis assures me that they exist), you can achieve an "in-place" edit in the standard way:
sort file > tmp && mv tmp file
You can use the pgrep command like in the following example
$ pgrep Keychain\ Access
44186
As others have explained, the built-in dict
does not do what you want. But in Python2 (and probably 3 too) you can easily create a ValueDict
class that copies with =
so you can be sure that the original will not change.
class ValueDict(dict):
def __ilshift__(self, args):
result = ValueDict(self)
if isinstance(args, dict):
dict.update(result, args)
else:
dict.__setitem__(result, *args)
return result # Pythonic LVALUE modification
def __irshift__(self, args):
result = ValueDict(self)
dict.__delitem__(result, args)
return result # Pythonic LVALUE modification
def __setitem__(self, k, v):
raise AttributeError, \
"Use \"value_dict<<='%s', ...\" instead of \"d[%s] = ...\"" % (k,k)
def __delitem__(self, k):
raise AttributeError, \
"Use \"value_dict>>='%s'\" instead of \"del d[%s]" % (k,k)
def update(self, d2):
raise AttributeError, \
"Use \"value_dict<<=dict2\" instead of \"value_dict.update(dict2)\""
# test
d = ValueDict()
d <<='apples', 5
d <<='pears', 8
print "d =", d
e = d
e <<='bananas', 1
print "e =", e
print "d =", d
d >>='pears'
print "d =", d
d <<={'blueberries': 2, 'watermelons': 315}
print "d =", d
print "e =", e
print "e['bananas'] =", e['bananas']
# result
d = {'apples': 5, 'pears': 8}
e = {'apples': 5, 'pears': 8, 'bananas': 1}
d = {'apples': 5, 'pears': 8}
d = {'apples': 5}
d = {'watermelons': 315, 'blueberries': 2, 'apples': 5}
e = {'apples': 5, 'pears': 8, 'bananas': 1}
e['bananas'] = 1
# e[0]=3
# would give:
# AttributeError: Use "value_dict<<='0', ..." instead of "d[0] = ..."
Please refer to the lvalue modification pattern discussed here: Python 2.7 - clean syntax for lvalue modification. The key observation is that str
and int
behave as values in Python (even though they're actually immutable objects under the hood). While you're observing that, please also observe that nothing is magically special about str
or int
. dict
can be used in much the same ways, and I can think of many cases where ValueDict
makes sense.

Approximate solution:
var c = document.getElementById("myCanvas");
var ctx = c.getContext("2d");
ctx.font = "100px Arial";
var txt = "Hello guys!"
var wt = ctx.measureText(txt).width;
var height = wt / txt.length;
This will be accurate result in monospaced font.
Means Not a Number. It is a common representation for an impossible numeric value in many programming languages.
I hope it will be helpful for others.

Heres how to do in Swift with closures:
func detectScreenShot(action: () -> ()) {
let mainQueue = NSOperationQueue.mainQueue()
NSNotificationCenter.defaultCenter().addObserverForName(UIApplicationUserDidTakeScreenshotNotification, object: nil, queue: mainQueue) { notification in
// executes after screenshot
action()
}
}
detectScreenShot { () -> () in
print("User took a screen shot")
}
Swift 4.2
func detectScreenShot(action: @escaping () -> ()) {
let mainQueue = OperationQueue.main
NotificationCenter.default.addObserver(forName: UIApplication.userDidTakeScreenshotNotification, object: nil, queue: mainQueue) { notification in
// executes after screenshot
action()
}
}
This is included as a standard function in:

Yes, there are a couple of differences, though in practical terms they're not usually big ones.
There's a fourth way, and as of ES2015 (ES6) there's two more. I've added the fourth way at the end, but inserted the ES2015 ways after #1 (you'll see why), so we have:
var a = 0; // 1
let a = 0; // 1.1 (new with ES2015)
const a = 0; // 1.2 (new with ES2015)
a = 0; // 2
window.a = 0; // 3
this.a = 0; // 4
#1 var a = 0;
This creates a global variable which is also a property of the global object, which we access as window
on browsers (or via this
a global scope, in non-strict code). Unlike some other properties, the property cannot be removed via delete
.
In specification terms, it creates an identifier binding on the object Environment Record for the global environment. That makes it a property of the global object because the global object is where identifier bindings for the global environment's object Environment Record are held. This is why the property is non-deletable: It's not just a simple property, it's an identifier binding.
The binding (variable) is defined before the first line of code runs (see "When var
happens" below).
Note that on IE8 and earlier, the property created on window
is not enumerable (doesn't show up in for..in
statements). In IE9, Chrome, Firefox, and Opera, it's enumerable.
#1.1 let a = 0;
This creates a global variable which is not a property of the global object. This is a new thing as of ES2015.
In specification terms, it creates an identifier binding on the declarative Environment Record for the global environment rather than the object Environment Record. The global environment is unique in having a split Environment Record, one for all the old stuff that goes on the global object (the object Environment Record) and another for all the new stuff (let
, const
, and the functions created by class
) that don't go on the global object.
The binding is created before any step-by-step code in its enclosing block is executed (in this case, before any global code runs), but it's not accessible in any way until the step-by-step execution reaches the let
statement. Once execution reaches the let
statement, the variable is accessible. (See "When let
and const
happen" below.)
#1.2 const a = 0;
Creates a global constant, which is not a property of the global object.
const
is exactly like let
except that you must provide an initializer (the = value
part), and you cannot change the value of the constant once it's created. Under the covers, it's exactly like let
but with a flag on the identifier binding saying its value cannot be changed. Using const
does three things for you:
#2 a = 0;
This creates a property on the global object implicitly. As it's a normal property, you can delete it. I'd recommend not doing this, it can be unclear to anyone reading your code later. If you use ES5's strict mode, doing this (assigning to a non-existent variable) is an error. It's one of several reasons to use strict mode.
And interestingly, again on IE8 and earlier, the property created not enumerable (doesn't show up in for..in
statements). That's odd, particularly given #3 below.
#3 window.a = 0;
This creates a property on the global object explicitly, using the window
global that refers to the global object (on browsers; some non-browser environments have an equivalent global variable, such as global
on NodeJS). As it's a normal property, you can delete it.
This property is enumerable, on IE8 and earlier, and on every other browser I've tried.
#4 this.a = 0;
Exactly like #3, except we're referencing the global object through this
instead of the global window
. This won't work in strict mode, though, because in strict mode global code, this
doesn't have a reference to the global object (it has the value undefined
instead).
What do I mean by "deleting" or "removing" a
? Exactly that: Removing the property (entirely) via the delete
keyword:
window.a = 0;
display("'a' in window? " + ('a' in window)); // displays "true"
delete window.a;
display("'a' in window? " + ('a' in window)); // displays "false"
delete
completely removes a property from an object. You can't do that with properties added to window
indirectly via var
, the delete
is either silently ignored or throws an exception (depending on the JavaScript implementation and whether you're in strict mode).
Warning: IE8 again (and presumably earlier, and IE9-IE11 in the broken "compatibility" mode): It won't let you delete properties of the window
object, even when you should be allowed to. Worse, it throws an exception when you try (try this experiment in IE8 and in other browsers). So when deleting from the window
object, you have to be defensive:
try {
delete window.prop;
}
catch (e) {
window.prop = undefined;
}
That tries to delete the property, and if an exception is thrown it does the next best thing and sets the property to undefined
.
This only applies to the window
object, and only (as far as I know) to IE8 and earlier (or IE9-IE11 in the broken "compatibility" mode). Other browsers are fine with deleting window
properties, subject to the rules above.
var
happensThe variables defined via the var
statement are created before any step-by-step code in the execution context is run, and so the property exists well before the var
statement.
This can be confusing, so let's take a look:
display("foo in window? " + ('foo' in window)); // displays "true"
display("window.foo = " + window.foo); // displays "undefined"
display("bar in window? " + ('bar' in window)); // displays "false"
display("window.bar = " + window.bar); // displays "undefined"
var foo = "f";
bar = "b";
display("foo in window? " + ('foo' in window)); // displays "true"
display("window.foo = " + window.foo); // displays "f"
display("bar in window? " + ('bar' in window)); // displays "true"
display("window.bar = " + window.bar); // displays "b"
Live example:
display("foo in window? " + ('foo' in window)); // displays "true"_x000D_
display("window.foo = " + window.foo); // displays "undefined"_x000D_
display("bar in window? " + ('bar' in window)); // displays "false"_x000D_
display("window.bar = " + window.bar); // displays "undefined"_x000D_
var foo = "f";_x000D_
bar = "b";_x000D_
display("foo in window? " + ('foo' in window)); // displays "true"_x000D_
display("window.foo = " + window.foo); // displays "f"_x000D_
display("bar in window? " + ('bar' in window)); // displays "true"_x000D_
display("window.bar = " + window.bar); // displays "b"_x000D_
_x000D_
function display(msg) {_x000D_
var p = document.createElement('p');_x000D_
p.innerHTML = msg;_x000D_
document.body.appendChild(p);_x000D_
}
_x000D_
As you can see, the symbol foo
is defined before the first line, but the symbol bar
isn't. Where the var foo = "f";
statement is, there are really two things: defining the symbol, which happens before the first line of code is run; and doing an assignment to that symbol, which happens where the line is in the step-by-step flow. This is known as "var
hoisting" because the var foo
part is moved ("hoisted") to the top of the scope, but the foo = "f"
part is left in its original location. (See Poor misunderstood var
on my anemic little blog.)
let
and const
happenlet
and const
are different from var
in a couple of ways. The way that's relevant to the question is that although the binding they define is created before any step-by-step code runs, it's not accessible until the let
or const
statement is reached.
So while this runs:
display(a); // undefined
var a = 0;
display(a); // 0
This throws an error:
display(a); // ReferenceError: a is not defined
let a = 0;
display(a);
The other two ways that let
and const
differ from var
, which aren't really relevant to the question, are:
var
always applies to the entire execution context (throughout global code, or throughout function code in the function where it appears), but let
and const
apply only within the block where they appear. That is, var
has function (or global) scope, but let
and const
have block scope.
Repeating var a
in the same context is harmless, but if you have let a
(or const a
), having another let a
or a const a
or a var a
is a syntax error.
Here's an example demonstrating that let
and const
take effect immediately in their block before any code within that block runs, but aren't accessible until the let
or const
statement:
var a = 0;
console.log(a);
if (true)
{
console.log(a); // ReferenceError: a is not defined
let a = 1;
console.log(a);
}
Note that the second console.log
fails, instead of accessing the a
from outside the block.
window
)The window
object gets very, very cluttered with properties. Whenever possible, strongly recommend not adding to the mess. Instead, wrap up your symbols in a little package and export at most one symbol to the window
object. (I frequently don't export any symbols to the window
object.) You can use a function to contain all of your code in order to contain your symbols, and that function can be anonymous if you like:
(function() {
var a = 0; // `a` is NOT a property of `window` now
function foo() {
alert(a); // Alerts "0", because `foo` can access `a`
}
})();
In that example, we define a function and have it executed right away (the ()
at the end).
A function used in this way is frequently called a scoping function. Functions defined within the scoping function can access variables defined in the scoping function because they're closures over that data (see: Closures are not complicated on my anemic little blog).
If you can't rename the original file, you could also use a symlink:
ln -s foo-bar.py foo_bar.py
Then you can just:
from foo_bar import *
Realizing the revision of the code I found the cause of why the reading method did not work for me. The problem was that one of the dependencies that my project used jersey 1.x. Update the version, adjust the client and it works.
I use the following maven dependency:
<dependency>
<groupId>org.glassfish.jersey.core</groupId>
<artifactId>jersey-client</artifactId>
<version>2.28</version>

atoi can do that for you
Example:
char string[] = "1234";
int sum = atoi( string );
printf("Sum = %d\n", sum ); // Outputs: Sum = 1234
I read an article a while ago that talked about locking down every class as much as possible. Make everything final and private unless you have an immediate need to expose some data or functionality to the outside world. It's always easy to expand the scope to be more permissible later on, but not the other way around. First consider making as many things as possible final
which will make choosing between private
and protected
much easier.
Now if you're left with a final class, then make everything private unless something is absolutely needed by the world - make that public.
If you're left with a class that does have subclass(es), then carefully examine every property and method. First consider if you even want to expose that property/method to subclasses. If you do, then consider whether a subclass can wreak havoc on your object if it messed up the property value or method implementation in the process of overriding. If it's possible, and you want to protect your class' property/method even from subclasses (sounds ironic, I know), then make it private. Otherwise make it protected.

Configuring $mail->SMTPAuth = true;

To be honest, you could fast concatenate two vectors by copy elements from two vectors into the other one or just only append one of two vectors!. It depends on your aim.
Method 1: Assign new vector with its size is the sum of two original vectors' size.
vector<int> concat_vector = vector<int>();
concat_vector.setcapacity(vector_A.size() + vector_B.size());
// Loop for copy elements in two vectors into concat_vector
Method 2: Append vector A by adding/inserting elements of vector B.
// Loop for insert elements of vector_B into vector_A with insert()
function: vector_A.insert(vector_A .end(), vector_B.cbegin(), vector_B.cend());

Why not use a PdfPTable

Create a fixed width table and use a float array to set the widths of the columns
PdfPTable table = new PdfPTable(10);
table.HorizontalAlignment = 0;
table.TotalWidth = 500f;
table.LockedWidth = true;
float[] widths = new float[] { 20f, 60f, 60f, 30f, 50f, 80f, 50f, 50f, 50f, 50f };
table.SetWidths(widths);
addCell(table, "SER.\nNO.", 2);

This will take your tableview to the first row.
As other have already suggested it is likely you are getting a NullReferenceException
which can be avoided by first checking to see if the reference is null
. However, you need to ask yourself whether that check is actually warranted. Would you be doing it because the reference really might be null
and it being null
has a special meaning in your code? Or would you be doing it to cover up a bug? The nature of the question leads me to believe it would be the latter. In which case you really need to examine the code in depth and figure out why that reference did not get initialized properly in the first place.
One thing I've used with good results is the following (I don't know if its mentioned already because I can't remember its name).
You precompute a table T with a random number for each character in your key's alphabet [0,255]. You hash your key 'k0 k1 k2 ... kN' by taking T[k0] xor T[k1] xor ... xor T[kN]. You can easily show that this is as random as your random number generator and its computationally very feasible and if you really run into a very bad instance with lots of collisions you can just repeat the whole thing using a fresh batch of random numbers.
First question:
Use the Intent to call another Activity. In the Manifest, you should add
<activity android:name="ListViewImage"></activity>
<activity android:name="com.company.listview.ListViewImage">
</activity>
And in your current activity,
btListe = (ImageButton)findViewById(R.id.Button_Liste);
btListe.setOnClickListener(new OnClickListener()
{ public void onClick(View v)
{
intent = new Intent(main.this, ListViewImage.class);
startActivity(intent);
finish();
}
});
Second question:
sendButton.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
String valueString = editValue.getText().toString();
long value;
if (valueString != null) {
value = Long.parseLong(valueString);
}
else {
value = 0;
}
Bundle sendBundle = new Bundle();
sendBundle.putLong("value", value);
Intent i = new Intent(Activity1.this, Activity2.class);
i.putExtras(sendBundle);
startActivity(i);
finish();
}
});
and in Activity2:
Bundle receiveBundle = this.getIntent().getExtras();
final long receiveValue = receiveBundle.getLong("value");
receiveValueEdit.setText(String.valueOf(receiveValue));
callReceiverButton.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
Intent i = new Intent(Activity2.this, Receiver.class);
i.putExtra("new value", receiveValue - 10);
}
});
If relative paths are what you want you can just use the -Name
flag.

I ported the get

res.json(BlogPosts.get());
});
Correct:
//server.js
app.use('/blog-posts', blogPostsRouter);
//routers/blogPostsRouter.js
router.get('/', (req, res) => {

Took a while to spot, as the error had me checking syntax where I might have been wrapping an argument in an object or where I missed the module.exports = router;

Getting updatedb to work in cron on Cygwin -- debugging steps
1) Make sure cron is installed.
a) Type 'cron' tab tab and look for completion help.
You should see crontab.exe, cron-config, etc. If not install cron using setup.
2) Run cron-config. Be sure to read all the ways to diagnose cron.
3) Run crontab -e
a) Create a test entry of something simple, e.g.,
"* * * * * echo $HOME >> /tmp/mycron.log" and save it.
4) cat /tmp/mycron.log. Does it show cron environment variable HOME
every minute?
5) Is HOME correct? By default mine was /home/myusername; not what I wanted.
So, I added the entry
"HOME='/cygdrive/c/documents and settings/myusername'" to crontab.
6) Once assured the test entry works I moved on to 'updatedb' by
adding an entry in crontab.
7) Since updatedb is a script, errors of sed and find showed up in
my cron.log file. In the error line, the absolute path of sed referenced
an old version of sed.exe and not the one in /usr/bin. I tried changing my
cron PATH environment variable but because it was so long crontab
considered the (otherwise valid) change to be an error. I tried an
explicit much-shorter PATH command, including what I thought were the essential
WINDOWS paths but my cron.log file was empty. Eventually I left PATH alone and
replaced the old sed.exe in the other path with sed.exe from /usr/bin.
After that updatedb ran to completion. To reduce the number of
permission error lines I eventually ended up with this:
"# Run updatedb at 2:10am once per day skipping Sat and Sun'
"10 2 * * 1-5 /usr/bin/updatedb --localpaths='/cygdrive/c' --prunepaths='/cygdrive/c/WINDOWS'"
Notes: I ran cron-config several times throughout this process
to restart the cygwin cron daemon.
You can store a reference id to any setInterval or setTimeout. Like this:
var loop = setInterval(func, 30);
// some time later clear the interval
clearInterval(loop);
To do this without a "global" variable you can add a local variable to the function itself. Ex:
$(window).resize(function() {
clearTimeout(this.id);
this.id = setTimeout(doneResizing, 500);
});
function doneResizing(){
$("body").append("<br/>done!");
}
Why not do it?
var result= ctx.table.Where(x => x.UserName == "Value").FirstOrDefault();
if(result?.field == value)
{
// Match!
}
The idiom is to use the bitwise or-equal operator to set bits:
flags |= 0x04;
To clear a bit, the idiom is to use bitwise and with negation:
flags &= ~0x04;
Sometimes you have an offset that identifies your bit, and then the idiom is to use these combined with left-shift:
flags |= 1 << offset;
flags &= ~(1 << offset);
For beginners like me that will stumble upon this tiny problem, in a simple line, with sample conversion to int:
int totalDays = Convert.ToInt32((DateTime.UtcNow.Date - myDateTime.Date).TotalDays);
This calculates the total days from today (DateTime.UtcNow.Date) to a desired date (myDateTime.Date).
If myDateTime is yesterday, or older date than today, this will give a positive (+) integer result.
On the other side, if the myDateTime is tomorrow or on the future date, this will give a negative (-) integer result due to rules of addition.
Happy coding! ^_^

Named tuples are basically easy-to-create, lightweight object types. Named tuple instances can be referenced using object-like variable dereferencing or the standard tuple syntax. They can be used similarly to struct
or other common record types, except that they are immutable. They were added in Python 2.6 and Python 3.0, although there is a recipe for implementation in Python 2.4.
For example, it is common to represent a point as a tuple (x, y)
. This leads to code like the following:
pt1 = (1.0, 5.0)
pt2 = (2.5, 1.5)
from math import sqrt
line_length = sqrt((pt1[0]-pt2[0])**2 + (pt1[1]-pt2[1])**2)
Using a named tuple it becomes more readable:
from collections import namedtuple
Point = namedtuple('Point', 'x y')
pt1 = Point(1.0, 5.0)
pt2 = Point(2.5, 1.5)
from math import sqrt
line_length = sqrt((pt1.x-pt2.x)**2 + (pt1.y-pt2.y)**2)
However, named tuples are still backwards compatible with normal tuples, so the following will still work:
Point = namedtuple('Point', 'x y')
pt1 = Point(1.0, 5.0)
pt2 = Point(2.5, 1.5)
from math import sqrt
# use index referencing
line_length = sqrt((pt1[0]-pt2[0])**2 + (pt1[1]-pt2[1])**2)
# use tuple unpacking
x1, y1 = pt1
Thus, you should use named tuples instead of tuples anywhere you think object notation will make your code more pythonic and more easily readable. I personally have started using them to represent very simple value types, particularly when passing them as parameters to functions. It makes the functions more readable, without seeing the context of the tuple packing.
Furthermore, you can also replace ordinary immutable classes that have no functions, only fields with them. You can even use your named tuple types as base classes:
class Point(namedtuple('Point', 'x y')):
[...]
However, as with tuples, attributes in named tuples are immutable:
>>> Point = namedtuple('Point', 'x y')
>>> pt1 = Point(1.0, 5.0)
>>> pt1.x = 2.0

If you want to be able change the values, you need another type. There is a handy recipe for mutable recordtypes which allow you to set new values to attributes.
>>> from rcdtype import *
>>> Point = recordtype('Point', 'x y')
>>> pt1 = Point(1.0, 5.0)
>>> pt1 = Point(1.0, 5.0)
>>> pt1.x = 2.0
>>> print(pt1[0])
2.0
I am not aware of any form of "named list" that lets you add new fields, however. You may just want to use a dictionary in this situation. Named tuples can be converted to dictionaries using pt1._asdict()
which returns {'x': 1.0, 'y': 5.0}
and can be operated upon with all the usual dictionary functions.
As already noted, you should check the documentation for more information from which these examples were constructed.
((DefaultTableModel)jTable3.getModel()).setNumRows(0); // delet all table row
Try This:
Within your component, you can define an array of number (ES6) as described below:
export class SampleComponent {
constructor() {
this.numbers = Array(5).fill(0).map((x,i)=>i);
}
}
See this link for the array creation: Tersest way to create an array of integers from 1..20 in JavaScript.
You can then iterate over this array with ngFor
:
@View({
template: `
<ul>
<li *ngFor="let number of numbers">{{number}}</li>
</ul>
`
})
export class SampleComponent {
(...)
}
Or shortly:
@View({
template: `
<ul>
<li *ngFor="let number of [0,1,2,3,4]">{{number}}</li>
</ul>
`
})
export class SampleComponent {
(...)
}
Hope it helps you, Thierry
Edit: Fixed the fill statement and template syntax.
In the current version of RestSharp (105.2.3.0) you can add a JSON object to the request body with:
request.AddJsonBody(new { A = "foo", B = "bar" });
This method sets content type to application/json and serializes the object to a JSON string.
Here is my cover fill solution (similar to background-size: cover, but it supports old IE browser)
<div class="imgContainer" style="height:100px; width:500px; overflow:hidden; background-color: black">
<img src="http://dev.isaacsonwebdevelopment.com/sites/development/files/views-slideshow-settings-jquery-cycle-custom-options-message.png" id="imgCat">
</div>
<script src="http://ajax.aspnetcdn.com/ajax/jQuery/jquery-1.11.3.min.js"></script>
<script>
$(window).load(function() {
var heightRate =$("#imgCat").height() / $("#imgCat").parent(".imgContainer").height();
var widthRate = $("#imgCat").width() / $("#imgCat").parent(".imgContainer").width();
if (window.console) {
console.log($("#imgCat").height());
console.log(heightRate);
console.log(widthRate);
console.log(heightRate > widthRate);
}
if (heightRate <= widthRate) {
$("#imgCat").height($("#imgCat").parent(".imgContainer").height());
} else {
$("#imgCat").width($("#imgCat").parent(".imgContainer").width());
}
});
</script>
The url
template tag will pass the parameter as a string and not as a function reference to reverse()
. The simplest way to get this working is adding a name
to the view:
url(r'^/logout/' , logout_view, name='logout_view')
Another possibility is to use the textwrap module. This also avoids the problem of "string just sitting in the middle of nowhere" as mentioned in the question.
import textwrap
mystr = """\
Why, hello there
wonderful stackoverfow people"""
print (textwrap.fill(textwrap.dedent(mystr)))
Well for me the problem occurred when I dragged a prototype cell from the menu into the table view. So I deleted that and just set prototype cell to 1 in table view inspector properties
I had a similar problem but I was trying to restore from lower to higher version (correct). The problem was however in insufficient rights. When I logged in with "Windows Authentication" I was able to restore the database.
In my apache error log, I saw:
[Tue Feb 16 14:55:02 2010] [notice] child pid 9985 exit signal File size limit exceeded (25)
So I, removed all the contents of my largest log file 2.1GB /var/log/system.log. Now everything works.
There is no such thing as associative array in Java. Its closest relative is a Map
, which is strongly typed, however has less elegant syntax/API.
This is the closest you can get based on your example:
Map<Integer, Map<String, String>> arr =
org.apache.commons.collections.map.LazyMap.decorate(
new HashMap(), new InstantiateFactory(HashMap.class));
//$arr[0]['name'] = 'demo';
arr.get(0).put("name", "demo");
System.out.println(arr.get(0).get("name"));
System.out.println(arr.get(1).get("name")); //yields null
Many of the answers seem to me to be ignoring the stated requirements:
These two together rule out a LINQ sequence of bytes - anything with yield
is going to make it impossible to get the final size without iterating through the whole sequence.
If those aren't the real requirements of course, LINQ could be a perfectly good solution (or the IList<T>
implementation). However, I'll assume that Superdumbell knows what he wants.
(EDIT: I've just had another thought. There's a big semantic difference between making a copy of the arrays and reading them lazily. Consider what happens if you change the data in one of the "source" arrays after calling the Combine
(or whatever) method but before using the result - with lazy evaluation, that change will be visible. With an immediate copy, it won't. Different situations will call for different behaviour - just something to be aware of.)
Here are my proposed methods - which are very similar to those contained in some of the other answers, certainly :)
public static byte[] Combine(byte[] first, byte[] second)
{
byte[] ret = new byte[first.Length + second.Length];
Buffer.BlockCopy(first, 0, ret, 0, first.Length);
Buffer.BlockCopy(second, 0, ret, first.Length, second.Length);
return ret;
}
public static byte[] Combine(byte[] first, byte[] second, byte[] third)
{
byte[] ret = new byte[first.Length + second.Length + third.Length];
Buffer.BlockCopy(first, 0, ret, 0, first.Length);
Buffer.BlockCopy(second, 0, ret, first.Length, second.Length);
Buffer.BlockCopy(third, 0, ret, first.Length + second.Length,
third.Length);
return ret;
}
public static byte[] Combine(params byte[][] arrays)
{
byte[] ret = new byte[arrays.Sum(x => x.Length)];
int offset = 0;
foreach (byte[] data in arrays)
{
Buffer.BlockCopy(data, 0, ret, offset, data.Length);
offset += data.Length;
}
return ret;
}
Of course the "params" version requires creating an array of the byte arrays first, which introduces extra inefficiency.
if var is NULL then
var :=5;
end if;
Try this test:
any(substring in string for substring in substring_list)
It will return True
if any of the substrings in substring_list
is contained in string
.
Note that there is a Python analogue of Marc Gravell's answer in the linked question:
from itertools import imap
any(imap(string.__contains__, substring_list))
In Python 3, you can use map
directly instead:
any(map(string.__contains__, substring_list))
Probably the above version using a generator expression is more clear though.
The asterisk (*) means "zero or more of the previous item".
If you want to match any single character use
sed -i 's/string-./string-0/g' file.txt
If you want to match any string (i.e. any single character zero or more times) use
sed -i 's/string-.*/string-0/g' file.txt
when .slice() is called normally, this is an Array, and then it just iterates over that Array, and does its work.
//ARGUMENTS
function func(){
console.log(arguments);//[1, 2, 3, 4]
//var arrArguments = arguments.slice();//Uncaught TypeError: undefined is not a function
var arrArguments = [].slice.call(arguments);//cp array with explicity THIS
arrArguments.push('new');
console.log(arrArguments)
}
func(1,2,3,4)//[1, 2, 3, 4, "new"]

Or you can use

With C++11, the above would be possible for basic types as
class Foo {
public:
static constexpr int MEMBER = 1;
};
The constexpr
part creates a static expression as opposed to a static variable - and that behaves just like an extremely simple inline method definition. The approach proved a bit wobbly with C-string constexprs inside template classes, though.
The answers given here already may work in limited situations, but are certainly not the best way to go about it. Don't reinvent the wheel. The File System Object in the Microsoft Scripting Runtime library already has a method to do exactly this. It's called GetBaseName. It handles periods in the file name as is.
Public Sub Test()
Dim fso As New Scripting.FileSystemObject
Debug.Print fso.GetBaseName(ActiveWorkbook.Name)
End Sub
Public Sub Test2()
Dim fso As New Scripting.FileSystemObject
Debug.Print fso.GetBaseName("MyFile.something.txt")
End Sub
Instructions for adding a reference to the Scripting Library
Although this question was more specifically about IP addresses in Subject Alt. Names, the commands are similar (using DNS
entries for a host name and IP
entries for IP addresses).
To quote myself:
If you're using
keytool
, as of Java 7, keytool has an option to include a Subject Alternative Name (see the table in the documentation for -ext): you could use -ext san=dns:www.example.com or -ext san=ip:10.0.0.1
Note that you only need Java 7's keytool
to use this command. Once you've prepared your keystore, it should work with previous versions of Java.
(The rest of this answer also mentions how to do this with OpenSSL, but it doesn't seem to be what you're using.)
Did you try:

To remove specific key and element from hashmap use
hashmap.remove(key)
full source code is like
import java.util.HashMap;
public class RemoveMapping {
public static void main(String a[]){
HashMap hashMap = new HashMap();
hashMap.put(1, "One");
hashMap.put(2, "Two");
hashMap.put(3, "Three");
System.out.println("Original HashMap : "+hashMap);
hashMap.remove(3);
System.out.println("Changed HashMap : "+hashMap);
}
}
Thanks for help. This is the solution: I created the subview and i add a gesture to remove it
@IBAction func infoView(sender: UIButton) {
var testView: UIView = UIView(frame: CGRectMake(0, 0, 320, 568))
testView.backgroundColor = UIColor.blueColor()
testView.alpha = 0.5
testView.tag = 100
testView.userInteractionEnabled = true
self.view.addSubview(testView)
let aSelector : Selector = "removeSubview"
let tapGesture = UITapGestureRecognizer(target:self, action: aSelector)
testView.addGestureRecognizer(tapGesture)
}
func removeSubview(){
println("Start remove sibview")
if let viewWithTag = self.view.viewWithTag(100) {
viewWithTag.removeFromSuperview()
}else{
println("No!")
}
}
Update:
Swift 3+
@IBAction func infoView(sender: UIButton) {
let testView: UIView = UIView(frame: CGRect(x: 0, y: 0, width: 320, height: 568))
testView.backgroundColor = .blue
testView.alpha = 0.5
testView.tag = 100
testView.isUserInteractionEnabled = true
self.view.addSubview(testView)
let aSelector : Selector = #selector(GasMapViewController.removeSubview)
let tapGesture = UITapGestureRecognizer(target:self, action: aSelector)
testView.addGestureRecognizer(tapGesture)
}
func removeSubview(){
print("Start remove sibview")
if let viewWithTag = self.view.viewWithTag(100) {
viewWithTag.removeFromSuperview()
}else{
print("No!")
}
}
Looks like you are missing the printer name, driver, and port - in that order. Your final command should resemble:
AcroRd32.exe /t <file.pdf> <printer_name> <printer_driver> <printer_port>
For example:
"C:\Program Files (x86)\Adobe\Reader 11.0\Reader\AcroRd32.exe" /t "C:\Folder\File.pdf" "Brother MFC-7820N USB Printer" "Brother MFC-7820N USB Printer" "IP_192.168.10.110"
Note: To find the printer information, right click your printer and choose properties. In my case shown above, the printer name and driver name matched - but your information may differ.
Definitive answer: import os
and use os.path
. do not import os.path
directly.
From the documentation of the module itself:
>>> import os
>>> help(os.path)
...
Instead of importing this module directly, import os and refer to
this module as os.path. The "os.path" name is an alias for this
module on Posix systems; on other systems (e.g. Mac, Windows),
os.path provides the same operations in a manner specific to that
platform, and is an alias to another module (e.g. macpath, ntpath).
