Any chance that you changed the name of your table view from "tableView" to "myTableView" at some point?
Here is a Ray Wenderlich tutorial that shows you how to use AutoLayout to dynamically size UITableViewCell
s. I would think it would be the same for UICollectionViewCell
.
Basically, though, you end up dequeueing and configuring a prototype cell and grabbing its height. After reading this article, I decided to NOT implement this method and just write some clear, explicit sizing code.
Here's what I consider the "secret sauce" for the entire article:
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath {
return [self heightForBasicCellAtIndexPath:indexPath];
}
- (CGFloat)heightForBasicCellAtIndexPath:(NSIndexPath *)indexPath {
static RWBasicCell *sizingCell = nil;
static dispatch_once_t onceToken;
dispatch_once(&onceToken, ^{
sizingCell = [self.tableView dequeueReusableCellWithIdentifier:RWBasicCellIdentifier];
});
[self configureBasicCell:sizingCell atIndexPath:indexPath];
return [self calculateHeightForConfiguredSizingCell:sizingCell];
}
- (CGFloat)calculateHeightForConfiguredSizingCell:(UITableViewCell *)sizingCell {
[sizingCell setNeedsLayout];
[sizingCell layoutIfNeeded];
CGSize size = [sizingCell.contentView systemLayoutSizeFittingSize:UILayoutFittingCompressedSize];
return size.height + 1.0f; // Add 1.0f for the cell separator height
}
Once you've done that, code like the following will get you going:
// ViewController.m
#import "ViewController.h"
#import "CollectionViewCell.h"
@interface ViewController () <UICollectionViewDataSource, UICollectionViewDelegate, UICollectionViewDelegateFlowLayout> {
}
@property (weak, nonatomic) IBOutlet CollectionViewCell *cell;
@property (weak, nonatomic) IBOutlet UICollectionView *collectionView;
@end
@implementation ViewController
- (void)viewDidLoad {
[super viewDidLoad];
self.view.backgroundColor = [UIColor lightGrayColor];
[self.collectionView registerNib:[UINib nibWithNibName:@"CollectionViewCell" bundle:nil] forCellWithReuseIdentifier:@"cell"];
}
- (void)viewDidAppear:(BOOL)animated {
[super viewDidAppear:animated];
NSLog(@"viewDidAppear...");
}
- (NSInteger)numberOfSectionsInCollectionView:(UICollectionView *)collectionView {
return 1;
}
- (NSInteger)collectionView:(UICollectionView *)collectionView numberOfItemsInSection:(NSInteger)section {
return 50;
}
- (CGFloat)collectionView:(UICollectionView *)collectionView layout:(UICollectionViewLayout *)collectionViewLayout minimumInteritemSpacingForSectionAtIndex:(NSInteger)section {
return 10.0f;
}
- (CGFloat)collectionView:(UICollectionView *)collectionView layout:(UICollectionViewLayout *)collectionViewLayout minimumLineSpacingForSectionAtIndex:(NSInteger)section {
return 10.0f;
}
- (CGSize)collectionView:(UICollectionView *)collectionView layout:(UICollectionViewLayout *)collectionViewLayout sizeForItemAtIndexPath:(NSIndexPath *)indexPath {
return [self sizingForRowAtIndexPath:indexPath];
}
- (CGSize)sizingForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *title = @"This is a long title that will cause some wrapping to occur. This is a long title that will cause some wrapping to occur.";
static NSString *subtitle = @"This is a long subtitle that will cause some wrapping to occur. This is a long subtitle that will cause some wrapping to occur.";
static NSString *buttonTitle = @"This is a really long button title that will cause some wrapping to occur.";
static CollectionViewCell *sizingCell = nil;
static dispatch_once_t onceToken;
dispatch_once(&onceToken, ^{
sizingCell = [[NSBundle mainBundle] loadNibNamed:@"CollectionViewCell" owner:self options:nil][0];
});
[sizingCell configureWithTitle:title subtitle:[NSString stringWithFormat:@"%@: Number %d.", subtitle, (int)indexPath.row] buttonTitle:buttonTitle];
[sizingCell setNeedsLayout];
[sizingCell layoutIfNeeded];
CGSize cellSize = [sizingCell.contentView systemLayoutSizeFittingSize:UILayoutFittingCompressedSize];
NSLog(@"cellSize: %@", NSStringFromCGSize(cellSize));
return cellSize;
}
- (UICollectionViewCell *)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath {
static NSString *title = @"This is a long title that will cause some wrapping to occur. This is a long title that will cause some wrapping to occur.";
static NSString *subtitle = @"This is a long subtitle that will cause some wrapping to occur. This is a long subtitle that will cause some wrapping to occur.";
static NSString *buttonTitle = @"This is a really long button title that will cause some wrapping to occur.";
CollectionViewCell *cell = [collectionView dequeueReusableCellWithReuseIdentifier:@"cell" forIndexPath:indexPath];
[cell configureWithTitle:title subtitle:[NSString stringWithFormat:@"%@: Number %d.", subtitle, (int)indexPath.row] buttonTitle:buttonTitle];
return cell;
}
@end
The code above (along with a very basic UICollectionViewCell
subclass and associated XIB) gives me this:
In my case if you are using UITableView
do not forget to add UITableViewDelegate and UITableViewDataSource next to viewcontroller like this. class MenuController: UIViewController, UITableViewDelegate, UITableViewDataSource
When converting old projects (written in Swift 2.3) to Swift 3 it needs adding these keywords.
Came across this issue in Xcode 11, fix was changing the Minimum Deployment Target from 10.0 to 11.0, hope this helps someone :)
You can install SideBarEnhancements plugin, which among other things will give you ability to open file in browser just by clicking F12.
To open exactly in Chrome, you will need to fix up “Side Bar.sublime-settings” file and set "default_browser"
to be "chrome"
.
I also recommend to learn this video tutorial on Sublime Text 2.
The CSS :first-child
selector allows you to target an element that is the first child element within its parent.
element:first-child { style_properties }
table:first-child { style_properties }
I basically do like this, create new element and attach that to <head>
var x = document.createElement('script');
x.src = 'http://example.com/test.js';
document.getElementsByTagName("head")[0].appendChild(x);
You may also use onload
event to each script you attach, but please test it out, I am not so sure it works cross-browser or not.
x.onload=callback_function;
1) on your mac type
nano /usr/bin/wget
2) paste the following in
#!/bin/bash
curl -L $1 -o $2
3) close then make it executable
chmod 777 /usr/bin/wget
That's it.
If you did everything right, just give the permission home directory like:
sudo chmod o+x $HOME
then
sudo systemctl restart apache2
Into Preferences > Settings - Users

Those classes are common extension points for Java UI designs. First off, realize that they don't necessarily have much to do with each other directly, so trying to find a relationship between them might be counterproductive.
JApplet - A base class that let's you write code that will run within the context of a browser, like for an interactive web page. This is cool and all but it brings limitations which is the price for it playing nice in the real world. Normally JApplet is used when you want to have your own UI in a web page. I've always wondered why people don't take advantage of applets to store state for a session so no database or cookies are needed.
JComponent - A base class for objects which intend to interact with Swing.
JFrame - Used to represent the stuff a window should have. This includes borders (resizeable y/n?), titlebar (App name or other message), controls (minimize/maximize allowed?), and event handlers for various system events like 'window close' (permit app to exit yet?).
JPanel - Generic class used to gather other elements together. This is more important with working with the visual layout or one of the provided layout managers e.g. gridbaglayout, etc. For example, you have a textbox that is bigger then the area you have reserved. Put the textbox in a scrolling pane and put that pane into a JPanel. Then when you place the JPanel, it will be more manageable in terms of layout.
I've done this before. I had a pdf that I generated with fpdf, and I needed to add on a variable amount of PDFs to it.
So I already had an fpdf object and page set up (http://www.fpdf.org/) And I used fpdi to import the files (http://www.setasign.de/products/pdf-php-solutions/fpdi/) FDPI is added by extending the PDF class:
class PDF extends FPDI
{
}
$pdffile = "Filename.pdf";
$pagecount = $pdf->setSourceFile($pdffile);
for($i=0; $i<$pagecount; $i++){
$pdf->AddPage();
$tplidx = $pdf->importPage($i+1, '/MediaBox');
$pdf->useTemplate($tplidx, 10, 10, 200);
}
This basically makes each pdf into an image to put into your other pdf. It worked amazingly well for what I needed it for.
I got this issue when I used an ajax call to retrieve data from the database. When the controller returned the array it converted it to a boolean. The problem was that I had "invalid characters" like ú (u with accent).
I know it's very late to answer the question but with Auto-Property you can do something like that:
public static Singleton Instance { get; } = new Singleton();
Where Singleton
is you class and can be via, in this case the readonly property Instance
.
Directly from the node.js tag wiki, make sure watch some of the talk videos linked there to get a better idea.
Node.js is an event based, asynchronous I/O framework that uses Google's V8 JavaScript Engine.
Node.js - or just Node as it's commonly called - is used for developing applications that make heavy use of the ability to run JavaScript both on the client, as well as on server side and therefore benefit from the re-usability of code and the lack of context switching.
It's also possible to use matured JavaScript frameworks like YUI and jQuery for server side DOM manipulation.
To ease the development of complex JavaScript further, Node.js supports the CommonJS standard that allows for modularized development and the distribution of software in packages via the Node Package Manager.
Considering existing answers, I've copy-pasted and enhanced source code of Integer.parseInt
to do the job, and my solution
Ints.tryParse()
),int[]
, Box
, OptionalInt
),CharSequence
or a part of it instead of a whole String
,Integer.parseInt
can, i.e. [2,36],The only downside is that there's no difference between toIntOfDefault("-1", -1)
and toIntOrDefault("oops", -1)
.

}
public static int toIntOrDefault(CharSequence s, int start, int endExclusive, int def) {
boundsCheck(start, endExclusive, s.length());
return toIntOrDefault0(s, start, endExclusive, 10, def);
}
public static int toIntOrDefault(CharSequence s, int start, int endExclusive, int radix, int def) {

limit = Integer.MIN_VALUE;
} else if (firstChar != '+') {
return def;
}
start++;
// Cannot have lone "+" or "-"
if (start == endExclusive) return def;
}
int multmin = limit / radix;
int result = 0;
while (start < endExclusive) {
// Accumulating negatively avoids surprises near MAX_VALUE
int digit = Character.digit(s.charAt(start++), radix);
if (digit < 0 || result < multmin) return def;
result *= radix;
if (result < limit + digit) return def;
result -= digit;
}
return negative ? result : -result;
}
private static void radixCheck(int radix) {

It is probably that your library is not linked to project properly or that you have older google-play-services library version so conflict appears and Eclipse got stupid.. :S
No you don't need to add anything in integers.xml. When you link properly Google-play-services library to your project reference android:value="@integer/google_play_services_version"
will be found and you are ready to go. When you add library to your project just do one more clean so funny Eclipse environment sweep-out things properly.
If you hardcode somewhere this number when next play version come you would need to update it. And if you forget that, you will spend time again looking for bug.. :S
Hope it helped. ;)
I got the same issue since I was referring old- Microsoft.EntityFrameworkCore.Tools.DotNet
<DotNetCliToolReference Include="Microsoft.EntityFrameworkCore.Tools.DotNet" Version="1.0.0" />
After upgrading to the newer version it got resolved
Late to the game but you can also use the janitor
package. This function will remove columns which are all NA, and can be changed to remove rows that are all NA as well.
df <- janitor::remove_empty(df, which = "cols")
You can use sqlcmd to run a backup, or any other T-SQL script. You can find the detailed instructions and examples on various useful sqlcmd switches in this article: Working with the SQL Server command line (sqlcmd)
I found a simple way to fix that problem. At binding datagridview you've just done: datagridview.DataSource = dataSetName.Tables["TableName"];
If you code like:
datagridview.DataSource = dataSetName;
datagridview.DataMember = "TableName";
the datagridview will never load data again when filtering.
I would probably go with Joran's suggestion of replacing 0's with NAs and then using the built in functions you mentioned. If you can't/don't want to do that, one approach is to use any()
to find rows that contain 0's and subset those out:
set.seed(42)
#Fake data
x <- data.frame(a = sample(0:2, 5, TRUE), b = sample(0:2, 5, TRUE))
> x
a b
1 2 1
2 2 2
3 0 0
4 2 1
5 1 2
#Subset out any rows with a 0 in them
#Note the negation with ! around the apply function
x[!(apply(x, 1, function(y) any(y == 0))),]
a b
1 2 1
2 2 2
4 2 1
5 1 2
To implement Joran's method, something like this should get you started:
x[x==0] <- NA
Tailor this code however you like to fit your needs, you can select text? in the paragraph to be what font or style you need!:
<head>
<style>
p{ color:#ff0000;font-family: "Times New Roman", Times, serif;}
font{color:#000fff;background:#000000;font-size:225%;}
b{color:green;}
</style>
</head>
<body>
<p>This is your <b>text. <font>Type</font></strong></b>what you like</p>
</body>
Simply set height of the select tag
select{
height: 30px;
max-height: 30px;
}
Hi try this it will create directory + file inside it
File mediaDir = new File("/sdcard/download/media");
if (!mediaDir.exists()){
mediaDir.mkdir();
}
File resolveMeSDCard = new File("/sdcard/download/media/hello_file.txt");
resolveMeSDCard.createNewFile();
FileOutputStream fos = new FileOutputStream(resolveMeSDCard);
fos.write(string.getBytes());
fos.close();
System.out.println("Your file has been written");
What the error is telling, is that you can't convert an entire list into an integer. You could get an index from the list and convert that into an integer:
x = ["0", "1", "2"]
y = int(x[0]) #accessing the zeroth element
If you're trying to convert a whole list into an integer, you are going to have to convert the list into a string first:
x = ["0", "1", "2"]
y = ''.join(x) # converting list into string
z = int(y)
If your list elements are not strings, you'll have to convert them to strings before using str.join
:
x = [0, 1, 2]
y = ''.join(map(str, x))
z = int(y)
Also, as stated above, make sure that you're not returning a nested list.
I had the same problem with my Windows 8. The Android/SDK USB driver was installed correctly, but I forgot to install the USB driver from my phone. After installing the phone USB driver ADB works fine.
I hope this will help.
To achieve the 360 degree rotation, here is the Working Solution.
The HTML:
<img class="image" src="your-image.png">
The CSS:
.image {
overflow: hidden;
transition-duration: 0.8s;
transition-property: transform;
}
.image:hover {
transform: rotate(360deg);
-webkit-transform: rotate(360deg);
}
You have to hover on the image and you will get the 360 degree rotation effect.
PS: Add a -webkit-
extension for it to work on chrome and other webkit browers. You can check the updated fiddle for webkit HERE
I had a bootstrap + rails project, and dropdown worked fine. They stopped to works after an update...
This is the solution that fixed the problem, add the following to .js file:
$(document).ready(function() {
$(".dropdown-toggle").dropdown();
});
You can add the style attribute or you can add a definition for the input tag in a css file.
Option 1: adding the style attribute
<input type="text" class="form-control" id="ex1" style="width: 100px;">
Option 2: definition in css
input{
width: 100px
}
You can change the 100px in auto
I hope I could help.
Not entirely related to the question, but if the field injection is null, the constructor based injection will still work fine.
private OrderingClient orderingClient;
private Sales2Client sales2Client;

Here is a little combination of @Regexident Option 1 and @Garett answers, to get a powerful string cutter between a prefix and suffix, with MORE...ANDMORE words on it.
NSString *haystack = @"MOREvalue:hello World:valueANDMORE";
NSString *prefix = @"value:";
NSString *suffix = @":value";
NSRange prefixRange = [haystack rangeOfString:prefix];
NSRange suffixRange = [[haystack substringFromIndex:prefixRange.location+prefixRange.length] rangeOfString:suffix];
NSRange needleRange = NSMakeRange(prefixRange.location+prefix.length, suffixRange.location);
NSString *needle = [haystack substringWithRange:needleRange];
NSLog(@"needle: %@", needle);
In my case it was a result of my adding a new dependency to my pom.xml
file.
The new dependency depended on an old version of a library (2.5). That same library was required by another library in my pom.xml
, but it required version 3.0.
For some reason, when Maven encounters these conflicts it simply omits the most recent version. In Eclipse when viewing pom.xml
you can select the "dependency hierarchy" tab at the bottom to see how dependencies are resolved. Here you will find if the library (and thus class) in question has been omitted for this reason.
In my case it was as simple as locking down the newer version. You can do so by right-clicking the entry - there is an option to lock it down in the context menu.
you can also quote string
''+document.location+''.substring(2,3);
mysql servers are usually configured to listen only to localhost (127.0.0.1), where they are used by web applications.
If that is your case but you have SSH access to your server, you can create an ssh tunnel and connect through that.
On your local machine, create the tunnel.
ssh -L 3307:127.0.0.1:3306 -N $user@$remote_host
(this example uses local port 3307, in case you also have mysql running on your local machine and using the standard port 3306)
Now you should be ale to connect with
mysql -u $user -p -h 127.0.0.1 -P 3307
You should not need to access Maven-specific files to get the version information of any given library/class.
You can simply use getClass().getPackage().getImplementationVersion()
to get the version information that is stored in a .jar-files MANIFEST.MF
. Luckily Maven is smart enough Unfortunately Maven does not write the correct information to the manifest as well by default!
Instead one has to modify the <archive>
configuration element of the maven-jar-plugin
to set addDefaultImplementationEntries
and addDefaultSpecificationEntries
to true
, like this:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-jar-plugin</artifactId>
<configuration>
<archive>
<manifest>
<addDefaultImplementationEntries>true</addDefaultImplementationEntries>
<addDefaultSpecificationEntries>true</addDefaultSpecificationEntries>
</manifest>
</archive>
</configuration>
</plugin>
Ideally this configuration should be put into the company pom
or another base-pom.
Detailed documentation of the <archive>
element can be found in the Maven Archive documentation.
To export the output to file on a continuous basis (here every five seconds) and save to a CSV file with the Unix date as the filename:
while ($true) {
[int]$date = get-date -Uformat %s
$exportlocation = New-Item -type file -path "c:\$date.csv"
Get-Counter -Counter "\Processor(_Total)\% Processor Time" | % {$_} | Out-File $exportlocation
start-sleep -s 5
}
For access cookie in whole app (use path=/):
function createCookie(name,value,days) {
if (days) {
var date = new Date();
date.setTime(date.getTime()+(days*24*60*60*1000));
var expires = "; expires="+date.toGMTString();
}
else var expires = "";
document.cookie = name+"="+value+expires+"; path=/";
}
Note:
If you set
path=/
,
Now the cookie is available for whole application/domain. If you not specify the path then current cookie is save just for the current page you can't access it on another page(s).
For more info read- http://www.quirksmode.org/js/cookies.html (Domain and path part)
If you use cookies in jquery by plugin jquery-cookie:
$.cookie('name', 'value', { expires: 7, path: '/' });
//or
$.cookie('name', 'value', { path: '/' });
$ find . -name \*.exe -o -name \*.dll -o -print
The first two -name options have no -print option, so they skipped. Everything else is printed.

There is another way to do XOR:
bool XOR(bool a, bool b)
{
return (a + b) % 2;
}
Which obviously can be demonstrated to work via:
#include <iostream>
bool XOR(bool a, bool b)
{
return (a + b) % 2;
}
int main()
{
using namespace std;
cout << "XOR(true, true):\t" << XOR(true, true) << endl
<< "XOR(true, false):\t" << XOR(true, false) << endl
<< "XOR(false, true):\t" << XOR(false, true) << endl
<< "XOR(false, false):\t" << XOR(false, false) << endl
<< "XOR(0, 0):\t\t" << XOR(0, 0) << endl
<< "XOR(1, 0):\t\t" << XOR(1, 0) << endl
<< "XOR(5, 0):\t\t" << XOR(5, 0) << endl
<< "XOR(20, 0):\t\t" << XOR(20, 0) << endl
<< "XOR(6, 6):\t\t" << XOR(5, 5) << endl
<< "XOR(5, 6):\t\t" << XOR(5, 6) << endl
<< "XOR(1, 1):\t\t" << XOR(1, 1) << endl;
return 0;

Try to telnet to the given address. In my case, there was a firewall in place blocking me.
I would use two classes. Keep your test class and add a second class called testhover which you only add to those you want to hover - alongside the test class. This isn't directly what you asked but without more context it feels like the best solution and is possibly the cleanest and simplest way of doing it.
Example:
.test { border: 0px; }_x000D_
.testhover:hover { border: 1px solid red; }
_x000D_
<div class="test"> blah </div>_x000D_
<div class="test"> blah </div>_x000D_
<div class="test testhover"> blah </div>
_x000D_

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);
var element = document.getElementById("main");
var values = element.childNodes[1].innerText;
alert('the value is:' + values);
To further refine it and retrieve the value Alec for example, use another .childNodes[1]
var element = document.getElementById("main");
var values = element.childNodes[1].childNodes[1].innerText;
alert('the value is:' + values);
Darin Dimitrov's solution worked for me with one exception. When I submitted the partial view with (intentional) validation errors, I ended up with duplicate forms being returned in the dialog:
To fix this I had to wrap the Html.BeginForm in a div:
<div id="myForm">
@using (Html.BeginForm("CreateDialog", "SupportClass1", FormMethod.Post, new { @class = "form-horizontal" }))
{
//form contents
}
</div>
When the form was submitted, I cleared the div in the success function and output the validated form:
$('form').submit(function () {
if ($(this).valid()) {
$.ajax({
url: this.action,
type: this.method,
data: $(this).serialize(),
success: function (result) {
$('#myForm').html('');
$('#result').html(result);
}
});
}
return false;
});
});
It's the same as the Objective-C API, but uses Swift's syntax.
Swift 4.2 & Swift 5:
NotificationCenter.default.addObserver(
self,
selector: #selector(self.batteryLevelChanged),
name: UIDevice.batteryLevelDidChangeNotification,
object: nil)
If your observer does not inherit from an Objective-C object, you must prefix your method with @objc
in order to use it as a selector.
@objc private func batteryLevelChanged(notification: NSNotification){
//do stuff using the userInfo property of the notification object
}
See NSNotificationCenter Class Reference, Interacting with Objective-C APIs
Adding .dockerignore works for me. One additional point Those who are trying this solution on Windows , windows will not let you create .dockerignore file (as it doesn't by default allows creating file starting with .)
To create such file starting with . on Windows, include an ending dot also, like : .dockerignore.
and hit enter ( provided you have enabled view extension options from folder options )
There are plenty of good answers, it just took me some time to understand what each element of the command was for and the logic behind it.
find . -path ./misc -prune -o -name '*.txt' -print
find will start finding files and directories in the current directory, hence the find .
.
The -o
option stands for a logical OR and separates the two parts of the command :
[ -path ./misc -prune ] OR [ -name '*.txt' -print ]
Any directory or file that is not the ./misc directory will not pass the first test -path ./misc
. But they will be tested against the second expression. If their name corresponds to the pattern *.txt
they get printed, because of the -print
option.
When find reaches the ./misc directory, this directory only satisfies the first expression. So the -prune
option will be applied to it. It tells the find command to not explore that directory. So any file or directory in ./misc will not even be explored by find, will not be tested against the second part of the expression and will not be printed.
You can try use in javascript:
window.onload = function() {
alert("let's go!");
}
Its a good practice separate javascript of html
You have to add the reference of the namespace : System.Windows.Forms to your project, because for some reason it is not already added, so you can add New Reference from Visual Studio menu.

I was curious about the relative speed of the two popular approaches - casting to string and using modular arithmetic - so I profiled them and was surprised to see how close they were in terms of performance.
(My use-case was slightly different, I wanted to get all digits in the number.)
The string approach gave:
10000002 function calls in 1.113 seconds
Ordered by: cumulative time
ncalls tottime percall cumtime percall filename:lineno(function)
10000000 1.113 0.000 1.113 0.000 sandbox.py:1(get_digits_str)
1 0.000 0.000 0.000 0.000 cProfile.py:133(__exit__)
1 0.000 0.000 0.000 0.000 {method 'disable' of '_lsprof.Profiler' objects}
While the modular arithmetic approach gave:
10000002 function calls in 1.102 seconds
Ordered by: cumulative time
ncalls tottime percall cumtime percall filename:lineno(function)
10000000 1.102 0.000 1.102 0.000 sandbox.py:6(get_digits_mod)
1 0.000 0.000 0.000 0.000 cProfile.py:133(__exit__)
1 0.000 0.000 0.000 0.000 {method 'disable' of '_lsprof.Profiler' objects}
There were 10^7 tests run with a max number size less than 10^28.
Code used for reference:
def get_digits_str(num):

def get_digits_mod(num, radix=10):
remaining = num
yield remaining % radix

The other answers are great and contain more detail if you want/need them.
In addition to those, I would like to add a TL;DR:
@RunWith(MockitoJUnitRunner.class)
@Rule public MockitoRule rule = MockitoJUnit.rule();
@Before public void initMocks() {
MockitoAnnotations.initMocks(this);
}
X x = mock(X.class)
(1) and (2) and (3) are mutually exclusive.
(4) can be used in combination with the others.
Try This:
(SELECT p.LastName, p.FirstName, o.OrderNo
FROM Persons p
LEFT JOIN Orders o
ON o.OrderNo = p.P_id
)
UNION
(SELECT p.LastName, p.FirstName, o.OrderNo
FROM Persons p
RIGHT JOIN Orders o
ON o.OrderNo = p.P_id
);
+----------+-----------+---------+
| LastName | FirstName | OrderNo |
+----------+-----------+---------+
| Singh | Shashi | 1 |
| Yadav | Sunil | NULL |
| Singh | Satya | NULL |
| Jain | Ankit | NULL |
| NULL | NULL | 11 |
| NULL | NULL | 12 |

It is possible to use full C# 6.0 features in Visual Studio 2013 if you have Resharper.
You have to enable Resharper Build and voilá!
In Resharper Options -> Build - enable Resharper Build and in "Use MSBuild.exe version" choose "Latest Installed"
This way Resharper is going to build your C# 6.0 Projects and will also not underline C# 6.0 code as invalid.
I am also using this although I have Visual Studio 2015 because:
I am putting this here, as I was looking for a solution for this problem for some time now and maybe it will help someone else.
import java.util.ArrayList;
import java.util.List;
class ArrLst{
public static void main(String args[]){
List l=new ArrayList();
l.add(10);
l.add(11);
l.add(12);
l.add(13);
l.add(14);
l.forEach((a)->System.out.println(a));
}
}
How about this?
var http = require('http'),
fs = require('fs'),
options;
options = {
host: 'www.google.com' ,
port: 80,
path: '/images/logos/ps_logo2.png'
}
var request = http.get(options, function(res){
//var imagedata = ''
//res.setEncoding('binary')
var chunks = [];
res.on('data', function(chunk){
//imagedata += chunk
chunks.push(chunk)
})
res.on('end', function(){
//fs.writeFile('logo.png', imagedata, 'binary', function(err){
var buffer = Buffer.concat(chunks)
fs.writeFile('logo.png', buffer, function(err){
if (err) throw err
console.log('File saved.')
})
})
This is called programming to interface. This will be helpful in case if you wish to move to some other implementation of List in the future. If you want some methods in ArrayList
then you would need to program to the implementation that is ArrayList a = new ArrayList()
.
Please ensure that you have following import. Ofcourse other standard imports

I found out that my web reference was out of date and the code was calling a removed web service.
You cannot prevent the process on the far end of a pipe from exiting, and if it exits before you've finished writing, you will get a SIGPIPE signal. If you SIG_IGN the signal, then your write will return with an error - and you need to note and react to that error. Just catching and ignoring the signal in a handler is not a good idea -- you must note that the pipe is now defunct and modify the program's behaviour so it does not write to the pipe again (because the signal will be generated again, and ignored again, and you'll try again, and the whole process could go on for a long time and waste a lot of CPU power).
Have you considered applying ON DELETE CASCADE
where relevant?
I think lucene syntax is supported so:
http://localhost:9200/foo/_search?pretty=true&q=*:*
size defaults to 10, so you may also need &size=BIGNUMBER
to get more than 10 items. (where BIGNUMBER equals a number you believe is bigger than your dataset)
BUT, elasticsearch documentation suggests for large result sets, using the scan search type.
EG:
curl -XGET 'localhost:9200/foo/_search?search_type=scan&scroll=10m&size=50' -d '
{
"query" : {
"match_all" : {}
}
}'
and then keep requesting as per the documentation link above suggests.
EDIT: scan
Deprecated in 2.1.0.
scan
does not provide any benefits over a regular scroll

I surveyed a few Excel modules for Python, and found openpyxl to be the best.
The free book Automate the Boring Stuff with Python has a chapter on openpyxl with more details or you can check the Read the Docs site. You won't need Office or Excel installed in order to use openpyxl.
Your program would look something like this:
import openpyxl
wb = openpyxl.load_workbook('example.xlsx')
sheet = wb.get_sheet_by_name('Sheet1')
stimulusTimes = [1, 2, 3]
reactionTimes = [2.3, 5.1, 7.0]
for i in range(len(stimulusTimes)):
sheet['A' + str(i + 6)].value = stimulusTimes[i]
sheet['B' + str(i + 6)].value = reactionTimes[i]
wb.save('example.xlsx')

Here's a solution using Bootstrap's affix plugin:
HTML:
<header class="container-fluid">
...
</header>
<nav class="navbar navbar-default navbar-static-top" role="navigation">
...
</nav>
Javascript:
$('nav').affix({
offset: {
top: $('header').height()
}
});
Set padding-top
to your body
equal to that of your nav
's height so that the content overlayed by the fixed navbar is visible.
$('nav').on('affix.bs.affix', function (){
$('body').css('margin-top', $('nav').height());
});
$('nav').on('affix-top.bs.affix', function (){
$('body').css('margin-top', 0);
});
To get the nav
to stick on top while scrolling add this bit of CSS.
CSS:
.affix
{
top: 0;
}
Since you may have more than one legends in a plot, a way to selectively remove just one of the titles without leaving an empty space is to set the name

To identify unlock screen I believe that you can use ID 4624. But then you also need to look at the Logon Type which in this case is 7: http://www.ultimatewindowssecurity.com/securitylog/encyclopedia/event.aspx?eventid=4624
Event ID for Logoff is 4634
Using the approach mentioned in the answer by Rick Byers:
top -p `pgrep java | paste -sd "," -`
but I had more than 20 processes running so following command can be helpful for someone who encounter a similar situation.
top -p `pgrep java | head -n 20 | paste -sd "," -`
pgrep
gets the list of processes with given name - java in this case. head
is used to get first 20 pids because top cannot handle more than 20 pids when using -p argument. Finally paste
joins the list of pids with ','.
You can control the process name you are looking for in the above command and the number of processes with that name you are interested to watch. You can ignore the head -n 20
part if the number of your processes with the given name is less than 20.
It hides the intention of the code.
It's two single tilde operators, so it does a bitwise complement (bitwise not) twice. The operations take out each other, so the only remaining effect is the conversion that is done before the first operator is applied, i.e. converting the value to an integer number.
Some use it as a faster alternative to Math.floor
, but the speed difference is not that dramatic, and in most cases it's just micro optimisation. Unless you have a piece of code that really needs to be optimised, you should use code that descibes what it does instead of code that uses a side effect of a non-operation.
With optimisation of the JavaScript engine in browsers, the performance for operators and functions change. With current browsers, using ~~
instead of Math.floor
is somewhat faster in some browsers, and not faster at all in some browsers. If you really need that extra bit of performance, you would need to write different optimised code for each browser.

If your images are small, consider storing them as base64 in a plain text field.
The reason is that while base64 has an overhead of 33%, with compression that mostly goes away. (See What is the space overhead of Base64 encoding?) Your database will be bigger, but the packets your webserver sends to the client won't be. In html, you can inline base64 in an <img src=""> tag, which can possibly simplify your app because you won't have to serve up the images as binary in a separate browser fetch. Handling images as text also simplifies things when you have to send/receive json, which doesn't handle binary very well.
Yes, I understand you could store the binary in the database and convert it to/from text on the way in and out of the database, but sometimes ORMs make that a hassle. It can be simpler just to treat it as straight text just like all your other fields.
This is definitely the right way to handle thumbnails.
(OP's images are not small, so this is not really an answer to his question.)
You can use JPQL:
TypedQuery <Object[]> query = em.createQuery(
"SELECT p.projectId, p.projectName FROM projects AS p", Object[].class);
List<Object[]> results = query.getResultList();
or you can use native sql query.
Query query = em.createNativeQuery("sql statement");
List<Object[]> results = query.getResultList();
The only time to use java.sql.Date
is in a PreparedStatement.setDate
. Otherwise, use java.util.Date
. It's telling that ResultSet.getDate
returns a java.sql.Date
but it can be assigned directly to a java.util.Date
.
For Linux let me introduce a shell script that will show the mac address and allows to change it (MAC sniffing).
ifconfig eth0 | grep HWaddr |cut -dH -f2|cut -d\ -f2
00:26:6c:df:c3:95
Cut arguements may dffer (I am not an expert) try:
ifconfig etho | grep HWaddr
eth0 Link encap:Ethernet HWaddr 00:26:6c:df:c3:95
To change MAC we may do:
ifconfig eth0 down
ifconfig eth0 hw ether 00:80:48:BA:d1:30
ifconfig eth0 up
will change mac address to 00:80:48:BA:d1:30 (temporarily, will restore to actual one upon reboot).
If you have installed mongodb through homebrew
then you can simply start mongodb through

For more options
brew info mongodb
The bottom statement is equivalent to:
.half {
flex-grow: 0;
flex-shrink: 0;
flex-basis: 50%;
}
Which, in this case, would be equivalent as the box is not allowed to flex and therefore retains the initial width set by flex-basis.
Flex-basis defines the default size of an element before the remaining space is distributed so if the element were allowed to flex (grow/shrink) it may not be 50% of the width of the page.
I've found that I regularly return to https://css-tricks.com/snippets/css/a-guide-to-flexbox/ for help regarding flexbox :)

I was also wondering how to store it cleanly in a variable. As using
char c = '•';
is not very good practice (I guess). I found out the following way of storing it in a variable
char c = (char)0x2022;// or 0x25cf depending on the one you choose
or even cleaner
char c = '\u2022';// or "\u25cf"
https://msdn.microsoft.com/en-us/library/aa664669%28v=vs.71%29.aspx
same for strings
string s = "\u2022";
My take on it...obviously, you've got to do something with the data you read in. If it involves writing it to the sheet, that'll be deadly slow with a normal For Loop. I came up with the following based upon a rehash of some of the items there, plus some help from the Chip Pearson website.
Reading in the text file (assuming you don't know the length of the range it will create, so only the startingCell is given):
Public Sub ReadInPlainText(startCell As Range, Optional textfilename As Variant)
If IsMissing(textfilename) Then textfilename = Application.GetOpenFilename("All Files (*.*), *.*", , "Select Text File to Read")
If textfilename = "" Then Exit Sub
Dim filelength As Long
Dim filenumber As Integer
filenumber = FreeFile
filelength = filelen(textfilename)
Dim text As String
Dim textlines As Variant
Open textfilename For Binary Access Read As filenumber
text = Space(filelength)
Get #filenumber, , text
'split the file with vbcrlf
textlines = Split(text, vbCrLf)
'output to range
Dim outputRange As Range
Set outputRange = startCell
Set outputRange = outputRange.Resize(UBound(textlines), 1)
outputRange.Value = Application.Transpose(textlines)
Close filenumber
End Sub
Conversely, if you need to write out a range to a text file, this does it quickly in one print statement (note: the file 'Open' type here is in text mode, not binary..unlike the read routine above).
Public Sub WriteRangeAsPlainText(ExportRange As Range, Optional textfilename As Variant)
If IsMissing(textfilename) Then textfilename = Application.GetSaveAsFilename(FileFilter:="Text Files (*.txt), *.txt")
If textfilename = "" Then Exit Sub
Dim filenumber As Integer
filenumber = FreeFile
Open textfilename For Output As filenumber
Dim textlines() As Variant, outputvar As Variant
textlines = Application.Transpose(ExportRange.Value)
outputvar = Join(textlines, vbCrLf)
Print #filenumber, outputvar
Close filenumber
End Sub

ABI
- Application Binary Interface
is about a machine code communication in runtime between two binary parts like - application, library, OS... ABI
describes how objects are saved in memory, how functions are called(calling convention
), mangling...
A good example of API and ABI is iOS ecosystem with Swift language.
Application layer
- When you create an application using different languages. For example you can create application using Swift
and Objective-C
[Mixing Swift and Objective-C]
Application - OS layer
- runtime - Swift runtime
and standard libraries
are parts of OS and they should not be included into each bundle(e.g. app, framework). It is the same as like Objective-C uses
Library layer
- Module Stability
case - compile time - you will be able to import a framework which was built with another version of Swift's compiler. It means that it is safety to create a closed-source(pre-build) binary which will be consumed by a different version of compiler( .swiftinterface
is used with .swiftmodule
) and you will not get
Module compiled with _ cannot be imported by the _ compiler
Library layer
- Library Evolution
case
<T>
is a generic and can usually be read as "of type T". It depends on the type to the left of the <> what it actually means.
I don't know what a Pool
or PoolFactory
is, but you also mention ArrayList<T>
, which is a standard Java class, so I'll talk to that.
Usually, you won't see "T" in there, you'll see another type. So if you see ArrayList<Integer>
for example, that means "An ArrayList
of Integer
s." Many classes use generics to constrain the type of the elements in a container, for example. Another example is HashMap<String, Integer>
, which means "a map with String
keys and Integer
values."
Your Pool example is a bit different, because there you are defining a class. So in that case, you are creating a class that somebody else could instantiate with a particular type in place of T. For example, I could create an object of type Pool<String>
using your class definition. That would mean two things:
Pool<String>
would have an interface PoolFactory<String>
with a createObject
method that returns String
s.Pool<String>
would contain an ArrayList
of Strings.This is great news, because at another time, I could come along and create a Pool<Integer>
which would use the same code, but have Integer
wherever you see T
in the source.
If you just want to change file permissions, you want to be careful about using -R
on chmod
since it will change anything, files or folders. If you are doing a relative change (like adding write permission for everyone), you can do this:
sudo chmod -R a+w /var/www
But if you want to use the literal permissions of read/write, you may want to select files versus folders:
sudo find /var/www -type f -exec chmod 666 {} \;
(Which, by the way, for security reasons, I wouldn't recommend either of these.)
Or for folders:
sudo find /var/www -type d -exec chmod 755 {} \;
One thing that might be useful to you (besides the already valid/good answers provided so far) is the StringEnum idea provided here
With this you can define your enumerations as classes (the examples are in vb.net):
< StringEnumRegisteredOnly(), DebuggerStepThrough(), ImmutableObject(True)> Public NotInheritable Class eAuthenticationMethod Inherits StringEnumBase(Of eAuthenticationMethod)
Private Sub New(ByVal StrValue As String) MyBase.New(StrValue) End Sub < Description("Use User Password Authentication")> Public Shared ReadOnly UsernamePassword As New eAuthenticationMethod("UP") < Description("Use Windows Authentication")> Public Shared ReadOnly WindowsAuthentication As New eAuthenticationMethod("W")
End Class
And now you could use the this class as you would use an enum: eAuthenticationMethod.WindowsAuthentication and this would be essentially like assigning the 'W' the logical value of WindowsAuthentication (inside the enum) and if you were to view this value from a properties window (or something else that uses the System.ComponentModel.Description property) you would get "Use Windows Authentication".
I've been using this for a long time now and it makes the code more clear in intent.
Performing a single click on an HTML element: Simply do element.click()
. Most major browsers support this.
To repeat the click more than once: Add an ID to the element to uniquely select it:
<a href="#" target="_blank" id="my-link" onclick="javascript:Test('Test');">Google Chrome</a>
and call the .click()
method in your JavaScript code via a for loop:
var link = document.getElementById('my-link');
for(var i = 0; i < 50; i++)
link.click();
I had a similar problem but all answers here didn't help me.
For me the problem was a failing test. If you are doing test driven development than a failing / not implemented test shouldn't break the build. I still want my project to build.
To solve this I added a configuration to surefire so that it ignores a failing test.
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>2.19.1</version>
<configuration>
<testFailureIgnore>true</testFailureIgnore>
</configuration>

In Laravel 3, call path('storage')

In Laravel 4, use the storage_path()
helper function.
OK. If you don't want to use the correct way ng-options
, you can add ng-selected
attribute with a condition check logic for the option
directive to to make the pre-select work.
<select ng-model="filterCondition.operator">
<option ng-selected="{{operator.value == filterCondition.operator}}"
ng-repeat="operator in operators"
value="{{operator.value}}">
{{operator.displayName}}
</option>
</select>
You could also check to make sure the DLLs you're looking for aren't included in the GAC. I believe Visual Studio is being smart about not copying those files if it already exists in the GAC on the build machine.
I recently ran in this situation where I'd been testing an SSIS package that needed assemblies to exist in the GAC. I'd since forgotten that and was wondering why those DLLs weren't coming out during a build.
To check what's in the GAC (from a Visual Studio Developer Command Prompt):
gacutil -l
Or output to a file to make it easier to read:
gacutil -l > output.txt
notepad.exe output.txt
To remove an assembly:
gacutil -u MyProjectAssemblyName
I should also note, that once I removed the files from the GAC they were correctly output in the \bin directory after a build (Even for assemblies that were not directly referenced in the root project). This was on Visual Studio 2013 Update 5.
subprocess.call
Automatically waits , you can also use:
p1.wait()
You need to do this in transaction to ensure two simultaneous clients won't insert same fieldValue twice:
SET TRANSACTION ISOLATION LEVEL SERIALIZABLE
BEGIN TRANSACTION
DECLARE @id AS INT
SELECT @id = tableId FROM table WHERE fieldValue=@newValue
IF @id IS NULL
BEGIN
INSERT INTO table (fieldValue) VALUES (@newValue)
SELECT @id = SCOPE_IDENTITY()
END
SELECT @id
COMMIT TRANSACTION
you can also use Double-checked locking to reduce locking overhead
DECLARE @id AS INT
SELECT @id = tableID FROM table (NOLOCK) WHERE fieldValue=@newValue
IF @id IS NULL
BEGIN
SET TRANSACTION ISOLATION LEVEL SERIALIZABLE
BEGIN TRANSACTION
SELECT @id = tableID FROM table WHERE fieldValue=@newValue
IF @id IS NULL
BEGIN
INSERT INTO table (fieldValue) VALUES (@newValue)
SELECT @id = SCOPE_IDENTITY()
END
COMMIT TRANSACTION
END
SELECT @id
As for why ISOLATION LEVEL SERIALIZABLE is necessary, when you are inside a serializable transaction, the first SELECT that hits the table creates a range lock covering the place where the record should be, so nobody else can insert the same record until this transaction ends.
Without ISOLATION LEVEL SERIALIZABLE, the default isolation level (READ COMMITTED) would not lock the table at read time, so between SELECT and UPDATE, somebody would still be able to insert. Transactions with READ COMMITTED isolation level do not cause SELECT to lock. Transactions with REPEATABLE READS lock the record (if found) but not the gap.
Or simply:
Date.now
From MDN documentation:
The Date.now() method returns the number of milliseconds elapsed since January 1, 1970
Available since ECMAScript 5.1
It's the same as was mentioned above (new Date().getTime()
), but more shortcutted version.

If one wants to get the line count cheaply in Python in Linux, I recommend this method:
import os
print os.popen("wc -l file_path").readline().split()[0]
file_path can be both abstract file path or relative path. Hope this may help.
You may also use all() method to get array of selected attributes.

As of Java 7 (and Android API level 19):
System.lineSeparator()
Documentation: Java Platform SE 7
For older versions of Java, use:
System.getProperty("line.separator");
See https://java.sun.com/docs/books/tutorial/essential/environment/sysprop.html for other properties.
You could use a separate file, like npm_globals.txt
, instead of package.json
. This file would contain each module on a new line like this,
[email protected]
[email protected]
[email protected]
[email protected]
[email protected]
Then in the command line run,
< npm_globals.txt xargs npm install -g
Check that they installed properly with,
npm list -g --depth=0
As for whether you should do this or not, I think it all depends on use case. For most projects, this isn't necessary; and having your project's package.json
encapsulate these tools and dependencies together is much preferred.
But nowadays I find that I'm always installing create-react-app
and other CLI's globally when I jump on a new machine. It's nice to have an easy way to install a global tool and its dependencies when versioning doesn't matter much.
And nowadays, I'm using npx
, an npm package runner, instead of installing packages globally.
Try This. You need pass the authentication to let the server know its a valid user. You need to import these two packages and has to include a jersy jar. If you dont want to include jersy jar then import this package
import sun.misc.BASE64Encoder;
import com.sun.jersey.core.util.Base64;
import sun.net.www.protocol.http.HttpURLConnection;
and then,
String encodedAuthorizedUser = getAuthantication("username", "password");
URL url = new URL("Your Valid Jira URL");
HttpURLConnection httpCon = (HttpURLConnection) url.openConnection();
httpCon.setRequestProperty ("Authorization", "Basic " + encodedAuthorizedUser );
public String getAuthantication(String username, String password) {
String auth = new String(Base64.encode(username + ":" + password));
return auth;
}
In xamarin if you face this issue when you add any new sdk. The simple solution is Open your styles file and add this line.
<style name="AppTheme" parent="android:Theme.Holo.Light.DarkActionBar"></style>
It's better solution rather than adding appcompat.
Cannot delete or update a parent row: a foreign key constraint fails (table1
.user_role
, CONSTRAINT FK143BF46A8dsfsfds@#5A6BD60
FOREIGN KEY (user_id
) REFERENCES user
(id
))
What i did in two simple steps . first i delete the child row in child table like
mysql> delete from table2 where role_id = 2 && user_id =20;
Query OK, 1 row affected (0.10 sec)
and second step as deleting the parent
delete from table1 where id = 20;
Query OK, 1 row affected (0.12 sec)
By this i solve the Problem which means Delete Child then Delete parent
i Hope You got it. :)
There are several to pick from in the gallery but the one I'm using, which offers considerable level of configurability still remaining unobtrusive to the rest of the settings is Beautify by Michele Melluso. It works on both CSS and SCSS and lets you indent 3 spaces keeping the rest of the code at 2 spaces, which is nice.
You can snatch it from GitHub and adapt it yourself, should you feel like it too.
CTRL+SHIFT+D
And there are many shortcuts you can see them by going to
Settings » Shortcuts, as displayed here:
Alternatively, use CTRL + ? to go to the settings, from there one can reach the "Shortcuts" sub-item on the left or use the Official reference.
Look at the following:
echo "ls -l" | at 07:00
This code line executes "ls -l" at a specific time. This is an example of executing something (a command in my example) at a specific time. "at" is the command you were really looking for. You can read the specifications here:

Hope it helps!
This seems to have changed in the latest version of React Native when using refs to calculate.
Declare refs this way.
<View
ref={(image) => {
this._image = image
}}>
And find the value this way.
_measure = () => {
this._image._component.measure((width, height, px, py, fx, fy) => {
const location = {
fx: fx,
fy: fy,
px: px,
py: py,
width: width,
height: height
}
console.log(location)
})
}
If you must use a 2d array:
int numOfPairs = 10; String[][] array = new String[numOfPairs][2]; for(int i = 0; i < array.length; i++){ for(int j = 0; j < array[i].length; j++){ array[i] = new String[2]; array[i][0] = "original word"; array[i][1] = "rearranged word"; } }
Does this give you a hint?
As mentioned before, you need more than a css selector because it doesn't access the stored value of the node, so javascript is definitely needed. Heres another possible solution:
<style>
input:not([value=""]){
border:2px solid red;
}
</style>
<input type="text" onkeyup="this.setAttribute('value', this.value);"/>
Try this:
function createcodes() {
$('.authors-list tr').each(function () {
//processing this row
//how to process each cell(table td) where there is checkbox
$(this).find('td input:checked').each(function () {
// it is checked, your code here...
});
});
}
First of all you need to include in your project
using System.Diagnostics;
After that you could write a general method that you could use for different .exe files that you want to use. It would be like below:
public void ExecuteAsAdmin(string fileName)
{
Process proc = new Process();
proc.StartInfo.FileName = fileName;
proc.StartInfo.UseShellExecute = true;
proc.StartInfo.Verb = "runas";
proc.Start();
}
If you want to for example execute notepad.exe then all you do is you call this method:
ExecuteAsAdmin("notepad.exe");
If you have the pecl/http extension installed, you can also use this:
$request = new http\Env\Request();
$request->getBody();
OK, we may get confused when we hear about null
and undefined
, but let's start it simple, they both are falsy and similar in many ways, but weird part of JavaScript, make them a couple of significant differences, for example, typeof null
is 'object'
while typeof undefined
is 'undefined'
.
typeof null; //"object"
typeof undefined; //"undefined";
But if you check them with ==
as below, you see they are both falsy:
null==undefined; //true
Also you can assign null
to an object property or to a primitive, while undefined
can simply be achieved by not assigning to anything.
I create a quick image to show the differences for you at a glance.
Alternatively you can have your class implement the InitializingBean
interface to provide a callback function (afterPropertiesSet()
) which the ApplicationContext will invoke when the bean is constructed.
I know the question is about GCC, but I thought it might be useful to have some information about compilers other compilers as well.
GCC's
noinline
function attribute is pretty popular with other compilers as well. It
is supported by at least:
__has_attribute(noinline)
)__TI_GNU_ATTRIBUTE_SUPPORT__
)Additionally, MSVC supports
__declspec(noinline)
back to Visual Studio 7.1. Intel probably supports it too (they try to
be compatible with both GCC and MSVC), but I haven't bothered to
verify that. The syntax is basically the same:
__declspec(noinline)
static void foo(void) { }
PGI 10.2+ (and probably older) supports a noinline
pragma which
applies to the next function:
#pragma noinline
static void foo(void) { }
TI 6.0+ supports a
FUNC_CANNOT_INLINE
pragma which (annoyingly) works differently in C and C++. In C++, it's similar to PGI's:
#pragma FUNC_CANNOT_INLINE;
static void foo(void) { }
In C, however, the function name is required:
#pragma FUNC_CANNOT_INLINE(foo);
static void foo(void) { }
Cray 6.4+ (and possibly earlier) takes a similar approach, requiring the function name:
#pragma _CRI inline_never foo
static void foo(void) { }
Oracle Developer Studio also supports a pragma which takes the function name, going back to at least Forte Developer 6, but note that it needs to come after the declaration, even in recent versions:
static void foo(void);
#pragma no_inline(foo)
Depending on how dedicated you are, you could create a macro that would work everywhere, but you would need to have the function name as well as the declaration as arguments.
If, OTOH, you're okay with something that just works for most people, you can get away with something which is a little more aesthetically pleasing and doesn't require repeating yourself. That's the approach I've taken for Hedley, where the current version of HEDLEY_NEVER_INLINE looks like:
#if \
HEDLEY_GNUC_HAS_ATTRIBUTE(noinline,4,0,0) || \
HEDLEY_INTEL_VERSION_CHECK(16,0,0) || \
HEDLEY_SUNPRO_VERSION_CHECK(5,11,0) || \
HEDLEY_ARM_VERSION_CHECK(4,1,0) || \
HEDLEY_IBM_VERSION_CHECK(10,1,0) || \
HEDLEY_TI_VERSION_CHECK(8,0,0) || \
(HEDLEY_TI_VERSION_CHECK(7,3,0) && defined(__TI_GNU_ATTRIBUTE_SUPPORT__))
# define HEDLEY_NEVER_INLINE __attribute__((__noinline__))
#elif HEDLEY_MSVC_VERSION_CHECK(13,10,0)
# define HEDLEY_NEVER_INLINE __declspec(noinline)
#elif HEDLEY_PGI_VERSION_CHECK(10,2,0)
# define HEDLEY_NEVER_INLINE _Pragma("noinline")
#elif HEDLEY_TI_VERSION_CHECK(6,0,0)
# define HEDLEY_NEVER_INLINE _Pragma("FUNC_CANNOT_INLINE;")
#else
# define HEDLEY_NEVER_INLINE HEDLEY_INLINE
#endif
If you don't want to use Hedley (it's a single public domain / CC0 header) you can convert the version checking macros without too much effort, but more than I'm willing to put in ?.
Here is my take on this issue. The following retry
function supports the following features:
import time
def retry(func, ex_type=Exception, limit=0, wait_ms=100, wait_increase_ratio=2, logger=None):
attempt = 1
while True:
try:
return func()
except Exception as ex:
if not isinstance(ex, ex_type):
raise ex
if 0 < limit <= attempt:
if logger:
logger.warning("no more attempts")
raise ex
if logger:
logger.error("failed execution attempt #%d", attempt, exc_info=ex)
attempt += 1
if logger:
logger.info("waiting %d ms before attempt #%d", wait_ms, attempt)
time.sleep(wait_ms / 1000)
wait_ms *= wait_increase_ratio
Usage:
def fail_randomly():
y = random.randint(0, 10)
if y < 10:
y = 0
return x / y
logger = logging.getLogger()
logger.setLevel(logging.INFO)
logger.addHandler(logging.StreamHandler(stream=sys.stdout))
logger.info("starting")
result = retry.retry(fail_randomly, ex_type=ZeroDivisionError, limit=20, logger=logger)
logger.info("result is: %s", result)
See my post for more info.
You must specify that the friend is a template function:
MyClass<T>& operator+=<>(const MyClass<T>& classObj);
See this C++ FAQ Lite answer for details.
If you have a unique key, you may use COUNT(*) OVER ( ORDER BY unique_key ) as ROWNUM
SELECT t.*, count(*) OVER (ORDER BY k ) ROWNUM
FROM yourtable t;

| a | TEST1 | 1 |
| b | TEST2 | 2 |
| c | TEST2 | 3 |
| d | TEST4 | 4 |
In Jupyter Notebook,
SHIFT+ TAB(to move left) and TAB(to move right) movement is perfectly working.
It's even easier to do without a library
window.onload = function() {
// code
};
(<HTMLInputElement>document.getElementById('loginInput')).value = '123';
Angular cannot take HTML elements directly thereby you need to specify the element type by binding the above generic to it.
UPDATE::
This can also be done using ViewChild with #localvariable as shown here, as mentioned in here
<textarea #someVar id="tasknote"
name="tasknote"
[(ngModel)]="taskNote"
placeholder="{{ notePlaceholder }}"
style="background-color: pink"
(blur)="updateNote() ; noteEditMode = false " (click)="noteEditMode = false"> {{ todo.note }}
</textarea>
import {ElementRef,Renderer2} from '@angular/core';
@ViewChild('someVar') el:ElementRef;
constructor(private rd: Renderer2) {}
ngAfterViewInit() {
console.log(this.rd);
this.el.nativeElement.focus(); //<<<=====same as oldest way
}
I don't yet have a large enough reputation score to add a comment where it would be most helpful, but this is in relation to those asking about a .Net 4.5 solution.
You can use the mouse X and Y co-ordinates and the ListView method GetItemAt to find the item which has been clicked on.
private void ListView_MouseDoubleClick(object sender, MouseButtonEventArgs e)
{
ListViewItem item = myListView.GetItemAt(e.X, e.Y)
// Do something here
}
A pure PowerShell alternative that works with PowerShell 3 and .NET 4.5 (if you can use it):
function ZipFiles( $zipfilename, $sourcedir )
{
Add-Type -Assembly System.IO.Compression.FileSystem
$compressionLevel = [System.IO.Compression.CompressionLevel]::Optimal
[System.IO.Compression.ZipFile]::CreateFromDirectory($sourcedir,
$zipfilename, $compressionLevel, $false)
}
Just pass in the full path to the zip archive you would like to create and the full path to the directory containing the files you would like to zip.
The accepted answer is correct, but there is a more clever/efficient way to do this if you need to convert a whole bunch of ASCII characters to their ASCII codes at once. Instead of doing:
for ch in mystr:
code = ord(ch)
or the slightly faster:
for code in map(ord, mystr):
you convert to Python native types that iterate the codes directly. On Python 3, it's trivial:
for code in mystr.encode('ascii'):
and on Python 2.6/2.7, it's only slightly more involved because it doesn't have a Py3 style bytes
object (bytes
is an alias for str
, which iterates by character), but they do have bytearray
:
# If mystr is definitely str, not unicode
for code in bytearray(mystr):
# If mystr could be either str or unicode
for code in bytearray(mystr, 'ascii'):
Encoding as a type that natively iterates by ordinal means the conversion goes much faster; in local tests on both Py2.7 and Py3.5, iterating a str
to get its ASCII codes using map(ord, mystr)
starts off taking about twice as long for a len
10 str
than using bytearray(mystr)
on Py2 or mystr.encode('ascii')
on Py3, and as the str
gets longer, the multiplier paid for map(ord, mystr)
rises to ~6.5x-7x.
The only downside is that the conversion is all at once, so your first result might take a little longer, and a truly enormous str
would have a proportionately large temporary bytes
/bytearray
, but unless this forces you into page thrashing, this isn't likely to matter.
When you call document.write
after a page has loaded it will eliminate all content and replace it with the parameter you provide. Instead use DOM methods to add content, for example:
var OpenWindow = window.open('mypage.html','_blank','width=335,height=330,resizable=1');
var text = document.createTextNode('hi');
OpenWindow.document.body.appendChild(text);
If you want to use jQuery you get some better APIs to deal with. For example:
var OpenWindow = window.open('mypage.html','_blank','width=335,height=330,resizable=1');
$(OpenWindow.document.body).append('<p>hi</p>');
If you need the code to run after the new window's DOM is ready try:
var OpenWindow = window.open('mypage.html','_blank','width=335,height=330,resizable=1');
$(OpenWindow.document.body).ready(function() {
$(OpenWindow.document.body).append('<p>hi</p>');
});
$_SERVER['HTTP_REFERER']
is the answer
I know this is a bit old, but instead of looping through the array with a for loop, it would be much easier to use the method <array>.indexOf(<element>[, fromIndex])
It loops through an array, finding and returning the first index of a value. If the value is not contained in the array, it returns -1.
<array>
is the array to look through, <element>
is the value you are looking for, and [fromIndex]
is the index to start from (defaults to 0).
I hope this helps reduce the size of your code!
Ok, finally found the solution.
Probably due to lack of experience with ReactJS and web development...
var Task = React.createClass({
render: function() {
var percentage = this.props.children + '%';
....
<div className="ui-progressbar-value ui-widget-header ui-corner-left" style={{width : percentage}}/>
...
I created the percentage variable outside in the render function.
This is an old question, and the answers already given all work, but there's also a new option which can be considered.

You probably had using namespace std;
before in your code you did in class. That explicitly tells the precompiler to look for the symbols in std
, which means you don't need to std::
. Though it is good practice to std::cout
instead of cout
so you explicitly invoke std::cout
every time. That way if you are using another library that redefines cout
, you still have the std::cout
behavior instead of some other custom behavior.
Perhaps there is a shorter way but this works for me.

Generalizing Afanasii Kurakin's answer, we have:
function replaceAt(str, index, ch) {
return str.replace(/./g, (c, i) => i == index ? ch : c);
}
let str = 'Hello World';
str = replaceAt(str, 1, 'u');
console.log(str); // Hullo World
_x000D_
Let's expand and explain both the regular expression and the replacer function:
function replaceAt(str, index, newChar) {
function replacer(origChar, strIndex) {
if (strIndex === index)
return newChar;
else
return origChar;
}
return str.replace(/./g, replacer);
}
let str = 'Hello World';
str = replaceAt(str, 1, 'u');
console.log(str); // Hullo World
_x000D_
The regular expression .
matches exactly one character. The g
makes it match every character in a for loop. The replacer
function is called given both the original character and the index of where that character is in the string. We make a simple if
statement to determine if we're going to return either origChar
or newChar
.

You can use assertj-fluent assertions. It has lot of capabilities to write assertions in more human readable - user friendly manner.
In your case, it would be
String x = "foo bar";
assertThat(x).contains("foo");
It is not only for the strings, it can be used to assert lists, collections etc.. in a friendlier way

Then run following commands and enter the login password for vnc connection:
su - awsgui
vncserver
vncserver -kill :1
vim /home/awsgui/.vnc/xstartup
Then hit the Insert key, scroll around the text file with the keyboard arrows, and delete the pound (#) sign from the beginning of the two lines under the line that says "Uncomment the following two lines for normal desktop." And on the second line add "sh" so the line reads
exec sh /etc/X11/xinit/xinitrc.
When you're done, hit Ctrl + C on the keyboard, type :wq and hit Enter.
Then start vnc server again.

You can download xtightvncviewer
to view desktop(for Ubutnu) from here https://help.ubuntu.com/community/VNC/Clients
In the vnc client, give public DNS plus ":1" (e.g. www.example.com:1). Enter the vnc login password. Make sure to use a normal connection. Don't use the key files.
Additional guide available here: http://www.serverwatch.com/server-tutorials/setting-up-vnc-on-ubuntu-in-the-amazon-ec2-Page-3.html
Mac VNC client can be downloaded from here: https://www.realvnc.com/en/connect/download/viewer/
Port opening on console
sudo iptables -A INPUT -p tcp --dport 5901 -j ACCEPT
If the grey window issue comes. Mostly because of ".vnc/xstartup" file on different user. So run the vnc server also on same user instead of "awsgui" user.

I would really recommend to:
push only to the main repo
make sure that main repo is a bare repo, in order to never have any problem with the main repo working tree being not in sync with its .git
base. See "How to push a local git repository to another computer?"
If you do have to make modification in the main (bare) repo, clone it (on the main server), do your modification and push back to it
In other words, keep a bare repo accessible both from the main server and the local computer, in order to have a single upstream repo from/to which to pull/pull.
If you're starting with a DOM element, check for a __vue__
property on that element. Any Vue View Models (components, VMs created by v-repeat
usage) will have this property.
You can use the "Inspect Element" feature in your browsers developer console (at least in Firefox and Chrome) to view the DOM properties.
Hope that helps!

If you are trying to do something very similar: a is not None
, the same issue comes up. That is, Numpy complains that one must use a.any
or a.all
.
A workaround is to do:
if not (a is None):
pass
Not too pretty, but it does the job.
Like gabuzo said, sometimes I use AtomicIntegers when I want to pass an int by reference. It's a built-in class that has architecture-specific code, so it's easier and likely more optimized than any MutableInteger I could quickly code up. That said, it feels like an abuse of the class.
How about
dict2.forEach { (k,v) in dict1[k] = v }
That adds all of dict2's keys and values into dict1.
1- Open file:
C:\wamp\bin\mysql\mysql5.5.24\my.ini
2- Look for [mysqld] entry and append:

The whole view should look like:
[mysqld]
port=3306
character-set-server = utf8
skip-character-set-client-handshake
3- Restart MySQL service!
Simply remove the line that rotates it one degree at a time and calls the script forever.
// Animate rotation with a recursive call
setTimeout(function() { rotate(++degree); },65);
Then pass the desired value into the function... in this example 45
for 45 degrees.
$(function() {
var $elie = $("#bkgimg");
rotate(45);
function rotate(degree) {
// For webkit browsers: e.g. Chrome
$elie.css({ WebkitTransform: 'rotate(' + degree + 'deg)'});
// For Mozilla browser: e.g. Firefox
$elie.css({ '-moz-transform': 'rotate(' + degree + 'deg)'});
}
});
Change .css()
to .animate()
in order to animate the rotation with jQuery. We also need to add a duration for the animation, 5000 for 5 seconds. And updating your original function to remove some redundancy and support more browsers...
$(function() {
var $elie = $("#bkgimg");
rotate(45);
function rotate(degree) {
$elie.animate({
'-webkit-transform': 'rotate(' + degree + 'deg)',
'-moz-transform': 'rotate(' + degree + 'deg)',
'-ms-transform': 'rotate(' + degree + 'deg)',
'-o-transform': 'rotate(' + degree + 'deg)',
'transform': 'rotate(' + degree + 'deg)',
'zoom': 1
}, 5000);
}
});
EDIT: The standard jQuery CSS animation code above is not working because apparently, jQuery .animate()
does not yet support the CSS3 transforms
.
This jQuery plugin is supposed to animate the rotation:
Just call it and supply self
class A:
def m(self, x, y):
print(x+y)
class B:
def call_a(self):
A.m(self, 1, 2)
b = B()
b.call_a()
output: 3
Coding in Perl, I used the rand() function that generates the number at random and wanted only 1, 2, or 3 to be randomly selected. Due to Perl printing out the number one when doing "1 + " ... so I also did a if else statement that if the number generated zero, run the function again, and it works like a charm.
printing out the results will always give a random number of either 1, 2, or 3.
That is just another idea and sure people will say that is newbie stuff but at the same time, I am a newbie but it works. My issue was when printing out my stuff, it kept spitting out that 1 being used to start at 1 and not zero for indexing.
This is an elegant and simpler solution to find primes using a stored list. Starts with a 4 variables, you only have to test odd primes for divisors, and you only have to test up to a half of what number you are testing as a prime (no point in testing whether 9, 11, 13 divide into 17). It tests previously stored primes as divisors.`
# Program to calculate Primes
primes = [1,3,5,7]
for n in range(9,100000,2):
for x in range(1,(len(primes)/2)):
if n % primes[x] == 0:
break
else:
primes.append(n)
print primes

This is roughly how I'd do it: the line is created by setting a border-bottom
on the containing h2
then giving the h2
a smaller line-height
. The text is then put in a nested span
with a non-transparent background.
h2 {_x000D_
width: 100%; _x000D_
text-align: center; _x000D_
border-bottom: 1px solid #000; _x000D_
line-height: 0.1em;_x000D_
margin: 10px 0 20px; _x000D_
} _x000D_
_x000D_
h2 span { _x000D_
background:#fff; _x000D_
padding:0 10px; _x000D_
}
_x000D_
<h2><span>THIS IS A TEST</span></h2>_x000D_
<p>this is some content other</p>

I don't think you can use "exists" on an integer in Perl, only on collections. Can you give an example of what you mean in Perl which matches your example in Java.
Given an expression that specifies a hash element or array element, returns true if the specified element in the hash or array has ever been initialized, even if the corresponding value is undefined.
This indicates it only applies to hash or array elements!

It means to interpret the string literally (that is, you cannot escape any characters within the string if you use the @ prefix). It enhances readability in cases where it can be used.
For example, if you were working with a UNC path, this:
@"\\servername\share\folder"
is nicer than this:
"\\\\servername\\share\\folder"
Is not recommended but.... you can use componentWillMount from your app class to add your global variables trough it... a bit like so:
componentWillMount: function () {
window.MyVars = {
ajax: require('../helpers/ajax.jsx'),
utils: require('../helpers/utils.jsx')
};
}
still consider this a hack... but it will get your job done
btw componentWillMount executes once before rendering, see more here: https://reactjs.org/docs/react-component.html#mounting-componentwillmount

All functions in Java are virtual by default.
You have to go out of your way to write non-virtual functions by adding the "final" keyword.
This is the opposite of the C++/C# default. Class functions are non-virtual by default; you make them so by adding the "virtual" modifier.
The scrolling effect is cause by specifying the generic 'background' property in your css instead of the more specific background-image. By setting the background property, the animation will transition between all properties.. Background-Color, Background-Image, Background-Position.. Etc Thus causing the scrolling effect..
E.g.
a {
-webkit-transition-property: background-image 300ms ease-in 200ms;
-moz-transition-property: background-image 300ms ease-in 200ms;
-o-transition-property: background-image 300ms ease-in 200ms;
transition: background-image 300ms ease-in 200ms;
}
git push
can push all branches or a single one dependent on this configuration:
Push all branches
git config --global push.default matching
It will push all the branches to the remote branch and would merge them.
If you don't want to push all branches, you can push the current branch if you fully specify its name, but this is much is not different from default
.
Push only the current branch if its named upstream is identical
git config --global push.default simple
So, it's better, in my opinion, to use this option and push your code branch by branch. It's better to push branches manually and individually.
Here are my observation, firstly you need to include the header math.h
as sqrt()
function declared in math.h
header file. For e.g
#include <math.h>
secondly, if you read manual page of sqrt you will notice this line Link with -lm.
#include <math.h> /* header file you need to include */
double sqrt(double x); /* prototype of sqrt() function */
Link with -lm. /* Library linking instruction */
But application still says undefined reference to sqrt. Do you see any problem here?
Compiler error is correct as you haven't linked your program with library lm
& linker is unable to find reference of sqrt()
, you need to link it explicitly. For e.g
gcc -Wall -Wextra -Werror -pedantic test.c -lm
Python don't have a great support for recursion because of it's lack of TRE (Tail Recursion Elimination).
This means that each call to your recursive function will create a function call stack and because there is a limit of stack depth (by default is 1000) that you can check out by sys.getrecursionlimit
(of course you can change it using sys.setrecursionlimit but it's not recommended) your program will end up by crashing when it hits this limit.
As other answer has already give you a much nicer way for how to solve this in your case (which is to replace recursion by simple loop) there is another solution if you still want to use recursion which is to use one of the many recipes of implementing TRE in python like this one.
N.B: My answer is meant to give you more insight on why you get the error, and I'm not advising you to use the TRE as i already explained because in your case a loop will be much better and easy to read.
In my case I had gulp-watch running that caused the problems. After stopping it I could execute Cleanup command.

You can maintain the position of the model window when the users scrolls by adding this event to your dialog. This will change it from absolutely positioned to fixed. No need to monitor scrolling events.
open: function(event, ui) {
$(this).parent().css('position', 'fixed');
}
Update: If you are using CLion 2020.2, then it already supports Makefiles. If you are using an older version, read on.
Even though currently only CMake is supported, you can instruct CMake to call make
with your custom Makefile
. Edit your CMakeLists.txt
adding one of these two commands:
When you tell CLion
to run your program, it will try to find an executable with the same name of the target in the directory pointed by PROJECT_BINARY_DIR
. So as long as your make
generates the file where CLion
expects, there will be no problem.
Here is a working example:
CLion
to pass its $(PROJECT_BINARY_DIR) to make
This is the sample CMakeLists.txt
:
cmake_minimum_required(VERSION 2.8.4)
project(mytest)
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11")
add_custom_target(mytest COMMAND make -C ${mytest_SOURCE_DIR}
CLION_EXE_DIR=${PROJECT_BINARY_DIR})
CLion's
directoryThis is the sample Makefile
:
all:
echo Compiling $(CLION_EXE_DIR)/$@ ...
g++ mytest.cpp -o $(CLION_EXE_DIR)/mytest
That is all, you may also want to change your program's working directory so it executes as it is when you run make from inside your directory. For this edit: Run -> Edit Configurations ... -> mytest -> Working directory
It seems that I found a solution to my problem. Very good explanations are given here and here. Here is my example:
pulic class MyActivity extends FragmentActivity{
private ViewPager pager;
private TitlePageIndicator indicator;
private TabsAdapter adapter;
private Bundle savedInstanceState;
@Override
public void onCreate(Bundle savedInstanceState) {
....
this.savedInstanceState = savedInstanceState;
pager = (ViewPager) findViewById(R.id.pager);;
indicator = (TitlePageIndicator) findViewById(R.id.indicator);
adapter = new TabsAdapter(getSupportFragmentManager(), false);
if (savedInstanceState == null){
adapter.addFragment(new FirstFragment());
adapter.addFragment(new SecondFragment());
}else{
Integer count = savedInstanceState.getInt("tabsCount");
String[] titles = savedInstanceState.getStringArray("titles");
for (int i = 0; i < count; i++){
adapter.addFragment(getFragment(i), titles[i]);
}
}
indicator.notifyDataSetChanged();
adapter.notifyDataSetChanged();
// push first task
FirstTask firstTask = new FirstTask(MyActivity.this);
// set first fragment as listener
firstTask.setTaskListener((TaskListener) getFragment(0));
firstTask.execute();
}
private Fragment getFragment(int position){
return savedInstanceState == null ? adapter.getItem(position) : getSupportFragmentManager().findFragmentByTag(getFragmentTag(position));
}
private String getFragmentTag(int position) {
return "android:switcher:" + R.id.pager + ":" + position;
}
@Override
protected void onSaveInstanceState(Bundle outState) {
super.onSaveInstanceState(outState);
outState.putInt("tabsCount", adapter.getCount());
outState.putStringArray("titles", adapter.getTitles().toArray(new String[0]));
}
indicator.setOnPageChangeListener(new ViewPager.OnPageChangeListener() {
@Override
public void onPageSelected(int position) {
Fragment currentFragment = adapter.getItem(position);
((Taskable) currentFragment).executeTask();
}
@Override
public void onPageScrolled(int i, float v, int i1) {}
@Override
public void onPageScrollStateChanged(int i) {}
});
The main idea in this code is that, while running your application normally, you create new fragments and pass them to the adapter. When you are resuming your application fragment manager already has this fragment's instance and you need to get it from fragment manager and pass it to the adapter.
UPDATE
Also, it is a good practice when using fragments to check isAdded before getActivity() is called. This helps avoid a null pointer exception when the fragment is detached from the activity. For example, an activity could contain a fragment that pushes an async task. When the task is finished, the onTaskComplete listener is called.
@Override
public void onTaskComplete(List<Feed> result) {
progress.setVisibility(View.GONE);
progress.setIndeterminate(false);
list.setVisibility(View.VISIBLE);
if (isAdded()) {
adapter = new FeedAdapter(getActivity(), R.layout.feed_item, result);
list.setAdapter(adapter);
adapter.notifyDataSetChanged();
}
}
If we open the fragment, push a task, and then quickly press back to return to a previous activity, when the task is finished, it will try to access the activity in onPostExecute() by calling the getActivity() method. If the activity is already detached and this check is not there:
if (isAdded())
then the application crashes.
If you need to interact directly with the DOM element, why not just use document.getElementById
since, if you are trying to interact with a specific element you will probably know the id, as assuming that the classname is on only one element or some other option tends to be risky.
But, I tend to agree with the others, that in most cases you should learn to do what you need using what jQuery gives you, as it is very flexible.
UPDATE: Based on a comment: Here is a post with a nice explanation: http://www.mail-archive.com/[email protected]/msg04461.html
$(this).attr("checked") ? $(this).val() : 0
This will return the value if it's checked, or 0 if it's not.
$(this).val()
is just reaching into the dom and getting the attribute "value" of the element, whether or not it's checked.
You can use the pattern
attribute. The required
attribute is also needed, otherwise an input field with an empty value will be excluded from constraint validation.
<input pattern=".{3,}" required title="3 characters minimum">
<input pattern=".{5,10}" required title="5 to 10 characters">
If you want to create the option to use the pattern for "empty, or minimum length", you could do the following:
<input pattern=".{0}|.{5,10}" required title="Either 0 OR (5 to 10 chars)">
<input pattern=".{0}|.{8,}" required title="Either 0 OR (8 chars minimum)">
You should be able to rebase your branch on master:
git checkout feature1
git rebase master
Manage all conflicts that arise. When you get to the commits with the bugfixes (already in master), Git will say that there were no changes and that maybe they were already applied. You then continue the rebase (while skipping the commits already in master) with
git rebase --skip
If you perform a git log
on your feature branch, you'll see the bugfix commit appear only once, and in the master portion.
For a more detailed discussion, take a look at the Git book documentation on git rebase
(https://git-scm.com/docs/git-rebase) which cover this exact use case.
================ Edit for additional context ====================
This answer was provided specifically for the question asked by @theomega, taking his particular situation into account. Note this part:
I want to prevent [...] commits on my feature branch which have no relation to the feature implementation.
Rebasing his private branch on master is exactly what will yield that result. In contrast, merging master into his branch would precisely do what he specifically does not want to happen: adding a commit that is not related to the feature implementation he is working on via his branch.
To address the users that read the question title, skip over the actual content and context of the question, and then only read the top answer blindly assuming it will always apply to their (different) use case, allow me to elaborate:
git merge master
as in @Sven's answer).Finally, if you're unhappy with the fact that this answer is not the best fit for your situation even though it was for @theomega, adding a comment below won't be particularly helpful: I don't control which answer is selected, only @theomega does.

I had the same issue, however DoEvents didn't help me as my data connections had background-refresh enabled. Instead, using Wayne G. Dunn's answer as a jumping-off point, I created the following solution, which works just fine for me;
Sub Refresh_All_Data_Connections()
For Each objConnection In ThisWorkbook.Connections
'Get current background-refresh value
bBackground = objConnection.OLEDBConnection.BackgroundQuery
'Temporarily disable background-refresh
objConnection.OLEDBConnection.BackgroundQuery = False
'Refresh this connection
objConnection.Refresh
'Set background-refresh value back to original value
objConnection.OLEDBConnection.BackgroundQuery = bBackground
Next
MsgBox "Finished refreshing all data connections"
End Sub
The MsgBox is for testing only and can be removed once you're happy the code waits.
Also, I prefer ThisWorkbook to ActiveWorkbook as I know it will target the workbook where the code resides, just in case focus changes. Nine times out of ten this won't matter, but I like to err on the side of caution.
EDIT: Just saw your edit about using an xlConnectionTypeXMLMAP connection which does not have a BackgroundQuery option, sorry. I'll leave the above for anyone (like me) looking for a way to refresh OLEDBConnection types.
Please try adding the double quotes git commit -m "initial commit". This will solve your problem.
I answer this coming from a component-based architecture, where an organisation may be running many components that may rely on each other. During a propagating failure, logging levels should help to identify both which components are affected and which are a root cause.
ERROR - This component has had a failure and the cause is believed to be internal (any internal, unhandled exception, failure of encapsulated dependency... e.g. database, REST example would be it has received a 4xx error from a dependency). Get me (maintainer of this component) out of bed.
WARN - This component has had a failure believed to be caused by a dependent component (REST example would be a 5xx status from a dependency). Get the maintainers of THAT component out of bed.
INFO - Anything else that we want to get to an operator. If you decide to log happy paths then I recommend limiting to 1 log message per significant operation (e.g. per incoming http request).
For all log messages be sure to log useful context (and prioritise on making messages human readable/useful rather than having reams of "error codes")
A nice way to visualise the above logging levels is to imagine a set of monitoring screens for each component. When all running well they are green, if a component logs a WARNING then it will go orange (amber) if anything logs an ERROR then it will go red.
In the event of an incident you should have one (root cause) component go red and all the affected components should go orange/amber.
Use array-like fields:
<input name="name_for_the_items[]"/>
You can loop through the fields:
foreach($_POST['name_for_the_items'] as $item)
{
//do something with $item
}
