Check whether you have matching IDs in both Java and XML
You must change the cmake C/CXX default FLAGS .
According to CMAKE_BUILD_TYPE={DEBUG/MINSIZEREL/RELWITHDEBINFO/RELEASE}
put in the main CMakeLists.txt
one of :
For C
set(CMAKE_C_FLAGS_DEBUG "put your flags")
set(CMAKE_C_FLAGS_MINSIZEREL "put your flags")
set(CMAKE_C_FLAGS_RELWITHDEBINFO "put your flags")
set(CMAKE_C_FLAGS_RELEASE "put your flags")
For C++
set(CMAKE_CXX_FLAGS_DEBUG "put your flags")
set(CMAKE_CXX_FLAGS_MINSIZEREL "put your flags")
set(CMAKE_CXX_FLAGS_RELWITHDEBINFO "put your flags")
set(CMAKE_CXX_FLAGS_RELEASE "put your flags")
This will override the values defined in CMakeCache.txt
Please note that android:windowSoftInputMode="adjustResize"
does not work when WindowManager.LayoutParams.FLAG_FULLSCREEN
is set for an activity. You've got two options.
Either disable fullscreen mode for your activity. Activity is not re-sized in fullscreen mode. You can do this either in xml (by changing the theme of the activity) or in Java code. Add the following lines in your onCreate() method.
getWindow().addFlags(WindowManager.LayoutParams.FLAG_FORCE_NOT_FULLSCREEN);
getWindow().clearFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);`
OR
Use an alternative way to achieve fullscreen mode. Add the following code in your onCreate() method.
getWindow().addFlags(WindowManager.LayoutParams.FLAG_FORCE_NOT_FULLSCREEN);
getWindow().clearFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);
getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_ADJUST_RESIZE);
View decorView = getWindow().getDecorView();
// Hide the status bar.
int uiOptions = View.SYSTEM_UI_FLAG_FULLSCREEN;
decorView.setSystemUiVisibility(uiOptions);`
Please note that method-2 only works in Android 4.1 and above.
func readToDisplayUsingFile1(f *os.File){
defer f.Close()
reader := bufio.NewReader(f)
contents, _ := ioutil.ReadAll(reader)
lines := strings.Split(string(contents), '\n')
}
or
func readToDisplayUsingFile1(f *os.File){
defer f.Close()
slice := make([]string,0)
reader := bufio.NewReader(f)
for{
str, err := reader.ReadString('\n')
if err == io.EOF{
break
}
slice = append(slice, str)
}
Here is a sample XAML
that will allow TextBox
to accept multiline text and it uses its own scrollbars:
<TextBox
Height="200"
Width="500"
TextWrapping="Wrap"
AcceptsReturn="True"
HorizontalScrollBarVisibility="Disabled"
VerticalScrollBarVisibility="Auto"/>
While the question does say 'Selectable' I believe the intentional results is to get the text to the clipboard. This can easily and elegantly be achieved by adding a Context Menu and menu item called copy that puts the Textblock Text property value in clipboard. Just an idea anyway.
ES6 Update - ES6 (ES2015 specification) allows for default parameters
The following will work just fine in an ES6 (ES015) environment...
function(nodeBox, str="hai")

}
Update 1: There is a CSS3 spec for CSS level 3 nesting. It's currently a draft. https://tabatkins.github.io/specs/css-nesting/
Update 2 (2019): We now have a CSSWG draft https://drafts.csswg.org/css-nesting-1/
If approved, the syntax would look like this:
table.colortable {
& td {
text-align:center;
&.c { text-transform:uppercase }
&:first-child, &:first-child + td { border:1px solid black }
}
& th {
text-align:center;
background:black;
color:white;
}
}
.foo {
color: red;
@nest & > .bar {
color: blue;
}
}
.foo {
color: red;
@nest .parent & {
color: blue;
}
}
Status: The original 2015 spec proposal was not approved by the Working Group.
Beware of adding 3600!! may be a problem on day change because of unix timestamp format uses moth before day.
e.g. 2012-03-02 23:33:33 would become 2014-01-13 13:00:00 by adding 3600 better use mktime and date functions they can handle this and things like adding 25 hours etc.
There's a theme available specifically for this
options: {
theme: 'maximized'
}
from the Google chart docs:
Currently only one theme is available:
'maximized' - Maximizes the area of the chart, and draws the legend and all of the labels inside the chart area. Sets the following options:
chartArea: {width: '100%', height: '100%'},
legend: {position: 'in'},
titlePosition: 'in', axisTitlesPosition: 'in',
hAxis: {textPosition: 'in'}, vAxis: {textPosition: 'in'}
You can use SET ECHO ON
in the beginning of your script to achieve that, however, you have to specify your script using @
instead of <
(also had to add EXIT
at the end):
test.sql
SET ECHO ON
SELECT COUNT(1) FROM dual;
SELECT COUNT(1) FROM (SELECT 1 FROM dual UNION SELECT 2 FROM dual);
EXIT
terminal
sqlplus hr/oracle@orcl @/tmp/test.sql > /tmp/test.log
test.log
SQL> SQL> SELECT COUNT(1) FROM dual; COUNT(1) ---------- 1 SQL> SQL> SELECT COUNT(1) FROM (SELECT 1 FROM dual UNION SELECT 2 FROM dual); COUNT(1) ---------- 2 SQL> SQL> EXIT
The easiest way I've found for a global association is simply to ctrl+k m (or ctrl+shift+p and type "change language mode") with a file of the type you're associating open.
In the first selections will be "Configure File Association for 'x' " (whatever file type - see image attached) Selecting this makes the filetype association permanent
This may have changed (probably did) since the original question and accepted answer (and I don't know when it changed) but it's so much easier than the manual editing steps in the accepted and some of the other answers, and totaly avoids having to muss with IDs that may not be obvious.

If you don't want to import math, you could use:

Here's a piece of documentation:
>>> help(round)
Help on built-in function round in module __builtin__:

round(number[, ndigits]) -> floating point number
Round a number to a given precision in decimal digits (default 0 digits).
This always returns a floating point number. Precision may be negative.
(for fellow googlers, copied from duplicate question) This answer is outdated since text-decoration-color is now supported by most modern browsers.
You can do this via the following CSS rule as an example:
text-decoration-color:green
If this rule isn't supported by an older browser, you can use the following solution:
Setting your word with a border-bottom:
a:link {
color: red;
text-decoration: none;
border-bottom: 1px solid blue;
}
a:hover {
border-bottom-color: green;
}
You want to implement Comparable, not Comparator. You need to implement the compareTo method. You're close though. Comparator is a "3rd party" comparison routine. Comparable is that this object can be compared with another.
public int compareTo(Object obj1) {
People that = (People)obj1;
Integer p1 = this.getId();
Integer p2 = that.getid();
if (p1 > p2 ){
return 1;
}
else if (p1 < p2){
return -1;
}
else
return 0;
}
Note, you may want to check for nulls in here for getId..just in case.
Old question but throwing my solution into the ring for completeness. I needed this when I needed a specific find but a different create if it doesn't exist.
def self.find_by_or_create_with(args, attributes) # READ CAREFULLY! args for finding, attributes for creating!
obj = self.find_or_initialize_by(args)
return obj if obj.persisted?
return obj if obj.update_attributes(attributes)
end
Please show us more parts of the script and tell us what commands you had to individually execute and want to simply.
Meanwhile you have to use double quotes not single quote to expand variables:
export PATH="/home/linux/Practise/linux-devkit/bin/:$PATH"
Semicolons at the end of a single command are also unnecessary.
So far:
#!/bin/sh
echo "Perform Operation in su mode"
export ARCH=arm
echo "Export ARCH=arm Executed"
export PATH="/home/linux/Practise/linux-devkit/bin/:$PATH"
echo "Export path done"
export CROSS_COMPILE='/home/linux/Practise/linux-devkit/bin/arm-arago-linux-gnueabi-' ## What's next to -?
echo "Export CROSS_COMPILE done"
# continue your compilation commands here
...
For su
you can run it with:
su -c 'sh /path/to/script.sh'
Note: The OP was not explicitly asking for steps on how to create export variables in an interactive shell using a shell script. He only asked his script to be assessed at most. He didn't mention details on how his script would be used. It could have been by using .
or source
from the interactive shell. It could have been a standalone scipt, or it could have been source
'd from another script. Environment variables are not specific to interactive shells. This answer solved his problem.
Quick answer without seeing examples of your current HTML and CSS is to use z-index
css:
#div1 {
position: relative;
z-index: 1;
}
#div2 {
position: relative;
z-index: 2;
}
Where div2 is the overlay
Use option bty = "n"
in legend
to remove the box around the legend. For example:
legend(1, 5,
"This legend text should not be disturbed by the dotted grey lines,\nbut the plotted dots should still be visible",
bty = "n")
Syntax errors is not checked easily in external servers, just runtime errors.
What I do? Just like you, I use
ini_set('display_errors', 'On');
error_reporting(E_ALL);
However, before run I check syntax errors in a PHP file using an online PHP syntax checker.
The best, IMHO is PHP Code Checker
I copy all the source code, paste inside the main box and click the Analyze
button.
It is not the most practical method, but the 2 procedures are complementary and it solves the problem completely
How about using regex?
String firstWord = filename.replaceAll("\\..*","")
This replaces everything from the first dot to the end with "" (ie it clears it, leaving you with what you want)
Here's a test:
System.out.println("abc.def.hij".replaceAll("\\..*", "");
Output:
abc
You might want to take a look at the cmdlet Tee-Object. You can pipe output to Tee and it will write to the pipeline and also to a file
To get the current time in the local timezone as a naive datetime object:
from datetime import datetime
naive_dt = datetime.now()
If it doesn't return the expected time then it means that your computer is misconfigured. You should fix it first (it is unrelated to Python).
To get the current time in UTC as a naive datetime object:
naive_utc_dt = datetime.utcnow()
To get the current time as an aware datetime object in Python 3.3+:
from datetime import datetime, timezone
utc_dt = datetime.now(timezone.utc) # UTC time
dt = utc_dt.astimezone() # local time
To get the current time in the given time zone from the tz database:
import pytz
tz = pytz.timezone('Europe/Berlin')
berlin_now = datetime.now(tz)
It works during DST transitions. It works if the timezone had different UTC offset in the past i.e., it works even if the timezone corresponds to multiple tzinfo objects at different times.
You need to set the Format of the DateTimePicker to Custom and then assign the CustomFormat.
Private Sub Form1_Load(sender As System.Object, e As System.EventArgs) Handles MyBase.Load
DateTimePicker1.Format = DateTimePickerFormat.Custom
DateTimePicker1.CustomFormat = "dd/MM/yyyy"
End Sub
Simply add []
to those names like
<input type="text" class="form-control" placeholder="Titel" name="levels[level][]">
<input type="text" class="form-control" placeholder="Titel" name="levels[build_time][]">
Take that template and then you can add those even using a loop.
Then you can add those dynamically as much as you want, without having to provide an index. PHP will pick them up just like your expected scenario example.
Edit
Sorry I had braces in the wrong place, which would make every new value as a new array element. Use the updated code now and this will give you the following array structure
levels > level (Array)
levels > build_time (Array)
Same index on both sub arrays will give you your pair. For example
echo $levels["level"][5];
echo $levels["build_time"][5];
Without knowing exactly what your requirements are, here's what I did to see packts go by from the iPhone: Connect a mac on ethernet, share its network over airport and connect the iPhone to that wireless network. Run Wireshark or Packet Peeper on the mac.

I was also interested in this, so I did a little performance comparison (using perfplot, a pet project of mine). Result:
y = np.bincount(a)
ii = np.nonzero(y)[0]
out = np.vstack((ii, y[ii])).T
is by far the fastest. (Note the log-scaling.)
Code to generate the plot:
import numpy as np
import pandas as pd
import perfplot
from scipy.stats import itemfreq
def bincount(a):
y = np.bincount(a)
ii = np.nonzero(y)[0]
return np.vstack((ii, y[ii])).T
def unique(a):
unique, counts = np.unique(a, return_counts=True)
return np.asarray((unique, counts)).T
def unique_count(a):
unique, inverse = np.unique(a, return_inverse=True)
count = np.zeros(len(unique), np.int)
np.add.at(count, inverse, 1)
return np.vstack((unique, count)).T
def pandas_value_counts(a):
out = pd.value_counts(pd.Series(a))
out.sort_index(inplace=True)
out = np.stack([out.keys().values, out.values]).T
return out
perfplot.show(
setup=lambda n: np.random.randint(0, 1000, n),
kernels=[bincount, unique, itemfreq, unique_count, pandas_value_counts],
n_range=[2 ** k for k in range(26)],
logx=True,
logy=True,

My problem at first was:
Unable to execute dex: java.nio.BufferOverflowException. Check the Eclipse log for stack trace.
1) I Right click on my project -> Android Tools -> Add Support Library (Run my app...Didn't work so I keep it going...) 2) Right click on my project again -> Properties -> Android -> Check Android 4.1.2 (16) on Project Build Target (Run the app again...and get this:

3) So I went to the "lib" folder on my project and delete the "old" Android.support.library.jar (Run the app and cross fingers and...)
¡IT WORKS!

As far as I can tell, it no longer is possible in Chrome or FireFox. It may still be possible in IE (at least pre-Edge).
This is rather an old question, but I will add my notes for future references.
I had a similar issue and fixed it by changing the order of the exports in the PATH variable.
For example I was using a method of concatenating strings to my PATH by doing (this is just an example):
$> export PATH='$PATH:'$JAVA_HOME
If my variable PATH already had a java in it, the last value would be meaningless, thus the order would matter. To solve this I started inverting it by adding my variable first, then adding the PATH.
Following this idea I inverted the order that ANT_HOME was being exported. Adding JAVA_HOME before ANT_HOME.
This could be just a coincidence, but it worked for me.

For changing data type
alter table table_name
alter column column_name datatype [NULL|NOT NULL]
For changing Primary key
ALTER TABLE table_name
ADD CONSTRAINT PK_MyTable PRIMARY KEY (column_name)
I had this very similar error as following.
C:\wamp\www\myrepository [master]> git push
fatal: unable to access 'https://github.com/myaccount/myrepository.git/': Couldn't resolve host 'github.com'
Actually, the prompt message has told us where's wrong.
https://github.com/myaccount/myrepository.git/
When I check my github, I found my github repository's HTTPS url is
https://github.com/myaccount/myrepository.git
I don't know how this happened. The wrong url has been set up by installed Git Shell automatically.
Once I remove the '/' at the end, I can push successfully.
For only validating syntax:
shellcheck [programPath]
For running the program only if syntax passes, so debugging both syntax and execution:
shellproof [programPath]
The idea that you hope to achieve can be made possible if you tweak the requirement a little bit

Security Warning:
md5(uniqid(rand(), TRUE))
is not a secure way to generate random numbers. See this answer for more information and a solution that leverages a cryptographically secure random number generator.
Looks like you need an else with your if.
if (!isset($_SESSION['token'])) {
$token = md5(uniqid(rand(), TRUE));
$_SESSION['token'] = $token;
$_SESSION['token_time'] = time();
}
else
{
$token = $_SESSION['token'];
}
Simply add the following fields in your .plist file

<dict>
<key>NSAllowsArbitraryLoads</key>
<true/>

Since this only came up hidden in comments, difficult to find as a solution:
You can use java -Dhttps.protocols=TLSv1,TLSv1.1
, but you need to use also useSystemProperties()
client = HttpClientBuilder.create().useSystemProperties();
We use this setup in our system now as this enables us to set this only for some usage of the code.
In our case we still have some Java 7 running and one API end point disallowed TLSv1,
so we use java -Dhttps.protocols=TLSv1,TLSv1.1,TLSv1.2
to enable current TLS versions.
Thanks @jebeaudet for pointing in this direction.
Here it is a simpler way to achieve that:
#outer{
display: table;
}
#inner {
display: table-cell;
float: none;
}

I solved it in two steps. To rename folder using mv command you need rights to do so, if you don't have right you can follow these steps. Suppose you want to rename casesensitive to Casesensitive.
Step 1: Rename the folder (casesensitive) to something else from explorer. eg Rename casesensitive to folder1 commit this change.
Step 2: Rename this newly named folder(folder1) to the expected case sensitive name (Casesensitive ) eg. Rename folder1 to Casesensitive. Commit this change.
You need to return your promise to the calling function.

$checkSessionServer.then(function(){
alert("session check returned!");
console.log("checkSessionServer is "+$checkSessionServer);
});
return $checkSessionServer; // <-- return your promise to the calling function

Not calling Close
probably bypasses sending a bunch of Win32 messages which one would think are somewhat important though I couldn't specifically tell you why...
Close
has the benefit of raising events (that can be cancelled) such that an outsider (to the form) could watch for FormClosing
and FormClosed
in order to react accordingly.
I'm not clear whether FormClosing
and/or FormClosed
are raised if you simply dispose the form but I'll leave that to you to experiment with.
What...
A methodology for automaticaly testing code against a battery of tests, designed to enforce desired outcomes and manage change.
A "unit" in this sense is the smallest atomic component of the code that makes sense to test, typically a method of some class for example. Part of this process is building up stub objects (or "mocks") which allow you to work with a unit as an independant object.
How...
Almost always, the process of unit-testing is built into an IDE (or through extensions) such that it executes the tests with every compile. A number of frameworks exist for assisting the creation of unit tests (and indeed mock objcts), often named fooUnit (cf. jUnit, xUnit, nUnit). These frameworks provide a formalised way to create tests.
As a process, test driven development (TDD) is often the motivation for unit testing (but unit testing does not require TDD) which supposes that the tests are a part of the spec definition, and therefore requires that they are written first, with code only written to "solve" these tests.
When...
Almost always. Very small, throwaway projects may not be worth it, but only if you're quite sure they really are throwaway. In theory every object orientated program is unit testable, but some design pattrns make this difficult. Notoriously, the singleton pattern is problematic, where conversely dependancy injection frameworks are very much unit testing oriented.

Quite frequently when I am creating an XML file from data stored in a class I would frequently receive errors if the attribute didn't exist or was of type None
. In this case, my issue wasn't not knowing what the attribute name was, as stated in your question, but rather was data ever stored in that attribute.
class Pet:
def __init__(self):
self.hair = None
self.color = None
If I used hasattr
to do this, it would return True
even if the attribute value was of type None
and this would cause my ElementTree set
command to fail.
hasattr(temp, 'hair')
>>True
If the attribute value was of type None
, getattr
would also return it which would cause my ElementTree set
command to fail.
c = getattr(temp, 'hair')
type(c)
>> NoneType
I use the following method to take care of these cases now:
def getRealAttr(class_obj, class_attr, default = ''):
temp = getattr(class_obj, class_attr, default)
if temp is None:
temp = default
elif type(temp) != str:
temp = str(temp)
return temp
This is when and how I use getattr
.
If you don't want to use sessions, the only thing you can do is POST to the same page. Which IMO is the best solution anyway.
// form.php
<?php
if (!empty($_POST['submit'])) {
// validate
if ($allGood) {
// put data into database or whatever needs to be done
header('Location: nextpage.php');
exit;
}
}
?>
<form action="form.php">
<input name="foo" value="<?php if (!empty($_POST['foo'])) echo htmlentities($_POST['foo']); ?>">
...
</form>
This can be made more elegant, but you get the idea...

If you are having problems with the above examples on a Windows 10 box, try replacing .CreationTime
with .LastwriteTime
. This worked for me.
dir C:\locationOfFiles -ErrorAction SilentlyContinue | Where { ((Get-Date)-$_.LastWriteTime).days -gt 15 } | Remove-Item -Force
In general, one doesn't expand out log(a + b)
; you just deal with it as is. That said, there are occasionally circumstances where it makes sense to use the following identity:
log(a + b) = log(a * (1 + b/a)) = log a + log(1 + b/a)
(In fact, this identity is often used when implementing log
in math libraries).
For Mac users who want to check whether your processor supports virtualisation, use the maccpuid
software and look for VMX. If it is checked then you're good to go.
If you are using Url.Action
inside JavaScript then you can
var personId="someId";
$.ajax({
type: 'POST',
url: '@Url.Action("CreatePerson", "Person")',
dataType: 'html',
data: ({
//insert your parameters to pass to controller
id: personId
}),
success: function() {
alert("Successfully posted!");
}
});
This is a segfault due to following a null pointer trying to find code to run (that is, during an instruction fetch).
Run addr2line -e yourSegfaultingProgram 00007f9bebcca90d
(and repeat for the other instruction pointer values given) to see where the error is happening. Better, get a debug-instrumented build, and reproduce the problem under a debugger such as gdb.
You're hosed, unfortunately; it's not possible to know where the libraries were placed in memory by the dynamic linker after-the-fact. Reproduce the problem under gdb
.
Here's the breakdown of the fields:
address
(after the at
) - the location in memory the code is trying to access (it's likely that 10
and 11
are offsets from a pointer we expect to be set to a valid value but which is instead pointing to 0
)ip
- instruction pointer, ie. where the code which is trying to do this livessp
- stack pointererror
- An error code for page faults; see below for what this means on x86.
/*
* Page fault error code bits:
*
* bit 0 == 0: no page found 1: protection fault
* bit 1 == 0: read access 1: write access
* bit 2 == 0: kernel-mode access 1: user-mode access
* bit 3 == 1: use of reserved bit detected
* bit 4 == 1: fault was an instruction fetch
*/
give on .view-type
class float:left;
or delete the float:right;
of .view-name
edit: Wrap your div <div class="view-row">
with another div for example <div class="table">
and set the following css :
.table {
display:table;
width:100%;}
You have to use the table structure for correct results.
I would not expect that to work
try instead
window.frames["printf"].focus();
window.frames["printf"].print();
and use
<iframe id="printf" name="printf"></iframe>
Alternatively try good old
var newWin = window.frames["printf"];
newWin.document.write('<body onload="window.print()">dddd</body>');
newWin.document.close();
if jQuery cannot hack it
Apart from the previous answers, you can use df.axes
to get the tuple with row and column indexes and then use the len()
function:
total_rows = len(df.axes[0])
total_cols = len(df.axes[1])
Afaik the Browser application data is NOT clearable for other apps, since it is store in private_mode
. So executing this command could probalby only work on rooted devices. Otherwise you should try another approach.
In addition to the other answers, there is a big benefit to using the DisplayAttribute
when you want to localize the fields. You can lookup the name in a localization database using the DisplayAttribute and it will use whatever translation you wish.
Also, you can let MVC generate the templates for you by using Html.EditorForModel()
and it will generate the correct label for you.
Ultimately, it's up to you. But the MVC is very "Model-centric", which is why data attributes are applied to models, so that metadata exists in a single place. It's not like it's a huge amount of extra typing you have to do.
If using Visual Studio 2010 you can right-click on the project for the service, and select properties
. Then select the Web
tab. Under the Servers
section you can configure the URL. There is also a button to create the virtual directory.
Well I did it this way, as seen on https://nodejs.org/api/fs.html#fs_fs_access_path_mode_callback
fs.access('./settings', fs.constants.F_OK | fs.constants.R_OK | fs.constants.W_OK, function(err){
console.log(err ? 'no access or dir doesnt exist' : 'R/W ok');
if(err && err.code === 'ENOENT'){
fs.mkdir('settings');
}
});
Is there any problem with this?
try .includes()
[1, 2, 3].includes(2); // true
[1, 2, 3].includes(4); // false
[1, 2, 3].includes(3, 3); // false
[1, 2, 3].includes(3, -1); // true
[1, 2, NaN].includes(NaN); // true
so something like
const array = [1, 3];
if (!array.includes(2))
array.push(2);
note the browser compatibility at the bottom of the page, however.
To create a clickable reference to a channel in a Slack conversation, just type #
followed by the channel name. For example: #general
.
To share the channel URL externally, you can grab its link by control-clicking (Mac) or right-clicking (Windows) on the channel name:
The link would look like this:
https://yourteam.slack.com/messages/C69S1L3SS
Note that this link doesn't change even if you change the name of the channel. So, it is better to use this link rather than the one based on channel's name.
https://yourteam.slack.com/channels/<channel_name>
Opening the above URL from a browser would launch the Slack client (if available) or open the slack channel on the browser itself.
https://yourteam.slack.com/channels/<username>
Although alert(msg);
works in those "I just want to find out whats going on" scenarios... every developer has encountered that case where you end up in a (very large or endless) loop that you can't break out of.
I'd recommend that during development if you want a very in-your-face debug option, use a debug option that lets you break out. (PS Opera, Safari? and Chrome? all have this available in their native dialogs)
//global flag
_debug = true;
function debug(msg){
if(_debug){
if(!confirm(msg + '\n\nPress Cancel to stop debugging.')){
_debug = false;
}
}
}
With the above you can get your self into a large loop of popup debugging, where pressing Enter/Ok lets you jump through each message, but pressing Escape/Cancel lets you break out nicely.
UPDATE:
Like @jack-marchetti stated in his comment, and @devantoine with the link: https://developers.facebook.com/x/bugs/357750474364812/
Facebook has changed how the sharer.php works, as Ibrahim Faour replies to the bug filed with Facebook.
The sharer will no longer accept custom parameters and facebook will pull the information that is being displayed in the preview the same way that it would appear on facebook as a post, from the url OG meta tags.
Try this (via Javascript in this example):
'http://www.facebook.com/sharer.php?s=100&p[title]='+encodeURIComponent('this is a title') + '&p[summary]=' + encodeURIComponent('description here') + '&p[url]=' + encodeURIComponent('http://www.nufc.com') + '&p[images][0]=' + encodeURIComponent('http://www.somedomain.com/image.jpg')
I tried this quickly without the image part and the sharer.php window appears pre-populated, so it looks like a solution.
I found this via this SO article:
Want custom title / image / description in facebook share link from a flash app
and this link contained in an answer from Lelis718:
so all credit to Lelis718 for this answer.
[EDIT 3rd May 2013] - seems like the original URL i had here no longer works for me without also including "s=100" in the query string - no idea why but have updated accordingly
Or, if you are using some property from vuejs prototype that can't be read on creation you can also define headers and write i.e.
storePropertyMaxSpeed(){
axios.post('api/property', {
"property_name" : 'max_speed',
"property_amount" : this.newPropertyMaxSpeed
},
{headers : {'Content-Type': 'application/json',
'Authorization': 'Bearer ' + this.$gate.token()}})
.then(() => { //this below peace of code isn't important
Event.$emit('dbPropertyChanged');
$('#addPropertyMaxSpeedModal').modal('hide');
Swal.fire({
position: 'center',
type: 'success',
title: 'Nova brzina unešena u bazu',
showConfirmButton: false,
timer: 1500
})
})
.catch(() => {
Swal.fire("Neuspješno!", "Nešto je pošlo do davola", "warning");
})
}
},
Google has created a library for easy Permissions management. Its called EasyPermissions
Here is a simple example on requesting Location permission using this library.
public class MainActivity extends AppCompatActivity {
private final int REQUEST_LOCATION_PERMISSION = 1;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
requestLocationPermission();
}
@Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
// Forward results to EasyPermissions
EasyPermissions.onRequestPermissionsResult(requestCode, permissions, grantResults, this);
}
@AfterPermissionGranted(REQUEST_LOCATION_PERMISSION)
public void requestLocationPermission() {
String[] perms = {Manifest.permission.ACCESS_FINE_LOCATION};
if(EasyPermissions.hasPermissions(this, perms)) {
Toast.makeText(this, "Permission already granted", Toast.LENGTH_SHORT).show();
}
else {
EasyPermissions.requestPermissions(this, "Please grant the location permission", REQUEST_LOCATION_PERMISSION, perms);
}
}
}
@AfterPermissionsGranted(REQUEST_CODE)
is used to indicate the method that needs to be executed after a permission request with the request code REQUEST_CODE
has been granted.
This above case, the method requestLocationPermission()
method is called if the user grants the permission to access location services. So, that method acts as both a callback and a method to request the permissions.
You can implement separate callbacks for permission granted and permission denied as well. It is explained in the github page.
e.g.
ColorTranslator.ToHtml(Color.FromArgb(Color.Tomato.ToArgb()))
This can avoid the KnownColor trick.
I use a mixture of float and overflow-x:hidden. Minimal code, always works.
https://jsfiddle.net/9934sc4d/4/ - PLUS you don't need to clear your float!
.left-half{
width:200px;
float:left;
}
.right-half{
overflow-x:hidden;
}
Given you're on a rails 3 project with rspec 2, From the rails root directory:
bundle exec rspec spec/controllers/groups_controller_spec.rb
should definitely work. i got tired of typing that so i created an alias to shorten 'bundle exec rspec' to 'bersp'
'bundle exec' is so that it loads the exact gem environment specified in your gem file: http://gembundler.com/
Rspec2 switched from the 'spec' command to the 'rspec' command.
I know pretty well that this question have already been answered and that the OP is already happy with the accepted answer. But I found most of the answers, including the accepted one, to be a little bit more complicated.
I have a project which gave me a situation like this and I was able to achieve it this way.
First, you have to consider the casing of your enum names:
public enum AuthenticationMethod
{
Forms = 1,
WindowsAuthentication = 2,
SingleSignOn = 3
}
Then, have this extension:
using System.Text.RegularExpression;
public static class AnExtension
{
public static string Name(this Enum value)
{
string strVal = value.ToString();
try
{
return Regex.Replace(strVal, "([a-z])([A-Z])", "$1 $2");
}
catch
{
}
return strVal;
}
}
Through this you can turn your every enum name to its string representation with each word separated with a space. Ex:
AuthenticationMethod am = AuthenticationMethod.WindowsAuthentication;
MessageBox.Show(am.Name());
Page Control can be contained in Window Control but vice versa is not possible
You can use Page control within the Window control using NavigationWindow and Frame controls. Window is the root control that must be used to hold/host other controls (e.g. Button) as container. Page is a control which can be hosted in other container controls like NavigationWindow or Frame. Page control has its own goal to serve like other controls (e.g. Button). Page is to create browser like applications. So if you host Page in NavigationWindow, you will get the navigation implementation built-in. Pages are intended for use in Navigation applications (usually with Back and Forward buttons, e.g. Internet Explorer).
WPF provides support for browser style navigation inside standalone application using Page class. User can create multiple pages, navigate between those pages along with data.There are multiple ways available to Navigate through one page to another page.
I received the same error when I tried to call https web service as http webservice.
e.g when I call url 'http://api.example.com/users/get'
which should be 'https://api.example.com/users/get'
This error is produced because of redirection status 302 when you try to call http instead of https.
You can also use sum
, if you give it a start
argument:
>>> list1, list2, list3 = [1,2,3], ['a','b','c'], [7,8,9]
>>> all_lists = sum([list1, list2, list3], [])
>>> all_lists
[1, 2, 3, 'a', 'b', 'c', 7, 8, 9]
This works in general for anything that has the +
operator:
>>> sum([(1,2), (1,), ()], ())
(1, 2, 1)
>>> sum([Counter('123'), Counter('234'), Counter('345')], Counter())
Counter({'1':1, '2':2, '3':3, '4':2, '5':1})
>>> sum([True, True, False], False)
2
With the notable exception of strings:
>>> sum(['123', '345', '567'], '')
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: sum() can't sum strings [use ''.join(seq) instead]
$myarray = array(
'test1' => 'foo',
'test2' => 'bar',
'test3' => 'baz',
'test4' => 'waldo'
);
$myarray2 = array(
'foo',
'bar',
'baz',
'waldo'
);
// Get the last array_key
$last = array_pop(array_keys($myarray));
foreach($myarray as $key => $value) {
if($key != $last) {
echo "$key -> $value\n";
}
}
// Get the last array_key
$last = array_pop(array_keys($myarray2));
foreach($myarray2 as $key => $value) {
if($key != $last) {
echo "$key -> $value\n";
}
}
Since array_pop
works on the temporary array created by array_keys
it doesn't modify the original array at all.
$ php test.php
test1 -> foo
test2 -> bar
test3 -> baz
0 -> foo
1 -> bar
2 -> baz
Rectangle bounds = Screen.GetBounds(Point.Empty);
using(Bitmap bitmap = new Bitmap(bounds.Width, bounds.Height))
{
using(Graphics g = Graphics.FromImage(bitmap))
{
g.CopyFromScreen(Point.Empty, Point.Empty, bounds.Size);
}
bitmap.Save("test.jpg", ImageFormat.Jpeg);
}
for capturing current window use
Rectangle bounds = this.Bounds;
using (Bitmap bitmap = new Bitmap(bounds.Width, bounds.Height))
{
using (Graphics g = Graphics.FromImage(bitmap))
{
g.CopyFromScreen(new Point(bounds.Left,bounds.Top), Point.Empty, bounds.Size);
}
bitmap.Save("C://test.jpg", ImageFormat.Jpeg);
}
Try this may will help you.Go to "File" -> "Invalidate Caches...", and select "Invalidate and Restart" option to fix this.
Using base R aggregate
function:
aggregate(value ~ name, dat1, I)
# name value.1 value.2 value.3 value.4
#1 firstName 0.4145 -0.4747 0.0659 -0.5024
#2 secondName -0.8259 0.1669 -0.8962 0.1681
InvariantCulture
is similar to en-US
, so i would use the correct CultureInfo
instead:
var dutchCulture = CultureInfo.CreateSpecificCulture("nl-NL");
var date1 = DateTime.ParseExact(date, "dd.MM.yyyy HH:mm:ss", dutchCulture);
And what about when the culture is en-us? Will I have to code for every single language there is out there?
If you want to know how to display the date in another culture like "en-us", you can use date1.ToString(CultureInfo.CreateSpecificCulture("en-US"))
.
You could try the fnmatch module, it's got a shell-like wildcard syntax
or can use regular expressions
import re
git.exe is common for any git based applications like GitHub, Bitbucket etc. Some times it is possible that you have already installed another git based application so git.exe will be present in the bin folder of that application.
For example if you installed bitbucket before github in your PC, you will find git.exe in C:\Users\{username}\AppData\Local\Atlassian\SourceTree\git_local\bin
instead of C:\Users\{username}\AppData\Local\GitHub\PortableGit.....\bin
.
Another possibility is too many threads. We just ran into this error message when running a test harness against an app that uses a thread pool. We used
watch -n 5 -d "ps -eL <java_pid> | wc -l"
to watch the ongoing count of Linux native threads running within the given Java process ID. After this hit about 1,000 (for us--YMMV), we started getting the error message you mention.
netstat -ano | findstr <your port number>
showed nothing for me. I found out that port was excluded using this command to see what ranges are reserved by something else:
netsh interface ipv4 show excludedportrange protocol=tcp
You can try to unblock the range from the start port for a number of ports (need Command Prompt with Administrator):
netsh int ip delete excludedportrange protocol=tcp numberofports=<number of ports> startport=<start port>
However, in my case I couldn't unblock the range, I just got "Access is denied", so I ended up having to pick another port for my site.
My original solution: The only thing that worked was deleting the .vs folder in the solution folder. (I've since found you can just delete the .vs/config/applicationhost.config instead to avoid losing so many settings).
this will work as you asked without CHAR(38):
update t set country = 'Trinidad and Tobago' where country = 'trinidad & '|| 'tobago';
create table table99(col1 varchar(40));
insert into table99 values('Trinidad &' || ' Tobago');
insert into table99 values('Trinidad &' || ' Tobago');
insert into table99 values('Trinidad &' || ' Tobago');
insert into table99 values('Trinidad &' || ' Tobago');
SELECT * FROM table99;
update table99 set col1 = 'Trinidad and Tobago' where col1 = 'Trinidad &'||' Tobago';
I was getting this error too, although my issue was that I kept switching between two corporate networks via my Virtual Machine, with different access credentials. I had to run the command prompt:
ipconfig /renew
After this my network issues were resolved and I could connect once again to SQL.
just pass the columnName as parameter of YEAR
SELECT YEAR(ASOFDATE) from PSASOFDATE;
another is to use DATE_FORMAT
SELECT DATE_FORMAT(ASOFDATE, '%Y') from PSASOFDATE;
UPDATE 1
I bet the value is varchar with the format MM/dd/YYYY, it that's the case,
SELECT YEAR(STR_TO_DATE('11/15/2012', '%m/%d/%Y'));
LAST RESORT if all the queries fail
use SUBSTRING
SELECT SUBSTRING('11/15/2012', 7, 4)
You can set it as JVM arguments the usual way, e.g. -Xms1024m -Xmx2048m
for a minimum heap of 1GB and maximum heap of 2GB. JBoss will use the JAVA_OPTS
environment variable to include additional JVM arguments, you could specify it in the /bin/run.conf.bat
file:
set "JAVA_OPTS=%JAVA_OPTS% -Xms1024m -Xmx2048m"
However, this is more a workaround than a real solution. If multiple users concurrently uploads big files, you'll hit the same problem sooner or later. You would need to keep increasing memory for nothing. You should rather configure your file upload parser to store the uploaded file on temp disk instead of entirely in memory. As long as it's unclear which parser you're using, no suitable answer can be given. However, more than often Apache Commons FileUpload is used under the covers, you should then read the documentation with "threshold size" as keyword to configure the memory limit for uploaded files. When the file size is beyond the threshold, it would then be written to disk.
The following will produce, in the output directory,
But it does not contain all .NET Core runtime assemblies.

I wrapped it up in a sample here: https://github.com/SimonCropp/NetCoreConsole
Most likely your query failed, and the query call returned a boolean FALSE (or an error object of some sort), which you then try to use as if was a resultset object, causing the error. Try something like var_dump($result)
to see what you really got.
Check for errors after EVERY database query call. Even if the query itself is syntactically valid, there's far too many reasons for it to fail anyways - checking for errors every time will save you a lot of grief at some point.
Current version 1.4.0 has clearBtn
option:
$('.datepicker').datepicker({
clearBtn: true
});
Besides adding button to interface it allows to delete value from input box manually.
It looks like you are trying to start the Python interpreter by running the command python
.
However the interpreter is already started. It is interpreting python
as a name of a variable, and that name is not defined.
Try this instead and you should hopefully see that your Python installation is working as expected:
print("Hello world!")
This is strictly not speaking using jQuery, but I have found this method easier than using jQuery. There are probably endless methods of achieving this and many clever ones here, but not all have worked for me. However the following method has always worked and I am passing it one in case it helps someone else.
Three javascript libraries are required, createCookie
, readCookie
and eraseCookie
. These libraries are not mine but I began using them about 5 years ago and don't know their origin.
createCookie = function(name, value, days) {
if (days) {
var date = new Date();
date.setTime(date.getTime() + (days * 24 * 60 * 60 * 1000));
var expires = "; expires=" + date.toGMTString();
}
else var expires = "";
document.cookie = name + "=" + value + expires + "; path=/";
}
readCookie = function (name) {
var nameEQ = name + "=";
var ca = document.cookie.split(';');
for (var i = 0; i < ca.length; i++) {
var c = ca[i];
while (c.charAt(0) == ' ') c = c.substring(1, c.length);
if (c.indexOf(nameEQ) == 0) return c.substring(nameEQ.length, c.length);
}
return null;
}
eraseCookie = function (name) {
createCookie(name, "", -1);
}
To call them you need to create a small PHP function, normally as part of your support library, as follows:
<?php
function createjavaScriptCookie($sessionVarible) {
$s = "<script>";
$s = $s.'createCookie('. '"'. $sessionVarible
.'",'.'"'.$_SESSION[$sessionVarible].'"'. ',"1"'.')';
$s = $s."</script>";
echo $s;
}
?>
So to use all you now have to include within your index.php file is
$_SESSION["video_dir"] = "/video_dir/";
createjavaScriptCookie("video_dir");
Now in your javascript library.js you can recover the cookie with the following code:
var videoPath = readCookie("video_dir") +'/'+ video_ID + '.mp4';
I hope this helps.
For a good quality x264 encoding of 1060i, done by a computer, not a mobile device, not in real time, you could use a bitrate at about 5 MBps. That means 2250 MB/hour of encoded material. Recommend you deinterlace the footage and compress as progressive.
if (-not ([string]::IsNullOrEmpty($version)))
{
$request += "/" + $version
}
You can also use !
as an alternative to -not
.
One feature of the DataSet is that if you can call multiple select statements in your stored procedures, the DataSet will have one DataTable for each.
Another way to insert text from a textarea in the DOM keeping the line breaks is to use the Node.innerText property that represents the rendered text content of a node and its descendants.
As a getter, it approximates the text the user would get if they highlighted the contents of the element with the cursor and then copied to the clipboard.
The property became standard in 2016 and is well supported by modern browsers. Can I Use: 97% global coverage when I posted this answer.
My conclusion is HTML doesn't allows NESTED SCRIPT tags. If you are using javascript for injecting HTML code that include script tags inside is not going to work because the javascript goes in a script tag too. You can test it with the next code and you will be that it's not going to work. The use case is you are calling a service with AJAX or similar, you are getting HTML and you want to inject it in the HTML DOM straight forward. If the injected HTML code has inside SCRIPT tags is not going to work.
<!DOCTYPE html><html lang="en"><head><meta charset="utf-8"></head><body></body><script>document.getElementsByTagName("body")[0].innerHTML = "<script>console.log('hi there')</script>\n<div>hello world</div>\n"</script></html>
You can use
start "" "%USERPROFILE%\Desktop\BGInfo\bginfo.exe" "%USERPROFILE%\Desktop\BGInfo\dc_bginfo.bgi"
or
start "" /D "%USERPROFILE%\Desktop\BGInfo" bginfo.exe dc_bginfo.bgi
or
"%USERPROFILE%\Desktop\BGInfo\bginfo.exe" "%USERPROFILE%\Desktop\BGInfo\dc_bginfo.bgi"
or
cd /D "%USERPROFILE%\Desktop\BGInfo"
bginfo.exe dc_bginfo.bgi
Help on commands start and cd is output by executing in a command prompt window help start
or start /?
and help cd
or cd /?
.
But I do not understand why you need a batch file at all for starting the application with the additional parameter. Create a shortcut (*.lnk) on your desktop for this application. Then right click on the shortcut, left click on Properties and append after a space character "%USERPROFILE%\Desktop\BGInfo\dc_bginfo.bgi"
as parameter.
SIMPLIEST WAY TO HANDLE TIMEOUT LOOP
function myFunc (terminator = false) {
if(terminator) {
clearTimeout(timeOutVar);
} else {
// do something
timeOutVar = setTimeout(function(){myFunc();}, 1000);
}
}
myFunc(true); // -> start loop
myFunc(false); // -> end loop
I see two options here
var link = $('a').attr('href');
var equalPosition = link.indexOf('='); //Get the position of '='
var number = link.substring(equalPosition + 1); //Split the string and get the number.
I dont know if you're gonna use it for paging and have the text in the <a>
-tag as you have it, but if you should you can also do
var number = $('a').text();
There is a way of displaying 3 Y axis see here.
Excel supports Secondary Axis, i.e. only 2 Y axis. Other way would be to chart the 3rd one separately, and overlay on top of the main chart.
All the above answers are good. Here's a simple little code snippet, to illustrate the difference. Try it with each of the values of true and false in setDaemon
.
public class DaemonTest {
public static void main(String[] args) {
new WorkerThread().start();
try {
Thread.sleep(7500);
} catch (InterruptedException e) {
// handle here exception
}
System.out.println("Main Thread ending") ;
}
}
class WorkerThread extends Thread {
public WorkerThread() {
// When false, (i.e. when it's a non daemon thread),
// the WorkerThread continues to run.
// When true, (i.e. when it's a daemon thread),
// the WorkerThread terminates when the main
// thread or/and user defined thread(non daemon) terminates.
setDaemon(true);
}
public void run() {
int count = 0;
while (true) {
System.out.println("Hello from Worker "+count++);
try {
sleep(5000);
} catch (InterruptedException e) {
// handle exception here
}
}
}
}
So
I needed to use addOnGlobalLayoutListener to get the appropriate sample
for example, your Google Map is inside RelativeLayout:
RelativeLayout mapLayout = (RelativeLayout)findViewById(R.id.map_layout);
mapLayout.getViewTreeObserver().addOnGlobalLayoutListener(new OnGlobalLayoutListener() {
@Override
public void onGlobalLayout() {
//and write code, which you can see in answer above
}
});
This answer is similar to the accepted one, but a bit less convoluted.
L<-list()
for (i in 1:3) {
L<-c(L, list(list(sample(1:3))))

To create an XMLdocument in PHP you should instance a DOMDocument class, create child nodes and append these nodes in the correct branch of the document tree.
For reference you can read http://it.php.net/manual/en/book.dom.php
Now we will take a quick tour of the code below.
These are the basics, you can create and append a node in just a line (13th, for example), you can do a lot of other things with the dom api. It is up to you.
<?php
/* create a dom document with encoding utf8 */
$domtree = new DOMDocument('1.0', 'UTF-8');
/* create the root element of the xml tree */
$xmlRoot = $domtree->createElement("xml");
/* append it to the document created */
$xmlRoot = $domtree->appendChild($xmlRoot);
$currentTrack = $domtree->createElement("track");
$currentTrack = $xmlRoot->appendChild($currentTrack);
/* you should enclose the following two lines in a cicle */
$currentTrack->appendChild($domtree->createElement('path','song1.mp3'));
$currentTrack->appendChild($domtree->createElement('title','title of song1.mp3'));
$currentTrack->appendChild($domtree->createElement('path','song2.mp3'));
$currentTrack->appendChild($domtree->createElement('title','title of song2.mp3'));
/* get the xml printed */
echo $domtree->saveXML();
?>
Edit: Just one other hint: The main advantage of using an xmldocument (the dom document one or the simplexml one) instead of printing the xml,is that the xmltree is searchable with xpath query
DefaultForeColor is enough for this statement. This property gets the default foreground color of the control.

There are Python libraries that can recognize files based on their content (usually a header / magic number) and that don't rely on the file name or extension.
If you're addressing many different file types, you can use python-magic
. That's just a Python binding for the well-established magic
library. This has a good reputation and (small endorsement) in the limited use I've made of it, it has been solid.
There are also libraries for more specialized file types. For example, the Python standard library has the imghdr
module that does the same thing just for image file types.
If you need dependency-free (pure Python) file type checking, see filetype
.
For simple document, I sometimes use verbatim, but listing is nice for big chunk of code.
There are many ways of doing this (and I encourage you to look them up as they will be more efficient generally) but the simplest way of doing this is to use a non-set operation to define the value of the third column:
SELECT
t1.previous
,t1.present
,(t1.present - t1.previous) as difference
FROM #TEMP1 t1
Note, this style of selection is considered bad practice because it requires the query plan to reselect the value of the first two columns to logically determine the third (a violation of set theory that SQL is based on). Though it is more complicated, if you plan on using this to evaluate more than the values you listed in your example, I would investigate using an APPLY clause. http://technet.microsoft.com/en-us/library/ms175156(v=sql.105).aspx
It is correct, but perhaps not useful.
As there is nothing to wait on – no calls to blocking APIs which could operate asynchronously – then you are setting up structures to track asynchronous operation (which has overhead) but then not making use of that capability.
For example, if the service layer was performing DB operations with Entity Framework which supports asynchronous calls:
public Task<BackOfficeResponse<List<Country>>> ReturnAllCountries()
{
using (db = myDBContext.Get()) {
var list = await db.Countries.Where(condition).ToListAsync();
return list;
}
}
You would allow the worker thread to do something else while the db was queried (and thus able to process another request).
Await tends to be something that needs to go all the way down: it is very hard to retro-fit into an existing system.
string cannot be the parameter to Nullable because string is not a value type. String is a reference type.
string s = null;
is a very valid statement and there is not need to make it nullable.
private string typeOfContract
{
get { return ViewState["typeOfContract"] as string; }
set { ViewState["typeOfContract"] = value; }
}
should work because of the as keyword.

Starting with Postgres 10, identity columns as defined by the SQL standard are also supported:
create table foo
(
id integer generated always as identity
);
creates an identity column that can't be overridden unless explicitly asked for. The following insert will fail with a column defined as generated always
:
insert into foo (id)
values (1);
This can however be overruled:
insert into foo (id) overriding system value
values (1);
When using the option generated by default
this is essentially the same behaviour as the existing serial
implementation:
create table foo
(
id integer generated by default as identity
);
When a value is supplied manually, the underlying sequence needs to be adjusted manually as well - the same as with a serial
column.
An identity column is not a primary key by default (just like a serial
column). If it should be one, a primary key constraint needs to be defined manually.

Is there any efficient algorithm other than brute force search to find the three integers?
Yep; we can solve this in O(n2) time! First, consider that your problem P
can be phrased equivalently in a slightly different way that eliminates the need for a "target value":
original problem
P
: Given an arrayA
ofn
integers and a target valueS
, does there exist a 3-tuple fromA
that sums toS
?modified problem
P'
: Given an arrayA
ofn
integers, does there exist a 3-tuple fromA
that sums to zero?
Notice that you can go from this version of the problem P'
from P
by subtracting your S/3 from each element in A
, but now you don't need the target value anymore.
Clearly, if we simply test all possible 3-tuples, we'd solve the problem in O(n3) -- that's the brute-force baseline. Is it possible to do better? What if we pick the tuples in a somewhat smarter way?
First, we invest some time to sort the array, which costs us an initial penalty of O(n log n). Now we execute this algorithm:
for (i in 1..n-2) {
j = i+1 // Start right after i.
k = n // Start at the end of the array.
while (k >= j) {
// We got a match! All done.
if (A[i] + A[j] + A[k] == 0) return (A[i], A[j], A[k])
// We didn't match. Let's try to get a little closer:
// If the sum was too big, decrement k.
// If the sum was too small, increment j.
(A[i] + A[j] + A[k] > 0) ? k-- : j++
}
// When the while-loop finishes, j and k have passed each other and there's
// no more useful combinations that we can try with this i.
}
This algorithm works by placing three pointers, i
, j
, and k
at various points in the array. i
starts off at the beginning and slowly works its way to the end. k
points to the very last element. j
points to where i
has started at. We iteratively try to sum the elements at their respective indices, and each time one of the following happens:
j
closer to the end to select the next biggest number.k
closer to the beginning to select the next smallest number.For each i
, the pointers of j
and k
will gradually get closer to each other. Eventually they will pass each other, and at that point we don't need to try anything else for that i
, since we'd be summing the same elements, just in a different order. After that point, we try the next i
and repeat.
Eventually, we'll either exhaust the useful possibilities, or we'll find the solution. You can see that this is O(n2) since we execute the outer loop O(n) times and we execute the inner loop O(n) times. It's possible to do this sub-quadratically if you get really fancy, by representing each integer as a bit vector and performing a fast Fourier transform, but that's beyond the scope of this answer.
Note: Because this is an interview question, I've cheated a little bit here: this algorithm allows the selection of the same element multiple times. That is, (-1, -1, 2) would be a valid solution, as would (0, 0, 0). It also finds only the exact answers, not the closest answer, as the title mentions. As an exercise to the reader, I'll let you figure out how to make it work with distinct elements only (but it's a very simple change) and exact answers (which is also a simple change).
You need to use background-size: 100% 100%;
Demo 2 (Won't stretch, this is what you are doing)
Explanation: You need to use 100% 100%
as it sets for X
AS WELL AS Y
, you are setting 100%
just for the X
parameter, thus the background doesn't stretch vertically.
Still, the image will stretch out, it won't be responsive, if you want to stretch the background
proportionately, you can look for background-size: cover;
but IE will create trouble for you here as it's CSS3 property, but yes, you can use CSS3 Pie as a polyfill. Also, using cover
will crop your image.
finalName is created as:
<build>
<finalName>${project.artifactId}-${project.version}</finalName>

One of the solutions is to add own property:

</properties>
<build>
<finalName>${finalName}</finalName>
</build>
And now try:
mvn -DfinalName=build clean package
This is really old, but I wanted to add my slight variation for anyone else who may stumble across this. Regular expressions are powerful things.
To keep the text which falls between the equal sign and the comma:
-replace "^.*?=(.*?),.*?$",'$1'
This regular expression starts at the beginning of the line, wipes all characters until the first equal sign, captures every character until the next comma, then wipes every character until the end of the line. It then replaces the entire line with the capture group (anything within the parentheses). It will match any line that contains at least one equal sign followed by at least one comma. It is similar to the suggestion by Trix, but unlike that suggestion, this will not match lines which only contain either an equal sign or a comma, it must have both in order.
$python 2.7.8
from timeit import timeit
import numpy
timeit("list(0 for i in xrange(0, 100000))", number=1000)
> 8.173301935195923
timeit("[0 for i in xrange(0, 100000)]", number=1000)

timeit('list(itertools.repeat(0, 100000))', 'import itertools', number=1000)
> 1.0820629596710205
You should use [0] * n
to generate a list with n
zeros.
See why [] is faster than list()
There is a gotcha though, both itertools.repeat
and [0] * n
will create lists whose elements refer to same id
. This is not a problem with immutable objects like integers or strings but if you try to create list of mutable objects like a list of lists ([[]] * n
) then all the elements will refer to the same object.
a = [[]] * 10
a[0].append(1)
a
> [[1], [1], [1], [1], [1], [1], [1], [1], [1], [1]]
[0] * n
will create the list immediately while repeat
can be used to create the list lazily when it is first accessed.
If you're dealing with really large amount of data and your problem doesn't need variable length of list or multiple data types within the list it is better to use numpy
arrays.
timeit('numpy.zeros(100000, numpy.int)', 'import numpy', number=1000)
> 0.057849884033203125
numpy
arrays will also consume less memory.
For example, like this:
const querystring = require('querystring');
const https = require('https');
var postData = querystring.stringify({
'msg' : 'Hello World!'
});
var options = {
hostname: 'posttestserver.com',
port: 443,
path: '/post.php',
method: 'POST',
headers: {
'Content-Type': 'application/x-www-form-urlencoded',
'Content-Length': postData.length
}
};
var req = https.request(options, (res) => {
console.log('statusCode:', res.statusCode);
console.log('headers:', res.headers);
res.on('data', (d) => {
process.stdout.write(d);
});
});
req.on('error', (e) => {
console.error(e);
});
req.write(postData);
req.end();

New Operator for lambda expression added in java 8
Lambda expression is the short way of method writing.
It is indirectly used to implement functional interface

A simple answer to this question can be:
I Think It Will Help. I Used Simple Code Like:
#include <iostream>
using namespace std;
int main()
{int n,r;
cout<<"Enter Your Number:";
cin>>n;
while(n!=0)
{
r=n%10;
n=n/10;
cout<<r;
}
cout<<endl;
system("PAUSE");
return 0;
}
You can never instantiate an interface in java. You can, however, refer to an object that implements an interface by the type of the interface. For example,
public interface A
{
}
public class B implements A
{
}
public static void main(String[] args)
{
A test = new B();
//A test = new A(); // wont compile
}
What you did above was create an Anonymous class that implements the interface. You are creating an Anonymous object, not an object of type interface Test

Late to the party, but I was trying to get this done in TypeScript and came up with this:
<div onKeyPress={(e: KeyboardEvent<HTMLDivElement>) => console.log(e.key)}
This prints the exact key pressed to the screen. So if you want to respond to all "a" presses when the div is in focus, you'd compare e.key to "a" - literally if(e.key === "a").
If your whole JavaScript code gets processed by PHP, then you can do it just like that.
If you have individual .js
files, and you don't want PHP to process them (for example, for caching reasons), then you can just pass variables around in JavaScript.
For example, in your index.php
(or wherever you specify your layout), you'd do something like this:
<script type="text/javascript">
var my_var = <?php echo json_encode($my_var); ?>;
</script>
You could then use my_var
in your JavaScript files.
This method also lets you pass other than just simple integer values, as json_encode()
also deals with arrays, strings, etc. correctly, serialising them into a format that JavaScript can use.

I followed @Brad Parks answer. On Windows you should import rootCA.pem in Trusted Root Certificates Authorities store.
I did the following steps:
openssl genrsa -out rootCA.key 4096
openssl req -x509 -new -nodes -key rootCA.key -newkey rsa:4096 -sha256 -days 1024 -out rootCA.pem
openssl req -new -newkey rsa:4096 -sha256 -nodes -keyout device.key -out device.csr
openssl x509 -req -in device.csr -CA rootCA.pem -CAkey rootCA.key -CAcreateserial -out device.crt -days 2000 -sha256 -extfile v3.ext
Where v3.ext is:
authorityKeyIdentifier=keyid,issuer
basicConstraints=CA:FALSE
keyUsage = digitalSignature, nonRepudiation, keyEncipherment, dataEncipherment
subjectAltName = @alt_names

DNS.1 = localhost
IP.1 = 192.168.0.2
IP.2 = 127.0.0.1
Then, in my case I have a self hosted web app, so I need to bind certificate with IP address and port, certificate should be on MY store with private key information, so I exported to pfx format.
openssl pkcs12 -export -out device.pfx -inkey device.key -in device.crt
With mmc console (File/Add or Remove Snap-ins/Certificates/Add/Computert Account/LocalComputer/OK) I imported pfx file in Personal store.
Later I used this command to bind certificate (you could also use HttpConfig tool):
netsh http add sslcert ipport=0.0.0.0:12345 certhash=b02de34cfe609bf14efd5c2b9be72a6cb6d6fe54 appid={BAD76723-BF4D-497F-A8FE-F0E28D3052F4}
certhash=Certificate Thumprint
appid=GUID (your choice)
First I tried to import the certificate "device.crt" on Trusted Root Certificates Authorities in different ways but I'm still getting same error:
But I realized that I should import certificate of root authority not certificate for domain. So I used mmc console (File/Add or Remove Snap-ins/Certificates/Add/Computert Account/LocalComputer/OK) I imported rootCA.pem in Trusted Root Certificates Authorities store.

With makecert it is not possible add SAN information. With New-SelfSignedCertificate (Powershell) you could add SAN information, it also works.
Getting an ECONNREFUSED errno means that your kernel was refused a connection at the other end, so if it's a bug, it's either in your kernel or in the other end. What you can do is to trap the error in a very specific way and try again in a little while, since this seems to work:
# This is Python > 2.5 code
import errno, time
for attempt in range(MAXIMUM_NUMBER_OF_ATTEMPTS):
try:
# your urllib call here
except EnvironmentError as exc: # replace " as " with ", " for Python<2.6
if exc.errno == errno.ECONNREFUSED:
time.sleep(A_COUPLE_OF_SECONDS)
else:
raise # re-raise otherwise
else: # we tried, and we had no failure, so
break
else: # we never broke out of the for loop
raise RuntimeError("maximum number of unsuccessful attempts reached")
Replace the two all-caps constants with your favourite numbers.
My project use ButterKnife and Retro lambda, setting JavaVersion.VERSION_1_8 will not work. It always blames at ButterKnife static interface function until I found this Migrate from Retrolambda

An easy way to implement multiple field comparisons is with Guava's ComparisonChain - then you can say
public int compareTo(Foo that) {
return ComparisonChain.start()
.compare(lastName, that.lastName)
.compare(firstName, that.firstName)
.compare(zipCode, that.zipCode)
.result();
}
instead of
public int compareTo(Person other) {
int cmp = lastName.compareTo(other.lastName);
if (cmp != 0) {
return cmp;
}
cmp = firstName.compareTo(other.firstName);
if (cmp != 0) {
return cmp;
}
return Integer.compare(zipCode, other.zipCode);
}
}
Yes, it is a hash mapping or hash table. You can read a description of python's dict implementation, as written by Tim Peters, here.
That's why you can't use something 'not hashable' as a dict key, like a list:
>>> a = {}
>>> b = ['some', 'list']
>>> hash(b)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: list objects are unhashable
>>> a[b] = 'some'
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: list objects are unhashable
You can read more about hash tables or check how it has been implemented in python and why it is implemented that way.

You normally use a tool like pip
to install wheels. Leave it to the tool to discover and download the file if this is for a project hosted on PyPI.
For this to work, you do need to install the wheel
package:
pip install wheel
You can then tell pip
to install the project (and it'll download the wheel if available), or the wheel file directly:
pip install project_name # discover, download and install
pip install wheel_file.whl # directly install the wheel
The wheel
module, once installed, also is runnable from the command line, you can use this to install already-downloaded wheels:
python -m wheel install wheel_file.whl
Also see the wheel
project documentation.

Basic validation can be performed by choosing the type attribute of input elements. For example:
<input type="email" />
<input type="URL" />
<input type="number" />
using pattern attribute like:
<input type="text" pattern="[1-4]{5}" />
required attribute
<input type="text" required />
maxlength:
<input type="text" maxlength="20" />
min & max:
<input type="number" min="1" max="4" />
attr_accessor
is getter
, setter
method.
whereas attr_accessible
is to say that particular attribute is accessible or not. that's it.
I wish to add we should use Strong parameter instead of attr_accessible
to protect from mass asignment.
Cheers!
Looking at your output maybe the following query can work, give it a try:
SELECT * FROM tablename
WHERE id IN
(SELECT MIN(id) FROM tablename GROUP BY EmailAddress)
This will select only one row for each distinct email address, the row with the minimum id
which is what your result seems to portray
It works for me very nicely:
var x = '/Controller/Action?id=11112&value=4444';
var remove_after= x.indexOf('?');
var result = x.substring(0, remove_after);
alert(result);
Try echo $'a\nb'
.
If you want to store it in a variable and then use it with the newlines intact, you will have to quote your usage correctly:
var=$'a\nb\nc'
echo "$var"
Or, to fix your example program literally:
var="a b c"
for i in $var; do
p="`echo -e "$p\\n$i"`"
done
echo "$p"
function GetUserIP(){
var ret_ip;
$.ajaxSetup({async: false});
$.get('http://jsonip.com/', function(r){
ret_ip = r.ip;
});
return ret_ip;
}
If you want to use the IP and assign it to a variable, Try this. Just call GetUserIP()
You need to create new TextNodes as well as td nodes for each column, not reuse them among all of the columns as your code is doing.
Edit: Revise your code like so:
for (var i = 1; i < 4; i++)
{
tr[i] = document.createElement('tr');
var td1 = document.createElement('td');
var td2 = document.createElement('td');
td1.appendChild(document.createTextNode('Text1'));
td2.appendChild(document.createTextNode('Text2'));
tr[i].appendChild(td1);
tr[i].appendChild(td2);
table.appendChild(tr[i]);
}
Unless you want to go the VBA route to work out the Tab name, the Excel formula is fairly ugly based upon Mid functions, etc. But both these methods can be found here if you want to go that way.
Rather, the way I would do it is:
1) Make one cell on your sheet named, for example, Reference_Sheet
and put in that cell the value "Jan Item" for example.
2) Now, use the Indirect
function like:
=INDIRECT(Reference_Sheet&"!J3")
3) Now, for each month's sheet, you just have to change that one Reference_Sheet
cell.
Hope this gives you what you're looking for!

In C# 9 Microsoft will introduce a new way to have properties set only on initialization using the init;
method like so:
public class Person
{
public string firstName { get; init; }
public string lastName { get; init; }
}
This way, you can assign values when initializing a new object:
var person = new Person
{
firstname = "John",
lastName = "Doe"
}
But later on, you cannot change it:
person.lastName = "Denver"; // throws a compiler error
easiest way to append class name using javascript.
It can be useful when .siblings()
are misbehaving.
document.getElementById('myId').className += ' active';
The canonical T-SQL (SqlServer) answer is to use a DELETE
with JOIN
as such
DELETE o
FROM Orders o
INNER JOIN Customers c
ON o.CustomerId = c.CustomerId
WHERE c.FirstName = 'sklivvz'
This will delete all orders which have a customer with first name Sklivvz.
The easiest way only if you don't need return something it'ts just return null
If you don't want to type, you can create the statements with this:
USE Databasename
SELECT 'DROP TABLE [' + name + '];'
FROM sys.tables
Then copy and paste into a new SSMS window to run it.
Store it in multi valued column with a comma separator in an RDBMs table.
Describe the differences between the "four" (not three ;)) types of inner class..
Pipes are a way of streaming data between applications. Under Linux I use this all the time to stream the output of one process into another. This is anonymous because the destination app has no idea where that input-stream comes from. It doesn't need to.
A named pipe is just a way of actively hooking onto an existing pipe and hoovering-up its data. It's for situations where the provider doesn't know what clients will be eating the data.
This answers did not help me, my php adminer showed me "No input file specified" error anyway. But I knew I changed php-version before. So, I found the reason: it is not nginx, it is php.ini doc_root parameter! I found
doc_root =
in php.ini and changed it to
;doc_root =
After this patch my adminer work good.
To customize circular ProgressBar we need to create a indeterminateDrawable to show custom progress bar
<?xml version="1.0" encoding="utf-8"?>
<rotate xmlns:android="http://schemas.android.com/apk/res/android"
android:fromDegrees="0"
android:pivotX="50%"
android:pivotY="50%"
android:duration="1">
<shape
android:innerRadiusRatio="3"
android:shape="ring"
android:thicknessRatio="8"
android:useLevel="false">
<size
android:height="48dip"
android:width="48dip" />
<gradient
android:centerColor="#f96047"
android:centerY="0.50"
android:endColor="#fb9c8d"
android:startColor="#f72d0c"
android:type="sweep"
android:useLevel="false" />
</shape>
</rotate>
We need to include drawable in progressbar just as below:
<ProgressBar
android:layout_width="wrap_content"
android:layout_centerInParent="true"
style="?android:attr/progressBarStyleLarge"
android:visibility="visible"
android:progressDrawable="@drawable/widget_progressbar"
android:indeterminateDrawable="@drawable/widget_progressbar"
android:layout_height="wrap_content" />
Just use this:
$(function() {
$('#watchButton').trigger('click');
});
As you can see many answers above, But i would like to post a quick solution which works for sure in Anaconda3. I haven't chosen Visual Studio as it consumes lot of memory.
Please follow the below steps.
Step 1:
Install windows cmake.msi and configure environment variable
Step 2:
Create a conda environment, and install cmake using the below command.
pip install cmake
Step 3:
conda install -c conda-forge dlib
Note you can find few other dlib packages, but the above one will works perfectly with this procedure.
dlib will be successfully installed.
In Linux try
pkill nodejs
//or
pkill node
css is enough :
width : desired_width;
height: auto;/*to preserve the aspect ratio of the image*/
It is something concerned with the graphics drivers. If you update them you will be fine.
Or you can disable the hardware graphics acceleration in Visual Studio according to these steps:
In Visual Studio, click "Tools", and then click "Options".
In the Options dialog box, navigate to the "Environment > General" section and clear the "Automatically adjust visual experience based on client performance" check box. (Refer to the following screen shot for this step.)
Clear the "Use hardware graphics acceleration if available" check box to prevent the use of hardware graphics acceleration.
Select or clear the "Enable rich client visual experience" check box to make sure that rich visuals are always on or off, respectively. When this check box is selected, rich visuals are used independent of the computer environment. For example, rich visuals are used when you run Visual Studio locally on a rich client and over remote desktop.

I got a better method from here: WCF: Creating Custom Headers, How To Add and Consume Those Headers
Client Identifies Itself
The goal here is to have the client provide some sort of information which the server can use to determine who is sending the message. The following C# code will add a header named ClientId:
var cl = new ActiveDirectoryClient();
var eab = new EndpointAddressBuilder(cl.Endpoint.Address);
eab.Headers.Add( AddressHeader.CreateAddressHeader("ClientId", // Header Name
string.Empty, // Namespace
"OmegaClient")); // Header Value
cl.Endpoint.Address = eab.ToEndpointAddress();
// Now do an operation provided by the service.
cl.ProcessInfo("ABC");
What that code is doing is adding an endpoint header named ClientId with a value of OmegaClient to be inserted into the soap header without a namespace.
Custom Header in Client’s Config File
There is an alternate way of doing a custom header. That can be achieved in the Xml config file of the client where all messages sent by specifying the custom header as part of the endpoint as so:
<configuration>
<startup>
<supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5" />
</startup>
<system.serviceModel>
<bindings>
<basicHttpBinding>
<binding name="BasicHttpBinding_IActiveDirectory" />
</basicHttpBinding>
</bindings>
<client>
<endpoint address="http://localhost:41863/ActiveDirectoryService.svc"
binding="basicHttpBinding" bindingConfiguration="BasicHttpBinding_IActiveDirectory"
contract="ADService.IActiveDirectory" name="BasicHttpBinding_IActiveDirectory">
<headers>
<ClientId>Console_Client</ClientId>
</headers>
</endpoint>
</client>
</system.serviceModel>
</configuration>
In our code we have a specific validator inherited from the BaseValidator class.
This class does the following:
This is the closest you can get to validation without actually sending the person an e-mail confirmation link.
One option seems to be using CSS to style the textarea
.multi-line { height:5em; width:5em; }
See this entry on SO or this one.
Amurra's accepted answer seems to imply this class is added automatically when using EditorFor but you'd have to verify this.
EDIT: Confirmed, it does. So yes, if you want to use EditorFor, using this CSS style does what you're looking for.
<textarea class="text-box multi-line" id="StoreSearchCriteria_Location" name="StoreSearchCriteria.Location">
Here's how I solved it, with nullable double extension method.
public static bool NearlyEquals(this double? value1, double? value2, double unimportantDifference = 0.0001)
{
if (value1 != value2)
{
if(value1 == null || value2 == null)
return false;
return Math.Abs(value1.Value - value2.Value) < unimportantDifference;
}
return true;
}
...
double? value1 = 100;
value1.NearlyEquals(100.01); // will return false
value1.NearlyEquals(100.000001); // will return true
value1.NearlyEquals(100.01, 0.1); // will return true
You will want to use the a ternary operator which acts as a shortened IF/Else statement:
echo '<option value="'.$value.'" '.(($value=='United States')?'selected="selected"':"").'>'.$value.'</option>';
I use the latest version of SSMS or sql server management studio. I have a SQL script (in query editor) which has about 100 lines of code. This is error I got in the query:
Msg 245, Level 16, State 1, Line 2
Conversion failed when converting the nvarchar value 'abcd' to data type int.
Solution - I had seen this kind of error before when I forgot to enclose a number (in varchar column) in single quotes.
As an aside, the error message is misleading. The actual error on line number 70 in the query editor and not line 2 as the error says!
This little example shows how the $rootScope
emit a event that will be listen by a children scope in another controller.
(function(){
angular
.module('ExampleApp',[]);
angular
.module('ExampleApp')
.controller('ExampleController1', Controller1);
Controller1.$inject = ['$rootScope'];
function Controller1($rootScope) {
var vm = this,
message = 'Hi my children scope boy';
vm.sayHi = sayHi;
function sayHi(){
$rootScope.$broadcast('greeting', message);
}
}
angular
.module('ExampleApp')
.controller('ExampleController2', Controller2);
Controller2.$inject = ['$scope'];
function Controller2($scope) {
var vm = this;
$scope.$on('greeting', listenGreeting)
function listenGreeting($event, message){
alert(['Message received',message].join(' : '));
}
}
})();

The answer of @gayathri bottom explain technically the differences of all those methods in the scope angular concept and their implementations $scope
and $rootScope
.
In some situations you can hide the shadow by another container. Eg, if there is a DIV above and below the DIV with the shadow, you can use position: relative; z-index: 1;
on the surrounding DIVs.
The reason is that your are defining your imageSegment
outside of a function in your source code (static variable).
In such cases, the initialization cannot include execution of code, like calling a function or allocation a class. Initializer must be a constant whose value is known at compile time.
You can then initialize your static variable inside of your init
method (if you postpone its declaration to init).
As a few people have mentioned, the parameters in paramMap
should be accessed using the common Map
API:
To get a snapshot of the params, when you don't care that they may change:
this.bankName = this.route.snapshot.paramMap.get('bank');
To subscribe and be alerted to changes in the parameter values (typically as a result of the router's navigation)
this.route.paramMap.subscribe( paramMap => {
this.bankName = paramMap.get('bank');
})
Since Angular 4, params
have been deprecated in favor of the new interface paramMap
. The code for the problem above should work if you simply substitute one for the other.
If you inject ActivatedRoute
in your component, you'll be able to extract the route parameters
import {ActivatedRoute} from '@angular/router';
...
constructor(private route:ActivatedRoute){}
bankName:string;
ngOnInit(){
// 'bank' is the name of the route parameter
this.bankName = this.route.snapshot.params['bank'];
}
If you expect users to navigate from bank to bank directly, without navigating to another component first, you ought to access the parameter through an observable:
ngOnInit(){
this.route.params.subscribe( params =>
this.bankName = params['bank'];
)
}
For the docs, including the differences between the two check out this link and search for "activatedroute"
Use the vbcrlf
for new line in SSSR. e.g.
= First(Fields!SAPName.Value, "DataSet1") & vbcrlf & First(Fields!SAPStreet.Value, "DataSet1") & vbcrlf & First(Fields!SAPCityPostal.Value, "DataSet1") & vbcrlf & First(Fields!SAPCountry.Value, "DataSet1")
var color = Enum.Parse<Colors>("Green");
Both facet_wrap
and facet_grid
also accept input from ifelse
as an argument. So if the variable used for faceting is logical, the solution is very simple:
facet_wrap(~ifelse(variable, "Label if true", "Label if false"))
If the variable has more categories, the ifelse
statement needs to be nested.
As a side effect, this also allows the creation of the groups to be faceted within the ggplot
call.
If we can determine and aggregate all the attributes and values together before creating the nested object, then we could create a new class that takes a dictionary argument on creation.
# python 2.7
class NestedObject():
def __init__(self, initial_attrs):
for key in initial_attrs:
setattr(self, key, initial_attrs[key])
obj = someobject
attributes = { 'attr1': 'val1', 'attr2': 'val2', 'attr3': 'val3' }
obj.a = NestedObject(attributes)
>>> obj.a.attr1
'val1'
>>> obj.a.attr2
'val2'
>>> obj.a.attr3
'val3'
We can also allow keyword arguments. See this post.
class NestedObject(object):
def __init__(self, *initial_attrs, **kwargs):
for dictionary in initial_attrs:
for key in dictionary:
setattr(self, key, dictionary[key])
for key in kwargs:
setattr(self, key, kwargs[key])
obj.a = NestedObject(attr1='val1', attr2='val2', attr3= 'val3')

function yourFunction($var1, $var2, $optional = Null){

You can make a regular function and then add your optional variables by giving them a default Null value.
A Null is still a value, if you don't call the function with a value for that variable, it won't be empty so no error.

I solve this problem in MvcMusicStore by add this part of code in _Layout.cshtml
@if (IsSectionDefined("scripts"))
{
@RenderSection("scripts", required: false)

and remove this code from Edit.cshtml
@section Scripts {
@Scripts.Render("~/bundles/jqueryval")
}
Run the program inshallah will work with you.
An update to the correct answer phil provided, for more recent versions of Pycharm (e.g. 2019.2).
Go to File > Settings and find your project, then select Project Interpreter. Now click the button with a cog to the right of the selected project interpreter (used to be a ...).
From the drop-down menu select Show All... and in the dialog that opens click the icon with a folder and two sub-folders.
You are presented with a dialog with the current interpreter paths, click on + to add one more.
Type "set" and you will get a list of all the current variables. If you want something to persist put it in ~/.bashrc or ~/.bash_profile (if you're using bash)
convert Collection into string as comma seperated in Java 8
listOfString object contains ["A","B","C" ,"D"] elements-
listOfString.stream().map(ele->"'"+ele+"'").collect(Collectors.joining(","))
Output is :- 'A','B','C','D'
And Convert Strings Array to List in Java 8
String string[] ={"A","B","C","D"};
List<String> listOfString = Stream.of(string).collect(Collectors.toList());
Edit: Seems the OP is running a long script, in that case one only needs to wrap the part of the script after the quality control with
if (n >= 500) {
.... long running code here
}
If breaking out of a function, you'll probably just want return()
, either explicitly or implicitly.
For example, an explicit double return
foo <- function(x) {
if(x < 10) {
return(NA)
} else {
xx <- seq_len(x)
xx <- cumsum(xx)
}
xx ## return(xx) is implied here
}
> foo(5)
[1] 0
> foo(10)
[1] 1 3 6 10 15 21 28 36 45 55
By return()
being implied, I mean that the last line is as if you'd done return(xx)
, but it is slightly more efficient to leave off the call to return()
.
Some consider using multiple returns bad style; in long functions, keeping track of where the function exits can become difficult or error prone. Hence an alternative is to have a single return point, but change the return object using the if () else ()
clause. Such a modification to foo()
would be
foo <- function(x) {
## out is NA or cumsum(xx) depending on x
out <- if(x < 10) {
NA
} else {
xx <- seq_len(x)
cumsum(xx)
}
out ## return(out) is implied here
}
> foo(5)
[1] NA
> foo(10)
[1] 1 3 6 10 15 21 28 36 45 55
Moreover, to convert whatever you want, you can use the QVariant class.
for example:
std::string str("hello !");
qDebug() << QVariant(str.c_str()).toString();
int test = 10;
double titi = 5.42;
qDebug() << QVariant(test).toString();
qDebug() << QVariant(titi).toString();
qDebug() << QVariant(titi).toInt();
output
"hello !"
"10"
"5.42"
5
