You need to check the accelerometer via accelerometer:didAccelerate: method which is part of the UIAccelerometerDelegate protocol and check whether the values go over a threshold for the amount of movement needed for a shake.
There is decent sample code in the accelerometer:didAccelerate: method right at the bottom of AppController.m in the GLPaint example which is available on the iPhone developer site.
I can't comment on @omega's comment because I don't have enough reputation but the answer to that question should be something like:
shake.xml
<?xml version="1.0" encoding="utf-8"?>
<rotate xmlns:android="http://schemas.android.com/apk/res/android"
android:duration="100" <!-- how long the animation lasts -->
android:fromDegrees="-5" <!-- how far to swing left -->
android:pivotX="50%" <!-- pivot from horizontal center -->
android:pivotY="50%" <!-- pivot from vertical center -->
android:repeatCount="10" <!-- how many times to swing back and forth -->
android:repeatMode="reverse" <!-- to make the animation go the other way -->
android:toDegrees="5" /> <!-- how far to swing right -->
Class.java
Animation shake = AnimationUtils.loadAnimation(this, R.anim.shake);
view.startAnimation(shake);
This is just one way of doing what you want, there may be better methods out there.

You cannot use ++
on something which is not a variable, this would be the closest you can get:
$('#counter').html(function(i, val) { return +val+1 });
jQuery's html()
method can get and set the HTML value of an element. If passed a function it can update the HTML based upon the existing value. So in the context of your code:
$("#update").click(function() {
$('#counter').html(function(i, val) { return +val+1 });
}
DEMO: http://jsfiddle.net/marcuswhybrow/zRX2D/2/
When it comes to synchronising your counter on the page, with the counter value in your database, never trust the client! You send either an increment or decrement signal to you server side script, rather than a continuous value such as 10, or 23.
However you could send an AJAX request to the server when you change the HTML of your counter:
$("#update").click(function() {
$('#counter').html(function(i, val) {
$.ajax({
url: '/path/to/script/',
type: 'POST',
data: {increment: true},
success: function() { alert('Request has returned') }
});
return +val+1;
});
}
This answer predates version 1.1.5 where a proper ternary in the $parse
function wasn't available. Use this answer if you're on a lower version, or as an example of filters:
angular.module('myApp.filters', [])
.filter('conditional', function() {
return function(condition, ifTrue, ifFalse) {
return condition ? ifTrue : ifFalse;
};
});
And then use it as
<i ng-class="checked | conditional:'icon-check':'icon-check-empty'"></i>
This is because of a huge view state, In my case I got lucky since I was not using the viewstate. I just added enableviewstate="false"
on the form tag and view state went from 35k to 100 chars
-w
is the GCC-wide option to disable warning messages.
You can use:
getActiveNetworkInfo();
ConnectivityManager cm = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo activeNetwork = cm.getActiveNetworkInfo();
if (activeNetwork != null) {
// connected to the internet
if (activeNetwork.getType() == ConnectivityManager.TYPE_WIFI) {
// connected to wifi
} else if (activeNetwork.getType() == ConnectivityManager.TYPE_MOBILE) {
// connected to mobile data
}
} else {
// not connected to the internet
}
Or in a switch case
ConnectivityManager cm = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo activeNetwork = cm.getActiveNetworkInfo();
if (activeNetwork != null) {
// connected to the internet
switch (activeNetwork.getType()) {
case ConnectivityManager.TYPE_WIFI:
// connected to wifi
break;
case ConnectivityManager.TYPE_MOBILE:
// connected to mobile data
break;
default:
break;
}
} else {
// not connected to the internet
}
I use this, it's great, but I have 2 problems with the template:
And for TimeField I have 'Enter a valid date.'
models.py
from django.db import models
name=models.CharField(max_length=100)
create_date=models.DateField(blank=True)
start_time=models.TimeField(blank=False)
end_time=models.TimeField(blank=False)
forms.py
from django import forms
from .models import Guide
from django.contrib.admin import widgets
class GuideForm(forms.ModelForm):
start_time = forms.DateField(widget=widgets.AdminTimeWidget)
end_time = forms.DateField(widget=widgets.AdminTimeWidget)
create_date = forms.DateField(widget=widgets.AdminDateWidget)
class Meta:
model=Guide
fields=['name','categorie','thumb']
Fast:
SELECT TOP (1) CASE
WHEN **NOT_NULL_COLUMN** IS NULL
THEN 'empty table'
ELSE 'not empty table'
END AS info
FROM **TABLE_NAME**
You can increment the stack depth allowed - with this, deeper recursive calls will be possible, like this:
import sys
sys.setrecursionlimit(10000) # 10000 is an example, try with different values
... But I'd advise you to first try to optimize your code, for instance, using iteration instead of recursion.
The easy way to fix this is to add this to your form.
{{ csrf_field() }}
<input type="hidden" name="_method" value="PUT">
then the update method will be like this :
public function update(Request $request, $id)
{
$project = Project::findOrFail($id);
$project->name = $request->name;
$project->description = $request->description;
$post->save();
}
You can also put your templates folder under src/main/resources instead of src/main/java. Works for me and it's a preferable location since templates are not java source.

To close the current cmd windows immediately, just add as the last command/line:
move nul 2>&0
Try move nul
to nowhere and redirect the stderr to stdin
will result in the current window cmd.exe being closed
This is different from closing a bat, or exiting it using goto :EOF

SQL has an error raising mechanism
RAISERROR ( { msg_id | msg_str | @local_variable }
{ ,severity ,state }
[ ,argument [ ,...n ] ] )
[ WITH option [ ,...n ] ]
Just look up Raiserror in the Books Online. But.. you have to generate an error of the appropriate severity, an error at severity 0 thru 10 do not cause you to jump to the catch block.
I always used a couple lines of code which clear the input stream of any characters and then wait for input to ignore.
Something like:
void pause() {
cin.clear();
cout << endl << "Press any key to continue...";
cin.ignore();
}
And then any time I need it in the program I have my own pause(); function, without the overhead of a system pause. This is only really an issue when writing console programs that you want to stay open or stay fixated on a certain point though.
Swift 5 solution
cell.imageView?.image = UIImage.init(named: "yourImageName")
As it has been pointed out, it depends on the type. For built-in data types, it is best to pass by value. Even some very small structures, such as a pair of ints can perform better by passing by value.
Here is an example, assume you have an integer value and you want pass it to another routine. If that value has been optimized to be stored in a register, then if you want to pass it be reference, it first must be stored in memory and then a pointer to that memory placed on the stack to perform the call. If it was being passed by value, all that is required is the register pushed onto the stack. (The details are a bit more complicated than that given different calling systems and CPUs).
If you are doing template programming, you are usually forced to always pass by const ref since you don't know the types being passed in. Passing penalties for passing something bad by value are much worse than the penalties of passing a built-in type by const ref.
Along the same lines as previous answers, but a very short addition that Allows to use all Control properties without having cross thread invokation exception.
Helper Method
/// <summary>
/// Helper method to determin if invoke required, if so will rerun method on correct thread.
/// if not do nothing.
/// </summary>
/// <param name="c">Control that might require invoking</param>
/// <param name="a">action to preform on control thread if so.</param>
/// <returns>true if invoke required</returns>
public bool ControlInvokeRequired(Control c,Action a)
{
if (c.InvokeRequired) c.Invoke(new MethodInvoker(delegate { a(); }));
else return false;
return true;
}
Sample Usage
// usage on textbox
public void UpdateTextBox1(String text)
{
//Check if invoke requied if so return - as i will be recalled in correct thread
if (ControlInvokeRequired(textBox1, () => UpdateTextBox1(text))) return;
textBox1.Text = ellapsed;
}
//Or any control
public void UpdateControl(Color c,String s)
{
//Check if invoke requied if so return - as i will be recalled in correct thread
if (ControlInvokeRequired(myControl, () => UpdateControl(c,s))) return;
myControl.Text = s;
myControl.BackColor = c;
}
The easiest way is to include the gem 'activesupport'
(or gem 'active_support'
).
Then, in your class you only need to
require 'active_support/core_ext/hash/slice'
and to call
params.slice(:choice1, :choice2, :choice3) # => {:choice1=>"Oh look, another one", :choice2=>"Even more strings", :choice3=>"But wait"}
I believe it's not worth it to be declaring other functions that may have bugs, and it's better to use a method that has been tweaked during last few years.
For more recent settings, see Eclipse Galileo 3.5 settings above.
The best JVM setting always, in my opinion, includes the latest JDK you can find (so for now, jdk1.6.0_b07 up to b16, except b14 and b15)
Even with those pretty low memory settings, I can run large java projects (along with a web server) on my old (2002) desktop with 2Go RAM.

sudo
command not found
to check whether the sudo package is installed on your system, type sudo
, and press Enter . If you have sudo
installed the system will display a short help message, otherwise you will see something like sudo: command not found
To install sudo, run one of the following commands using root account:
apt-get install sudo
# If your system based on apt package manager
yum install sudo
# If your system based on yum package manager

Simple to do it in XAML, and surprised that nobody posted this answer yet. In the following example, the Window
is defined in a ResourceLibrary
(notice the x:Key
), but you can also use this XAML binding on a standalone Page
-style WPF resource.
<Window x:Key="other_window"
Topmost="{Binding Source={x:Static Application.Current},Path=MainWindow.IsActive,Mode=OneWay}">
<TextBlock Text="OTHER WINDOW" />
</Window>
I had a similar issue, but in my case it was because storage has only SFTP, without ssh or rsync daemons on it. I could not change anything, bcs this server was provided by my customer.
rsync could not change the date and time for the file, some other utilites (like csync) showed me other errors: "Unable to create temporary file Clock skew detected". If you have access to the storage-server - just install openssh-server or launch rsync as a daemon here.
In my case - I could not do this and solution was: lftp. lftp's usage for syncronization is below:
lftp -c "open -u login,password sftp://sft.domain.tld/; mirror -c --verbose=9 -e -R -L /srs/folder /rem/folder"
/src/folder - is the folder on my PC, /rem/folder - is sftp://sft.domain.tld/rem/folder.

It appears that tkFileDialog.askdirectory
should work. documentation
The command line for that is:
node -v
Or
node --version
Note:
If node -v
doesn't work, but nodejs -v
does, then something's not set up quite right on your system. See this other question for ways to fix it.
There's no direct function for this, but you can do it with a replace:
declare @myvar varchar(20)
set @myvar = 'Hello World'
select len(@myvar) - len(replace(@myvar,'o',''))
Basically this tells you how many chars were removed, and therefore how many instances of it there were.
Extra:
The above can be extended to count the occurences of a multi-char string by dividing by the length of the string being searched for. For example:
declare @myvar varchar(max), @tocount varchar(20)
set @myvar = 'Hello World, Hello World'
set @tocount = 'lo'
select (len(@myvar) - len(replace(@myvar,@tocount,''))) / LEN(@tocount)
constexpr indicates a value that's constant and known during compilation.
const indicates a value that's only constant; it's not compulsory to know during compilation.
int sz;
constexpr auto arraySize1 = sz; // error! sz's value unknown at compilation
std::array<int, sz> data1; // error! same problem
constexpr auto arraySize2 = 10; // fine, 10 is a compile-time constant
std::array<int, arraySize2> data2; // fine, arraySize2 is constexpr
Note that const doesn’t offer the same guarantee as constexpr, because const objects need not be initialized with values known during compilation.
int sz;
const auto arraySize = sz; // fine, arraySize is const copy of sz
std::array<int, arraySize> data; // error! arraySize's value unknown at compilation
All constexpr objects are const, but not all const objects are constexpr.
If you want compilers to guarantee that a variable has a value that can be used in contexts requiring compile-time constants, the tool to reach for is constexpr, not const.
I use requests for this, then it is easy and clean. Instead of print function you can define and call new function (notify via email etc.). Try-except block is essential, because if host is unreachable then it will rise a lot of exceptions so you need to catch them all.
import requests
URL = "https://api.github.com"
try:
response = requests.head(URL)
except Exception as e:
print(f"NOT OK: {str(e)}")
else:
if response.status_code == 200:
print("OK")
else:
print(f"NOT OK: HTTP response code {response.status_code}")
You can use CollationKey
objects instead of strings:
Locale locale = ...;
Collator collator = Collator.getInstance(locale);
collator.setStrength(Collator.SECONDARY); // Case-insensitive.
collator.setDecomposition(Collator.FULL_DECOMPOSITION);
CollationKey collationKey = collator.getCollationKey(stringKey);
hashMap.put(collationKey, value);
hashMap.get(collationKey);
Use Collator.PRIMARY
to ignore accent differences.
The CollationKey
API does not guarantee that hashCode()
and equals()
are implemented, but in practice you'll be using RuleBasedCollationKey
, which does implement these. If you're paranoid, you can use a TreeMap
instead, which is guaranteed to work at the cost of O(log n) time instead of O(1).
if, for any reasons, you don't want to add a wrapper (in my first case it was for <tr/>
components), you can use a functionnal component.
Instead of having a single components/MyCompo.vue
you will have few files in a components/MyCompo
folder :
components/MyCompo/index.js
components/MyCompo/File.vue
components/MyCompo/Avatar.vue
With this structure, the way you call your component won't change.
components/MyCompo/index.js
file content :
import File from './File';
import Avatar from './Avatar';
const commonSort=(a,b)=>b-a;
export default {
functional: true,
name: 'MyCompo',
props: [ 'someProp', 'plopProp' ],
render(createElement, context) {
return [
createElement( File, { props: Object.assign({light: true, sort: commonSort},context.props) } ),
createElement( Avatar, { props: Object.assign({light: false, sort: commonSort},context.props) } )
];
}
};
And if you have some function or data used in both templates, passed them as properties and that's it !
I let you imagine building list of components and so much features with this pattern.
There is one caveat here. In Firefox, if you reset the input text on every keyup, if the text is longer than the viewable area allowed by the input width, then resetting the value on every keyup breaks the browser functionality that auto scrolls the text to the caret position at the end of the text. Instead the text scrolls back to the beginning leaving the caret out of view.
function scroll(elementToBeScrolled)
{
//this will reset the scroll to the bottom of the viewable area.
elementToBeScrolled.topscroll = elementToBeScrolled.scrollheight;
}
use it:
.CopyToDataTable()
example:
string _sqlWhere = "Nachname = 'test'";
string _sqlOrder = "Nachname DESC";
DataTable _newDataTable = yurDateTable.Select(_sqlWhere, _sqlOrder).CopyToDataTable();

--vm C:\Program Files\Java\jdk1.7.0_01\jre\bin\javaw.exe
2. You need to give the exact java installed version:
--Dosgi.requiredJavaVersion=1.7
3. Try to reduce the memory size:
--XX:MaxPermSize=256m
The character set is part of the locale, which is determined by the value of NLS_LANG
. As the documentation makes clear this is an operating system variable:
NLS_LANG
is set as an environment variable on UNIX platforms.NLS_LANG
is set in the registry on Windows platforms.
Now we can use ALTER SESSION
to change the values for a couple of locale elements, NLS_LANGUAGE and NLS_TERRITORY. But not, alas, the character set. The reason for this discrepancy is - I think - that the language and territory simply effect how Oracle interprets the stored data, e.g. whether to display a comma or a period when displaying a large number. Wheareas the character set is concerned with how the client application renders the displayed data. This information is picked up by the client application at startup time, and cannot be changed from within.
Sorry I know this is an old one but still felt like helping out ^_^
Maybe it's the way I read this but assuming the excel sheet 1 is called "London" and has this information; B5="Marleybone" B6="Paddington" B7="Victoria" B8="Hammersmith". And the excel sheet 2 is called "Nottingham" and has this information; C5="Alverton" C6="Annesley" C7="Arnold" C8="Askham". Then I think this code below would work. ^_^
$xlCellTypeLastCell = 11
$startRow = 5
$excel = new-object -com excel.application
$wb = $excel.workbooks.open("C:\users\administrator\my_test.xls")
for ($i = 1; $i -le $wb.sheets.count; $i++)
{
$sh = $wb.Sheets.Item($i)
$endRow = $sh.UsedRange.SpecialCells($xlCellTypeLastCell).Row
$col = $col + $i - 1
$city = $wb.Sheets.Item($i).name
$rangeAddress = $sh.Cells.Item($startRow, $col).Address() + ":" + $sh.Cells.Item($endRow, $col).Address()
$sh.Range($rangeAddress).Value2 | foreach{
New-Object PSObject -Property @{City = $city; Area=$_}
}
}
$excel.Workbooks.Close()
This should be the output (without the commas):
City, Area
---- ----
London, Marleybone
London, Paddington
London, Victoria
London, Hammersmith
Nottingham, Alverton
Nottingham, Annesley
Nottingham, Arnold
Nottingham, Askham
Range("A1").value = Environ("Username")
This is better than Application.Username
, which doesn't always supply the Windows username. Thanks to Kyle for pointing this out.
Application Username
is the name of the User set in Excel > Tools > Options Environ("Username")
is the name you registered for Windows; see Control Panel >SystemAs @markE mention in his answer
the alternative is to untranslate & unrotate after drawing
It is much faster than context save and restore.
Here is an example
// translate and rotate
this.context.translate(x,y);
this.context.rotate(radians);
this.context.translate(-x,-y);
this.context.drawImage(...);
// untranslate and unrotate
this.context.translate(x, y);
this.context.rotate(-radians);
this.context.translate(-x,-y);
I had to use the install
function instead:
conda install pandas=0.13.1
How would you check if a variable is a dictionary in Python?
This is an excellent question, but it is unfortunate that the most upvoted answer leads with a poor recommendation, type(obj) is dict
.
(Note that you should also not use dict
as a variable name - it's the name of the builtin object.)
If you are writing code that will be imported and used by others, do not presume that they will use the dict builtin directly - making that presumption makes your code more inflexible and in this case, create easily hidden bugs that would not error the program out.
I strongly suggest, for the purposes of correctness, maintainability, and flexibility for future users, never having less flexible, unidiomatic expressions in your code when there are more flexible, idiomatic expressions.
is
is a test for object identity. It does not support inheritance, it does not support any abstraction, and it does not support the interface.
So I will provide several options that do.
This is the first recommendation I would make, because it allows for users to supply their own subclass of dict, or a OrderedDict
, defaultdict
, or Counter
from the collections module:
if isinstance(any_object, dict):
But there are even more flexible options.
from collections.abc import Mapping
if isinstance(any_object, Mapping):
This allows the user of your code to use their own custom implementation of an abstract Mapping, which also includes any subclass of dict
, and still get the correct behavior.
You commonly hear the OOP advice, "program to an interface".
This strategy takes advantage of Python's polymorphism or duck-typing.
So just attempt to access the interface, catching the specific expected errors (AttributeError
in case there is no .items
and TypeError
in case items
is not callable) with a reasonable fallback - and now any class that implements that interface will give you its items (note .iteritems()
is gone in Python 3):
try:
items = any_object.items()
except (AttributeError, TypeError):
non_items_behavior(any_object)
else: # no exception raised
for item in items: ...
Perhaps you might think using duck-typing like this goes too far in allowing for too many false positives, and it may be, depending on your objectives for this code.
Don't use is
to check types for standard control flow. Use isinstance
, consider abstractions like Mapping
or MutableMapping
, and consider avoiding type-checking altogether, using the interface directly.
I think the only way is by using internel PHP code like MANOJ and Fernando suggest.
curl post/get in php file on your server --> call this php file with ajax
The PHP file let say (fb.php):
$commentdata=$_GET['commentdata'];
$fbUrl="https://graph.facebook.com/16453004404_481759124404/comments?access_token=my_token";
curl_setopt($ch, CURLOPT_URL,$fbUrl);
curl_setopt($ch, CURLOPT_POST, 1);
// POST data here
curl_setopt($ch, CURLOPT_POSTFIELDS,
"message=".$commentdata);
// receive server response ...
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$server_output = curl_exec ($ch);
echo $server_output;
curl_close ($ch);
Than use AJAX GET to
fb.php?commentmeta=your comment goes here
from your server.
Or do this with simple HTML and JavaScript from externel server:
Message: <input type="text" id="message">
<input type="submit" onclick='PostMessage()'>
<script>
function PostMessage() {
var comment = document.getElementById('message').value;
window.location.assign('http://yourdomain.tld/fb.php?commentmeta='+comment)
}
</script>
I had these SQL behavior settings enabled on options query execution: ANSI SET IMPLICIT_TRANSACTIONS checked. On execution of your query e.g create, alter table or stored procedure, you have to COMMIT it.
Just type COMMIT and execute it F5
It's too simple. The var_dump() function displays structured information about variables/expressions including its type and value. Whereas The print_r() displays information about a variable in a way that's readable by humans.
Example: Say we have got the following array and we want to display its contents.
$arr = array ('xyz', false, true, 99, array('50'));
Array
(
[0] => xyz
[1] =>
[2] => 1
[3] => 99
[4] => Array
(
[0] => 50
)
)
array(5) {
[0]=>
string(3) "xyz"
[1]=>
bool(false)
[2]=>
bool(true)
[3]=>
int(100)
[4]=>
array(1) {
[0]=>
string(2) "50"
}
}

I used this code to show the dialog at the bottom of the screen:
Dialog dlg = <code to create custom dialog>;
Window window = dlg.getWindow();
WindowManager.LayoutParams wlp = window.getAttributes();
wlp.gravity = Gravity.BOTTOM;
wlp.flags &= ~WindowManager.LayoutParams.FLAG_DIM_BEHIND;
window.setAttributes(wlp);
This code also prevents android from dimming the background of the dialog, if you need it. You should be able to change the gravity parameter to move the dialog about
private void showPictureialog() {
final Dialog dialog = new Dialog(this,
android.R.style.Theme_Translucent_NoTitleBar);
// Setting dialogview
Window window = dialog.getWindow();
window.setGravity(Gravity.CENTER);
window.setLayout(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT);
dialog.setTitle(null);
dialog.setContentView(R.layout.selectpic_dialog);
dialog.setCancelable(true);
dialog.show();
}
you can customize you dialog based on gravity and layout parameters change gravity and layout parameter on the basis of your requirenment

Don't use wait()
, use either android.os.SystemClock.sleep(1000);
or Thread.sleep(1000);
.
The main difference between them is that Thread.sleep()
can be interrupted early -- you'll be told, but it's still not the full second. The android.os
call will not wake early.
It looks like your MySql session has the safe-updates option set. This means that you can't update or delete records without specifying a key (ex. primary key
) in the where clause.
Try:
SET SQL_SAFE_UPDATES = 0;
Or you can modify your query to follow the rule (use primary key
in where clause
).
You can do this with the ImageMagick extension. I'm guessing that the combineImages() method will do what you want.
The unfortunate truth about AJAX and the 302 redirect is that you can't get the headers from the return because the browser never gives them to the XHR. When a browser sees a 302 it automatically applies the redirect. In this case, you would see the header in firebug because the browser got it, but you would not see it in ajax, because the browser did not pass it. This is why the success and the error handlers never get called. Only the complete handler is called.
http://www.checkupdown.com/status/E302.html
The 302 response from the Web server should always include an alternative URL to which redirection should occur. If it does, a Web browser will immediately retry the alternative URL. So you never actually see a 302 error in a Web browser
Here are some stackoverflow posts on the subject. Some of the posts describe hacks to get around this issue.

You can use Javascript to dynamically set the height to 100% of the window and then center it using a negative left margin based on the ratio of video width to window width.
var $video = $('video'),
$window = $(window);
$(window).resize(function(){
var height = $window.height();
$video.css('height', height);
var videoWidth = $video.width(),
windowWidth = $window.width(),
marginLeftAdjust = (windowWidth - videoWidth) / 2;
$video.css({
'height': height,
'marginLeft' : marginLeftAdjust
});
}).resize();
An instance of Date always represents a date and cannot be empty. You can use a null value of date2 to represent "there is no date". You will have to check for null whenever you use date2 to avoid a NullPointerException, like when rendering your page:
if (date2 != null)
// print date2
else
// print nothing, or a default value
private EditText edt_firstName;
private String firstName;
edt_firstName = findViewById(R.id.edt_firstName);
private void validateData() {
firstName = edt_firstName.getText().toString().trim();
if (!firstName.isEmpty(){
//here api call for ....
}else{
if (firstName.isEmpty()) {
edt_firstName.setError("Please Enter First Name");
edt_firstName.requestFocus();
}

There are a lot of answers that are now outdated. The desired way of changing the heap size for Android Studio recently changed.
Users should now create their own vmoptions file in one of the following directories;
Windows:
%USERPROFILE%\.{FOLDER_NAME}\studio64.exe.vmoptions
Mac:
~/Library/Preferences/{FOLDER_NAME}/studio.vmoptions
Linux:
~/.{FOLDER_NAME}/studio.vmoptions and/or ~/.{FOLDER_NAME}/studio64.vmoptions
The contents of the newly created *.vmoptions
file should be:
-Xms128m
-Xmx750m
-XX:MaxPermSize=350m
-XX:ReservedCodeCacheSize=96m
-XX:+UseCompressedOops
To increase the RAM allotment change -XmX750m
to another value.

Just in my own words, your parent-project
helps you provide 2 kind of dependencies:
<dependencies>
section in your parent-project
are inherited by all the child-projects
child-projects
. Thus, you use the <dependencyManagement>
section, to declare all the dependencies you are going to use in your different child-projects
. The most important thing is that, in this section, you define a <version>
so that you don't have to declare it again in your child-project
.The <dependencyManagement>
in my point of view (correct me if I am wrong) is just useful by helping you centralize the version of your dependencies. It is like a kind of helper feature.
As a best practice, your <dependencyManagement>
has to be in a parent project, that other projects will inherit. A typical example is the way you create your Spring project by declaring the Spring parent project.
I think someone should face the same problem that can't find out the branch, although it actually exists in one branch.
You'd better pull all first:
git pull --all
Then do the branch search:
git name-rev <SHA>
or:
git branch --contains <SHA>
Just for fun ill post an alternative working answer for the OP's question:
cmake -DOPENSSL_ROOT_DIR=/usr/local/opt/openssl/ -DOPENSSL_CRYPTO_LIBRARY=/usr/local/opt/openssl/lib/
Building and simplifying @kindall's answer, here's what I typically use:
v_print = None
def main()
parser = argparse.ArgumentParser()
parser.add_argument('-v', '--verbosity', action="count",
help="increase output verbosity (e.g., -vv is more than -v)")
args = parser.parse_args()
if args.verbosity:
def _v_print(*verb_args):
if verb_args[0] > (3 - args.verbosity):
print verb_args[1]
else:
_v_print = lambda *a: None # do-nothing function
global v_print
v_print = _v_print
if __name__ == '__main__':
main()
This then provides the following usage throughout your script:
v_print(1, "INFO message")
v_print(2, "WARN message")
v_print(3, "ERROR message")
And your script can be called like this:
% python verbose-tester.py -v
ERROR message
% python verbose=tester.py -vv
WARN message
ERROR message
% python verbose-tester.py -vvv
INFO message
WARN message
ERROR message
A couple notes:

that sets the upper bound for your logging, but I accept that as a compromise for simplicity.v_print
to work throughout your program, you have to do the junk with the global. It's no fun, but I challenge somebody to find a better way.Use compile 'com.android.support:cardview-v7:25.4.0'
If you want version 26 you should use compile 'com.android.support:cardview-v7:26.0.0-beta2'
, because it is beta for now
Assuming you're using the mysql_ or mysqli_ functions, your question should already have been answered by others.
However if you're using PDO, there is no easy function to return the number of rows retrieved by a select statement, unfortunately. You have to use count() on the resultset (after assigning it to a local variable, usually).
Or if you're only interested in the number and not the data, PDOStatement::fetchColumn() on your SELECT COUNT(1)... result.
If your system is using SELinux, make sure that you use the right context for the directory you created:
ls -dZ /data/db/
ls -dZ /var/lib/mongo/
and clone the context with:
chcon -R --reference=/var/lib/mongo /data/db
if it's not a foreign key field, not using empty strings could save you some trouble. only allow nulls if you'll take null to mean something different than an empty string. for example if you have a password field, a null value could indicate that a new user has not created his password yet while an empty varchar could indicate a blank password. for a field like "address2" allowing nulls can only make life difficult. things to watch out for include null references and unexpected results of = and <> operators mentioned by Vagif Verdi, and watching out for these things is often unnecessary programmer overhead.
edit: if performance is an issue see this related question: Nullable vs. non-null varchar data types - which is faster for queries?
add
and remove
methods are easier to use. They update the data in the list and call notifyDataSetChanged in background.
Sample code:
adapter.add("your object");
adapter.remove("your object");
You can do it with DOCTYPE
, but you have to use table
. Check this out:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">
<head>
<style>
*{margin:0;padding:0}
html, body {height:100%;width:100%;overflow:hidden}
table {height:100%;width:100%;table-layout:static;border-collapse:collapse}
iframe {height:100%;width:100%}
.header {border-bottom:1px solid #000}
.content {height:100%}
</style>
</head>
<body>
<table>
<tr><td class="header"><div><h1>Header</h1></div></td></tr>
<tr><td class="content">
<iframe src="http://google.com/" frameborder="0"></iframe></td></tr>
</table>
</body>

Unfortunately MySQL does not feature a split string function. However you can create a user defined function for this, such as the one described in the following article:
With that function:
DELIMITER $$
CREATE FUNCTION SPLIT_STR(
x VARCHAR(255),
delim VARCHAR(12),
pos INT
)
RETURNS VARCHAR(255) DETERMINISTIC
BEGIN
RETURN REPLACE(SUBSTRING(SUBSTRING_INDEX(x, delim, pos),
LENGTH(SUBSTRING_INDEX(x, delim, pos -1)) + 1),
delim, '');
END$$
DELIMITER ;
you would be able to build your query as follows:
SELECT SPLIT_STR(membername, ' ', 1) as memberfirst,
SPLIT_STR(membername, ' ', 2) as memberlast
FROM users;
If you prefer not to use a user defined function and you do not mind the query to be a bit more verbose, you can also do the following:
SELECT SUBSTRING_INDEX(SUBSTRING_INDEX(membername, ' ', 1), ' ', -1) as memberfirst,
SUBSTRING_INDEX(SUBSTRING_INDEX(membername, ' ', 2), ' ', -1) as memberlast
FROM users;
$(document).ready
happens when all the elements are present in the DOM, but not necessarily all content.
$(document).ready(function() {
alert("document is ready");
});
window.onload
or $(window).load()
happens after all the content resources (images, etc) have been loaded.
$(window).load(function() {
alert("window is loaded");
});
Relying on compiler optimizations is fragile. The benchmarks linked in the accepted answer and numbers given by Antoine-tran are not to be trusted. Andrew Hare makes the mistake of including a call to repr
in his methods. That slows all the methods equally but obscures the real penalty in constructing the string.
Use join
. It's very fast and more robust.

in the manifest.
Reported to be available even when Wi-Fi is not connected. If Joe from the answer above gives this one a try on his many devices, that'd be nice.
On some devices, it's not available when Wi-Fi is turned off.
NOTE: From Android 6.x, it returns consistent fake mac address: 02:00:00:00:00:00
for more extendability for large scale apps use oop style with encapsulated fields.
Simple way :-
class Fruit implements JsonSerializable {
private $type = 'Apple', $lastEaten = null;
public function __construct() {
$this->lastEaten = new DateTime();
}
public function jsonSerialize() {
return [
'category' => $this->type,
'EatenTime' => $this->lastEaten->format(DateTime::ISO8601)
];
}
}
echo json_encode(new Fruit()); //which outputs:
{"category":"Apple","EatenTime":"2013-01-31T11:17:07-0500"}

This article might be helpful with changing fonts.
From the article:
The commands to change font attributes are illustrated by the following example:
\fontencoding{T1}
\fontfamily{garamond}
\fontseries{m}
\fontshape{it}
\fontsize{12}{15}
\selectfont
This series of commands set the current font to medium weight italic garamond 12pt type with 15pt leading in the T1 encoding scheme, and the \selectfont command causes LaTeX to look in its mapping scheme for a metric corresponding to these attributes.

I think this is an update. I was unable to install rJava (on Windows) until I installed the JDK, as per Javac is not found and javac not working in windows command prompt. The message I was getting was
'javac' is not recognized as an internal or external command, operable program or batch file.
The JDK includes the JRE, and according to https://cran.r-project.org/web/packages/rJava/index.html the current version (0.9-7 published 2015-Jul-29) of rJava
SystemRequirements: Java JDK 1.2 or higher (for JRI/REngine JDK 1.4 or higher), GNU make
So there you are: if rJava won't install because it can't find javac, and you have the JRE installed, then try the JDK. Also, make sure that JAVA_HOME
points to the JDK and not the JRE.
set print elements 0
set print elements
number-of-elements
Set a limit on how many elements of an array GDB will print. If GDB is printing a large array, it stops printing after it has printed the number of elements set by the set print elements
command. This limit also applies to the display of strings. When GDB starts, this limit is set to 200. Setting number-of-elements to zero means that the printing is unlimited.
I know I am late to the party, but how about this?
const char* dayNames[] = { [Sunday] = "Sunday", [Monday] = "Monday", /*and so on*/ };
printf("%s", dayNames[Sunday]); // prints "Sunday"
This way, you do not have to manually keep the enum
and the char*
array in sync. If you are like me, chances are that you will later change the enum
, and the char*
array will print invalid strings.
This may not be a feature universally supported. But afaik, most of the mordern day C compilers support this designated initialier style.

I was able to overcome this by using "gcc" instead of "g++" for my compiler. I know this isn't an option for most people, but thought I'd mention it as a workaround option :)
There are a number of tools available which help debugging segmentation faults and I would like to add my favorite tool to the list: Address Sanitizers (often abbreviated ASAN).
Modern¹ compilers come with the handy -fsanitize=address
flag, adding some compile time and run time overhead which does more error checking.
According to the documentation these checks include catching segmentation faults by default. The advantage here is that you get a stack trace similar to gdb's output, but without running the program inside a debugger. An example:
int main() {
volatile int *ptr = (int*)0;
*ptr = 0;
}
$ gcc -g -fsanitize=address main.c
$ ./a.out

The output is slightly more complicated than what gdb would output but there are upsides:
There is no need to reproduce the problem to receive a stack trace. Simply enabling the flag during development is enough.
ASANs catch a lot more than just segmentation faults. Many out of bounds accesses will be caught even if that memory area was accessible to the process.

Try this:
var i = 3;
$('#my_table > tbody > tr:eq(' + i + ')').after(html);
or this:

$('#my_table > tbody > tr').eq( i ).after(html);
or this:
var i = 4;
$('#my_table > tbody > tr:nth-child(' + i + ')').after(html);
All of these will place the row in the same position. nth-child

COUNT(items.item_id) AS num_items
FROM
people
INNER JOIN orders ON orders.pe_id = people.pe_id
INNER JOIN items ON items.ord_id = orders.ord_id
GROUP BY
people.pe_id;
Joining the items with the people provokes a lot of doublons. For example, the cake items in order 3 will be linked with the order 2 via the join between the people, and you don't want this to happen !!
So :
1- You need a good understanding of your schema. Items are link to orders, and not to people.
2- You need to count distinct orders for one person, else you will count as many items as orders.
you should add plug in to your local setting of firefox in your user home

I had this problem in android and i use this way (Work for me):
String test = null;
if(test == "null"){
// Do work
}
But in java code I use :
String test = null;
if(test == null){
// Do work
}
And :
private Integer compareDateStrings(BeanToDoTask arg0, BeanToDoTask arg1, String strProperty) {
String strDate0 = BeanUtils.getProperty(arg0, strProperty);_logger.debug("strDate0 = " + strDate0);
String strDate1 = BeanUtils.getProperty(arg1, strProperty);_logger.debug("strDate1 = " + strDate1);
return compareDateStrings(strDate0, strDate1);
}
private Integer compareDateStrings(String strDate0, String strDate1) {
int cmp = 0;
if (isEmpty(strDate0)) {
if (isNotEmpty(strDate1)) {
cmp = -1;
} else {
cmp = 0;
}
} else if (isEmpty(strDate1)) {
cmp = 1;
} else {
cmp = strDate0.compareTo(strDate1);
}
return cmp;
}
private boolean isEmpty(String str) {
return str == null || str.isEmpty();
}
private boolean isNotEmpty(String str) {
return !isEmpty(str);
}
Try to do this:
SQL> select dept,count(*) "no of emp" from employee group by dept;
DEPT no of emp
-------------------- ----------
HR 2
Account 2
Admin 3
Using %lf
will help you in solving this problem.
Use :
scanf("%lf",&doub)
You can use PowerShell to run b.bat as administrator from a.bat
:
set mydir=%~dp0
Powershell -Command "& { Start-Process \"%mydir%b.bat\" -verb RunAs}"
It will prompt the user with a confirmation dialog. The user chooses YES
, and then b.bat
will be run as administrator.
You're trying to connect to localhost:8080 ... is any service running on your localhost and on this port? If not, the connection is refused which cause this error. I would suggest to check if there is anything running on localhost:8080 first.
You could just use this
FileOpen(1, "C:\my files\2010\SomeFileName.txt", OpenMode.Output)
FileClose(1)
This opens the file replaces whatever is in it and closes the file.
Here's a solution that worked for me. It's a blend of the solution by PolyMesh and use of the new .format()
syntax.
for num in 3, 3., 3.0, 3.1, 3.14, 3.140:
print('{0:.2f}'.format(num).rstrip('0').rstrip('.'))
Output:
3
3
3
3.1
3.14
3.14
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"
If your ID is unique identifier type or your id in table is not sorted you must do like this below.
select * from
(select ROW_NUMBER() OVER (ORDER BY (select 0)) AS RowNumber,* from table1) a
where a.RowNumber between 2 and 5
The code will be
select * from limit 2,5
This problem can also happen in Windows. Cmake looks into the registry and sometimes python values are not set. For those with similar problem:
http://ericsilva.org/2012/10/11/restoring-your-python-registry-in-windows/
Just create a .reg file to set the necessary keys and edit accordingly to match your setup.

Although this has been answer https://stackoverflow.com/a/28375912/5413283, and regarding padding it is not mentioned in the original answer but here https://stackoverflow.com/a/33697157/5413283.
i am just adding here for visual presentation and a cleaner code.
Create a new parent div and add the bootstrap collapse. Remove the classes from the textarea
<div class="collapse" id="collapseOne"> <!-- bootstrap class on parent -->
<textarea class="form-control" rows="4"></textarea>
</div> <!-- // bootstrap class on parent -->
If you want to have spaces around, wrap textarea
with padding. Do not add margin
, it has the same issue.
<div class="collapse" id="collapseOne"> <!-- bootstrap class on parent -->
<div class="py-4"> <!-- padding for textarea -->
<textarea class="form-control" rows="4"></textarea>
</div> <!-- // padding for textarea -->
</div> <!-- // bootstrap class on parent -->
Same as bootstrap 4. Wrap the textare
with collapse
class.
<div class="collapse" id="collapseOne"> <!-- bootstrap class on parent -->
<textarea class="form-control" rows="4"></textarea>
</div> <!-- // bootstrap class on parent -->
And for padding
Bootstrap 3 does not have p-* classes like Bootstrap 4 . So you need to create your own. Do not use padding
it will not work, use margin
.
#collapseOne textarea {
margin: 10px 0 10px 0;
}
Use .net inbuilt class JavaScriptSerializer
JavaScriptSerializer js = new JavaScriptSerializer();
string json = js.Serialize(obj);
You can subtract the time zone difference from now.
final Calendar calendar = Calendar.getInstance();
final int utcOffset = calendar.get(Calendar.ZONE_OFFSET) + calendar.get(Calendar.DST_OFFSET);
final long tempDate = new Date().getTime();
return new Date(tempDate - utcOffset);
This is how I would do it, you don't need get-content:
ls -r | Select-String dummy | select line,path
or
ls -r | Select-String dummy | fl *
To see what the different properties are...
This is faster. The second argument is -filter:
ls -r . *.bat | select-string netsh
ls -r . -filter *.bat | select-string netsh
You probably are looking for AddReference dialog accessible from Project Context Menu (right click..)
From there you can reference dll's, after which you can reference namespaces that you need in your code.
You can easily crop a Mat using opencv funtions.
setMouseCallback("Original",mouse_call);
The mouse_call
is given below:
void mouse_call(int event,int x,int y,int,void*)
{
if(event==EVENT_LBUTTONDOWN)
{
leftDown=true;
cor1.x=x;
cor1.y=y;
cout <<"Corner 1: "<<cor1<<endl;
}
if(event==EVENT_LBUTTONUP)
{
if(abs(x-cor1.x)>20&&abs(y-cor1.y)>20) //checking whether the region is too small
{
leftup=true;
cor2.x=x;
cor2.y=y;
cout<<"Corner 2: "<<cor2<<endl;
}
else
{
cout<<"Select a region more than 20 pixels"<<endl;
}
}
if(leftDown==true&&leftup==false) //when the left button is down
{
Point pt;
pt.x=x;
pt.y=y;
Mat temp_img=img.clone();
rectangle(temp_img,cor1,pt,Scalar(0,0,255)); //drawing a rectangle continuously
imshow("Original",temp_img);
}
if(leftDown==true&&leftup==true) //when the selection is done
{
box.width=abs(cor1.x-cor2.x);
box.height=abs(cor1.y-cor2.y);
box.x=min(cor1.x,cor2.x);
box.y=min(cor1.y,cor2.y);
Mat crop(img,box); //Selecting a ROI(region of interest) from the original pic
namedWindow("Cropped Image");
imshow("Cropped Image",crop); //showing the cropped image
leftDown=false;
leftup=false;
}
}
For details you can visit the link Cropping the Image using Mouse
function hasSpaces(str) {
if (str.indexOf(' ') !== -1) {
return true
} else {
return false
}
}
Test if the object implements either java.util.Collection
or java.util.Map
. (Map
has to be tested separately because it isn't a sub-interface of Collection
.)
You can use a CSS3 transition
for this. Have a look at this example:
Here is the main code:
#box {
position : relative;
width : 100px;
height : 100px;
background-color : gray;
border : 5px solid black;
-webkit-transition : border 500ms ease-out;
-moz-transition : border 500ms ease-out;
-o-transition : border 500ms ease-out;
transition : border 500ms ease-out;
}
#box:hover {
border : 10px solid red;
}
Here is one possible way of doing this based on the assumption that there will not be any blank sheets in the Excel files and also all the sheets follow the exact same structure. Also, under the assumption that the file extension is only .xlsx
Following example was created using SSIS 2008 R2 and Excel 2007. The working folder for this example is F:\Temp\
In the folder path F:\Temp\
, create an Excel 2007 spreadsheet file named States_1.xlsx
with two worksheets.
Sheet 1
of States_1.xlsx contained the following data
Sheet 2
of States_1.xlsx contained the following data
In the folder path F:\Temp\
, create another Excel 2007 spreadsheet file named States_2.xlsx
with two worksheets.
Sheet 1
of States_2.xlsx contained the following data
Sheet 2
of States_2.xlsx contained the following data
Create a table in SQL Server named dbo.Destination using the below create script. Excel sheet data will be inserted into this table.
CREATE TABLE [dbo].[Destination](
[Id] [int] IDENTITY(1,1) NOT NULL,
[State] [nvarchar](255) NULL,
[Country] [nvarchar](255) NULL,
[FilePath] [nvarchar](255) NULL,
[SheetName] [nvarchar](255) NULL,
CONSTRAINT [PK_Destination] PRIMARY KEY CLUSTERED ([Id] ASC)) ON [PRIMARY]
GO
The table is currently empty.
Create a new SSIS package and on the package, create the following 4 variables. FolderPath will contain the folder where the Excel files are stored. FilePattern will contain the extension of the files that will be looped through and this example works only for .xlsx
. FilePath will be assigned with a value by the Foreach Loop container but we need a valid path to begin with for design time and it is currently populated with the path F:\Temp\States_1.xlsx
of the first Excel file. SheetName will contain the actual sheet name but we need to populate with initial value Sheet1$
to avoid design time error.
In the package's connection manager, create an ADO.NET connection with the following configuration and name it as ExcelSchema.
Select the provider Microsoft Office 12.0 Access Database Engine OLE DB Provider
under .Net Providers for OleDb. Provide the file path F:\Temp\States_1.xlsx
Click on the All
section on the left side and set the property Extended Properties to Excel 12.0
to denote the version of Excel. Here in this case 12.0 denotes Excel 2007
. Click on the Test Connection to make sure that the connection succeeds.
Create an Excel connection manager named Excel as shown below.
Create an OLE DB Connection SQL Server named SQLServer
. So, we should have three connections on the package as shown below.
We need to do the following connection string changes so that the Excel file is dynamically changed as the files are looped through.
On the connection ExcelSchema, configure the expression ServerName
to use the variable FilePath
. Click on the ellipsis button to configure the expression.
Similarly on the connection Excel, configure the expression ServerName
to use the variable FilePath
. Click on the ellipsis button to configure the expression.
On the Control Flow, place two Foreach Loop containers one within the other. The first Foreach Loop container
named Loop files will loop through the files. The second Foreach Loop container
will through the sheets within the container. Within the inner For each loop container, place a Data Flow Task that will read the Excel files and load data into SQL
Configure the first Foreach loop container named Loop files as shown below:
Configure the first Foreach loop container named Loop sheets as shown below:
Inside the data flow task, place an Excel Source, Derived Column and OLE DB Destination as shown below:
Configure the Excel Source to read the appropriate Excel file and the sheet that is currently being looped through.
Configure the derived column to create new columns for file name and sheet name. This is just to demonstrate this example but has no significance.
Configure the OLE DB destination to insert the data into the SQL table.
Below screenshot shows successful execution of the package.
Below screenshot shows that data from the 4 workbooks in 2 Excel spreadsheets that were creating in the beginning of this answer is correctly loaded into the SQL table dbo.Destination.
Hope that helps.

I used LD_LIBRARY_PATH
variable to priorities the path picked up by the linker to search the required lib.
I copied both service and .so

variable as
LD_LIBRARY_PATH=. ./service
being in the same folder I have given the above command and it worked.
Have to add this based on @Joseph's answer. If someone want to create image object:
var image = new Image();
image.onload = function(){
console.log(image.width); // image is loaded and we have image width
}
image.src = 'data:image/png;base64,iVBORw0K...';
document.body.appendChild(image);
$ ruby -ne 'puts $_.scan(/id=(\d+)/)' file

You can use selectedOptions
var selectedValues = Array.from(document.getElementById('select-meal-type').selectedOptions).map(el=>el.value);
console.log(selectedValues);

This is the strict aliasing rule, found in section 3.10 of the C++03 standard (other answers provide good explanation, but none provided the rule itself):
If a program attempts to access the stored value of an object through an lvalue of other than one of the following types the behavior is undefined:
- the dynamic type of the object,
- a cv-qualified version of the dynamic type of the object,
- a type that is the signed or unsigned type corresponding to the dynamic type of the object,
- a type that is the signed or unsigned type corresponding to a cv-qualified version of the dynamic type of the object,
- an aggregate or union type that includes one of the aforementioned types among its members (including, recursively, a member of a subaggregate or contained union),
- a type that is a (possibly cv-qualified) base class type of the dynamic type of the object,
- a
char
orunsigned char
type.
C++11 and C++14 wording (changes emphasized):
If a program attempts to access the stored value of an object through a glvalue of other than one of the following types the behavior is undefined:
- the dynamic type of the object,
- a cv-qualified version of the dynamic type of the object,
- a type similar (as defined in 4.4) to the dynamic type of the object,
- a type that is the signed or unsigned type corresponding to the dynamic type of the object,
- a type that is the signed or unsigned type corresponding to a cv-qualified version of the dynamic type of the object,
- an aggregate or union type that includes one of the aforementioned types among its elements or non-static data members (including, recursively, an element or non-static data member of a subaggregate or contained union),
- a type that is a (possibly cv-qualified) base class type of the dynamic type of the object,
- a
char
orunsigned char
type.
Two changes were small: glvalue instead of lvalue, and clarification of the aggregate/union case.
The third change makes a stronger guarantee (relaxes the strong aliasing rule): The new concept of similar types that are now safe to alias.
Also the C wording (C99; ISO/IEC 9899:1999 6.5/7; the exact same wording is used in ISO/IEC 9899:2011 §6.5 ¶7):
An object shall have its stored value accessed only by an lvalue expression that has one of the following types 73) or 88):
- a type compatible with the effective type of the object,
- a quali?ed version of a type compatible with the effective type of the object,
- a type that is the signed or unsigned type corresponding to the effective type of the object,
- a type that is the signed or unsigned type corresponding to a quali?ed version of the effective type of the object,
- an aggregate or union type that includes one of the aforementioned types among its members (including, recursively, a member of a subaggregate or contained union), or
- a character type.
73) or 88) The intent of this list is to specify those circumstances in which an object may or may not be aliased.

Available parameters:
Use the following in the function you will call and it will work just fine.
[a b c] = yourfunction(optional)
%your code
a = 5;
b = 7;
c = 10;
return
end
This is a way to call the function both from another function and from the command terminal
[aa bb cc] = yourfunction(optional);
The variables aa, bb and cc now hold the return variables.

Consider this script, called funcdemo
:
#!/bin/bash
[ $# = 0 ] && exhort "write nastygram"
exhort(){
echo "Please, please do not forget to $*"

[ $# != 0 ] && exhort "write begging letter"
In use:
$ funcdemo

Note the potential for a missing function to lie undiscovered for a long time (think 'by a customer at the most critical wrong moment'). It only matters whether the function exists when it is executed, the same as it only matters whether any other command exists when you try to execute it. Indeed, until it goes to execute the command, the shell neither knows nor cares whether it is an external command or a function.

Because all the dependencies are clearly visible, it promotes creating components which are loosely coupled and at the same time easily accessible and reusable across the application.
Although answer has been already provided by @brabster and others.
I think more reusable solution would be:
<xsl:variable name="space"> </xsl:variable>
...
<xsl:value-of select="$space"/>
Quick helper method that might address this situation:
<T> T onlyItem(Collection<T> items) {
if (items.size() != 1)
throw new IllegalArgumentException("Collection must have single item; instead it has " + items.size());
return items.iterator().next();
}
First of all ASP.NET MVC does not work the same way WebForms does. You don't have the whole runat="server"
thing. MVC does not offer the abstraction layer that WebForms offered. Probabaly you should try to understand what controllers and actions are and then you should look at model binding. Any beginner level tutorial about MVC shows how you can pass data between the client and the server.
To convert any object or object list into JSON, we have to use the function JsonConvert.SerializeObject.
The below code demonstrates the use of JSON in an ASP.NET environment:
using System;
using System.Data;
using System.Configuration;
using System.Collections;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;
using Newtonsoft.Json;
using System.Collections.Generic;
namespace JSONFromCS
{
public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e1)
{
List<Employee> eList = new List<Employee>();
Employee e = new Employee();
e.Name = "Minal";
e.Age = 24;
eList.Add(e);
e = new Employee();
e.Name = "Santosh";
e.Age = 24;
eList.Add(e);
string ans = JsonConvert.SerializeObject(eList, Formatting.Indented);
string script = "var employeeList = {\"Employee\": " + ans+"};";
script += "for(i = 0;i<employeeList.Employee.length;i++)";
script += "{";
script += "alert ('Name : ='+employeeList.Employee[i].Name+'
Age : = '+employeeList.Employee[i].Age);";
script += "}";
ClientScriptManager cs = Page.ClientScript;
cs.RegisterStartupScript(Page.GetType(), "JSON", script, true);
}
}
public class Employee
{
public string Name;
public int Age;
}
}
After running this program, you will get two alerts
In the above example, we have created a list of Employee object and passed it to function "JsonConvert.SerializeObject". This function (JSON library) will convert the object list into JSON format. The actual format of JSON can be viewed in the below code snippet:
{ "Maths" : [ {"Name" : "Minal", // First element
"Marks" : 84,
"age" : 23 },
{
"Name" : "Santosh", // Second element
"Marks" : 91,
"age" : 24 }
],
"Science" : [
{
"Name" : "Sahoo", // First Element
"Marks" : 74,
"age" : 27 },
{
"Name" : "Santosh", // Second Element
"Marks" : 78,
"age" : 41 }
]
}
Syntax:
{} - acts as 'containers'
[] - holds arrays
: - Names and values are separated by a colon
, - Array elements are separated by commas
This code is meant for intermediate programmers, who want to use C# 2.0 to create JSON and use in ASPX pages.
You can create JSON from JavaScript end, but what would you do to convert the list of object into equivalent JSON string from C#. That's why I have written this article.
In C# 3.5, there is an inbuilt class used to create JSON named JavaScriptSerializer.
The following code demonstrates how to use that class to convert into JSON in C#3.5.
JavaScriptSerializer serializer = new JavaScriptSerializer()
return serializer.Serialize(YOURLIST);
So, try to create a List of arrays with Questions and then serialize this list into JSON

List<String> args = new ArrayList<String>();
args.add ("script.bat"); // command name
args.add ("-option"); // optional args added as separate list items
ProcessBuilder pb = new ProcessBuilder (args);
Process p = pb.start();
p.waitFor();
the waitFor()
method will wait until the process had ended before continuing. This method returns the error code of the process but, since you don't care about it, I didn't put it in the example.
You will have to change some of your data types but the basics of what you just posted could be converted to something similar to this given the data types I used may not be accurate.
Dim DateToday As String: DateToday = Format(Date, "yyyy/MM/dd")
Dim Computers As New Collection
Dim disabledList As New Collection
Dim compArray(1 To 1) As String
'Assign data to first item in array
compArray(1) = "asdf"
'Format = Item, Key
Computers.Add "ErrorState", "Computer Name"
'Prints "ErrorState"
Debug.Print Computers("Computer Name")
Collections cannot be sorted so if you need to sort data you will probably want to use an array.

Another great site to help you get started is http://www.cpearson.com/Excel/Topic.aspx
Moving everything over to VBA from VB.Net is not going to be simple since not all the data types are the same and you do not have the .Net framework. If you get stuck just post the code you're stuck converting and you will surely get some help!
Edit:
Sub ArrayExample()
Dim subject As String
Dim TestArray() As String
Dim counter As Long
subject = "Example"
counter = Len(subject)
ReDim TestArray(1 To counter) As String
For counter = 1 To Len(subject)
TestArray(counter) = Right(Left(subject, counter), 1)
Next
End Sub
you put resource-ref in the description tag in web.xml
A connection timeout occurs only upon starting the TCP connection. This usually happens if the remote machine does not answer. This means that the server has been shut down, you used the wrong IP/DNS name, wrong port or the network connection to the server is down.
A socket timeout is dedicated to monitor the continuous incoming data flow. If the data flow is interrupted for the specified timeout the connection is regarded as stalled/broken. Of course this only works with connections where data is received all the time.
By setting socket timeout to 1 this would require that every millisecond new data is received (assuming that you read the data block wise and the block is large enough)!
If only the incoming stream stalls for more than a millisecond you are running into a timeout.
I would suggest it might be better to use ajax and load the svg element from another page.
$('.container').load(href + ' .svg_element');
Where href is the location of the page with the svg. This way you can avoid any jittery effects that might occur from replacing the html content. Also, don't forget to unwrap the svg after it's loaded:
$('.svg_element').unwrap();
@Adrian's answer is perfectly suitable, I just wanted to share another way of achieving the same result:
select nvl(a.id, b.id)
from a full outer join b on a.id = b.id
order by b.id;
From IE7 onwards you can simply use
#footer {
position:fixed;
bottom:0;
}
See caniuse for support.
Class.isAssignableFrom()
- works for interfaces as well. If you don't want that, you'll have to call getSuperclass()
and test until you reach Object
.
This should display the image inline:
.content-dir-item img.mail {
display: inline-block;
*display: inline; /* for older IE */
*zoom: 1; /* for older IE */
}
=Join(Parameters!Product.Label, vbcrfl) for new line
I have been struggling on this issue for two days, sharing my solution here in case anyone may need it.
The VMs that I'm using are Standard N-series GPU server with 2 K80 cards on Azure platform. With Ubuntu 18.04 OS installed.
Apparently there is an update of linux kernel several days before I came across this issue, and after the update the driver stopped working.
At first, I did purge and re-install as above replies suggested. Nothing works. Out of sudden(I don't remember why I wanted to do it), I updated the default gcc and g++ version on one of my VM as following.
sudo apt install software-properties-common
sudo add-apt-repository ppa:ubuntu-toolchain-r/test
sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-9 90
sudo update-alternatives --install /usr/bin/g++ g++ /usr/bin/g++-9 90
Then I purged the nvidia softwares and reinstall it as instructed in official document(please choose the correct one for your system: https://developer.nvidia.com/cuda-downloads?target_os=Linux&target_arch=x86_64&target_distro=Ubuntu&target_version=1804&target_type=deblocal) again.
sudo apt-get purge nvidia-*
Then the nvidia-smi command finally worked again.
PS:
If you are using Azure linux VM like me. The recommended way to install CUDA is actually by enabling "NVIDIA GPU Driver Extension" in the Azure portal (of course, after you have configured the correct gcc version).
I have tried this way on my another VM and It works as well.
How about adding line-height
?
#abc{
font:Verdana, Geneva, sans-serif;
font-size:18px;
text-align:left;
background-color:#0F0;
height:50px;
vertical-align:middle;
line-height: 45px;
}
Or padding
on #abc
. This is the result with padding
Update
Add in your css :
#abc img{
vertical-align: middle;
}
The result. Hope this what you looking for.
I use this function merge
CREATE OR REPLACE FUNCTION merge_tabla(key INT, data TEXT)
RETURNS void AS
$BODY$
BEGIN
IF EXISTS(SELECT a FROM tabla WHERE a = key)
THEN
UPDATE tabla SET b = data WHERE a = key;
RETURN;
ELSE
INSERT INTO tabla(a,b) VALUES (key, data);
RETURN;
END IF;
END;
$BODY$

md5sum
worked fine for me, but I had issues with sort
and sorting file names. So instead I sorted by md5sum
result. I also needed to exclude some files in order to create comparable results.
find . -type f -print0 \
| xargs -r0 md5sum \
| grep -v ".env" \
| grep -v "vendor/autoload.php" \
| grep -v "vendor/composer/" \
| sort -d \
| md5sum
c_str
returns a const char*
that points to a null-terminated string (i.e. a C-style string). It is useful when you want to pass the "contents"¹ of an std::string
to a function that expects to work with a C-style string.
For example, consider this code:
std::string str("Hello world!");
int pos1 = str.find_first_of('w');
int pos2 = strchr(str.c_str(), 'w') - str.c_str();
if (pos1 == pos2) {
printf("Both ways give the same result.\n");
}
Notes:
¹ This is not entirely true because an std::string
(unlike a C string) can contain the \0
character. If it does, the code that receives the return value of c_str()
will be fooled into thinking that the string is shorter than it really is, since it will interpret \0
as the end of the string.
Everything you need here can be found in this quickstart guide.
A straightforward solution would be [A-Za-z][A-Za-z]\d\d\d\d\d\d
or [A-Za-z]{2}\d{6}
.
If you want to accept only capital letters then replace [A-Za-z]
with [A-Z]
.

Yes, for scalar values, a combination of implode and array_slice will do:
$bar = implode(array_slice($array, 0, 1));
$bin = implode(array_slice($array, 1, 1));
$ipsum = implode(array_slice($array, 2, 1));
Or mix it up with array_values
and list
(thanks @nikic) so that it works with all types of values:
list($bar) = array_values(array_slice($array, 0, 1));
This should work for alpha 6. The key is the class "mr-auto" on the left nav, which will push the right nav to the right. You also need to add navbar-toggleable-md or it will stack in a column instead of a row. Note I didn't add the remaining toggle items (e.g. toggle button), I added just enough to get it to formatted as requested. Here are more complete examples https://v4-alpha.getbootstrap.com/examples/navbars/.

This problem happens when older versions of java still on your system disrupt any new versions installed. To stop this problem you need to first remove all java software using - Control Panel + Remove Programs + then uninstall java. (At this stage, I recommend cleaning out your registry using CCleaner using their Registry option or similar program to ensure a clean sweep then reboot) After rebooting reinstall the most recent version of java and all will be well.

for this problem:
use this:
*{
-webkit-tap-highlight-color: rgba(0,0,0,0);
-webkit-tap-highlight-color: transparent; /* For some Androids */
}
result:
Here is a simple recursive algorithm in python for finding all subsets of a set:
def find_subsets(so_far, rest):
print 'parameters', so_far, rest
if not rest:
print so_far
else:
find_subsets(so_far + [rest[0]], rest[1:])
find_subsets(so_far, rest[1:])
find_subsets([], [1,2,3])
The output will be the following: $python subsets.py
parameters [] [1, 2, 3]
parameters [1] [2, 3]
parameters [1, 2] [3]
parameters [1, 2, 3] []
[1, 2, 3]
parameters [1, 2] []
[1, 2]
parameters [1] [3]
parameters [1, 3] []
[1, 3]
parameters [1] []
[1]
parameters [] [2, 3]
parameters [2] [3]
parameters [2, 3] []
[2, 3]
parameters [2] []
[2]
parameters [] [3]
parameters [3] []

Watch the following video from Stanford for a nice explanation of this algorithm:
https://www.youtube.com/watch?v=NdF1QDTRkck&feature=PlayList&p=FE6E58F856038C69&index=9
you can use
reader.GetInt32(3);
to read an 32 bit int from the data reader.
If you know the type of your data I think its better to read using the Get*
methods which are strongly typed rather than just reading an object and casting.
Have you considered using
reader.GetInt32(reader.GetOrdinal(columnName))
rather than accessing by position. This makes your code less brittle and will not break if you change the query to add new columns before the existing ones. If you are going to do this in a loop, cache the ordinal first.
you can also use a hashmap for this
@GetMapping
public HashMap<String, Object> get() {
HashMap<String, Object> map = new HashMap<>();
map.put("key1", "value1");
map.put("results", somePOJO);
return map;
}
this
is used to access the methods and fields of the current object. For this reason, it has no meaning in static methods, for example.
super
allows access to non-private methods and fields in the super-class, and to access constructors from within the class' constructors only.
You did everything correctly!
You might also change the email configuration, depending on if the email server is also the same server. The email configuration is in gitlab.yml for the mails sent by GitLab and also the admin-email.
Your submodule history is safely preserved in the submodule git anyway.
So, why not just delete the submodule and add it again?
Otherwise, did you try manually editing the HEAD
or the refs/master/head
within the submodule .git
If you have a MUTABLE collection:
val list = mutableListOf(1, 2, 3)
list += 4
If you have an IMMUTABLE collection:
var list = listOf(1, 2, 3)
list += 4
note that I use val
for the mutable list to emphasize that the object is always the same, but its content changes.
In case of the immutable list, you have to make it var
. A new object is created by the +=
operator with the additional value.
In my case it was an issue with the configuration file web.config on my machine when I updated the newton version VS automatically fixed my web.config file to point to the new version. When I uploaded it to production the existing web.config was pointing to the old version.
Once I updated the web.config it started working again.

Setup:
My OS windows 8 64bit
Eclipse version Standard/SDK Kepler Service Release 2
My JDK is jdk-8u5-windows-i586
My JRE is jre-8u5-windows-i586
This how I overcome my error.
At the very first my Class.forName("sun.jdbc.odbc.JdbcOdbcDriver")
also didn't work.
Then I login to this website and downloaded the UCanAccess 2.0.8 zip (as Mr.Gord Thompson said) file and unzip it.
Then you will also able to find these *.jar files in that unzip folder:
ucanaccess-2.0.8.jar
commons-lang-2.6.jar
commons-logging-1.1.1.jar
hsqldb.jar
jackcess-2.0.4.jar
Then what I did was I copied all these 5 files and paste them in these 2 locations:
C:\Program Files (x86)\eclipse\lib
C:\Program Files (x86)\eclipse\lib\ext
(I did that funny thing becoz I was unable to import these libraries to my project)
Then I reopen the eclipse with my project.then I see all that *.jar files in my project's JRE System Library folder.
Finally my code works.
public static void main(String[] args)
{
try
{
Connection conn=DriverManager.getConnection("jdbc:ucanaccess://C:\\Users\\Hasith\\Documents\\JavaDatabase1.mdb");
Statement stment = conn.createStatement();
String qry = "SELECT * FROM Table1";
ResultSet rs = stment.executeQuery(qry);
while(rs.next())
{
String id = rs.getString("ID") ;
String fname = rs.getString("Nama");
System.out.println(id + fname);
}
}
catch(Exception err)
{
System.out.println(err);
}
//System.out.println("Hasith Sithila");
}
What I always use is:
scp -r username@IP:/path/to/server/source/folder/ .
. (dot) : it means current folder
. so copy from server and paste here only.
IP : can be an IP address like 125.55.41.311
or it can be host like ns1.mysite.com
.
As none of the answers described a way to perform requests with OkHttp, which is very popular http client nowadays for Android and Java in general, I am going to provide a simple example:
//get an instance of the client
OkHttpClient client = new OkHttpClient();
//add parameters
HttpUrl.Builder urlBuilder = HttpUrl.parse("https://www.example.com").newBuilder();
urlBuilder.addQueryParameter("query", "stack-overflow");
String url = urlBuilder.build().toString();
//build the request
Request request = new Request.Builder().url(url).build();
//execute
Response response = client.newCall(request).execute();
The clear advantage of this library is that it abstracts us from some low level details, providing more friendly and secure ways to interact with them. The syntax is also simplified and permits to write nice code.
If you whant only one first string, you can use simple for-loop.
var lines = File.ReadAllLines(pathToTextFile);
var firstFound = false;
for(int index = 0; index < lines.Count; index++)
{
if(!firstFound && lines[index].Contains("CustomerEN"))
{
firstFound = true;
}
if(firstFound && lines[index].Contains("CustomerCh"))
{
//do, what you want, and exit the loop
// return lines[index];
}
}
That's the code I use:
<?php
$path="C:/foopath/";
$file="foofile.txt";
//read file contents
$content="
<h2>$file</h2>
<code>
<pre>".htmlspecialchars(file_get_contents("$path/$file"))."</pre>
</code>";
//display
echo $content;
?>
Keep in mind that if the user can modify $path or $file (for example via $_GET or $_POST), he/she will be able to see all your source files (danger!)
Imagine you have have a Book model and a Page model,
1:N means:
One book can have **many** pages. One page can only be in **one** book.
N:N means:
One book can have **many** pages. And one page can be in **many** books.
I'm using rather specified charset (ISO-8859-2) because not every mail system (for example: http://10minutemail.com) can read UTF-8 mails. If you need this:
function utf8_to_latin2($str)
{
return iconv ( 'utf-8', 'ISO-8859-2' , $str );
}
function my_mail($to,$s,$text,$form, $reply)
{
mail($to,utf8_to_latin2($s),utf8_to_latin2($text),
"From: $form\r\n".
"Reply-To: $reply\r\n".
"X-Mailer: PHP/" . phpversion());
}
I have made another mailer function, because apple device could not read well the previous version.
function utf8mail($to,$s,$body,$from_name="x",$from_a = "[email protected]", $reply="[email protected]")
{
$s= "=?utf-8?b?".base64_encode($s)."?=";
$headers = "MIME-Version: 1.0\r\n";
$headers.= "From: =?utf-8?b?".base64_encode($from_name)."?= <".$from_a.">\r\n";
$headers.= "Content-Type: text/plain;charset=utf-8\r\n";
$headers.= "Reply-To: $reply\r\n";
$headers.= "X-Mailer: PHP/" . phpversion();
mail($to, $s, $body, $headers);
}
You should always include all relevant code when asking a question. In this case, the print statement that is the center of your question. The print statement is probably the most crucial piece of information. The second most crucial piece of information is the error, which you also did not include. Next time, include both of those.
print $ids
should be a fairly hard statement to mess up, but it is possible. Possible reasons:
$ids
is undefined. Gives the warning undefined value in print
$ids
is out of scope. With use
strict
, gives fatal warning Global
variable $ids needs explicit package
name
, and otherwise the undefined
warning from above.print $ids $nIds
,
in which case perl thinks that $ids
is supposed to be a filehandle, and
you get an error such as print to
unopened filehandle
.Explanations
1: Should not happen. It might happen if you do something like this (assuming you are not using strict
):
my $var;
while (<>) {
$Var .= $_;
}
print $var;
Gives the warning for undefined value, because $Var
and $var
are two different variables.
2: Might happen, if you do something like this:
if ($something) {
my $var = "something happened!";
}
print $var;
my
declares the variable inside the current block. Outside the block, it is out of scope.
3: Simple enough, common mistake, easily fixed. Easier to spot with use warnings
.
4: Also a common mistake. There are a number of ways to correctly print two variables in the same print
statement:
print "$var1 $var2"; # concatenation inside a double quoted string
print $var1 . $var2; # concatenation
print $var1, $var2; # supplying print with a list of args
Lastly, some perl magic tips for you:
use strict;
use warnings;
# open with explicit direction '<', check the return value
# to make sure open succeeded. Using a lexical filehandle.
open my $fh, '<', 'file.txt' or die $!;
# read the whole file into an array and
# chomp all the lines at once
chomp(my @file = <$fh>);
close $fh;
my $ids = join(' ', @file);
my $nIds = scalar @file;
print "Number of lines: $nIds\n";
print "Text:\n$ids\n";
Reading the whole file into an array is suitable for small files only, otherwise it uses a lot of memory. Usually, line-by-line is preferred.
Variations:
print "@file"
is equivalent to
$ids = join(' ',@file); print $ids;
$#file
will return the last index
in @file
. Since arrays usually start at 0,
$#file + 1
is equivalent to scalar @file
. You can also do:
my $ids;
do {
local $/;
$ids = <$fh>;
}
By temporarily "turning off" $/
, the input record separator, i.e. newline, you will make <$fh>
return the entire file. What <$fh>
really does is read until it finds $/
, then return that string. Note that this will preserve the newlines in $ids
.
Line-by-line solution:
open my $fh, '<', 'file.txt' or die $!; # btw, $! contains the most recent error
my $ids;
while (<$fh>) {
chomp;
$ids .= "$_ "; # concatenate with string
}
my $nIds = $.; # $. is Current line number for the last filehandle accessed.

RewriteRule ^(.*)\.html$ $1.php%{QUERY_STRING} [L]
Put these two lines at the top of your .htaccess file. It will show .html in the URL for your .php pages.
RewriteEngine on
RewriteRule ^(.*)\.php$ $1.html%{QUERY_STRING} [L]

Try to add the following line in ~/.bashrc
export PYTHONPATH=/usr/local/lib/python2.7/site-packages:$PYTHONPATH
You can use exec
for that:

>>> exec(foo + " = 'something else'")
>>> print bar
something else

One thing that has worked for me with random npm install errors (where the package that errors out is different under different times (but same environment) is to use this:
npm cache clean
And then repeat the process. Then the process seems to go smoother and the real problem and error message will emerge, where you can fix it and then proceed.
This is based on experience of running npm install of a whole bunch of packages under a pretty bare Ubuntu installation inside a Docker instance. Sometimes there are build/make tools missing from the Ubuntu and the npm errors will not show the real problem until you clean the cache for some reason.
Although I've tried all the previous answers, only the following one worked out:

Here is a static class implementing Start(), Stop(), and IsStarted() for IISExpress. It is parametrized by hard-coded static properties and passes invocation information via the command-line arguments to IISExpress. It uses the Nuget package, MissingLinq.Linq2Management, which surprisingly provides information missing from System.Diagnostics.Process, specifically, the command-line arguments that can then be used to help disambiguate possible multiple instances of IISExpress processes, since I don't preserve the process Ids. I presume there is a way to accomplish the same thing with just System.Diagnostics.Process, but life is short. Enjoy.

I learned that you also can get this error by storing the source file in a folder named Java
Following up on @Bruno Bronosky and @mrteatime, I offer the suggestion that you just write your boolean return "backwards". This is what I mean:
foo()
{
if [ "$1" == "bar" ]; then
true; return
else
false; return
fi;
}
That eliminates the ugly two line requirement for every return statement.
The second method, Task.Run
, has been introduced in a later version of the .NET framework (in .NET 4.5).
However, the first method, Task.Factory.StartNew
, gives you the opportunity to define a lot of useful things about the thread you want to create, while Task.Run
doesn't provide this.
For instance, lets say that you want to create a long running task thread. If a thread of the thread pool is going to be used for this task, then this could be considered an abuse of the thread pool.
One thing you could do in order to avoid this would be to run the task in a separate thread. A newly created thread that would be dedicated to this task and would be destroyed once your task would have been completed. You cannot achieve this with the Task.Run
, while you can do so with the Task.Factory.StartNew
, like below:
Task.Factory.StartNew(..., TaskCreationOptions.LongRunning);
As it is stated here:
So, in the .NET Framework 4.5 Developer Preview, we’ve introduced the new Task.Run method. This in no way obsoletes Task.Factory.StartNew, but rather should simply be thought of as a quick way to use Task.Factory.StartNew without needing to specify a bunch of parameters. It’s a shortcut. In fact, Task.Run is actually implemented in terms of the same logic used for Task.Factory.StartNew, just passing in some default parameters. When you pass an Action to Task.Run:
Task.Run(someAction);
that’s exactly equivalent to:
Task.Factory.StartNew(someAction,
CancellationToken.None, TaskCreationOptions.DenyChildAttach, TaskScheduler.Default);
Try setting core.autocrlf value like this :
git config --global core.autocrlf true
form
If the name attribute is specified, the form controller is published onto the current scope under this name.
Alias: ngForm
In Angular, forms can be nested. This means that the outer form is valid when all of the child forms are valid as well. However, browsers do not allow nesting of elements, so Angular provides the ngForm directive which behaves identically to but can be nested. This allows you to have nested forms, which is very useful when using Angular validation directives in forms that are dynamically generated using the ngRepeat directive. Since you cannot dynamically generate the name attribute of input elements using interpolation, you have to wrap each set of repeated inputs in an ngForm directive and nest these in an outer form element.
CSS classes
ng-valid is set if the form is valid.
ng-invalid is set if the form is invalid.
ng-pristine is set if the form is pristine.
ng-dirty is set if the form is dirty.
ng-submitted is set if the form was submitted.
Keep in mind that ngAnimate can detect each of these classes when added and removed.
Submitting a form and preventing the default action
Since the role of forms in client-side Angular applications is different than in classical roundtrip apps, it is desirable for the browser not to translate the form submission into a full page reload that sends the data to the server. Instead some javascript logic should be triggered to handle the form submission in an application-specific way.
For this reason, Angular prevents the default action (form submission to the server) unless the element has an action attribute specified.
You can use one of the following two ways to specify what javascript method should be called when a form is submitted:
ngSubmit directive on the form element
ngClick directive on the first button or input field of type submit (input[type=submit])
To prevent double execution of the handler, use only one of the ngSubmit or ngClick directives.
This is because of the following form submission rules in the HTML specification:
If a form has only one input field then hitting enter in this field triggers form submit (ngSubmit)
if a form has 2+ input fields and no buttons or input[type=submit]
then hitting enter doesn't trigger submit
if a form has one or more input fields and one or more buttons or input[type=submit]
then hitting enter in any of the input fields will trigger the click handler on the first button or input[type=submit]
(ngClick) and a submit handler on the enclosing form (ngSubmit).
Any pending ngModelOptions changes will take place immediately when an enclosing form is submitted. Note that ngClick events will occur before the model is updated.
Use ngSubmit to have access to the updated model.
app.js:
angular.module('formExample', [])
.controller('FormController', ['$scope', function($scope) {
$scope.userType = 'guest';
}]);
Form:
<form name="myForm" ng-controller="FormController" class="my-form">
userType: <input name="input" ng-model="userType" required>
<span class="error" ng-show="myForm.input.$error.required">Required!</span>
userType = {{userType}}
myForm.input.$valid = {{myForm.input.$valid}}
myForm.input.$error = {{myForm.input.$error}}
myForm.$valid = {{myForm.$valid}}
myForm.$error.required = {{!!myForm.$error.required}}
</form>

Try running task manager to determine if your program is still running.
If it is running then stop it and run it again. the [Error] ld returned 1 exit status will not come back
