You are welcome :)
You can use the instanceof
operator for this. From MDN:
The instanceof operator tests whether the prototype property of a constructor appears anywhere in the prototype chain of an object.
If you don't know what prototypes and prototype chains are I highly recommend looking it up. Also here is a JS (TS works similar in this respect) example which might clarify the concept:
class Animal {_x000D_
name;_x000D_
_x000D_
constructor(name) {_x000D_
this.name = name;_x000D_
}_x000D_
}_x000D_
_x000D_
const animal = new Animal('fluffy');_x000D_
_x000D_
// true because Animal in on the prototype chain of animal_x000D_
console.log(animal instanceof Animal); // true_x000D_
// Proof that Animal is on the prototype chain_x000D_
console.log(Object.getPrototypeOf(animal) === Animal.prototype); // true_x000D_
_x000D_
// true because Object in on the prototype chain of animal_x000D_
console.log(animal instanceof Object); _x000D_
// Proof that Object is on the prototype chain_x000D_
console.log(Object.getPrototypeOf(Animal.prototype) === Object.prototype); // true_x000D_
_x000D_
console.log(animal instanceof Function); // false, Function not on prototype chain_x000D_
_x000D_
_x000D_
The prototype chain in this example is:
animal > Animal.prototype > Object.prototype
Based off this answer from Lucas Cerro I calculated the dimensions using the ratios in the Android docs, using the baseline in the answer. I hope this helps someone else coming to this post!
You can set imageview in XML file like this :
<ImageView
android:id="@+id/image1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="@drawable/imagep1" />
and you can define image view in android java file like :
ImageView imageView = (ImageView) findViewById(R.id.imageViewId);
and set Image with drawable like :
imageView.setImageResource(R.drawable.imageFileId);
and set image with your memory folder like :
File file = new File(SupportedClass.getString("pbg"));
if (file.exists()) {
BitmapFactory.Options options = new BitmapFactory.Options();
options.inPreferredConfig = Bitmap.Config.ARGB_8888;
Bitmap selectDrawable = BitmapFactory.decodeFile(file.getAbsolutePath(), options);
imageView.setImageBitmap(selectDrawable);
}
else
{
Toast.makeText(getApplicationContext(), "File not Exist", Toast.LENGTH_SHORT).show();
}
Copy the file "servlet-api.jar" from location YOUR_INSTILLATION_PATH\tomcat\lib\servlet-api.jar and Paste the file into your Java Directory YOUR_INSTILLATION_PATH\Java\jdk1.8.0_121\jre\lib\ext
this will work (tested).
let its required n bit then 2^n=(base)^digit and then take log and count no. for n
The JSON spec says you CAN escape forward slash, but you don't have to.
That is weird, everything looks fine, are you sure it does not work for you? Because this main
surely works for me, so I would look somewhere else for the source of your problem.
#include <QFile>
#include <QTextStream>
int main()
{
QString filename = "Data.txt";
QFile file(filename);
if (file.open(QIODevice::ReadWrite)) {
QTextStream stream(&file);
stream << "something" << endl;
}
}
The code you provided is also almost the same as the one provided in detailed description of QTextStream so I am pretty sure, that the problem is elsewhere :)
Also note, that the file is not called Data
but Data.txt
and should be created/located in the directory from which the program was run (not necessarily the one where the executable is located).
Exporting without default
means it's a "named export". You can have multiple named exports in a single file. So if you do this,
class Template {}
class AnotherTemplate {}
export { Template, AnotherTemplate }
then you have to import these exports using their exact names. So to use these components in another file you'd have to do,
import {Template, AnotherTemplate} from './components/templates'
Alternatively if you export as the default
export like this,
export default class Template {}
Then in another file you import the default export without using the {}
, like this,
import Template from './components/templates'
There can only be one default export per file. In React it's a convention to export one component from a file, and to export it is as the default export.
You're free to rename the default export as you import it,
import TheTemplate from './components/templates'
And you can import default and named exports at the same time,
import Template,{AnotherTemplate} from './components/templates'
Why don't you just use .to_frame if both have the same indexes?
>= v0.23
a.to_frame().join(b)
< v0.23
a.to_frame().join(b.to_frame())
I was facing same issue and got the error while uploading apk to Google play. I used ads in my app, and I was not even mentioned READ_PHONE_STATE permission in my manifest file. but yet I got this error. Then I change dependencies for ads in build.gradle file. and then it solved my issue. They solved this issue in 12.0.1.
compile 'com.google.android.gms:play-services-ads:12.0.1'
I had great trouble with this for devices that had vibration turned off in some manner, but we needed it to work regardless, because it is critical to our application functioning, and since it is just an integer to a documented method call, it will pass validation. So I have tried some sounds that were outside of the well documented ones here: TUNER88/iOSSystemSoundsLibrary
I have then stumbled upon 1352, which is working regardless of the silent switch or the settings on the device (Settings->vibrate on ring, vibrate on silent)
.
- (void)vibratePhone;
{
if([[UIDevice currentDevice].model isEqualToString:@"iPhone"])
{
AudioServicesPlaySystemSound (1352); //works ALWAYS as of this post
}
else
{
// Not an iPhone, so doesn't have vibrate
// play the less annoying tick noise or one of your own
AudioServicesPlayAlertSound (1105);
}
}
I've created one function which converts all the timezones into local time.
Requirements:
1. npm i moment-timezone
function utcToLocal(utcdateTime, tz) {
var zone = moment.tz(tz).format("Z") // Actual zone value e:g +5:30
var zoneValue = zone.replace(/[^0-9: ]/g, "") // Zone value without + - chars
var operator = zone && zone.split("") && zone.split("")[0] === "-" ? "-" : "+" // operator for addition subtraction
var localDateTime
var hours = zoneValue.split(":")[0]
var minutes = zoneValue.split(":")[1]
if (operator === "-") {
localDateTime = moment(utcdateTime).subtract(hours, "hours").subtract(minutes, "minutes").format("YYYY-MM-DD HH:mm:ss")
} else if (operator) {
localDateTime = moment(utcdateTime).add(hours, "hours").add(minutes, "minutes").format("YYYY-MM-DD HH:mm:ss")
} else {
localDateTime = "Invalid Timezone Operator"
}
return localDateTime
}
utcToLocal("2019-11-14 07:15:37", "Asia/Kolkata")
//Returns "2019-11-14 12:45:37"
Try using delegate instead of live as here:
$('#link-wrapper').delegate('a', 'click', function() {
// do something ..
}
you can use multiple attribute
<SELECT NAME="Testing" multiple>
<OPTION VALUE="1"> One
<OPTION VALUE="2"> Two
<OPTION VALUE="3"> Three
@echo off
Set filename=C:\Documents and Settings\All Users\Desktop\Dostips.cmd
For %%A in ("%filename%") do (
Set Folder=%%~dpA
Set Name=%%~nxA
)
echo.Folder is: %Folder%
echo.Name is: %Name%
But I can't take credit for this; Google found this at http://www.dostips.com/forum/viewtopic.php?f=3&t=409

"
to "import org.springframework.web.servlet.ModelAndView;
"...I am so glad to solve this problem:
HttpPost httppost = new HttpPost(postData);
CookieStore cookieStore = new BasicCookieStore();
BasicClientCookie cookie = new BasicClientCookie("JSESSIONID", getSessionId());

cookie.setPath("/");
cookieStore.addCookie(cookie);
client.setCookieStore(cookieStore);

So Easy!
I wanted a more permanent and quicker way. Because I tend to forget to add extra lines before writing my actual Update/Insert queries.
I did it by checking SET IMPLICIT_TRANSACTIONS check-box from Options. To navigate to Options Select Tools>Options>Query Execution>SQL Server>ANSI in your Microsoft SQL Server Management Studio.
Just make sure to execute commit
or rollback
after you are done executing your queries. Otherwise, the table you would have run the query will be locked for others.
I was looking for a solution for this for a long time and found most of the answers are not working or not suitable for my situation i also find most of the java script code for that they worked but only with the vertical scroll not with the horizontal scroll and also combination of header and rows doesn't match.
Finally i have found a solution with javascript here is the link bellow :-
scrollable horizontal and vertical grid view with fixed headers
Add just these two lines before the datetime property in your model
[DataType(DataType.Date)]
[DisplayFormat(DataFormatString = "{0:yyyy-MM-dd}", ApplyFormatInEditMode = true)]
and result will be :
Unfortunately renewing does not seem to work in my case. My Ad Hoc Distribution Profile is about to expire in 5 days. I got warnings about that on the iPhone and the Xcode Organizer shows a warning sign next to it as well.
In Apple's provisioning portal it was marked as inactive and there was a button to reactivate it. But still with the same expiry date, 5 days from now. Next, I added two more iPhones to it, yet, the changed profile still expires 5 days from now.
Finally, I deleted the profile in the provisioning portal and created a new one from scratch, using a different name, yet this new one still expires on April 13th, 5 days from now!
That is really frustrating! So I guess I have to wait until after it expires and create a new one then.
In case you are wondering if my developer subscription runs out, it is not. I just renewed it in February.
If you have used:
from datetime import datetime
Then simply write the code as:
date = datetime(int(year), int(month), 1)
But if you have used:
import datetime
then only you can write:
date = datetime.datetime(int(2005), int(5), 1)
The .git/config
file in a particular clone of a repository is local to that clone. Any settings placed there will only affect actions for that particular project.
(By default, git config
modifies .git/config
, not ~/.gitconfig
- only with --global
does it modify the latter.)
In my case I had couple of such errors:
The process cannot access the file 'C:\xxx\bin\Debug\netcoreapp3.1\yyy.dll'
because it is being used by another process. [C:\zzz.csproj]
I was able to see those errors only after adding -v parameter.
The solution was to shutdown the Visual Studio and run the command again.
Assuming you have referenced and correctly integrated your font to your site (presumably using an @font-face kit) it should be alright to just reference yours the way you do. Presumably it is like this so they have fall backs incase some browsers do not render the fonts correctly
The current answers contain a lot of hand-rolled or library code. This is not necessary.
Use JSON.parse('{"a":1}')
to create a plain object.
Use one of the standardized functions to set the prototype:
Object.assign(new Foo, { a: 1 })
Object.setPrototypeOf({ a: 1 }, Foo.prototype)
I think str_replace(array("\\r\\n", "\\r", "\\n"), " ", $string);
will work.
Try to check it's size with sizeof
if 0
no elements.
One has exactly space for 11 bytes, the other for exactly 11 characters. Some charsets such as Unicode variants may use more than one byte per char, therefore the 11 byte field might have space for less than 11 chars depending on the encoding.
See also http://www.joelonsoftware.com/articles/Unicode.html
Even if I want to return a business logic error as HTTP code there is no such acceptable HTTP error code for that errors rather than using HTTP 200 because it will misrepresent the actual error.
So, HTTP 200 will be good for business logic errors. But all errors which are covered by HTTP error codes should use them.
Basically HTTP 200 means what server correctly processes user request (in case of there is no seats on the plane it is no matter because user request was correctly processed, it can even return just a number of seats available on the plane, so there will be no business logic errors at all or that business logic can be on client side. Business logic error is an abstract meaning, but HTTP error is more definite).
It's called a 'constraint' on the generic parameter T. It means that T must be a reference type (a class) and that it must have a public default constructor.
With C++11, I'd prefer following to append vector b to a:
std::move(b.begin(), b.end(), std::back_inserter(a));
when a
and b
are not overlapped, and b
is not going to be used anymore.
This is std::move
from <algorithm>
, not the usual std::move
from <utility>
.
It would be easier to make suggestions if you provided example code and data.
Accessing the dictionary is unlikely to be a problem as that operation is O(1) on average, and O(N) amortized worst case. It's possible that the built-in hashing functions are experiencing collisions for your data. If you're having problems with has the built-in hashing function, you can provide your own.
Python's dictionary implementation reduces the average complexity of dictionary lookups to O(1) by requiring that key objects provide a "hash" function. Such a hash function takes the information in a key object and uses it to produce an integer, called a hash value. This hash value is then used to determine which "bucket" this (key, value) pair should be placed into.
You can overwrite the __hash__ method in your class to implement a custom hash function like this:
def __hash__(self):
return hash(str(self))
Depending on what your data actually looks like, you might be able to come up with a faster hash function that has fewer collisions than the standard function. However, this is unlikely. See the Python Wiki page on Dictionary Keys for more information.
I think this what you need, I mean when we want to show this toast, when there is only one activity in the stack and user pressing back from this last activity of the stack.
var exitOpened=false // Declare it globaly
and in onBackPressed
method change it like:
override fun onBackPressed() {
if (isTaskRoot && !exitOpened)
{
exitOpened=true
toast("Please press back again to exit")
return
}
super.onBackPressed()
}
Here, isTaskRoot
will return true if the current activity is the root activity(first activity) of the stack and false if it is not.
You can check the official documentation here
The form should map the species->id value automatically to the selected entity select field. For example if your have a Breed entity that has a OnetoOne relationship with a Species entity in a join table called 'breed_species':
class Breed{
private $species;
/**
* @ORM\OneToOne(targetEntity="BreedSpecies", mappedBy="breed")
*/
private $breedSpecies;
public function getSpecies(){
return $breedSpecies->getSpecies();
}
private function getBreedSpecies(){
return $this->$breedSpecies;
}
}
The field 'species' in the form class should pick up the species->id value from the 'species' attribute object in the Breed class passed to the form.
Alternatively, you can explicitly set the value by explicitly passing the species entity into the form using SetData():
$breedForm = $this->createForm( new BreedForm(), $breed );
$species = $breed->getBreedSpecies()->getSpecies();
$breedForm->get('species')->setData( $species );
return $this->render( 'AcmeBundle:Computer:edit.html.twig'
, array( 'breed' => $breed
, 'breedForm' => $breedForm->createView()
)
);
I have seen exactly the same error, also with IE11. In my case the issue occurred when user clicked <button>
element, which was inside <form>
tags.
The issue was remedied, by placing the <button>
outside of <form>
tags.
In my case i did the following and worked for me
To check if element is visible we need to use element.isDisplayed();
But if we need to check for presence of element anywhere in Dom we can use following method
public boolean isElementPresentCheckUsingJavaScriptExecutor(WebElement element) {
JavascriptExecutor jse=(JavascriptExecutor) driver;
try {
Object obj = jse.execute("return typeof(arguments[0]) != 'undefined' && arguments[0] != null;",
element);
if (obj.toString().contains("true")) {
System.out.println("isElementPresentCheckUsingJavaScriptExecutor: SUCCESS");
return true;
} else {
System.out.println("isElementPresentCheckUsingJavaScriptExecutor: FAIL");
}
} catch (NoSuchElementException e) {
System.out.println("isElementPresentCheckUsingJavaScriptExecutor: FAIL");
}
return false;
}
There are two ways to customize fonts :
!!! my custom font in assets/fonts/iran_sans.ttf
Way 1 : Refrection Typeface.class ||| best way
call FontsOverride.setDefaultFont() in class extends Application, This code will cause all software fonts to be changed, even Toasts fonts
AppController.java
public class AppController extends Application {
@Override
public void onCreate() {
super.onCreate();
//Initial Font
FontsOverride.setDefaultFont(getApplicationContext(), "MONOSPACE", "fonts/iran_sans.ttf");
}
}
FontsOverride.java
public class FontsOverride {
public static void setDefaultFont(Context context, String staticTypefaceFieldName, String fontAssetName) {
final Typeface regular = Typeface.createFromAsset(context.getAssets(), fontAssetName);
replaceFont(staticTypefaceFieldName, regular);
}
private static void replaceFont(String staticTypefaceFieldName, final Typeface newTypeface) {
try {
final Field staticField = Typeface.class.getDeclaredField(staticTypefaceFieldName);
staticField.setAccessible(true);
staticField.set(null, newTypeface);
} catch (NoSuchFieldException e) {
e.printStackTrace();
} catch (IllegalAccessException e) {
e.printStackTrace();
}
}
}
Way 2: use setTypeface
for special view just call setTypeface() to change font.
CTextView.java
public class CTextView extends TextView {
public CTextView(Context context) {
super(context);
init(context,null);
}
public CTextView(Context context, @Nullable AttributeSet attrs) {
super(context, attrs);
init(context,attrs);
}
public CTextView(Context context, @Nullable AttributeSet attrs, int defStyleAttr) {
super(context, attrs, defStyleAttr);
init(context,attrs);
}
@RequiresApi(api = Build.VERSION_CODES.LOLLIPOP)
public CTextView(Context context, @Nullable AttributeSet attrs, int defStyleAttr, int defStyleRes) {
super(context, attrs, defStyleAttr, defStyleRes);
init(context,attrs);
}
public void init(Context context, @Nullable AttributeSet attrs) {
if (isInEditMode())
return;
// use setTypeface for change font this view
setTypeface(FontUtils.getTypeface("fonts/iran_sans.ttf"));
}
}
FontUtils.java
public class FontUtils {
private static Hashtable<String, Typeface> fontCache = new Hashtable<>();
public static Typeface getTypeface(String fontName) {
Typeface tf = fontCache.get(fontName);
if (tf == null) {
try {
tf = Typeface.createFromAsset(AppController.getInstance().getApplicationContext().getAssets(), fontName);
} catch (Exception e) {
e.printStackTrace();
return null;
}
fontCache.put(fontName, tf);
}
return tf;
}
}
If you're on some Linux system, imagemagick is perfect. I.e
convert somefile.png somefile.svg
This works with heaps of different formats.
For other media such as videos and audio use (ffmpeg) I know you clearly stated png to svg, however; It's still media related.
ffmpeg -i somefile.mp3 somefile.ogg
Just a tip for if you wish to go through lots of files; a loop using basic shell tricks..
for f in *.jpg; do convert $f ${f%jpg}png; done
That removes the jpg and adds png which tells convert what you want.
Alright, I think I got what you're asking for. Try this
if(window.top==window) {
// You're not in a frame, so you reload the site.
window.setTimeout('location.reload()', 3000); //Reloads after three seconds
}
else {
//You're inside a frame, so you stop reloading.
}
If it is once, then just do
$('#div-id').triggerevent(function(){
$('#div-id').html(newContent);
});
If it is periodically
function updateDiv(){
//Get new content through Ajax
...
$('#div-id').html(newContent);
}
setInterval(updateDiv, 5000); // That's five seconds
So, every five seconds the div #div-id content will refresh. Better than refreshing the whole page.
xlim
and ylim
don't cut it here. You need to use expand_limits
, scale_x_continuous
, and scale_y_continuous
. Try:
df <- data.frame(x = 1:5, y = 1:5)
p <- ggplot(df, aes(x, y)) + geom_point()
p <- p + expand_limits(x = 0, y = 0)
p # not what you are looking for
p + scale_x_continuous(expand = c(0, 0)) + scale_y_continuous(expand = c(0, 0))
You may need to adjust things a little to make sure points are not getting cut off (see, for example, the point at x = 5
and y = 5
.
Policykit is a system daemon and policykit authentication agent is used to verify identity of the user before executing actions. The messages logged in /var/log/secure
show that an authentication agent is registered when user logs in and it gets unregistered when user logs out. These messages are harmless and can be safely ignored.
pandas now has a read_sql
function. You definitely want to use that instead.
I can't help you with SQLAlchemy -- I always use pyodbc, MySQLdb, or psychopg2 as needed. But when doing so, a function as simple as the one below tends to suit my needs:
import decimal
import pydobc
import numpy as np
import pandas
cnn, cur = myConnectToDBfunction()
cmd = "SELECT * FROM myTable"
cur.execute(cmd)
dataframe = __processCursor(cur, dataframe=True)
def __processCursor(cur, dataframe=False, index=None):
'''
Processes a database cursor with data on it into either
a structured numpy array or a pandas dataframe.
input:
cur - a pyodbc cursor that has just received data
dataframe - bool. if false, a numpy record array is returned
if true, return a pandas dataframe
index - list of column(s) to use as index in a pandas dataframe
'''
datatypes = []
colinfo = cur.description
for col in colinfo:
if col[1] == unicode:
datatypes.append((col[0], 'U%d' % col[3]))
elif col[1] == str:
datatypes.append((col[0], 'S%d' % col[3]))
elif col[1] in [float, decimal.Decimal]:
datatypes.append((col[0], 'f4'))
elif col[1] == datetime.datetime:
datatypes.append((col[0], 'O4'))
elif col[1] == int:
datatypes.append((col[0], 'i4'))
data = []
for row in cur:
data.append(tuple(row))
array = np.array(data, dtype=datatypes)
if dataframe:
output = pandas.DataFrame.from_records(array)
if index is not None:
output = output.set_index(index)
else:
output = array
return output
Like all of us, you are another victim of asynchronous I/O. With asynchronous calls, if you loop around a lot of files, Node.js will start to open a file descriptor for each file to read and then will wait for action until you close it.
File descriptor remains open until resource is available on your server to read it. Even if your files are small and reading or updating is fast, it takes some time, but in the same time your loop don't stop to open new files descriptor. So if you have too many files, the limit will be soon reached and you get a beautiful EMFILE.
There is one solution, creating a queue to avoid this effect.
Thanks to people who wrote Async, there is a very useful function for that. There is a method called Async.queue, you create a new queue with a limit and then add filenames to the queue.
Note: If you have to open many files, it would be a good idea to store which files are currently open and don't reopen them infinitely.
const fs = require('fs')
const async = require("async")
var q = async.queue(function(task, callback) {
console.log(task.filename);
fs.readFile(task.filename,"utf-8",function (err, data_read) {
callback(err,task.filename,data_read);
}
);
}, 4);
var files = [1,2,3,4,5,6,7,8,9,10]
for (var file in files) {
q.push({filename:file+".txt"}, function (err,filename,res) {
console.log(filename + " read");
});
}
You can see that each file is added to the queue (console.log filename), but only when the current queue is under the limit you set previously.
async.queue get information about availability of the queue through a callback, this callback is called only when data file is read and any action you have to do is achieved. (see fileRead method)
So you cannot be overwhelmed by files descriptor.

When the button has a background from the drawable, we can add ripple effect to the foreground parameter.. Check below code its working for my button with a different background
<Button
android:layout_width="wrap_content"
android:layout_height="40dp"
android:gravity="center"
android:layout_centerHorizontal="true"
android:background="@drawable/shape_login_button"
android:foreground="?attr/selectableItemBackgroundBorderless"
android:clickable="true"
android:text="@string/action_button_login"
/>
Add below parameter for the ripple effect
android:foreground="?attr/selectableItemBackgroundBorderless"
android:clickable="true"
For reference refer below link https://jascode.wordpress.com/2017/11/11/how-to-add-ripple-effect-to-an-android-app/
'b' should be in capital letter in document.getElementById
modified code jsfiddle
function test()

Given what you've tried and the error messages, I'd say this was more to do with the exact cipher algorithm used rather than the TLS/SSL version. Are you using a non-Sun JRE by any chance, or a different vendor's security implementation? Try a different JRE/OS to test your server if you can. Failing that you might just be able to see what's going on with Wireshark (with a filter of 'tcp.port == 443').
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>

Below, code snippet, will help you in understanding the mutex-lock-unlock concept. Attempt dry-run on the code. (further by varying the wait-time and process-time, you can build you understanding).

void in_progress_feedback(int);
int global = 0;
pthread_mutex_t mutex;
void *compute(void *arg) {
pthread_t ptid = pthread_self();

int i;
int lock_ret = 1;
do{
lock_ret = pthread_mutex_trylock(&mutex);
if(lock_ret){

You could try using this tool which automatically removes the Team Foundation Bindings from a project. http://www.softpedia.com/get/Programming/Other-Programming-Files/Team-Foundation-Binding-Remover.shtml
Before trying to delete/rename any file, you must ensure that all the readers or writers (for ex: BufferedReader
/InputStreamReader
/BufferedWriter
) are properly closed.
When you try to read/write your data from/to a file, the file is held by the process and not released until the program execution completes. If you want to perform the delete/rename operations before the program ends, then you must use the close()
method that comes with the java.io.*
classes.
Just loop...
foreach(var table in DataSet1.Tables) {
foreach(var col in table.Columns) {
...
}
foreach(var row in table.Rows) {
object[] values = row.ItemArray;
...
}
}
I got similar error while working with datatable. What happens is when you use *ngFor inside another *ngFor datatable throw this error as it interepts angular change cycle. SO instead of using datatable inside datatable use one regular table or replace mf.data with the array name. This works fine.
#compare 1st half with reversed second half
# i.e. 'abba' -> 'ab' == 'ba'[::-1]
def is_palindrome( s ):
return True if len( s ) < 2 else s[ :len( s ) // 2 ] == s[ -( len( s ) // 2 ):][::-1]
Looks like you might have until the end of 2013 before they officially close it down. http://groups.google.com/group/google-ajax-search-api/browse_thread/thread/6aaa1b3529620610/d70f8eec3684e431?lnk=gst&q=news+api#d70f8eec3684e431
Also, it sounds like they are building a replacement... but it's going to cost you.
I'd say, go to a different service. I think bing has a news API.

Assuming the image data is already in the format you want, you don't need image ImageIO
at all - you just need to write the data to the file:
// Note preferred way of declaring an array variable
byte[] data = Base64.decodeBase64(crntImage);
try (OutputStream stream = new FileOutputStream("c:/decode/abc.bmp")) {
stream.write(data);
}
(I'm assuming you're using Java 7 here - if not, you'll need to write a manual try/finally statement to close the stream.)
If the image data isn't in the format you want, you'll need to give more details.
You can write a try - catch block around the line you want to have ignored.
Like in the example code of yours. If you just continue your code below the closing bracket of the catch block everythings fine.

I found a way to cover the shadow with ":after", here is my code:
#div:after {
content:"";
position:absolute;
width:5px;
background:#fff;
height:38px;
top:1px;
right:-5px;
}
memory mapping is not only used to map files into memory but is also a tool to request RAM from kernel. These are those inode 0 entries - your stack, heap, bss segments and more
Spaces are used for separating Arguments. In your case C:\Program becomes argument. If your file path contains spaces then add Double quotation marks. Then cmd will recognize it as single argument.
Use this.
app.use((req,res, next)=>{
res.setHeader('Access-Control-Allow-Origin',"http://localhost:3000");
res.setHeader('Access-Control-Allow-Headers',"*");
res.header('Access-Control-Allow-Credentials', true);
next();
});
It's a shortening for this:
notification.defaults = notification.defaults | Notification.DEFAULT_SOUND;
And |
is a bit-wise OR.
The command to just stream it to a new container (mp4) needed by some applications like Adobe Premiere Pro without encoding (fast) is:
ffmpeg -i input.mov -qscale 0 output.mp4
Alternative as mentioned in the comments, which re-encodes with best quaility (-qscale 0
):
ffmpeg -i input.mov -q:v 0 output.mp4
I was facing similar issue on Linux mint what I did was found out Debian version using,
$ cat /etc/debian_version

then replaced Debian version in
$ sudo vi /etc/apt/sources.list.d/additional-repositories.list

The widely-upvoted answer is fine, I've used it for quite some time in the form of this bat file:

It requires access on the path to 7zip, and must be run in a folder alongside the JDK of your choice (it'll find it because of the *.exe up here).
Works on 8u144, and I guess it worked from the 8u20 thing.
Sometimes .concat() is better than .push() since .concat() returns the new array whereas .push() returns the length of the array.
Therefore, if you are setting a variable equal to the result, use .concat().
items = [{'id': 1}, {'id': 2}, {'id': 3}, {'id': 4}];
newArray = items.push({'id':5})
In this case, newArray will return 5 (the length of the array).
newArray = items.concat({'id': 5})
However, here newArray will return [{'id': 1}, {'id': 2}, {'id': 3}, {'id': 4}, {'id': 5}].
If you want the onload method to take parameters, you can do something similar to this:
window.onload = function() {
yourFunction(param1, param2);
};
This binds onload to an anonymous function, that when invoked, will run your desired function, with whatever parameters you give it. And, of course, you can run more than one function from inside the anonymous function.
you can use len(arr)
as suggested in previous answers to get the length of the array. In case you want the dimensions of a 2D array you could use arr.shape
returns height and width
grep
matches, grep -v
does the inverse. If you need to "match A but not B" you usually use pipes:
grep "${PATT}" file | grep -v "${NOTPATT}"
Start->Search->For Files and Folders->All Files and Folders
type "my.cnf" and hit search.
Here is an example code
import unicodedata
raw_text = u"here $%6757 dfgdfg"
convert_text = unicodedata.normalize('NFKD', raw_text).encode('ascii','ignore')
You could modify the project configuration temporarily to save only the last 1 build, reload the configuration (which should trash the old builds), then change the configuration setting again to your desired value.
jQuery attribute val() should do the job.
You can do $('#YourTextareaID').click(function(e) { e.target.value = ''; })
.
Debug.Print
outputs to the "Immediate" window.
Also, you can simply type ?
and then a statement directly into the immediate window (and then press Enter) and have the output appear right below, like this:
This can be very handy to quickly output the property of an object...
? myWidget.name
...to set the property of an object...
myWidget.name = "thingy"
...or to even execute a function or line of code, while in debugging mode:
Sheet1.MyFunction()
Here is code that will upload multiple images at once, into a specific folder!
The HTML:
<form method="post" enctype="multipart/form-data" id="image_upload_form" action="submit_image.php">
<input type="file" name="images" id="images" multiple accept="image/x-png, image/gif, image/jpeg, image/jpg" />
<button type="submit" id="btn">Upload Files!</button>
</form>
<div id="response"></div>
<ul id="image-list">
</ul>
The PHP:
<?php
$errors = $_FILES["images"]["error"];
foreach ($errors as $key => $error) {
if ($error == UPLOAD_ERR_OK) {
$name = $_FILES["images"]["name"][$key];
//$ext = pathinfo($name, PATHINFO_EXTENSION);
$name = explode("_", $name);
$imagename='';
foreach($name as $letter){
$imagename .= $letter;
}
move_uploaded_file( $_FILES["images"]["tmp_name"][$key], "images/uploads/" . $imagename);
}
}
echo "<h2>Successfully Uploaded Images</h2>";
And finally, the JavaSCript/Ajax:
(function () {
var input = document.getElementById("images"),
formdata = false;
function showUploadedItem (source) {
var list = document.getElementById("image-list"),
li = document.createElement("li"),
img = document.createElement("img");
img.src = source;
li.appendChild(img);
list.appendChild(li);
}
if (window.FormData) {
formdata = new FormData();
document.getElementById("btn").style.display = "none";
}
input.addEventListener("change", function (evt) {
document.getElementById("response").innerHTML = "Uploading . . ."
var i = 0, len = this.files.length, img, reader, file;
for ( ; i < len; i++ ) {
file = this.files[i];
if (!!file.type.match(/image.*/)) {
if ( window.FileReader ) {
reader = new FileReader();
reader.onloadend = function (e) {
showUploadedItem(e.target.result, file.fileName);
};
reader.readAsDataURL(file);
}
if (formdata) {
formdata.append("images[]", file);
}
}
}
if (formdata) {
$.ajax({
url: "submit_image.php",
type: "POST",
data: formdata,
processData: false,
contentType: false,
success: function (res) {
document.getElementById("response").innerHTML = res;

});
}
}, false);
}());
Hope this helps
Either use an Allias in the table like T and use T.ID, or use just the column name.
declare @TEMP table (ID int, Name varchar(max))
insert into @temp SELECT ID, Name FROM Table
SELECT * FROM @TEMP
WHERE ID = 1
In my case, for both Debug and Release, the solution was to clean then rebuild entire solution.
Edit: true in my case also (VS2017) step1: clean the project. step2: change configuration mode(from debug to release or vice versa). step3: clean the project. step4: build in the required configuration mode.
PS: to change config mode, find config settings under build menu
if you know the file name, but don't know the file extention you can use this function:
public function showImage($name)
{
$types = [
'gif'=> 'image/gif',
'png'=> 'image/png',
'jpeg'=> 'image/jpeg',
'jpg'=> 'image/jpeg',
];
$root_path = '/var/www/my_app'; //use your framework to get this properly ..
foreach($types as $type=>$meta){
if(file_exists($root_path .'/uploads/'.$name .'.'. $type)){
header('Content-type: ' . $meta);
readfile($root_path .'/uploads/'.$name .'.'. $type);
return;
}
}
}
Note: the correct content-type for JPG files is image/jpeg
.
Running scripts can be terminated from the Task Manager.
However, scripts that perpetually focus program windows using .AppActivate may make it very difficult to get to the task manager -i.e you and the script will be fighting for control. Hence i recommend writing a script (which i call self destruct for obvious reasons) and make a keyboard shortcut key to activate the script.
Self destruct script:
Option Explicit
Dim WshShell
Set WshShell = WScript.CreateObject("WScript.Shell")
WshShell.Run "taskkill /f /im Cscript.exe", , True
WshShell.Run "taskkill /f /im wscript.exe", , True
Keyboard shortcut: rightclick on the script icon, select create shortcut, rightclick on script shortcut icon, select properties, click in shortcutkey and make your own.
type your shortcut key and all scripts end. Cheers
A one-liner (no essential difference to the answers above though):

Here is a one liner linq version of the accepted answer:
Enumerable.Range(0, reader.FieldCount).Any(i => reader.GetName(i) == "COLUMN_NAME_GOES_HERE")
LR is link register used to hold the return address for a function call.
SP is stack pointer. The stack is generally used to hold "automatic" variables and context/parameters across function calls. Conceptually you can think of the "stack" as a place where you "pile" your data. You keep "stacking" one piece of data over the other and the stack pointer tells you how "high" your "stack" of data is. You can remove data from the "top" of the "stack" and make it shorter.
From the ARM architecture reference:
SP, the Stack Pointer
Register R13 is used as a pointer to the active stack.
In Thumb code, most instructions cannot access SP. The only instructions that can access SP are those designed to use SP as a stack pointer. The use of SP for any purpose other than as a stack pointer is deprecated. Note Using SP for any purpose other than as a stack pointer is likely to break the requirements of operating systems, debuggers, and other software systems, causing them to malfunction.
LR, the Link Register
Register R14 is used to store the return address from a subroutine. At other times, LR can be used for other purposes.
When a BL or BLX instruction performs a subroutine call, LR is set to the subroutine return address. To perform a subroutine return, copy LR back to the program counter. This is typically done in one of two ways, after entering the subroutine with a BL or BLX instruction:
• Return with a BX LR instruction.
• On subroutine entry, store LR to the stack with an instruction of the form: PUSH {,LR} and use a matching instruction to return: POP {,PC} ...
Restartable mode (/Z) has to do with a partially-copied file. With this option, should the copy be interrupted while any particular file is partially copied, the next execution of robocopy can pick up where it left off rather than re-copying the entire file.
That option could be useful when copying very large files over a potentially unstable connection.
Backup mode (/B) has to do with how robocopy reads files from the source system. It allows the copying of files on which you might otherwise get an access denied error on either the file itself or while trying to copy the file's attributes/permissions. You do need to be running in an Administrator context or otherwise have backup rights to use this flag.
JAVA HOME
is used for setting up the environment variable for JAVA. It means that you are providing a path for compiling a JAVA program and also running the same. So, if you do not set the JAVA HOME( PATH ) and try to run a java or any dependent program in the command prompt.
You will deal with an error as
javac : not recognized as internal or external command
.
Now to set this, Just open your Java jdk then open bin folder then copy the PATH of that bin folder.
Now, go to My computer right click on it----> select properties-----> select Advanced system settings----->Click on Environment Variables------>select New----->give a name in the text box Variable Name and then paste the path in Value.
That's All!!
Generally speaking, using setState
inside useEffect
will create an infinite loop that most likely you don't want to cause. There are a couple of exceptions to that rule which I will get into later.
useEffect
is called after each render and when setState
is used inside of it, it will cause the component to re-render which will call useEffect
and so on and so on.
One of the popular cases that using useState
inside of useEffect
will not cause an infinite loop is when you pass an empty array as a second argument to useEffect
like useEffect(() => {....}, [])
which means that the effect function should be called once: after the first mount/render only. This is used widely when you're doing data fetching in a component and you want to save the request data in the component's state.
I do not understand what this is unclear
Properties are members that provide a flexible mechanism to read, write, or compute the values of private fields. Properties can be used as though they are public data members, but they are actually special methods called accessors. This enables data to be accessed easily while still providing the safety and flexibility of methods.
In this example, the class TimePeriod stores a time period. Internally the class stores the time in seconds, but a property called Hours is provided that allows a client to specify a time in hours. The accessors for the Hours property perform the conversion between hours and seconds.
Example
class TimePeriod
{
private double seconds;
public double Hours
{
get { return seconds / 3600; }
set { seconds = value * 3600; }
}
}
class Program
{
static void Main()
{
TimePeriod t = new TimePeriod();
// Assigning the Hours property causes the 'set' accessor to be called.
t.Hours = 24;
// Evaluating the Hours property causes the 'get' accessor to be called.
System.Console.WriteLine("Time in hours: " + t.Hours);
}
}
Properties Overview
Properties enable a class to expose a public way of getting and setting values, while hiding implementation or verification code.
A get property accessor is used to return the property value, and a set accessor is used to assign a new value. These accessors can have different access levels.
The value keyword is used to define the value being assigned by the set indexer.
Properties that do not implement a set method are read only.

In short, place black behind the image, and lower the opactiy. You can do this by wrapping the image within a div, and then lowering the opacity of the image.
For example:
<!DOCTYPE html>
<style>
.img-wrap {
background: black;
display: inline-block;
line-height: 0;
}
.img-wrap > img {
opacity: 0.8;
}
</style>
<div class="img-wrap">
<img src="http://mikecane.files.wordpress.com/2007/03/kitten.jpg" />
</div>
Here is a JSFiddle.
If you really want to create an array rather than a list use either
String[] names = ["lucas", "Fred", "Mary"]
or
def names = ["lucas", "Fred", "Mary"].toArray()
/*
If your delimiters are slash-based, escape it:
\/*
*
means "0 or more of the previous repeatable pattern", which can be a single character, a character class or a group.
You can use:
grep -l Dansk * | xargs grep -l Norsk | xargs grep -l Svenska
If you want also to find in hidden files:
grep -l Dansk .* | xargs grep -l Norsk | xargs grep -l Svenska
Just to add to how to use map files. I use chrome for ubuntu and if I go to sources and click on a file, if there is a map file a message comes up telling me that I can view the original file and how to do it.
For the Angular files that I worked with today I click
Ctrl-P and a list of original files comes up in a small window.
I can then browse through the list to view the file that I would like to inspect and check where the issue might be.
It probably just asks the operating system provided function, rather than its own algorithm.
As other comments says, use hashlib or write your own hash function.
I think this should work:
#include <time.h>
clock_t start = clock(), diff;
ProcessIntenseFunction();
diff = clock() - start;
int msec = diff * 1000 / CLOCKS_PER_SEC;
printf("Time taken %d seconds %d milliseconds", msec/1000, msec%1000);
Use casting of types:
int main() {
int a;
float b, c, d;
a = 750;
b = a / (float)350;
c = 750;
d = c / (float)350;
printf("%.2f %.2f", b, d);
// output: 2.14 2.14
}
This is another way to solve that:
int main() {
int a;
float b, c, d;
a = 750;
b = a / 350.0; //if you use 'a / 350' here,
//then it is a division of integers,
//so the result will be an integer
c = 750;
d = c / 350;
printf("%.2f %.2f", b, d);
// output: 2.14 2.14
}
However, in both cases you are telling the compiler that 350 is a float, and not an integer. Consequently, the result of the division will be a float, and not an integer.
When using Docker for Mac Application, it appears that the containers are stored within the VM located at:
~/Library/Containers/com.docker.docker/Data/com.docker.driver.amd64-linux/Docker.qcow2
UPDATE (Courtesy of mmorin):
As of Jan 15 2019 it seems there is only this file:
~/Library/Containers/com.docker.docker/Data/vms/0/Docker.raw
that contains the Docker Disk and all the images and containers within it.
The new html5 technology – fullscreen API gives us an easy way to present a web page content in full-screen mode. We are about to give you detailed information about the fullscreen mode. Just try to imagine about all possible advantages which you can get using this technology – full-screen photo albums, videos, and even games.
But before we describe this new technology, I have to note that this technology is experimental, and supported by all major Browsers.
You can find the full tutorial here : http://www.css-jquery-design.com/2013/11/javascript-jquery-fullscreen-browser-window-html5-technology/
Here is working Demo : http://demo.web3designs.com/javascript-jquery-fullscreen-browser-window-html5-technology.htm
Or in your SQL query wrap that field with IsNull or Coalesce (SQL Server).
Either way works, I like to put that logic in the query so the report has to do less.
New versions of excel have made old answers obsolete. It took a long time to make this, but it does a pretty good job. Note that the maximum image size is limited and the aspect ratio is ever so slightly off, as I was not able to perfectly optimize the reshaping math. Note that I've named one of my worksheets wsTMP, you can replace it with Sheet1 or the like. Takes about 1 second to print the screenshot to target path.

IIF
is not a standard SQL construct, but if it's supported by your database, you can achieve a more elegant statement producing the same result:
SELECT JobId, JobName,
COUNT(IIF (Priority=1, 1, NULL)) AS Priority1,
COUNT(IIF (Priority=2, 1, NULL)) AS Priority2,
COUNT(IIF (Priority=3, 1, NULL)) AS Priority3,
COUNT(IIF (Priority=4, 1, NULL)) AS Priority4,
COUNT(IIF (Priority=5, 1, NULL)) AS Priority5
FROM TableName
GROUP BY JobId, JobName
Perhaps something like this for the first problem, you can simply access the columns by their names:
>>> df = pd.DataFrame(np.random.rand(4,5), columns = list('abcde'))
>>> df[df['c']>.5][['b','e']]
b e
1 0.071146 0.132145
2 0.495152 0.420219
For the second problem:
>>> df[df['c']>.5][['b','e']].values
array([[ 0.07114556, 0.13214495],
[ 0.49515157, 0.42021946]])
Wouldn't
(int) Math.Min(Int32.MaxValue, longValue)
be the correct way, mathematically speaking?
You can also propagate your static pain with lambdas, so the whole thing looks readable:
s.filter(a -> propagate(a::isActive))
propagate
here receives java.util.concurrent.Callable
as a parameter and converts any exception caught during the call into RuntimeException
. There is a similar conversion method Throwables#propagate(Throwable) in Guava.
This method seems being essential for lambda method chaining, so I hope one day it will be added to one of the popular libs or this propagating behavior would be by default.
public class PropagateExceptionsSample {
// a simplified version of Throwables#propagate
public static RuntimeException runtime(Throwable e) {
if (e instanceof RuntimeException) {
return (RuntimeException)e;
}
return new RuntimeException(e);
}
// this is a new one, n/a in public libs
// Callable just suits as a functional interface in JDK throwing Exception
public static <V> V propagate(Callable<V> callable){
try {
return callable.call();
} catch (Exception e) {
throw runtime(e);
}
}
public static void main(String[] args) {
class Account{
String name;
Account(String name) { this.name = name;}
public boolean isActive() throws IOException {
return name.startsWith("a");
}
}
List<Account> accounts = new ArrayList<>(Arrays.asList(new Account("andrey"), new Account("angela"), new Account("pamela")));
Stream<Account> s = accounts.stream();
s
.filter(a -> propagate(a::isActive))
.map(a -> a.name)
.forEach(System.out::println);
}
}
If you don't have media, doing a dir /s vs_ultimate.exe
from the root prompt will find it. Mine was in C:\ProgramData\Package Cache\{[guid]}
. Once I navigated there and ran vs_ultimate.exe
with the /uninstall
and /force
flags, the uninstaller ran
I opened the program "Command Prompt"
with as administrator and search run "dir /s vs_ultimate.exe"
in ProgramData folder and find path to vs_ultimate.exe
file.
Then I changed my working directory to that path and ran vs_ultimate.exe /uninstall /force
.
Finally its done.
You can use a Union.
This will return the results of the queries in separate rows.
First you must make sure that both queries return identical columns.
Then you can do :
SELECT tableA.Id, tableA.Name, [tableB].Username AS Owner, [tableB].ImageUrl, [tableB].CompanyImageUrl, COUNT(tableD.UserId) AS Number
FROM tableD
RIGHT OUTER JOIN [tableB]
INNER JOIN tableA ON [tableB].Id = tableA.Owner ON tableD.tableAId = tableA.Id
GROUP BY tableA.Name, [tableB].Username, [tableB].ImageUrl, [tableB].CompanyImageUrl
UNION
SELECT tableA.Id, tableA.Name, '' AS Owner, '' AS ImageUrl, '' AS CompanyImageUrl, COUNT([tableC].Id) AS Number
FROM
[tableC]
RIGHT OUTER JOIN tableA ON [tableC].tableAId = tableA.Id GROUP BY tableA.Id, tableA.Name
As has been mentioned, both queries return quite different data. You would probably only want to do this if both queries return data that could be considered similar.
SO
You can use a Join
If there is some data that is shared between the two queries. This will put the results of both queries into a single row joined by the id, which is probably more what you want to be doing here...
You could do :
SELECT tableA.Id, tableA.Name, [tableB].Username AS Owner, [tableB].ImageUrl, [tableB].CompanyImageUrl, COUNT(tableD.UserId) AS NumberOfUsers, query2.NumberOfPlans
FROM tableD
RIGHT OUTER JOIN [tableB]
INNER JOIN tableA ON [tableB].Id = tableA.Owner ON tableD.tableAId = tableA.Id
INNER JOIN
(SELECT tableA.Id, COUNT([tableC].Id) AS NumberOfPlans
FROM [tableC]
RIGHT OUTER JOIN tableA ON [tableC].tableAId = tableA.Id
GROUP BY tableA.Id, tableA.Name) AS query2
ON query2.Id = tableA.Id
GROUP BY tableA.Name, [tableB].Username, [tableB].ImageUrl, [tableB].CompanyImageUrl

Frequently we deal with other fellow java programmers work which create these Stored Procedure. and we do not want to mess around with it. but there is possibility you get the result set where these exec sample return 0 (almost Stored procedure call returning zero).
check this sample :
public void generateINOUT(String USER, int DPTID){
try {
conUrl = JdbcUrls + dbServers +";databaseName="+ dbSrcNames+";instance=MSSQLSERVER";
con = DriverManager.getConnection(conUrl,dbUserNames,dbPasswords);

con.setAutoCommit(false);
Statement st = con.createStatement();
st.executeUpdate("DECLARE @RC int\n" +

"DECLARE @pEndDateTime datetime\n" +
"EXECUTE [AccessManager].[dbo].[SP_GenerateInOutDetailReportSimple] \n" +
""+USER +

ResultSet rs = st.getGeneratedKeys();
while (rs.next()){
String userID = rs.getString("UserID");
Timestamp timeIN = rs.getTimestamp("timeIN");
Timestamp timeOUT = rs.getTimestamp ("timeOUT");
int totTime = rs.getInt ("totalTime");
int pivot = rs.getInt ("pivotvalue");
timeINS = sdz.format(timeIN);
userIN.add(timeINS);
timeOUTS = sdz.format(timeOUT);
userOUT.add(timeOUTS);
System.out.println("User : "+userID+" |IN : "+timeIN+" |OUT : "+timeOUT+"| Total Time : "+totTime+" | PivotValue : "+pivot);
}
con.commit();
}catch (Exception e) {
e.printStackTrace();
System.out.println(e);
if (e.getCause() != null) {

check the query String I've done, that is your homework ;) so sorry answering this long, this is my first answer since I register few weeks ago to get answer.
Do not use communicate(input=""). It writes input to the process, closes its stdin and then reads all output.
Do it like this:
p=subprocess.Popen(["python","1st.py"],stdin=PIPE,stdout=PIPE)
# get output from process "Something to print"
one_line_output = p.stdout.readline()
# write 'a line\n' to the process
p.stdin.write('a line\n')
# get output from process "not time to break"
one_line_output = p.stdout.readline()
# write "n\n" to that process for if r=='n':
p.stdin.write('n\n')
# read the last output from the process "Exiting"
one_line_output = p.stdout.readline()
What you would do to remove the error:
all_the_process_will_tell_you = p.communicate('all you will ever say to this process\nn\n')[0]
But since communicate closes the stdout
and stdin
and stderr
, you can not read or write after you called communicate.
Provide a path (myfolder in this case) and just run:
git diff myfolder/
A word of caution on using $(document).ready()
with Internet Explorer. If an HTTP request is interrupted before the entire document is loaded (for example, while a page is streaming to the browser, another link is clicked) IE will trigger the $(document).ready
event.
If any code within the $(document).ready()
event references DOM objects, the potential exists for those objects to be not found, and Javascript errors can occur. Either guard your references to those objects, or defer code which references those objects to the window.load event.
I have not been able to reproduce this problem in other browsers (specifically, Chrome and Firefox)

I'm pretty sure it's manufacturer dependent, since they will be accessed through an I/O port. If you have a specific board you're trying to work with, try looking through the manuals and/or contacting the manufacturer.
If you want to do this for a lot of different boards, I'd recommend contacting someone at something like SiSoftware or be prepared to read a LOT of motherboard manuals.
As another note, not all boards have temperature monitors.
You also might run into problems getting privileged access from the kernel.
You might have some luck calling the Win32 API's MessageBoxA, although whether Win16 supports that particular method is for someone else to answer.
This tiny java method will help you produce standard CSV text of a specific column.
public static String getStandardizedCsv(String columnText){
//contains line feed ?
boolean containsLineFeed = false;
if(columnText.contains("\n")){
containsLineFeed = true;
}
boolean containsCommas = false;
if(columnText.contains(",")){
containsCommas = true;
}
boolean containsDoubleQuotes = false;
if(columnText.contains("\"")){
containsDoubleQuotes = true;
}
columnText.replaceAll("\"", "\"\"");
if(containsLineFeed || containsCommas || containsDoubleQuotes){
columnText = "\"" + columnText + "\"";
}
return columnText;
}
In my case, neither the port nor the host was the problem. The index.js
was divided into 2 files. server.js
:
//server.js
const express = require('express')
const path = require('path')
const app = express()
app.use(express.static(path.resolve(__dirname, 'public')));
// and all the other stuff
module.exports = app
//app.js
const app = require('./server');
const port = process.env.PORT || 3000;
app.listen(port, '0.0.0.0', () => {
console.log('Server is running s on port: ' + port)
});
from package.json
we ran node app.js
.
Apparently that was the problem. Once I combined the two into one file, the Heroku app deployed as expected.
Check this out. The author provides a simple but elegant solution which doesn't require any 3rd party library. http://www.ksmpartners.com/2013/08/nicely-formatted-tabular-output-in-java/
There should be no semicolon here:
class WordGame;
...but there should be one at the end of your class definition:
...
private:
string theWord;
}; // <-- Semicolon should be at the end of your class definition
this
is the DOM element on which the event was hooked. this.id
is its ID. No need to wrap it in a jQuery instance to get it, the id
property reflects the attribute reliably on all browsers.
$("select").change(function() {
alert("Changed: " + this.id);
}
You're not doing this in your code sample, but if you were watching a container with several form elements, that would give you the ID of the container. If you want the ID of the element that triggered the event, you could get that from the event
object's target
property:
$("#container").change(function(event) {
alert("Field " + event.target.id + " changed");
});
(jQuery ensures that the change
event bubbles, even on IE where it doesn't natively.)
The solution is the /Y
switch:
xcopy "C:\Users\ADMIN\Desktop\*.*" "D:\Backup\" /K /D /H /Y
We can set it using WebServerFactoryCustomizer
. This can be added directly in the spring boot main method class which starts up the Spring ApplicationContext.
@Bean
public WebServerFactoryCustomizer<ConfigurableServletWebServerFactory>
webServerFactoryCustomizer() {
return factory -> factory.setContextPath("/demo");
}
To produce a border inset within an element the only solution I've found (and I've tried all the suggestions in this thread to no avail) is to use a pseudo-element such as :before
E.g.
.has-inset-border:before {
content: "foo"; /* you need something or it will be invisible at least on Chrome */
color: transparent;
position: absolute;
left: 10px;
right: 10px;
top: 10px;
bottom: 10px;
border: 4px dashed red;
}
The box-sizing property won't work, as the border always ends up outside everything.
The box-shadow options has the dual disadvantages of not really working and not being supported as widely (and costing more CPU cycles to render, if you care).
First add an Enrty
and Category
class:
public class Entry { public string Id { get; set; } public string Title { get; set; } public string Updated { get; set; } public string Summary { get; set; } public string GPoint { get; set; } public string GElev { get; set; } public List<string> Categories { get; set; } } public class Category { public string Label { get; set; } public string Term { get; set; } }
Then use LINQ to XML
XDocument xDoc = XDocument.Load("path"); List<Entry> entries = (from x in xDoc.Descendants("entry") select new Entry() { Id = (string) x.Element("id"), Title = (string)x.Element("title"), Updated = (string)x.Element("updated"), Summary = (string)x.Element("summary"), GPoint = (string)x.Element("georss:point"), GElev = (string)x.Element("georss:elev"), Categories = (from c in x.Elements("category") select new Category { Label = (string)c.Attribute("label"), Term = (string)c.Attribute("term") }).ToList(); }).ToList();
set scan off; Above command also works.
You could do Char(13)
and Char(10)
. Cr and Lf.
Char()
works in SQL Server, I don't know about other databases.
Add the sheet name infront of the cell, e.g.:
=COUNTIFS(stock!A:A,"M",stock!C:C,"Yes")
Assumes the sheet name is "stock"
Try the below lines
$("#yourbuttonid").attr("disabled", "disabled");
$("#yourbuttonid").removeAttr("href");
Coz, Even if you disable <a>
tag href
will work so you must remove href
also.
When you want enable try below lines
$("#yourbuttonid").removeAttr("disabled");
$("#yourbuttonid").attr("href", "#nav-panel");
You can use the following if you want to specify tricky formats:
df['date_col'] = pd.to_datetime(df['date_col'], format='%d/%m/%Y')

Another alternative is KMP (Knuth–Morris–Pratt).
The KMP algorithm searches for a length-m substring in a length-n string in worst-case O(n+m) time, compared to a worst-case of O(n·m) for the naive algorithm, so using KMP may be reasonable if you care about worst-case time complexity.
Here's a JavaScript implementation by Project Nayuki, taken from https://www.nayuki.io/res/knuth-morris-pratt-string-matching/kmp-string-matcher.js:
// Searches for the given pattern string in the given text string using the Knuth-Morris-Pratt string matching algorithm.
// If the pattern is found, this returns the index of the start of the earliest match in 'text'. Otherwise -1 is returned.
function kmpSearch(pattern, text) {_x000D_

for (var i = 1; i < pattern.length; i++) {_x000D_
var j = lsp[i - 1]; // Start by assuming we're extending the previous LSP_x000D_
while (j > 0 && pattern.charAt(i) != pattern.charAt(j))_x000D_

An analysis of the various options available, and the pros and cons of each is available here.
The suggested options are:
SELECT my_column FROM my_table WHERE search_column = ?
, execute it for each value and UNION the results client-side. Requires only one prepared statement. Slow and painful.SELECT my_column FROM my_table WHERE search_column IN (?,?,?)
and execute it. Requires one prepared statement per size-of-IN-list. Fast and obvious.SELECT my_column FROM my_table WHERE search_column = ? ; SELECT my_column FROM my_table WHERE search_column = ? ; ...
and execute it. [Or use UNION ALL
in place of those semicolons. --ed] Requires one prepared statement per size-of-IN-list. Stupidly slow, strictly worse than WHERE search_column IN (?,?,?)
, so I don't know why the blogger even suggested it.SELECT my_column FROM my_table WHERE search_column IN (1,2,3,4,5,6,6,6,6,6)
. Any decent server will optimize out the duplicate values before running the query.None of these options are super great, though.
Duplicate questions have been answered in these places with equally sane alternatives, still none of them super great:
The Right Answer, if you are using JDBC4 and a server that supports x = ANY(y)
, is to use PreparedStatement.setArray
as described here:
There doesn't seem to be any way to make setArray
work with IN-lists, though.
Sometimes SQL statements are loaded at runtime (e.g., from a properties file) but require a variable number of parameters. In such cases, first define the query:
query=SELECT * FROM table t WHERE t.column IN (?)
Next, load the query. Then determine the number of parameters prior to running it. Once the parameter count is known, run:
sql = any( sql, count );
For example:
/**
* Converts a SQL statement containing exactly one IN clause to an IN clause
* using multiple comma-delimited parameters.
*
* @param sql The SQL statement string with one IN clause.
* @param params The number of parameters the SQL statement requires.
* @return The SQL statement with (?) replaced with multiple parameter
* placeholders.
*/
public static String any(String sql, final int params) {
// Create a comma-delimited list based on the number of parameters.
final StringBuilder sb = new StringBuilder(
String.join(", ", Collections.nCopies(possibleValue.size(), "?")));
// For more than 1 parameter, replace the single parameter with
// multiple parameter placeholders.
if (sb.length() > 1) {
sql = sql.replace("(?)", "(" + sb + ")");
}
// Return the modified comma-delimited list of parameters.
return sql;
}
For certain databases where passing an array via the JDBC 4 specification is unsupported, this method can facilitate transforming the slow = ?
into the faster IN (?)
clause condition, which can then be expanded by calling the any
method.
Why don't you just stack them ::
$("#clickedItem").click(function(){
$("#animatedItem").animate( // );
}).toggle( // <--- you just stack the toggle function here ...
function(){
$(this).text( // );
},
function(){
$(this).text( // );
});
#include <sstream>
and use the fully qualified name i.e. std::stringstream ss;
Here is a short piece of code I use to capture the error as a string. Will retry till it succeeds. This catches all exceptions but you can change this as you wish.
start = 0
str_error = "Not executed yet."
while str_error:
try:
# replace line below with your logic , i.e. time out, max attempts
start = raw_input("enter a number, 0 for fail, last was {0}: ".format(start))
new_val = 5/int(start)
str_error=None
except Exception as str_error:
pass
WARNING: This code will be stuck in a forever loop until no exception occurs. This is just a simple example and MIGHT require you to break out of the loop sooner or sleep between retries.
You can try this method also : example of removing last n number of lines.
a=0 ; while [ $a -lt 4 ];do sed -i '$ d' output.txt; a=
expr $a + 1
;done
Removing last 4 lines from file(output.txt).
If we think about today, accepted answer is too old. As we know that we have many new libraries which can help you to make this types of application.
You should learn following topics that will helps you surely:
SyncAdapter: The sync adapter component in your app encapsulates the code for the tasks that transfer data between the device and a server. Based on the scheduling and triggers you provide in your app, the sync adapter framework runs the code in the sync adapter component.
Realm: Realm is a mobile database: a replacement for SQLite & Core Data.
Retrofit Type-safe HTTP client for Android and Java by Square, Inc. Must Learn a-smart-way-to-use-retrofit
And your sync logic for database like: How to sync SQLite database on Android phone with MySQL database on server?
Best Luck to all new learner. :)

Iggy's answer was the easiest for me to follow, but I got the following error when doing a subsequent subplot
command that was not there when I was just doing show
:
MatplotlibDeprecationWarning: Adding an axes using the same arguments as a previous axes currently reuses the earlier instance. In a future version, a new instance will always be created and returned. Meanwhile, this warning can be suppressed, and the future behavior ensured, by passing a unique label to each axes instance.
In order to avoid this error, it helps to close (or clear) the plot after the user hits enter.
Here's the code that worked for me:
def plt_show():
'''Text-blocking version of plt.show()
Use this instead of plt.show()'''
plt.draw()
plt.pause(0.001)
input("Press enter to continue...")
plt.close()
This is explained well in the Python FAQ
What are the rules for local and global variables in Python?
In Python, variables that are only referenced inside a function are implicitly global. If a variable is assigned a value anywhere within the function’s body, it’s assumed to be a local unless explicitly declared as global.
Though a bit surprising at first, a moment’s consideration explains this. On one hand, requiring
global
for assigned variables provides a bar against unintended side-effects. On the other hand, ifglobal
was required for all global references, you’d be usingglobal
all the time. You’d have to declare asglobal
every reference to a built-in function or to a component of an imported module. This clutter would defeat the usefulness of theglobal
declaration for identifying side-effects.

this is one good answer to figure out how sorting works from another user and I will add my notes to know how it is not fully correct and what is correct:
The effect on the formula after a sort is the same as copying. A sort does not move the row contents, it copies them. The formula may (or may not depending on the abs/relative references) use new data, just as a copied formula does.
My point is that if the formula can be copied from 1 row to another and the effects don't change, the sorting will not affect the formula results. If the formulas are so complex and so dependent on position that copying them changes the relative contents, then don't sort them.
And my note that I experienced in practice:
The above user is saying right but in fact It has some exception: parts of a columns formula containing sheet name (like sheet1!A1) are treated as absolute references (in spite of copying that changes the references if they are relative ) so that part of formula will be copied without changing references relative to changing the place of formula This includes current sheet cells addressed fully like : sheet1!A2 and will be treated as absolute references(for sorting only) I tested this of excel 2010 and I do not think this issue be solved in other versions. The solution is to copy and past special as value in another place and then use sorting.
Folks above hit the right notes for storage, though if you also need to consider any PII data that needs to be stored then you can also stash into the keychain using something like https://github.com/oblador/react-native-keychain since ASyncStorage is unencrypted. It can be applied as part of the persist configuration in something like redux-persist.
The instanceof
keyword, as described by the other answers, is usually what you would want.
Keep in mind that instanceof
will return true
for superclasses as well.
If you want to see if an object is a direct instance of a class, you could compare the class. You can get the class object of an instance via getClass()
. And you can statically access a specific class via ClassName.class
.
So for example:
if (a.getClass() == X.class) {
// do something
}
In the above example, the condition is true if a
is an instance of X
, but not if a
is an instance of a subclass of X
.
In comparison:
if (a instanceof X) {
// do something
}
In the instanceof
example, the condition is true if a
is an instance of X
, or if a
is an instance of a subclass of X
.
Most of the time, instanceof
is right.
If your testing requires pulling quasi-real credit reports from the bureaus, the inactive SSNs of other answers won't work and you'll need designated test numbers.
I found this site Which appears to contain test social security numbers with associated test names and credit card numbers.
Transunion has a test environment you can link and send data to, including associated dummy credit reports. Sending a SSN to them with certain numbers in certain positions will automatically route the inquiry to their test environment Other credit bureaus will have similar systems in place.
For me it didn't work after doing all of the steps suggested in the question and in the top answer. Initially the import didn't work, and then when I restarted IntelliJ, I got these messages from the Gradle Plugin:
Gradle DSL method not found: 'annotationProcessor()'
Possible causes:<ul><li>The project 'wq-handler-service' may be using a version of the Android Gradle plug-in that does not contain the method (e.g. 'testCompile' was added in 1.1.0).
Upgrade plugin to version 2.3.2 and sync project</li><li>The project 'wq-handler-service' may be using a version of Gradle that does not contain the method.
Open Gradle wrapper file</li><li>The build file may be missing a Gradle plugin.
Apply Gradle plugin</li>
This was weird because I don't develop for Android, just using IntelliJ for Mac OS.
To be fair, my build.gradle
file had these lines in the dependencies
section, which I copied from a colleague:
compileOnly group: 'org.projectlombok', name: 'lombok', version: '1.16.20'
annotationProcessor group: 'org.projectlombok', name: 'lombok', version: '1.16.20'
After checking versions, the only thing that completely solved my problem was adding the below to the plugins
section of build.gradle
, which I found on this page:
id 'net.ltgt.apt' version '0.15'
Looks like it's a
Gradle plugin making it easier/safer to use Java annotation processors
Yes:

For my problem, I only needed to ensure that a user doesn't accidentally enter some text thus I tried to keep it simple and readable
isNumber() {

If the value of the expression is non-zero, the return status is 0
To prevent nasty error messages for strings that "might be numbers" I ignore the error output
$ (( 2s ))
bash: ((: 2s: value too great for base (error token is "2s")
If you still want a date instead of a string like the other answers, just add this extension method.
public static DateTime ToMillisecondPrecision(this DateTime d) {
return new DateTime(d.Year, d.Month, d.Day, d.Hour, d.Minute,
d.Second, d.Millisecond, d.Kind);
}
My problem was that I had a DNS entry for gitlab.example.com
to point to my load balancer. So when I tried command ssh [email protected]
I was really connecting to the wrong machine.
I made an entry in my ~/.ssh/config
file:
Host gitlab.example.com
Hostname 192.168.1.50
That wasted a lot of time...

So, you need to create a file conf/Catalina/localhost/manager.xml
and specify the rule you want to allow remote access. For example, the following content of manager.xml
will allow access from all machines:
<Context privileged="true" antiResourceLocking="false"
docBase="${catalina.home}/webapps/manager">
<Valve className="org.apache.catalina.valves.RemoteAddrValve" allow="^YOUR.IP.ADDRESS.HERE$" />
</Context>
Note that the allow attribute of the Valve
element is a regular expression that matches the IP address of the connecting host. So substitute your IP address for YOUR.IP.ADDRESS.HERE (or some other useful expression).
Other Valve
classes cater for other rules (e.g. RemoteHostValve
for matching host names). Earlier versions of Tomcat use a valve class org.apache.catalina.valves.RemoteIpValve for IP address matching.
Once the changes above have been made, you should be presented with an authentication dialog when accessing the manager URL. If you enter the details you have supplied in tomcat-users.xml
you should have access to the Manager.
For multicolumn listbox extract data from any column of selected row by
listboxControl.List(listboxControl.ListIndex,col_num)
where col_num is required column ( 0 for first column)
This solved my problem. You should select Properties, Right-Click, Source Control and Get Specific Version.
A double is an IEEE754 double-precision floating point number, similar to a float but with a larger range and precision.
IEEE754 single precision numbers have 32 bits (1 sign, 8 exponent and 23 mantissa bits) while double precision numbers have 64 bits (1 sign, 11 exponent and 52 mantissa bits).
A Double
in Java is the class version of the double basic type - you can use doubles but, if you want to do something with them that requires them to be an object (such as put them in a collection), you'll need to box them up in a Double
object.
I'm not familiar with postgresql, but in SQL Server or Oracle, using a subquery would work like below (in Oracle, the SELECT 0
would be SELECT 0 FROM DUAL
)
SELECT SUM(sub.value)
FROM
(
SELECT SUM(columnA) as value FROM my_table
WHERE columnB = 1
UNION
SELECT 0 as value
) sub
Maybe this would work for postgresql too?
mvn clean install
I think this error occurs due to the mismatch with number of columns in table definition and number of columns in the insert query. Also the length of the column is omitted with the entered value. So just review the table definition to resolve this issue
You have to specify the projectBaseDir
if the module name doesn't match you module directory.
Since both your module are located in ".", you can simply add the following to your sonar-project properties:
module1.sonar.projectBaseDir=.
module2.sonar.projectBaseDir=.
Sonar will handle your modules as components of the project:
EDIT
If both of your modules are located in the same source directory, define the same source folder for both and exclude the unwanted packages with sonar.exclusions
:
module1.sonar.sources=src/main/java
module1.sonar.exclusions=app2code/**/*
module2.sonar.sources=src/main/java
module2.sonar.exclusions=app1code/**/*

You won't get real HTML rendering to <canvas>
per se currently, because canvas context does not have functions to render HTML elements.
There are some emulations:
html2canvas project http://html2canvas.hertzen.com/index.html (basically a HTML renderer attempt built on Javascript + canvas)
HTML to SVG to <canvas>
might be possible depending on your use case:
https://github.com/miohtama/Krusovice/blob/master/src/tools/html2svg2canvas.js
Also if you are using Firefox you can hack some extended permissions and then render a DOM window to <canvas>
Your divider may not be showing due to too large dividerPadding. You set 22dip, that means the divider is truncated by 22dip from top and by 22dip from bottom. If your layout height is less than or equal 44dip then no divider is visible.
After you install the Android SDK in Eclipse
, it generates a debug signing certificate for you in a keystore called debug.keystore. The Eclipse plug-in uses this certificate to sign each application build that is generated.
Now, the problem with this debug certificate is that it is only valid for a year, or 365 days. If your Eclipse IDE uses an expired debug certificate, you will not be able to create and/or deploy an Android app
.
To fix this problem all you need to do is delete the debug.keystore file.
Go to Preferences
Android
Build
Default debug keystore
There you should see the folder where the file is located. Simply delete that file and you are good to go.

I faced the same issue where I started a node app in port 3000 and it didn't close correctly and the process kept running even after restart.
None of the taskkill or powershell commands running in Administrator mode worked for me.
I used MS Process Expoler > Properties > Image > Current directory (which was supposed to be the my project directory).
Finally, I had to reboot in SafeMode and rename the project folder and restart. The Node processes which were consuming port 3000 killed itself.
I had to solve a similar problem. I inherited a large source table from MS Access with nearly 15000 records that did not have a primary key, which I had to normalize and make CakePHP compatible. One convention of CakePHP is that every table has a the primary key, that it is first column and that it is called 'id'. The following simple statement did the trick for me under MySQL 5.5:
ALTER TABLE `database_name`.`table_name`
ADD COLUMN `id` INT NOT NULL AUTO_INCREMENT FIRST,
ADD PRIMARY KEY (`id`);
This added a new column 'id' of type integer in front of the existing data ("FIRST" keyword). The AUTO_INCREMENT keyword increments the ids starting with 1. Now every dataset has a unique numerical id. (Without the AUTO_INCREMENT statement all rows are populated with id = 0).
>>> from datetime import datetime
>>> a = datetime.now()
# wait a bit
>>> b = datetime.now()
>>> d = b - a # yields a timedelta object
>>> d.seconds
7
(7 will be whatever amount of time you waited a bit above)
I find datetime.datetime to be fairly useful, so if there's a complicated or awkward scenario that you've encountered, please let us know.
EDIT: Thanks to @WoLpH for pointing out that one is not always necessarily looking to refresh so frequently that the datetimes will be close together. By accounting for the days in the delta, you can handle longer timestamp discrepancies:
>>> a = datetime(2010, 12, 5)
>>> b = datetime(2010, 12, 7)
>>> d = b - a
>>> d.seconds
0
>>> d.days
2
>>> d.seconds + d.days * 86400
172800
Two options:
for (let item in MotifIntervention) {
if (isNaN(Number(item))) {
console.log(item);
}
}
Or
Object.keys(MotifIntervention).filter(key => !isNaN(Number(MotifIntervention[key])));
String enums look different than regular ones, for example:
enum MyEnum {
A = "a",
B = "b",
C = "c"
}
Compiles into:
var MyEnum;
(function (MyEnum) {
MyEnum["A"] = "a";
MyEnum["B"] = "b";
MyEnum["C"] = "c";
})(MyEnum || (MyEnum = {}));
Which just gives you this object:
{
A: "a",
B: "b",
C: "c"
}
You can get all the keys (["A", "B", "C"]
) like this:
Object.keys(MyEnum);
And the values (["a", "b", "c"]
):
Object.keys(MyEnum).map(key => MyEnum[key])
Or using Object.values():
Object.values(MyEnum)
If the value stored in PropertyLoader.RET_SECONDARY_V_ARRAY
is not "V_ARRAY"
, then you are using different types; even if they are declared identically (e.g. both are table of number
) this will not work.
You're hitting this data type compatibility restriction:
You can assign a collection to a collection variable only if they have the same data type. Having the same element type is not enough.
You're trying to call the procedure with a parameter that is a different type to the one it's expecting, which is what the error message is telling you.
In any case, you can override height
with max-height
.
new Chart('idName', {
type: 'typeChar',
data: data,
options: {
legend: {
display: false
}
}
});
Basically sudo expects, an executable (command) to follow & you are providing with a .
Hence the error.
Try this way $ sudo setup.sh
Windows has two different settings in which priority is established. There is the metric value which you have already set in the adapter settings, and then there is the connection priority in the network connections settings.
To change the priority of the connections:
After some more research, it appears, for Mozilla/Firefox, that Array.sort() uses mergesort. See the code here.
as noted here, this is what worked best for me:
sudo apt-get install python3 python3-pip python3-setuptools
sudo update-alternatives --install /usr/bin/python python /usr/bin/python3 10
You can try:
serial.debug_rate=9600
For firefox
Either:
<asp:TextBox id="Textbox1" runat="server" autocomplete="off"></asp:TextBox>
Or from the CodeBehind:
Textbox1.Attributes.Add("autocomplete", "off");
For this to work in Chrome the value must not have another pair of quotes.
It only works, for example, like this:
$('a[data-customerID=22]');
You need to set the "default value" for the date field to getdate()
. Any records inserted into the table will automatically have the insertion date as their value for this field.
The location of the "default value" property is dependent on the version of SQL Server Express you are running, but it should be visible if you select the date field of your table when editing the table.
This is the behaviour to adopt when the referenced object is deleted. It is not specific to Django; this is an SQL standard. Although Django has its own implementation on top of SQL. (1)
There are seven possible actions to take when such event occurs:
CASCADE
: When the referenced object is deleted, also delete the objects that have references to it (when you remove a blog post for instance, you might want to delete comments as well). SQL equivalent: CASCADE
.PROTECT
: Forbid the deletion of the referenced object. To delete it you will have to delete all objects that reference it manually. SQL equivalent: RESTRICT
.RESTRICT
: (introduced in Django 3.1) Similar behavior as PROTECT
that matches SQL's RESTRICT
more accurately. (See django documentation example)SET_NULL
: Set the reference to NULL (requires the field to be nullable). For instance, when you delete a User, you might want to keep the comments he posted on blog posts, but say it was posted by an anonymous (or deleted) user. SQL equivalent: SET NULL
.SET_DEFAULT
: Set the default value. SQL equivalent: SET DEFAULT
.SET(...)
: Set a given value. This one is not part of the SQL standard and is entirely handled by Django.DO_NOTHING
: Probably a very bad idea since this would create integrity issues in your database (referencing an object that actually doesn't exist). SQL equivalent: NO ACTION
. (2)Source: Django documentation
See also the documentation of PostgreSQL for instance.
In most cases, CASCADE
is the expected behaviour, but for every ForeignKey, you should always ask yourself what is the expected behaviour in this situation. PROTECT
and SET_NULL
are often useful. Setting CASCADE
where it should not, can potentially delete all of your database in cascade, by simply deleting a single user.
Additional note to clarify cascade direction
It's funny to notice that the direction of the CASCADE
action is not clear to many people. Actually, it's funny to notice that only the CASCADE
action is not clear. I understand the cascade behavior might be confusing, however you must think that it is the same direction as any other action. Thus, if you feel that CASCADE
direction is not clear to you, it actually means that on_delete
behavior is not clear to you.
In your database, a foreign key is basically represented by an integer field which value is the primary key of the foreign object. Let's say you have an entry comment_A, which has a foreign key to an entry article_B. If you delete the entry comment_A, everything is fine. article_B used to live without comment_A and don't bother if it's deleted. However, if you delete article_B, then comment_A panics! It never lived without article_B and needs it, and it's part of its attributes (article=article_B
, but what is article_B???). This is where on_delete
steps in, to determine how to resolve this integrity error, either by saying:
PROTECT
or RESTRICT
in Django/SQL)SET_NULL
)CASCADE
behavior).SET_DEFAULT
, or even SET(...)
).DO_NOTHING
)I hope it makes cascade direction clearer. :)
Footnotes
(1) Django has its own implementation on top of SQL. And, as mentioned by @JoeMjr2 in the comments below, Django will not create the SQL constraints. If you want the constraints to be ensured by your database (for instance, if your database is used by another application, or if you hang in the database console from time to time), you might want to set the related constraints manually yourself. There is an open ticket to add support for database-level on delete constrains in Django.
(2) Actually, there is one case where
DO_NOTHING
can be useful: If you want to skip Django's implementation and implement the constraint yourself at the database-level.
I know I'm late to the party, but whatever; I have this in my .vimrc:
nnoremap <C-d> :copy .<CR>
vnoremap <C-d> :copy '><CR>
the :copy
command just copies the selected line or the range (always whole lines) to below the line number given as its argument.
In normal mode what this does is copy .
copy this line to just below this line.
And in visual mode it turns into '<,'> copy '>
copy from start of selection to end of selection to the line below end of selection.
A single line implementation of dcastro's answer (the most compliant with other languages):
int Mod(int a, int n)
{
return (((a %= n) < 0) && n > 0) || (a > 0 && n < 0) ? a + n : a;
}
If you'd like to keep the use of %
operator (you can't overload native operators in C#):
public class IntM
{
private int _value;
private IntM(int value)
{
_value = value;
}
private static int Mod(int a, int n)
{
return (((a %= n) < 0) && n > 0) || (a > 0 && n < 0) ? a + n : a;
}
public static implicit operator int(IntM i) => i._value;
public static implicit operator IntM(int i) => new IntM(i);
public static int operator %(IntM a, int n) => Mod(a, n);
public static int operator %(int a, IntM n) => Mod(a, n);
}
Use case, both works:
int r = (IntM)a % n;
// Or
int r = a % n(IntM);
$('#textbox').live('keypress', function(e) {
if (e.keyCode === 9) {
e.preventDefault();
// do work
}
});
If you look at the examples on the api page there is this: Example: Creates a different alias instead of jQuery to use in the rest of the script.
var j = jQuery.noConflict();
// Do something with jQuery
j("div p").hide();
// Do something with another library's $()
$("content").style.display = 'none';
Put the var j = jQuery.noConflict()
after you bring in jquery and then bring in the conflicting scripts. You can then use the j
in place of $
for all your jquery needs and use the $
for the other script.
This is because label
is an inline element, and is therefore only as big as the text it contains.
The possible is to display your label
as a block element like this:
#formItem label {
display: block;
text-align: center;
line-height: 150%;
font-size: .85em;
}
However, if you want to use the label on the same line with other elements, you either need to set display: inline-block;
and give it an explicit width (which doesn't work on most browsers), or you need to wrap it inside a div
and do the alignment in the div
.
